Answer:
12
Step-by-step explanation:
39/13=3
3 times 4 = 12
The ratio is 4:7 because since the ratio is red apples to green apples theirs 4 red apples and theirs 7 green
Answer:
54.48
Step-by-step explanation:
Answer: Choice B
12.5 < x < 18.9
================================================
Explanation:
We have a triangle with these side lengths:
- a = 10
- b = 16
- c = x = unknown
Let's assume that b = 16 is the largest side of this triangle.
By the converse of the pythagorean theorem, we need
to be true in order for an acute triangle to happen.
So,

Now let's consider the possibility that the missing side x is actually the longest side.
Using the same theorem as before, we would say,

We found that x > 12.5 and x < 18.9
This is the same as saying 12.5 < x and x < 18.9
Put together, they form the approximate answer of 12.5 < x < 18.9
