Q varies as e if q is 24 when e is 3 find q when e is 7

q = 56

Step-by-step explanation:

Given that q varies as e, then the equation relating them is

q = ke ← k is the constant of variation

To find k use the condition q = 24 when e = 3 , then

24 = 3k ( divide both sides by 3 )

8 = k

q = 8e ← equation of variation

When e = 7 , then

q = 8 × 7 = 56

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.
