Jacob makes 20 baskets for every 35 times he shoots the ball. What is the ratio of baskets he makes to baskets he misses? Write
Kipish [7]

Answer:

ratio = 4/3 = 1.3333

Step-by-step explanation:

If Jacob makes 20 baskets for every 35 times he shoots the ball, that means he misses 35 - 20 = 15 shoots for every 35 shoots.

So, to calculate the ratio of baskets he makes to baskets he misses, we just need to divide these values:

baskets he makes = 20 for every 35

baskets he misses = 15 for every 35

ratio = 20 / 15 = 4 / 3 = 1.3333

A triangle has measurements of 39, 52, and 65 units. Is it a right triangle?
Ivanshal [37]
Hi!

We can use the Pythagorean Theorem to see if it is a right triangle.

The Pythagorean Theorem is a² + b² = c².

c = the longest side, or the hypotenuse. In this case, the hypotenuse should be 65.
39 can be a, and 52 could be b, or 52 could be a, and 39 could be b. It doesn't matter. 

39² + 52² = 65²

Is this equation true? 

Yes! This equation is true. 

The answer is Yes, this is a right triangle. 

Hope this helps! :)
