The answer is B: 150
Let a be the age at which the tree reaches maturity
289000 = 900a + 2200(220-a)
289000 = 900a + 484000 - 2200a
289000 - 484000 = -1300a
a = -19500 / -1300
a = 150
Answer:
A of each triangular base = 6 in²
A of both bases = 12 in²
Lateral A = 96 in²
Surface area = 108 in²
Step-by-step explanation:
<em>Area of each triangular base</em>
1/2(3)(4) = 1/2(12) = 6
<em>Area of both bases</em>
6*2 = 12
<em>Lateral Area</em>
(8)(3) + (8)(4) + (8)(5)
24 + 32 + 40
96
<em>Total Surface area</em>
96 + 12 = 108 in²

Answer:
52%
Step-by-step explanation:
What is the percent of change from 74 to 35 rounded to the nearest percent
Step one:
given data
initial value=74
final value= 35
Required
Percent change
Step two:
Percent change= 74-35/74*100
Percent change=39/74*100
Percent change= 0.52*100
Percent change= 52%
