Grady lists three different expressions below. Determine which expression is not equivalent to the others.
The third expression i.e. a(b) + a(c) is not equivalent to the other expressions. The solution has been obtained by using the algebraic expressions.
What is an algebraic expression?
A mathematical phrase is said to as "algebraic" if it contains variables, constants, and algebraic operations (addition, subtraction, etc.).
We are given three expressions.
The first expression is a + b+ c which represents the sum of the three variables.
The second expression is c + b + a which also represents the sum of the three variables but just the order of adding is different.
The third expression is a(b) + a(c) which represents sum of two variables multiplied with the third variable.
Hence, the third expression i.e. a(b) + a(c) is not equivalent to the other expressions.

The areas and the perimeters of the composite figures are listed below:
Case 1: A = 36 cm² (Right choice: A)
Case 2: p = 30 cm (Right choice: G)
Case 3: A = 46 cm² (Right choice: I)
Case 4: p = 38 cm (Right choice: H)
How to determine the perimeter and the area of a composite figure
In this problem we find two composite figures that are result of combining three rectangles, whose perimeters are the sum of all side lengths and whose areas are the sum of the areas of the rectangles. The formulae for the perimeter and the area of a rectangle are, respectively:
Perimeter
p = 2 · (w + l)
Where:
p - Perimeter, in centimeters.w - Width, in centimeters.l - Height, in centimeters.Area
A = w · l
Where A is the area, in square centimeters.
Now we proceed to determine the perimeters and areas according to the case:
Case 1
A = 2 · (3 cm) · (5 cm) + (2 cm) · (3 cm)
A = 30 cm² + 6 cm²
A = 36 cm² (Right choice: A)
Case 2
p = 2 · (3 cm) + 3 · (2 cm) + 2 · (5 cm) + 8 cm
p = 6 cm + 6 cm + 10 cm + 8 cm
p = 30 cm (Right choice: G)
Case 3
A = 2 · (5 cm) · (4 cm) + (2 cm) · (3 cm)
A = 40 cm² + 6 cm²
A = 46 cm² (Right choice: I)
Case 4
p = 2 · (4 cm) + 2 · (5 cm) + 2 · (2 cm) + 3 cm + 13 cm
p = 8 cm + 10 cm + 4 cm + 3 cm + 13 cm
p = 38 cm (Right choice: H)

Do not include units (cubic units) in your answer.
The volume of the triangular prism is 137.2 units cube.
How to find the volume of a triangular prism?The triangular prism has a height of 8 units. The base of the prism is shown in the image. The volume of the prism can be represented as follows:
volume of a triangular prism = BH
where
B = base areaH = heightTherefore, let's find the base area
B = 1 / 2 b h
let's find b
Hence,
tan 65 = b / 4

if 2 apples can be bought in Rs 48 , how many apples can be bought in Rs 1098 ?
don't spam-
tysm! :)
Answer:
Rs 1098 can buy 45.75 apples (or approximately 45 apples, since we cannot buy a fractional part of an apple).
Step-by-step explanation:
We can use proportionality to solve this problem. Since the price of apples is directly proportional to the number of apples, we can set up a proportion:
2 apples / Rs 48 = x apples / Rs 1098
To solve for x, we can cross-multiply and simplify:
2 * Rs 1098 = 48 * x
Rs 2196 = 48x
x = Rs 2196 / 48
x = 45.75
Therefore, Rs 1098 can buy 45.75 apples (or approximately 45 apples, since we cannot buy a fractional part of an apple).

