Of the part, the whole, and the percent, which information is still unknown to Mr. Gregory? Find this unknown value.​

Answers

Answer 1
For ms Morgan it tells you 30% and 120 students so the thing you don’t know is the part.
30% of 120 is 36

For mr Gregory it tells you 27 is 15% so you don’t know the total amount of students he has (whole)
27 is 15% of 180
Answer 2

Answer:

A=30%

B=27

Find one pair of prime numbers whose product is an even number.

Answers

Answer:

I think it's 1 and two for example 2 times 7 is 14

Step-by-step explanation:

Answer:

2 and 3.

Step-by-step explanation:

To get a product of an even number, you have to either multiply two even numbers together or multiply an even number and an odd number together.

There is only one even prime number- 2.

Therefore, you can have any pair of prime numbers that, when multiplied together, get an even number as long as one of those numbers is 2.

2 and 3 work, as well as 2 and 5. The list goes on and on. Just choose a random prime number (that's not 2) and pair it with 2. It is guaranteed that when you multiply those two numbers together, you will get an even number.

The length of a room is 7.25 feet longer than the width, x, of the room. Which expression represents the perimeter of the room?

Answers

Answer:

P = 14.5+4x

Step-by-step explanation:

Let the width of the room is x.

Length = 7.25 feet longer than the width = 7.25 +x

We need to find an expression the represents the perimeter of the room.

Perimeter = sum of all sides

P = 2(l+b)

l is length and b is width

P = 2(7.25 +x+x)

=2(7.25 +2x)

=14.5+4x

Hence, the required expression for the perimeter is 14.5+4x.

The pizza shop down the street offers a special of a large pizza with 3 toppings. The choices of toppings

are pepperoni, sausage, ham, pineapple, cheese, onions, green peppers, hot peppers, mushrooms, and

anchovies.

How many ways can you arrange 3 toppings out of 10 toppings on a pizza?

Answers

Answer:

120 ways

Step-by-step explanation:

To solve this question, we would be using the law of combination.

In combination, we say that

nCr = n! / (n - r)! r!, where both r and n are integers.

Now, referring to question, we are asked how many ways we can arrange 3 toppings out of 10. This means we're looking for 10C3. Applying the earlier laid out formula, we have

10C3 = 10! / (10 - 3)! 3!

10C3 = 10! / 7! 3!

10C3 = 3628800 / 5040 * 6

10C3 = 3628800 / 30240

10C3 = 120

Therefore, the toppings can be arranged in 120 ways.

what's the ratio for 3 stars and 7 circles

Answers

Answer: 3:7

Step-by-step explanation:

There are 3 stars for every 7 circles, thus the ratio is 3:7.

Answer:

3 : 7.

Step-by-step explanation:

For every 3 stars, there are 7 circles. If 3 stars is written first, you'll need to write 3 first in your answer, and 7 second.

This is what it would look like: 3 : 7

With ratios, you could also write,

3 to 7

or

3 / 7
