Answer:
The support post positioned 23 feet far from the front of the house
Step-by-step explanation:
According to Pythagoras Theorem
(Hypotenuse)² = (Base)² + ( Perpendicular)²
We need to find Base so arranging the equation will give us
(Base)² = (Hypotenuse)² - ( Perpendicular)²
Taking under root on both sides
Base = √(Hypotenuse)² - ( Perpendicular)²
Base = √ (625 - 100)
Base = √525
Base = 23 feet
Answer:
40 if i did the equation right and ignore this wiehdnsjw
So, look:
36*4 = 144
There are 145 quarters in all.
And in nickels, there are:
144 * 5 = 720 + 5 = 725
There are 725 nickels in all.
Dimes: 144 * 10 = 1440 + 10 = 1450 (or you could do 145 * 10 and still get 1450. Like I did in the nickels and everything. :) )
= 1450 dimes
I hope this helps!