What is a variable defined as?A variable is a number in mathematics that can change depending on the issue. Several statements and equations in mathematics use the generic letters x, y, and z. Or to put it another way, a variable is a symbol that denotes an unknowable numerical value. Assume that x + 5 = 10. The term "x" is used here.
Since y varies directly with x, we know that the ratio of y to x is constant. Let's call this constant k. Then we can write:
y = kx
To find k, we can use the first two rows of the table:
When x = 2, y = 3, so:
3 = k(2)
k = 3/2
When x = 10, y = 15, so:
15 = k(10)
k = 3/2 (which matches the previous calculation)

Biking at 10 mph, it takes Kristen 1/4 hour to reach the train station to go to work. Kristen then takes the train to work, and it takes another 1/4 hour for her to get to work when the train travels 28 mph. How far does Kristen travel to work?
a- 37.5

The requried Kristen travels 9.5 miles to work. Option D is correct.
What is speed?Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.
Here,
We can use the formula distance = rate x time to solve this problem.
When Kristen is biking, her rate is 10 mph and her time is 1/4 hour. So her distance traveled is:
distance = rate x time
distance = 10 mph x 1/4 hour
distance = 2.5 miles
When Kristen is on the train, her rate is 28 mph and her time is another 1/4 hour. So her distance traveled on the train is:
distance = rate x time
distance = 28 mph x 1/4 hour
distance = 7 miles
Therefore, the total distance Kristen travels to work is the sum of the distances she traveled while biking and on the train:
total distance = distance biked + distance on train
total distance = 2.5 miles + 7 miles
total distance = 9.5 miles
So Kristen travels 9.5 miles to work.

The 90% confidence interval for the mean number of books people read is (-16, 38.6).
How to construct a 90% confidence interval for the mean number of books people read?To construct a 90% confidence interval for the mean number of books people read, we first need to find the critical value (z*) that corresponds to a 90% confidence level. This can be found using a z-table or calculator. The critical value for a 90% confidence level is 1.645.
Next, we need to calculate the margin of error (ME) using the formula ME = z* x SE, where SE is the standard error. In this case, SE = 16.6 books, so ME = 1.645 x 16.6 = 27.3 books.
Finally, we can construct the 90% confidence interval by adding and subtracting the margin of error from the sample mean (x overbar). The confidence interval is:
(x overbar - ME, x overbar + ME) = (11.3 - 27.3, 11.3 + 27.3) = (-16, 38.6)
This means that we are 90% confident that the true mean number of books people read is between -16 and 38.6 books.

Answer:
PQ is 35.6 units.
Step-by-step explanation:
From the problem, we can see that the smaller quatilateral is 4x smaller than the bigger one. We can multiply 8.9 by 4 to get 35.6 units.
One number exceeds another by 1. The sum of the numbers is 25. What are the numbers?
Let's call the smaller number "x". Since the larger number exceeds the smaller number by 1, we can call the larger number "x + 1".
The problem tells us that the sum of the numbers is 25, so we can set up an equation:
x + (x + 1) = 25
Simplifying and solving for x:
2x + 1 = 25
2x = 24
x = 12
So the smaller number is 12. To find the larger number, we can use x + 1:
x + 1 = 12 + 1 = 13
So the larger number is 13.
Therefore, the two numbers are 12 and 13.

X/-3 is greater or equal to 23
The solution to the inequality is any value of X that is less than or equal to -69.
What is Inequality?
An inequality is a relationship that compares two numbers or other mathematical expressions that are not equal. It is most commonly used to compare the sizes of two numbers on a number line.
The inequality X/(-3) ≥ 23 can be solved as follows:
We begin by multiplying both sides of the inequality by -3, which will reverse the direction of the inequality since we are multiplying by a negative number. This gives:
X ≤ -69
Therefore, the solution to the inequality is any value of X that is less than or equal to -69.

