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.

Let U = {all integers}.

elixir [45]

All integer numbers are either even or odd. So, the complement to the set B (to the set of all even integers) is the set of all odd integers, that is D.

The integer number of the form 2x is always even, because it is always divided by 2, so the set C is the empty set.

Numbers 1, 3, 5, 7 are odd, therefore they belong to the set D.
