Answer:

1. 10 miles

2. 12 feet

Step-by-step explanation:

For question 1, they both walk for two hours so Sara walked 8 hours and her sister walked 6 miles. Since they went 90˚ opposite directions, we have to use the Pythagorean Theorem to find the distance. 8 squared plus 6 squared equals c squared. 64 plus 36 equals c squared. The square root of 100 is 10, so the distance is 10 miles.

For question 2, you also have to do the Pythagorean Theorem. So, since the hypotenuse is 15, we do 15 squared minus 9 squared equals b squared. 225 minus 81 equals b squared. 144 equals b squared. The square root of 144 is 12. The answer is 12 feet. I hope this helped and please mark me brainliest. I spent I lot of time on this!

April is randomly choosing five CDs to bring in her car from the following: 6 pop CDs, 8 rock CDs, and 10 R
Ymorist [56]

The complement of "April choosing five Pop CDs" is "Choosing five CDs where not all of them are Pop", making the second option a right choice.

In the question, we are given that April is randomly choosing five CDs to bring in her car from the following: 6 Pop CDs, 8 Rock CDs, and 10 R&B CDs.

We are asked what will be the complement of April choosing 5 Pop CDs.

The complement of a set is the one, where no element of the original set is present.

The original set is that "April is choosing 5 Pop CDs".

This means that April, while choosing 5 CDs from the given set, chooses all 5 CDs to be Pop.

While making the complement we need to change the final outcome.

To change this, we just need to make one exception to this, which can be achieved by making one other than Pop CD.

This gives us the set: "Choosing 5 CDs where not all of them are complement".

Thus, the complement of "April choosing five Pop CDs" is "Choosing five CDs where not all of them are Pop", making the second option a right choice.
