Step-by-step explanation:
area of ∆ ACB = 1/2× AB×CP
= 1/2× 16× 21 m²
=8×21m²
= 168m²
optionC
The answer is the 3rd one
X = day # example being day 2 = x = 2
1x = how much money they have.
Ex. Day 3
x = 3
1x = 3
In 1/6 hour, 1/10 inch of snow fell.
So to find the unit rate per hour, we need to make a proportion.
1/6 is 10 minutes out of an hour so 6/6 or 1 would be an hour.
We can cross multiply. 1/10 * 1 = 1/10, 1/6 * x = 1/6x
1/6x = 1/10
Divide both sides by 1/6 to isolate x.
x = 3/5
Every hour, 3/5 inch of rain will fall.
