The surface area will be multiplied by 1/8.
What is a cone:A cone is a three-dimensional geometric shape that has a circular base and a curved surface that tapers to a point called the apex or vertex.
The height of a cone is the perpendicular distance from the vertex to the base. The radius of the base is the distance from the center of the circle to its edge.
The slant height is the distance from the vertex to any point on the edge of the base, The formula for the surface area of the cone is given by
Surface Area of the cone = πr(r + l) square unitsHere we have
A right cone has a radius of 2 ft and a slant height of 5 ft.
As we know, the total Surface Area of the cone = πr(r + l) square units
Surface Area of cone = π(2)(2 + 5) ft² = 44 ft²
Given that both the radius and slant height are multiplied by 1/4.
Radius, r = (1/4)(2) = 1/2 ft
Slant height, h = (1/4)5 = 5/4 ft
Surface Area of cone will be = π(1/2)(1/2 + 5/4) ft²
= π(1/2)(7/4) ft²
= 11/4 ft²
Let the surface area is multiplied by 'x'
=> 44x = 11/4
=> 4x = 11/4

What is the simplified form of x plus 1 over x squared plus x minus 6 divided by x squared plus 5x plus 4 over x minus 2
1 over the quantity x plus 3 times the quantity x plus 4
1 over the quantity x plus 3 times the quantity x minus 2
1 over the quantity x plus 4 times the quantity x minus 2
1 over the quantity x plus 3 times the quantity x plus 1
Answer: To simplify the expression, we can start by rewriting it as the product of the first fraction and the reciprocal of the second fraction. Then, we can factor the denominators of each fraction and simplify as much as possible.
x + 1 / (x^2 + x - 6) ÷ (x^2 + 5x + 4) / (x - 2)
= (x + 1 / (x + 3)(x - 2)) ÷ ((x + 4)(x + 1) / (x + 4)(x - 1))
= (x + 1 / (x + 3)(x - 2)) * ((x + 4)(x - 1) / (x + 4)(x + 1)) (reciprocal of second fraction)
= (x + 1 / (x + 3)(x - 2)) * (x - 1 / (x + 1)) (cancel out (x + 4) and simplify)
= (x + 1) * (x - 1) / (x + 3)(x - 2)(x + 1) (multiply the numerators and simplify)
= (x - 1) / (x + 3)(x - 2) (cancel out (x + 1) in the numerator and denominator)
Therefore, the simplified form of the expression is 1 / ((x + 3)(x - 2) / (x - 1)). This can be further simplified to:
1 / ((x + 3)(x - 2) / (x - 1)) = (x - 1) / ((x + 3)(x - 2)) * (x - 1) / 1 = (x - 1)^2 / ((x + 3)(x - 2))
So the answer is: 1 over the quantity (x + 3) times the quantity (x - 2), all multiplied by the quantity (x - 1) squared.
Step-by-step explanation:
The simplified form of the given expression is 1 over the quantity x plus 3 times the quantity x plus 4.

Mathematical expressions consist of at least two numbers or variables, at least one maths operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression.
The given expression is:
[tex]\frac{x+1}{x^2+x-6} / \frac{x^2+5x+4}{x-2}[/tex]
When a fraction is in the denominator, we take the reciprocal of the fraction and multiply it with the numerator.
So the expression becomes,
[tex]\frac{x+1}{x^2+x-6} * \frac{x-2}{x^2+5x+4}[/tex]
We can factorize the expression x² + x - 6
x² + 3x - 2x - 6
= x(x+3) -2 ( x+3)
= (x-2) (x+3)
We can also factorize the expression x² +5 x +4
x² + 4x + x +4
= x(x+4) +1 ( x+4)
= (x+1) (x+4)
Substituting these values, the expression becomes as follows:
[tex]\frac{x+1}{(x-2)*(x+3)} * \frac{x-2}{(x+1)(x+4)} = \frac{1}{(x+3)(x+4)}[/tex]
Therefore the simplified form of the given expression is 1 over the quantity x plus 3 times the quantity x plus 4.

