Answer: 13
Step-by-step explanation:
If you remember the quadratic equation formula;

You can easily extract what is under the root to find the discriminant.

a = 3
b = 7
c = 3

3x4=12 gives him 12 baseballs. he has 5 fewer tennis balls than base balls so you subtract 5 from 12 and you get 7 tennis balls.
Answer:
A. 40
Step-by-step explanation:
Q1 - 40
Q2 - 65
Q3 - 80
And 90 is max
So 40 is the correct answer.
1:16 or 5:80, if you're simplifying then all you do is divide denominator by numerator. then that's your simplified ratio
Let's represent h with the number of hours:
15h ≥ 200
h ≥ 200/15
h ≥ 40/3
h ≥ 13 1/3
He has to work at least 13 1/3 hours.
