Answer:

50 total penguins

Step-by-step explanation:

In the following example x = the total number of penguins.

Set it up as follows.

15 over x = 30 over 100

Cross multiply the numbers. (30 times x) and (15 times 100)

This results in 30x = 1500.

Divide both sides by 30 which results in x = 50.

This means that there is a total of 50 penguins.

In the following example x = the number of Emperor penguins.

If you would like to double check this, set up as follows.

x over 50 = 30 over 100

Cross multiply the numbers. (30 times 50) (100 times x)

This results in 100x = 1500.

Divide both sides by 100 which results in x =1 5.

This means that there are 15 Emperor penguins.

While traveling to his grandma for his George fell asleep a fifth of the way through the journey when he awoke he still had to t
jeyben [28]

Answer:

<u>George fell asleep when he had traveled 1/5 of the total distance, slept 3/5 of the distance and he awoke up when he's still 1/5 away from his grandma</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

George fell asleep a fifth of the way

He awoke up when he still had to travel a quarter of the distance that he had traveled while sleeping

2. For what part of the journey had he been asleep?

George fell asleep a fifth of the way: 1/5 of the total distance traveled and 4/5 of the distance away from his grandma

When he awoke up = 1/4 * 4/5 = 1/5

He had been asleep = 5/5 - 1/5 -1/5 = 3/5

<u>It means George fell asleep when he had traveled 1/5 of the total distance, slept 3/5 of the distance and he awoke up when he's still 1/5 away from his grandma</u>

Kathleen correctly determines four arithmetic means between −7 and 14. What values does Kathleen determine?
Annette [7]

Answer:

  Kathleen determines the four arithmetic means to be −2.8 , 1.4, 5.6, and 9.8.

Step-by-step explanation:

The overall interval is 14 -(-7) = 21 units in length. The four equally-spaced "means" divide the interval into 5 equal parts, each one of which is ...

  21/5 = 4.2

The four means are ...

  -7 +4.2 = -2.8

  -2.8 +4.2 = 1.4

  1.4 +4.2 = 5.6

  5.6 +4.2 = 9.8

4 divided by 457. Please list the steps
exis [7]
You find out how many times 4 goes into 4 and get 1 then you find out how many times 4 goes into 5 and get 1 but you subtract 5 minus 4 and get 1 then bring down the 7 to get 17 then find out how many times 4 goes into 17 which is 4 times because 4 times 4 is 16 and you do 17 minus 16 and get 1 then add a decimal and bring down the 1 to get 10 then find out how many times 4 goes into 10 and get 2 subtract and get 2 bring down the zero turn it into 0 then you get 20 then find out how many times 4 goes into 20 and get 5 and 4*5=20 so 20-20 is 0 so your answer is 114.25