What is cartesian plane ?
A Cartesian plane (also known as a coordinate plane or rectangular coordinate system) is a two-dimensional plane formed by two perpendicular number lines, referred to as the x-axis and the y-axis, that intersect at a point called the origin. The x-axis is a horizontal line, and the y-axis is a vertical line.
Explanation:
To plot the following points in the Cartesian plane:
{(3,6),(-8,2),(-9,-4),(2,-8)}
First, we draw the x and y axes to form a Cartesian plane.
Then, for each point, we plot the x and y coordinates on the graph. The x coordinate indicates the horizontal position of the point on the x-axis, while the y coordinate indicates the vertical position of the point on the y-axis.
The point (3,6) is plotted as a dot on the Cartesian plane located 3 units to the right of the origin on the x-axis and 6 units above the origin on the y-axis.
The point (-8,2) is plotted as a dot located 8 units to the left of the origin on the x-axis and 2 units above the origin on the y-axis.
The point (-9,-4) is plotted as a dot located 9 units to the left of the origin on the x-axis and 4 units below the origin on the y-axis.

h(-2) = 3
h(0) = 0
h(5) = 3/4
This can be solved by using the concept of function.
What is function?In arithmetic, a function from one set to another, X to Y, allocates precisely one element of Y to each element of X. Both of the set X and the set Y usually known as the function's domain and codomain, respectively. The basic conception of functions was the relationship between fluctuating quantities and other variables.
A function with the name f is defined by the formula y=f(x). This is understood to mean "y is a function of x." The input value, also known as an independent variable, is represented by the letter X. The outcome value, or dependent variable, is denoted by the letter y, or f(x).
This is a piece wise-defined function:
For h(-2):
h(-2) = 3
For h (0):
h(0) = (x + 1)²- 1
h(0) = (0 + 1)² - 1
h(0) = 1 - 1
h(0) = 0
For h(5):
h(5) = -1/4 x + 2
h(5) = -1/4(5) + 2
h(5) = 3/4

FILL IN THE BLANK question 1 options: two polygons are similar if and only if there is a correspondence among their angles and among their sides so that all corresponding angles are ___and all corresponding sides are proportional.
Two polygons are similar if and only if all corresponding angles are congruent and all corresponding sides are proportional. The solution has been obtained by using concept of similar quadrilaterals.
What are similar quadrilaterals?
Two quadrilaterals are considered to be similar when two adjacent sides have the same ratio and all three matching angles are equal (the fourth angle automatically becomes equal because the internal angle sum equals 360 degrees).
Two polygons are similar if and only if there is a correspondence among their angles and among their sides so that all corresponding angles are congruent and all corresponding sides are proportional.

Describe Equation.An equation is a mathematical statement that expresses the equality between two mathematical expressions or values. It is a concise representation of a relationship between two or more variables, which can be represented using symbols or numbers. An equation usually consists of two sides separated by an equal sign, where each side represents a mathematical expression.
Equations are used in various branches of mathematics, science, engineering, and other fields to describe various phenomena and solve problems. They play a crucial role in understanding and describing real-world phenomena, from the laws of physics to the behavior of financial markets. Equations can help us predict outcomes, design solutions, and solve complex problems.
In mathematics, equations are used to solve problems that involve unknown variables. The unknown variables can be found by manipulating the equation to isolate the variable. Solving equations is a fundamental skill in mathematics, and it is often used in fields like physics, chemistry, and engineering.
Equations can be linear or nonlinear, depending on the degree of the variables involved. Linear equations involve variables raised to the first power only, while nonlinear equations involve variables raised to higher powers or are composed of a combination of functions.
In summary, equations are a fundamental tool in mathematics and other fields, which help us describe and understand the relationships between variables and solve problems involving unknown variables.
To find the first positive time at which the particles have approximately the same velocity, we need to find the derivative of the displacement function for each particle, set them equal to each other, and solve for x.
The derivative of the displacement function for particle 1 is:
f'(x) =[tex]-4e^(4[/tex]cos(x))sin(x)
The derivative of the displacement function for particle 2 is:
g'(x) =[tex]-x^2 - x[/tex]
Setting f'(x) equal to g'(x), we get:
[tex]-4e^(4[/tex]cos(x))sin(x) =[tex]-x^2 - x[/tex]
We can solve this equation numerically using a graphing calculator or computer software. The first positive solution is approximately x = 1.011. Therefore, the answer is D. x= 1.011.
