A cylinder is sliced parallel to its base. The area of the cross section is 36π in2 . What is the radius of the cylinder?
If a cylinder is sliced parallel to its base. The area of the cross section is 36π inch square, then the radius of the cylinder is 6 inches
If we slice a cylinder parallel to its base, we get a circle with the same radius as the cylinder.
We are given that the area of the cross section is 36π in square units. Since the cross section is a circle, we can use the formula for the area of a circle to find the radius.
The formula for the area of a circle is:
A = πr^2
where A is the area of the circle and r is the radius of the circle.
We are given that the area of the cross section is 36π. So, we can set A = 36π and solve for r:
36π = πr^2
Dividing both sides by π:
36 = r^2
Taking the square root of both sides:
r = ±6 inches
Since radius cannot be negative, the radius of the cylinder is 6 inches

A shipment of 8 tons of sugar is separated into containers of equal size. If the shipment fills 3 3/5 containers, how much sugar can one container hold?
THIS IS TIMED HELP ME OUT
Therefore, one container can hold 20/9 tons of sugar.
To simplify this expression, we can convert the mixed number 3 3/5 to an improper fraction:
3 3/5 = (5*3 + 3)/5 = 18/5
So the expression becomes:
8 tons / (18/5) containers
To divide by a fraction, we can multiply by its reciprocal:
8 tons / (18/5) containers = 8 tons * (5/18) containers
Now we can simplify the expression and solve for the amount of sugar in one container:
8 tons * (5/18) containers = 40/18 tons/container = 20/9 tons/container

What is arithmetic progression?Arithmetic progression is the series of numbers that have common differences between adjacent values
Here,
The amount of money Sally spends on breakfast each week forms an arithmetic sequence.
Let's use the formula for the sum of an arithmetic sequence to find the first term of the sequence. We know that Sally has already spent $31.64, which means that she has made 31.64/4.52 = 7 visits to the breakfast place. So the sum of the first 7 terms of the sequence is:
S₇ = 7/2 * (a₁ + a₇)
We know that a₇ = $4.52, so we can plug this into the formula and simplify
S₇ = 7/2 * (a₁ + 4.52)
a₁ = $6.32
Similarly, all the outcomes can be evaluated,
By the end of the year, Sally will have spent $891.36 on breakfast.

A cookie recipe calls for 2 3/3 cups of flour. If Ricky wants to make 1 1/2 times the recipe. How much flour does he need?
To find out how much flour Ricky needs, we first need to find 1 1/2 times the amount of flour in the original recipe.
2 3/3 cups of flour is the same as 8/3 cups of flour.
To find 1 1/2 times the amount of flour in the original recipe, we can multiply 8/3 by 1 1/2:
8/3 x 3/2 = 24/6 + 4/6 = 28/6
So 1 1/2 times the amount of flour in the original recipe is 28/6 cups of flour.
To find out how much flour Ricky needs, we can multiply this amount by 1 1/2:
28/6 x 3/2 = 84/12 + 18/12 = 102/12
So Ricky needs 102/12 cups of flour, which simplifies to 8 1/2 cups of flour.
A circular table top of radius 1m has an inner section of radius 75cm which Is made of glass and outer section of wood.if the glass costs #2500per m²,and wood costs #1500per m²,what is the cost of the top of the table,correct to nearest naira
The cost of the top of the table, to the nearest naira, is 7678.
What is area of circle ?Area of circle can be defined as the product of pi and square of radius of circle.
The area of the circular table top can be found using the formula for the area of a circle:
[tex]A = pi*r*r[/tex]
where r is the radius of the entire circle.
[tex]A = π(1m)^2 = π m^2[/tex]
The area of the inner glass section can also be found using the same formula, but with the radius of the glass section:
A_glass =[tex]π(0.75m)^2 = 0.5625π m^2[/tex]
The area of the outer wooden section can be found by subtracting the area of the inner glass section from the area of the entire circle:
A_wood = A - A_glass = [tex]π m^2 - 0.5625π m^2 = 0.4375π m^2[/tex]
The cost of the glass section is 2500 per m², so the cost of the glass section can be found by multiplying the area of the glass section by the cost per square meter:
Cost_glass = [tex]0.5625π m^2 × 2500/m² ≈ 4418.60[/tex]
Similarly, the cost of the wooden section can be found by multiplying the area of the wooden section by the cost per square meter:
Cost_wood [tex]= 0.4375π m^2 × 1500/m² ≈ 3259.68[/tex]
The total cost of the table top is the sum of the cost of the glass section and the cost of the wooden section:
Total cost = Cost_glass + Cost_wood ≈ 7678.28
Therefore, the cost of the top of the table, to the nearest naira, is 7678.

