A math degree at St. Louis University requires students to complete about 42 classes. A physics degree at St. Louis University requires students to complete about 53 classes.
27 classes overlap between the two programs.

If a student wanted to double major in Math and Physics at St. Louis University, how many total math required and physics required classes would they have to take?

What is the probability that a random class that a double-major takes is ONLY needed for their math degree?

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!

one more happy customer!
