1) Option C is correct
2) Option B is correct
Step-by-step explanation:
Question no 1:
We need to find the constant of proportionality
The constant of proportionality can be found by using the formula y/x = k, where k is the constant of proportionality.
Finding k:
x = Hot pepper corn
y = chedder corn
So, y/x = 10/4 = 2.5
y/x = 20/8 = 2.5
y/x= 30/12= 2.5
So, Constant of proportionality is k = 2.5
Hence Option C is correct.
Question No 2
Every female rabbit has 5 baby rabbits. We need to find ratio of baby rabbits to female rabbits.
Baby rabbits = 5
female rabbits = 1
Ratio of baby rabbits to female rabbits: 5: 1 or 5/1 = 5
So, ratio of baby rabbits to female rabbits is 5
Option B is correct.

Hi.
The first thing you want to know is how many schools 60% is.
To find 60%: 4,000 x 0.6 (b/c 0.6 = 60%)
so, 60% of 4,000 = 2,400
To find the number of schools that consider SAT scores:
Subtract 2,400 from 4,000 which, equals 1,600
or
Find the remaining percentage; 40%:
4,000 x 0.4 = 1,600
Answer: 1,600 colleges