The vertical function of the ball can be modelled using the equation h(t) = 16t^2 + 75t + 4, where h(t) is the height of the ball at time t, 16 is the acceleration due to gravity, 75 is the initial velocity of the ball, and 4 is the initial height of the ball.
What does acceleration due to gravity mean?Acceleration due to gravity is the rate of change of velocity (speed) of an object in free fall due to the force of gravity. It is denoted by g and is equal to 9.80665 m/s2 at sea level. It is the force of gravity that causes objects to fall to the ground and accelerates them as they approach the ground. When an object is in free fall, it accelerates at a rate of 9.8 m/s2. This means that after one second, the object will be travelling at 9.8 m/s, after two seconds it will be travelling at 19.6 m/s, and so on. Without the force of gravity, objects would not accelerate in free fall.
The equation h(t) = 16t^2 + 75t + 4 models the vertical function of the ball by combining the effects of acceleration due to gravity (16), initial velocity (75), and initial height (4). The term 16t^2 represents the acceleration due to gravity, which causes the ball to accelerate in the vertical direction at a rate of 16 meters per second squared. The term 75t represents the initial velocity of the ball, which causes the ball to move in the vertical direction at a rate of 75 meters per second. Finally, the term 4 represents the initial height of the ball, which is 4 meters. By combining these three effects, the equation h(t) = 16t^2 + 75t + 4 accurately models the vertical function of the ball.

help fast
Answer:
Fruit mass = 63.2 g
Biscuit mass = 94.8 g
Step-by-step explanation:
Since the ratio of fruit mass to biscuit mass is 2:3, the fraction of fruit mass to the total of fruit and biscuit mass is 2/5 and the fraction of biscuit mass to the total of fruit and biscuit mass is 3/5.
For Monkey A, the total of fruit and biscuit mass is 73 g, which means that the fraction of fruit mass is 2/5 × 73 g = 29.2 g and the fraction of biscuit mass is 3/5 × 73 g = 43.8 g. Therefore, the values for fruit mass and biscuit mass are:
Fruit mass = 29.2 g
Biscuit mass = 43.8 g
For Monkey B, the total of fruit and biscuit mass is 73 + 85 = 158 g, which means that the fraction of fruit mass is 2/5 × 158 g = 63.2 g and the fraction of biscuit mass is 3/5 × 158 g = 94.8 g. Therefore, the values for fruit mass and biscuit mass are:
Fruit mass = 63.2 g
Biscuit mass = 94.8 g

When will the plane be at an altitude of three thousand feet?
Question 1
How long before the plane touches down on the runway?
Question 2
The units for the amount of time that the plane descends are minutes, and the units for the plane's altitude are feet. Let's define a variable t for the amount of time that the plane descends. Then we can write an expression for the plane's altitude in terms of t as:
Altitude = 34,000 - (1,000 * t)
This expression represents the plane's initial altitude of 34,000 feet, minus the rate of descent (1,000 feet per minute) times the amount of time that the plane descends.
To find when the plane will be at an altitude of 3,000 feet, we can set the expression equal to 3,000 and solve for t:
3,000 = 34,000 - (1,000 * t)
31,000 = 1,000 * t
t = 31
So the plane will be at an altitude of 3,000 feet after 31 minutes of descent.
To find how long before the plane touches down on the runway, we can set the expression equal to 0 and solve for t:
0 = 34,000 - (1,000 * t)
34,000 = 1,000 * t
t = 34
So the plane will touch down on the runway after 34 minutes of descent.

The mean and standard deviation of a population are 200 and 20, respectively. Sample size is 25. What is the mean of the sampling distribution?.
The mean of the sampling distribution is 200, and the standard deviation of the sampling distribution is 4.
The sampling distribution is a theoretical distribution that represents the behavior of sample means from all possible samples of a given size that can be drawn from a population.
However, the standard deviation of the sampling distribution is not the same as the standard deviation of the population.
Mathematically, we can represent the mean of the sampling distribution as follows:
μ(x) = μ = 200
Where μ(x) represents the mean of the sampling distribution and μ represents the mean of the population.
We can also calculate the standard error of the mean using the following formula:
σ(x) = σ / √(n)
Where σ(x) represents the standard deviation of the sampling distribution, σ represents the standard deviation of the population, and sqrt(n) represents the square root of the sample size.
Plugging in the values given in the problem, we get:

