You need a common denominator in order to add/subtract fractions. for example:

1/4+3/2=?
1/4+6/4=7/4

what i did there was multiply 3/2 by 2/2 to get the denominator to equal 4. the reason it’s 2/2 is cause what you do to the bottom is what you do to the top.

3/2(2/2)= 6/4

Answer:

  • 615.8 square feet
  • 9 truckloads

Step-by-step explanation:

The area of the circular ring is given by the formula ...

  A = πr²

where r is the radius, or half the diameter.

  A = π(14 ft)² = 196π ft² ≈ 615.752 ft²

The area of the training area is about 615.8 square feet.

__

The number of truckloads of dirt required for coverage will be ...

  (615.8 ft²)/(75 ft²/truckload) ≈ 8.21 truckloads

Since the dirt comes only in whole truckloads, Hilary needs 9 truckloads.

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.
