You are painting the walls and ceiling of a rectangular 20 x 30 ft room. The walls are 10 feet tall. You need two coats of paint

Mkey [24]

Answer:

$424

Step-by-step explanation:

Find area of all surfaces to be covered

20 x 30 = 600 ceiling

10 x 20 = 200 x 2 = 400 two walls

10 x 30 = 300 x = 600 other two walls

Assume no doors

total area is 1600 square feet

multiply by 2 because you are doing two coats

3200 total area to be covered

3200/400 = 8 gallons of paint x $53 = $424

For the function f defined below, what is the value of f(-1)? fx=x+3<br> -----<br> 2

Pepsi [2]

Answer:

6) C 1

7) A 3 (im not sure for this one because it's blurry)

8) C 1

Step-by-step explanation:

6) Replace the f(x) for -1 since we are told f(x) = -1. We then need to use the inverse operation to get x by itself.

$- 1 = \frac{x - 3}{ 2}$

Since the opposite of division (which is indicated by the fraction line) is multiplication, we need to multiply the number on the left (-1) times 2.

$- 2 = x - 3$

For this step, the opposite of subtraction is addition so in this step, we must add 3 to -2.

$1 = x$

7) Can't explain cause I'm not sure if I'm right

8) To find out the slope of two coordinates we must use the following to determine it.

<h3>(IN THE PICTURE ATTACHED)</h3>

In this case, the y with the little two will be 4 and the y with the little one is 1. 4-1 is 3 and that's the y cooridnate sorted

For the x coordinate, the x with the little two is 1 and the x with the little one is -2. Thus, we must solve 1-(-2) which also equals 3.

<h3>Since the final coordinates are 3/3 and it simplifies, the final answer is 1.</h3>
