Step One
Find the area of the base
A = s * s
s = 755.5 feet
Area = 755.5^2
Area = 570780.25 square feet.
Step two
Multiply the volume by 3
V = 1/3 B * h
3*V = B * h
V = 85600000
85600000 * 3 = B * h
256800000 = B * h
Step Three
Divide by B
B = 570780.25
256800000 = 570780.25 * h
256800000 / 570780.25 = h
449.91 feet = h
You would just do 4 x 7, which means there are 28 combinations.
Answer:
There are 180 milligrams of gold in the alloy
Step-by-step explanation:
because i know
20%, because if 65 is 100, then 52 is 80% out of 65; so 100 - 80 is 20
(-3/4m) -(1/2)=2+(1/4m)
-(1/2)=2+m
m= -3/2
