140
Step-by-step explanation:
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
Answer:
34 1/2
Step-by-step explanation:
Answer:
No, not correct.
Step-by-step explanation:
Note that 8 * 4.3 can be broken up as follows:
8 * (4 + 0.3)
and that 4*8 =32, and that 0.3(8) = 2.4 (not 0.24).
Then 8 * (4 + 0.3) becomes 32 + 2.4 = 34.4
We must know how many inches the plant grows in one month.
13 ÷ 5 = 2.6
The plant grows 2.6 inches a month.
Simply multiply 2.6 by the corresponding months to fill in the rest of the boxes.