During a drought, the cost of corn increases. Suddenly, gasoline costs $3.86 per gallon. A diesel truck uses 4 gallons to drive 60 miles. With the increased cost of gasoline, is it cheaper to drive the old truck or the diesel truck?
It is cheaper to drive the old truck, which costs $11.58 to drive 60 miles, compared to the diesel truck, which costs $15.44 to drive the same distance, given the current fuel prices.
Describe Algebraic Expression?An algebraic expression is a mathematical phrase that consists of variables, numbers, and mathematical operations such as addition, subtraction, multiplication, and division. It is a combination of constants, variables, and operators that represent a value or a relationship between values.
For example, "3x + 5" is an algebraic expression where "3" and "5" are constants, "x" is a variable, and "+" is an operator. The expression can be evaluated by substituting a value for "x" and performing the necessary operations.
Algebraic expressions can also be simplified by combining like terms and using the rules of arithmetic to simplify the expression. For instance, the expression "2x + 3x" can be simplified to "5x" by adding the coefficients of the like terms "x".
Algebraic expressions are used extensively in algebra to represent equations and relationships between variables. They are also used in a wide range of mathematical and scientific applications, including physics, engineering, and finance.
To compare the cost of driving the old truck to the diesel truck, we need to know the fuel efficiency of the old truck. Let's assume that the old truck uses gasoline and has a fuel efficiency of 20 miles per gallon.
To drive 60 miles, the old truck will use 60/20 = 3 gallons of gasoline.
At $3.86 per gallon, the cost of 3 gallons of gasoline is 3 * $3.86 = $11.58.
The diesel truck uses 4 gallons of diesel to drive 60 miles. The cost of diesel is not given in the problem, so we'll assume it's the same as the cost of gasoline, $3.86 per gallon.
At $3.86 per gallon, the cost of 4 gallons of diesel is 4 * $3.86 = $15.44.
Therefore, it is cheaper to drive the old truck, which costs $11.58 to drive 60 miles, compared to the diesel truck, which costs $15.44 to drive the same distance, given the current fuel prices.

What is a Variable?A variable is something that may be changed in the setting of a math concept or experiment. Variables are often represented by a single symbol. The characters x, y, and z are often used generic symbols for variables. Variables are characteristics that can be examined and have a large range of values.
A semi-variable cost (Mixed)
Cost A's overall cost rises as manufacturing volume grows, but the per-unit cost stays the same. This implies that there are two types of costs: fixed and variable.
B: Variable Cost
The manufacturing volume directly correlates with the overall cost of Cost B. This suggests that the price is purely arbitrary.
Price C: Fixed
Regardless of the volume of output, the overall cost of Cost C is constant. This suggests that the price is set in its entirety.
D: Variable Cost
The manufacturing volume directly correlates with the overall cost of Cost D. This suggests that the price is purely arbitrary.
Variable, semivariable, fixed, and variable is the right answer, hence it is (D).

The maximum total deduction that can be claimed is OE. $17,100.
What is deduction ?
Deduction refers to the process of subtracting or taking away something. In the context of taxes, a deduction is a specific amount of money that a taxpayer is allowed to subtract from their income before calculating their tax liability. Deductions are one way to reduce the amount of taxes owed and can help to lower a person's overall tax burden.
There are two main types of deductions in the U.S. tax system: standard deductions and itemized deductions. The standard deduction is a fixed amount that varies depending on the taxpayer's filing status, while itemized deductions are specific expenses that a taxpayer can deduct from their taxable income. Some common examples of itemized deductions include mortgage interest, charitable contributions, medical expenses, and state and local taxes.
It's important to note that not all deductions are available to all taxpayers, and there are specific rules and limits that apply to each type of deduction. It's also important to keep accurate records and documentation to support any deductions that are claimed on a tax return.
The maximum total deduction that can be claimed is OE. $17,100, because that is the sum of the deductible expenses and the standard deduction.
The question is asking for the maximum total deduction that can be claimed, given certain deductible expenses and a standard deduction.
The standard deduction for the tax year is $6,100, and the deductible expenses are $6,000 in mortgage interest and $5,000 in charitable contributions.
Since the deductible expenses ($6,000 + $5,000 = $11,000) are less than the standard deduction of $6,100, it makes sense to use the standard deduction instead of itemizing deductions.
Therefore, the maximum total deduction would be the sum of the deductible expenses and the standard deduction:
$11,000 + $6,100 = $17,100
So, the maximum total deduction that can be claimed is OE. $17,100.

