After 5.75 hours, Kyler had finished painting 62.5% of his house. He needs to paint a total of 4,000 square feet on his house. A
MissTica
First, we are going to find the painted area of his house. We know that the total area he needs to paint is 4000 square meters, so 4000 is the area of this house. Now, to find the 62.5% of that area, we are going to multiply it by \frac{62.5}{100}:
Painted area= (4000)(\frac{62.5}{100})=2500

Now, to find <span>rate, in square feet per hour, we are going to divide the painted area by the number of hours: 
Rate=</span>\frac{2500}{5.75} =434.78

We can conclude that Kyler paints at a rate of 434.78 square feet per hour.

the amount y of your friends allowances if the amount she receives is 2$ more than the amount x you receive
liberstina [14]

Hello, How are you doing today?

If your friend makes 2$ more than you do, then you must form an equation for the problem. y = amount she has, x = your amount. Therefor, it would be:

y = x + 2

If you make 6 dollars, she will make 8 and so on. Thank you, have a nice day!
