You are wallpapering a wall 10 feet wide and 12 feet high with a square window with 3 foot sides. How many square feet of wallpa

kolbaska11 [484]

Hey there!

First you need to see how much you need to buy, and when you do 10 x 12 = 120.

So you need at least 120 feet to cover the wall.
Now you have to factor in the wall, when you do 3 x 3 (B x H) = 9.
Now do, 120 - 9 = 111.

So you need 111 square feet to cover the wall.

Hope this helps!

Make h the subject of the formula d= square root of 4h/5

Anna007 [38]

The formula after making h the subject of formula is: $h=\frac{5d^2}{4}$

Further explanation:

Given formula is:

$d=\sqrt{\frac{4h}{5}}\\$

Making any variable subject of any formula means that the concerned variable should be isolated on one side of the formula. Which means it will be a dependent quantity.

So,

First of all we have to take the h out of the square root

So,

$Taking\ square\ on\ both\ sides\\(d)^2=(\sqrt{\frac{4h}{5}})^2\\d^2=\frac{4h}{5}\\Multiplying\ both\ sides\ by\ 5\\5d^2=\frac{4h}{5}*5\\5d^2=4h\\Dividing\ both\ sides\ by\ 4\\\frac{5d^2}{4}=\frac{4h}{4}\\h=\frac{5d^2}{4}$