A television manufacturer produces x sets per week so the total cost of production is given by relation C(x)=x²-195x² +66000x+15000 find how many television sets must be manufacturer per week to minimize the total cost.
We require x = 170 televisions to minimize total cost
What is the minimum of a function?The minimum of a function is the lowest value of that function.
How to find how many television sets must be manufacturer per week to minimize the total cost.?Given that a television manufacturer produces x sets per week so the total cost of production is given by relation C(x) = x² - 195x² + 66000x + 15000.
To find the minimum value, we differentiate C(x) with respect to x and equate to zero.
So, C(x) = x² - 195x² + 66000x + 15000
dC(x)/dx = d(x² - 195x² + 66000x + 15000)/dx
= dx²/dx - d195x²/dx + d66000x/dx + d15000/dx
= 2x - 195(2)x + 66000 + 0
= 2x - 390x + 66000
= -388x + 66000
Equating to zero, we have
dC(x)/dx = 0
-388x + 66000 = 0
-388x = -66000
x = -66000/-388
x = 170.1
x ≅ 170
So, we require x = 170 televisions to minimize total cost

Answer:
A commonly used fraction that helps you understand a different size or amount is called a ratio.
Step-by-step explanation:
A ratio is a comparison of two or more quantities or measurements, expressed as a fraction or a colon. Ratios are commonly used to express the relationship between different amounts or sizes, and they can be used to help solve problems involving proportions, rates, and percentages. For example, if you are making a recipe that calls for two cups of flour and one cup of sugar, the ratio of flour to sugar is 2:1, or 2/1. Ratios can also be expressed in decimal or percentage form!
The sum of the ages of Farhan and his cousin is 38. Seven years ago, Farhan was thrice as old as his cousin. Find Farhan's present age.
Answer:
25
Step-by-step explanation:
let farhan's age be x and his cousin's age be y
sum of ages = x + y = 38
7 years ago (so x-7 and y-7), farhan was thrice as old as his cousin, so 3 * his cousin's past age = farhan's past age= 3 *(y-7) = x-7
subtract y from both sides in the first equation to solve for x
x = 38-y
substitute this into the second equation
3 *(y-7) = 38-y-7
3y-21 = 31-y
add y to both sides to put all y values on one side
4y -21 = 31
add 21 to both sides to solve for y
4y = 52
y = 13
sum of ages = x + y = 38 = 13 + x so x = 25 = 38-13
The point P(4, 28) lies on the curve y = x² + x + 8. If Q is the point (x,x² + x + 8), find the
slope of the secant line PQ for the following values of x.
For x = 4.1:
Slope of PQ =5.1
For x = 4.01:
Slope of PQ =6.01
For x = 3.9:
Slope of PQ =15.1
For x = 3.99:
Slope of PQ =105.99
From the results above, we can guess that the slope of the tangent line to the curve at P is approximately 6.
Step by step explanationTo find the slope of the secant line PQ, we need to first find the coordinates of point Q in terms of x:
Q = (x, x² + x + 8)
Then, the slope of the secant line PQ is given by:
(yQ - yP) / (xQ - xP)
where yP = 28 and xP = 4, and yQ and xQ depend on the value of x.
For x = 4.1:
Q = (4.1, 4.1² + 4.1 + 8) = (4.1, 28.51)
Slope of PQ = (28.51 - 28) / (4.1 - 4)
= 0.51 / 0.1
= 5.1
For x = 4.01:
Q = (4.01, 4.01² + 4.01 + 8) = (4.01, 28.0601)
Slope of PQ = (28.0601 - 28) / (4.01 - 4)
= 0.0601 / 0.01
= 6.01
For x = 3.9:
Q = (3.9, 3.9² + 3.9 + 8) = (3.9, 26.49)
Slope of PQ = (26.49 - 28) / (3.9 - 4)
= -1.51 / -0.1
= 15.1
For x = 3.99:
Q = (3.99, 3.99² + 3.99 + 8) = (3.99, 26.9401)
Slope of PQ = (26.9401 - 28) / (3.99 - 4)
= -1.0599 / -0.01
= 105.99
As x approaches 4 from both sides, the x-coordinate of Q approaches 4, and the slope of PQ approaches the slope of the tangent line to the curve at P(4,28). From the results above, we can guess that the slope of the tangent line to the curve at P is approximately 6.
