Answer:


Step-by-step explanation:
Given


Required
Determine the number of boys and girls
We have to convert the ratio to fraction;
Number of girls can be calculated as:








Slope tells the steepness of the graph
y=mx+b
m=slope
so if m is bigger,t hen sloe is bigger
y=5x+0
slope is 5
y=1x+500
slope is 1
y=5x is steeper
B :)))))))))))))))))))))))))))))))))))))))))))))((
8/12 and 2/3
7/10 and 21/30
These are the ones that are equivalent. The others are not.
Here d varies directly with cube of w, and inversely with p. So w cube have to be in the numerator and p have to be in the denominator. And we need to use k for constant of proportionality. Therefore the required equation is

In direct proportionality, the relatioship is linear that is as w increases, d increases and as w decreases d decreases and for inverse, it is opposite .
