Answer:
Option B
Step-by-step explanation:
Since, number of calories 'C' burned is proportional to the number of minutes (m) given to the exercise,
C ∝ m
C = km
Where k is the proportionality constant.
From the table attached,
For C = 250 calories and m = 30 minutes,
250 = 30k
k = 
= 
Therefore, equation representing this situation will be,
C = 
Option B will be the correct option.

Answer:
300mm²
Step-by-step explanation:
First we need to break up the shape into separate shapes to make it easier to work out.
<h2>Top :
×base×height</h2>
\frac{1}{2} x 15 x 30 = 225
<h2>Bottom : same formula</h2>
\frac{1}{2} x 15 x 10=75
<h2>Add them all together</h2>
225+75=300mm^2
