                                                Lateral surface of a triangular prism = Length × (a + b + c)  

i hope it helps u :-)

Answer:

225 and 243.4

Step-by-step explanation:

Area of triangle = bh/2

A = 4*4.6/2

A = 9.2 cm sq

A of 2 triangles = 9.2*2 = 18.4 cm sq

Now, Area of 1 rectangle = lb --> 15*5 = 75 cm sq

A of 3 rectangles = 75*3 = 225 cm sq

Now, LSA = 225 cm sq. (excluding the triangles)

TSA = A of tr. + A of rec. = 18.4 + 225 = 243.4 cm sq

Which equation can you use to find how many roses, x, Reggie normally uses in a centerpiece?:?????????? HELP

Answers

Answer:

He normally uses 12 roses in a centerpiece

Step-by-step explanation:

The equation he can use will be,

4x - 12 = 36

Which simplified ratio correctly compares 12 yards to 20 feet? 1 yard = 3 feet

please help

Answers

Answer:

3/5

Step-by-step explanation:

Given ratio 12 yard to 20 feet,

To simplify the ratio, we first need to find the common multiples of 12 and 20,

to find the common multiples of 12 and 20, we need to factorize 12 and 20.

On factorization, we get 12= 2*2*3  and 20=2*2*5.

Common multiples of 12 and 20 are  that is 4.

And now simplifying the given ratio, 12 yard to 20 feet , that is 12/20=3/5

Answer: 3/5

Step-by-step explanation: To simplify the ratio, we first need to find the common multiples of 12 and 20 then once you find the common form there you should have your answer.

When we cross-multiply 4/3 and 1/2, we get 8 = 3

What are the translation rules?

The four translation rules are defined as follows:

Left a units: x -> x - a.Right a units: x -> x + a.Up a units: y -> y + a.Down a units: y -> y - a.

For this problem, we have that the translations are given as follows:

2 units left -> 2 is subtracted from each coordinate of x.5 units down -> 5 is subtracted from each coordinate of y.

This means that the graph that correctly shows the translation is given by option D.

He purchases a total of 150 containers of popcorn to sell. After he sells 15 containers, he will make a total profit, after his upfront costs, of $5.50. Cassidy’s profit, after upfront costs, can be modeled by a linear function in the form y=mx+b.

Question 1

Part A

What is the slope of the line that models the function?

Enter the correct answer in the box.

Answers

Answer: 208.00

Step-by-step explanation:If Cassidy sells all of the popcorn, his profit would be equal to $208.00.

What is the slope-intercept form?

Mathematically, the slope-intercept form of a line can be modeled by using this linear function:

y = mx + b

Where:

m represents the slope.

x and y are the points.

b represents the y-intercept.

How to determine Cassidy’s profit?

In order to determine Cassidy’s profit, we would have to calculate the cost of the containers of popcorn by using this mathematical expression:

Note: the price tag for a container of popcorn is one dollar and fifty cents.

Cost of containers = revenue - total profit

Cost of containers = 1.50(15) - 5.50

Cost of containers = 22.5 - 5.50

Cost of containers = $17.00

Therefore, the linear function which models Cassidy’s profit is given by:

y = 1.50x - 17

If Cassidy sells all of the popcorn, his profit is given by:

Cassidy’s profit, y = 1.50x - 17

Cassidy’s profit, y = 1.50(150) - 17

Cassidy’s profit, y = 225 - 17

Cassidy’s profit, y = $208.00

What is Cassidy’s profit if he sells all of the popcorn?

HInt: Substitute 150 for x to find the profit if all the popcorn is sold.

Answers

Answer:  Choice B

4+7x-2

========================================================

Explanation:

Combine the like terms in choice A to find that:

2x+2x+3x = 7x2-8 = -6

Therefore, choice A simplifies to 7x-6.

Choice B on the other hand simplifies to 7x+2 since 4-2 = 2.

The expressions 7x-6 and 7x+2 don't match up, which means the answer is either choice A or choice B.

--------------

Let's simplify choice C.

5x+2x = 7x-2-4 = -6

Choice C simplifies to 7x-6 which matches with choice A. In other words, choices A and C are equivalent expressions. We can rule out choice A and go with  choice B   as the final answer.

For the sake of completeness, let's simplify choice D

8x-x-6 = 7x-6

This shows choice D matches with A and C.

Choice A simplifies to 7x-6Choice B simplifies to 7x+2Choice C simplifies to 7x-6Choice D simplifies to 7x-6
