Answer:
Im in middle school, please understand this. Its b.
Step-by-step explanation:
I know because well, I did the equation and rounded up and got that answer.
Given:
Total forest area = 52000 acres
Area of old growth trees in the forest = 0.4%
To find:
The area of old growth trees.
Solution:
We have,
Total forest area = 52000 acres
Area of old growth trees in the forest = 0.4%
Area of old growth trees is
Therefore, the area of old growth trees is 208 acres.
11
Step-by-step explanation:
subtract 4 from 48 which gives you 44
then divide 4 by 44 to leave t alone
that would give you 11
t equals 11
Answer:
T = 0.34r³
Step-by-step explanation:
Given that T is directly proportional to r³ then the equation relating them is
T = kr³ ← k is the constant of variation
To find k use the condition T = 21.76 when r = 4 , then
21.76 = k × 4³ = 64k ( divide both sides by 64 )
0.34 = k
T= 0.34r³ ← equation of variation
6a+15+5a-10
11a+5 this is the answer