Find m∠BDC big ideas
In the triangle BCD the value of ∠BDC is 105°.
What are triangles?
Triangles are a particular sort of polygon in geometry that have three sides and three vertices. Three straight sides make up the two-dimensional figure shown here. An example of a 3-sided polygon is a triangle. The total of a triangle's three angles equals 180 degrees. One plane completely encloses the triangle.
In ΔABC and ΔBCD it is given that -
∠A ≅ ∠B
∠ADC ≅ ∠BCD
If two angles of one triangle are congruent to two angles of another triangle, then the third angles are also congruent.
So, by the theorem stated above -
∠ACD ≅ ∠BDC
In ΔACD he sum of angles of a triangle is 180°.
The equation will be -
∠ACD + ∠ADC + ∠A = 180°
Substitute the values in the equation -
∠ACD + 30° + 45° = 180°
∠ACD + 75° = 180°
∠ACD = 180° - 75°
∠ACD = 105°
Now, since ∠ACD ≅ ∠BDC.
So, ∠BDC = 105°.
Therefore, the measure of ∠BDC is 105°.

How to make the rectangleFrom the question, we have the following parameters that can be used in our computation:
Vertices = Different quadrantsPerimeter = 28 unitsLine of symmetry = y-axisWe start by calculating the side lengths using
Perimeter = 2 * (Length + Width)
So, we have
2 * (Length + Width) = 28
Divide by 2
Length + Width = 14
Because the y-axis is a line of symmetry, then it means that the rectangle is divided into equal segments by the y-axis
Here, we can assume that
Length = Width (this is so because a square is a type of rectangle)
So, we have
Length = Width = 7
The above computations also mean that the vertices are equidistant from the axes and the origin
So, we have
Vertices = (3.5, 3.5), (3.5, -3.5), (-3.5, 3.5) and (-3.5, -3.5)

A. y=1/5x+4

C. y=−5x+4
D. y=−5x+12/5
As a result, option B is the equation of the line parallel to the specified line and passing through the point (2, 2): y = 1/5x + 12/5.
What is equation?An equation is a mathematical statement that two expressions are equal. It consists of two sides, left-hand side (LHS) and right-hand side (RHS), separated by an equals sign (=). The two sides represent the same value, so any operation performed on one side must also be performed on the other side to maintain equality.
Here,
The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. Two lines are parallel if and only if they have the same slope.
The given line has a slope of 1/5, so any line that is parallel to it must also have a slope of 1/5.
We want to find the equation of a line that is parallel to the given line and passes through the point (-2, 2). We can use the point-slope form of the equation of a line, which is:
y - y1 = m(x - x1)
where (x1, y1) is a point on the line, and m is the slope of the line. Substituting the values we have:
y - 2 = (1/5)(x - (-2))
y - 2 = (1/5)(x + 2)
Multiplying both sides by 5 to eliminate the fraction, we get:
5(y - 2) = x + 2
5y - 10 = x + 2
x = 5y - 12
This is the equation of the line that is parallel to the given line and passes through the point (-2, 2).
However, we can also rewrite the equation in slope-intercept form if we prefer. Solving for y in terms of x, we get:
x = 5y - 12
x + 12 = 5y
(1/5)(x + 12) = y
y = (1/5)x + 12/5
So, the equation of the line that is parallel to the given line and passes through the point (-2, 2) is:
y = (1/5)x + 12/5
Therefore, the equation of the line that is parallel to the given line and passes through the point (−2, 2) is option B: y = 1/5x + 12/5.

What exactly is simple interest?
Simple Interest is a simple way for computing interest on a loan or principle amount. Simple interest is a concept that is employed in numerous industries, including banking, finance, and automobiles. When you make a loan payment, the monthly interest is deducted first, followed by the principle amount.
The simple interest formula is as follows:
SI=P*R*T/100
SI stands for simple interest.
P stands for principal.
R is the interest rate (in percentage)
T denotes the length of time (in years)
The following formula is used to compute the total amount:
Amount (A) = Principal (P) x Simple Interest (SI)
Now,
As given principle=1000
