Word Problem: Sophie and Joan need to determine whether or not they have enough paint to paint the walls of their bedroom. They need 2 6/7 gallons of paint in order to cover the entire room. Sophie has brought 5/6 of a gallon of paint. What is the minimum amount of paint Joan needs to bring in order to paint the entire wall?

Answer: 2 1/42 gallons

Solving Steps:

  • 2 6/7 - 5/6 (needs to be simplified)
  • 6/7 x 6/6 = 36/42
  • 5/6 x 7/7 = 35/42
  • 36/42 - 35/42 = 1/42
  • 2 + 1/42 = 2 1/42
  • Final Answer: 2 1/42 gallons

I hope this helps!! :)

Calculate the average rate of change for the given graph from x = 3 to x = 5 and select the correct answer below. parabolic func
storchak [24]

Answer:

0

Step-by-step explanation:

The question lacks the graph to be able to solve it, I was doing a little research and I could find the graph which I will attach:

Already with the figure we can solve the question.

We have that the average exchange rate in this case would only take the normal slope between those 2 lines

. Furthermore we know that the slope (m) is given by:

m = (y2-y1) / (x2 - x1)

From the graph we have to:

y2 = 0

y1 = 0

x2 = 5

x1 = 3

we replace:

m = (0-0) / (5 - 3)

m = 0

Therefore the average rate is 0.

Solve the following inequality. Negative one-half p less-than negative 16 Which graph shows the correct solution?
Irina18 [472]

Answer:

p > 10.67

Step-by-step explanation:

Given the inequality -1 1/2p < -16

Before we can represent the inequality on a graph we just simplify it first. On simplification:

-1 1/2p < -16

(-3/2)p < -16

Multiplying both sides by 2

-3p < -32

Dividing both sides by -3 will change the sense of the inequality as shown:

p > -32/-3

p > 32/3

p > 10.67

Find the graph of the resulting inequality in the attachment.
