Answer:
5 in.
Step-by-step explanation:
Given that
b1 = 12
b2 = 8
A = 50
Formula is (1/2)h(b1 + b2), on substituting
50 = 1/2 * h(12 + 8)
50 = 1/2 * h(20)
100 = 20h
h = 100/20
h = 5
The height is 5 in

Answer:
115 mi
Step-by-step explanation:
speed = distance/time
distance = speed * time
0.5 hours at 50 mph
distance = 50 mph * 0.5 h = 25 mi
1.5 hours at 60 mph
distance = 60 mph * 1.5 h = 90 mi
total distance = 25 mi + 90 mi = 115 mi

Explanation:</h2>
Recall you need to write complete question in order to get exact answers. In this exercise, I'll assume that the complete question is:
<em>Makayla started a saving account. She starts the account with $20 and adds $80 at the end of each month. She will not remove any money from the account. How much money will she have at the end of month 11?</em>
<em />
So, she starts the account with $20, that is, this is a fixed amount of money and at the end of each month she adds 80$. So:
Let:
m: Represents the months.
s: Represents the amount of money that is saved.
We can write an equation:
So, at the beginning of the process so she have:
But at the end of month 11 she will have:
So <em>at the end of month 11 she will have $911.</em>
