let t represent the total price of all items sold in dollars, and let p represent the profit in dollars.

1) WRITE AN EQUATION TO REPRESENT THE RELATIONSHIP BETWEEN THESE VARIABLES:

Pls help! I don’t understand!! :/

Answers

Answer:

p=1/5t

Step-by-step explanation:

Since t is 100% of the items sold and p is 20% of that, the profit, p is 20% of t, or 1/5t.

Answer:

p = t(0.2)

Step-by-step explanation:

The profit is 20% of the total price. So if you multiply the total price by 0.2, you will get 20% of the total price which is the profit.

The dimensions of a triangular prism are shown.
What is the surface area of the triangular prism?


A.20.5 square inches

B.29 square inches

C.32 square inches

D.14.5 square inches

Answers

Answer:

C

Step-by-step explanation:

To find surface area you find all the areas of the sides and add them up. We can start by setting up our equations.

A = L x W

For both the sides ——> 2(5 x 0.5) = 5

For both the triangle parts ——> bh/2 ———> (4 x 6)/2 times 2 = 24

For the bottom part ——> 6 x 0.5 = 3

Now to add everything up: 24 + 3 + 5 = 32

The answer should be C.

Two planes travel at a constant speed. Plane A travels 2,800 miles in 5 hours. Plane B travels 3,885 miles in 7 hours.

1. Which plane is faster?

Answers

Answer: First.

Step-by-step explanation:

Let's find the speed of the first airplane:

2800 ÷ 5 = 560 (miles per hour)

Let's find the speed of the second plane:

3885 ÷ 7 = 555 (miles per hour)

Thus, the first plane flies faster than the second.

The first plane is faster.


The first plane travels at 560 miles per hour. The comparisons are 2 hours apart. Add 560 2 times to 2800 and you get 3,920 which is greater than 3,885, the original number of MPH for the second plane.


Meaning the first plane is faster.

Write a rule for the linear function in the table.


f(x) = 4 – x

f(x) = x + 4

f(x) = x – 4

f(x) = 4x

Answers

Answer: BRAINLY

f(x)=x-4 is the answer i believe

Answer :

The function is  

Step-by-step explanation:

Given values in table :

x        f(x)

3         -1

4          0

5          1

6          2

Here we see there is a difference of 4 in the values of x and f(x)

i.e. 3-(-1)=4

or 4-0=4

Similarly 5-1=4

6-2=4

So x-F(x)=4

Adding F(x) -4 both sides

x-F(x) +F(x) -4=4+F(x) -4

We have F(x)= x-4

Solve: 2x + 3y = 1
y = -23 +11

Answers

Answer:

x = 18.5

y = -12

Step-by-step explanation:

First, solve y:

y = -23 + 11

y = -12

Then, solve the main problem:

2x + 3y = 1

(Substitute y)

2x + -36 = 1

2x - 36 = 1

2x = 1 + 36 = 37

x = 37 / 2

x = 18.5
