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}](https://tex.z-dn.net/?f=%20%5Cfrac%7B62.5%7D%7B100%7D%20)
:
Painted area=
![(4000)(\frac{62.5}{100})=2500](https://tex.z-dn.net/?f=%284000%29%28%5Cfrac%7B62.5%7D%7B100%7D%29%3D2500)
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](https://tex.z-dn.net/?f=%20%5Cfrac%7B2500%7D%7B5.75%7D%20%3D434.78)
We can conclude that Kyler paints at a rate of
434.78 square feet per hour.
Answer:
17.37
Step-by-step explanation:
y varies inversely as the square root of x
Mathematically:
y = k.root x
We first find k here
To find k, we were made to know that y is 21 and x = 361
k = y/root.x
k = 21/root. 361
k = 21/19
now what is y when x = 247
From y = k.root x
y = 21/19 * root 247
y= 21/19 * 15.72
y = 17.37
Depositing means that you added 50$ to your account. This means that you account increased by an amount of 50.
The integer describing this is +50.
Then, withdrawing means that you took money from the account. This means that your account decreased by an amount of 20.
This can be expressed as a -20 integer.
