The elevation of a building's basement is -12 feet. Given the building is square shaped and the total length of the building from basement to roof is 62 feet, what is the elevation of the building above ground?

In a flock of sheep 34%of them are white If 85 of the sheep are white how many total sheep in the flock

Answers

250 sheep in the flock


hope this helps

<3
The number of the white sheeps is 34% of the total sheeps. That means
34% × total sheeps = white sheeps

Input the number
34% × total sheeps = 85

Change percent into decimal
0.34 × total sheeps = 85
total sheeps = \cfrac{85}{0.34}
total sheeps = 250

There are 250 sheeps
