Answer:
M = 20
Step-by-step explanation:
Given that M is directly proportional to r³ then the equation relating them is
M = kr³ ← k is the constant of proportion
To find k use the condition when r = 4, M = 160, that is
160 = k × 4³ = 64k (divide both sides by 64 )
2.5 = k
M = 2.5r³ ← equation of proportion
When r = 2, then
M = 2.5 × 2³ = 2.5 × 8 = 20
Answer: 1,400 calories
Bianca jogged 1.25 miles per day for 8 days. so 1.25*8 would equal 10 miles.
Since she jogged 10 miles and burned 140 calories per mile, if we multiply 10*140, we would get 1,400.
So last month, she lost 1,400 calories.
