32:__=12:24
whats the answer

Answers

the answer would be 64 since the equation is 32:_=12:24, and 12:24 simplified would be 1:2, 32 times two would be equal to 64, making the ratio complete and correct.
Hope this helps
32: __ = 12 : 24

32 divided 3 = 12

so that means __ divide 3 should be 24

24 * 3 = 72

Plug it in:

32:72 = 12: 24

Does 32:72 simplify to 12:24? Yes, so it should be your answer... unless the question is asking for something else.

Find the mean of this set of numbers.5, –11, 7, 12, –1, 0

A.
2

B.
–2

C.
–6

D.
6

Answers

This is how you find the mean of a number:

To find the mean of a number, you need to add up all the numbers listed (so, 5, -11, 7, 12, -1 and 0) and then divide it by the amount of numbers there are listed. 5 + -11 + 7 + 12 + -1 + 0 equals 12, and since there are 6 numbers you then divide 12 by 6. 12 divided 6 is 2. 

So the answer is A. I hope this helped you!
The answer is 2

Jim drove the 120 miles to Grandmother's house in 3 hours. He increased his speed by10 miles per hour on the way home. How long did it take him to drive home?

Answers

Ok so basically you want for this specific problem to set up a proportion.  So 120 mi/3hours=x/10 miles. X is the unknown variable we are solving for so pay close attention. So now I am going to multiply 120 times 10 which is 1200 now that divided by 3 is 400. Hoped this helped !!!
Well if he drove there in 3 hour and went 120 miles then it would have took him 2 hours to get home

juan received a paycheck of $185 from his job he spend 1/4 of his paycheck on clothes and then spend $8.25 for Lunch how much of his paycheck did juan spend? someone HELP

Answers

He receives $185

He spent 1/4 of his paycheck on clothes, that is, = 1/4 *185 = 46.25

$8.25 for lunch.

Total spent =  8.25 + 46.25 = 54.50.

So he spent   $ 54.50 of his salary
1/4 = 46.25
lunch = 8.25
add them together 
50.50
Now take that away from 185 and that makes 
134.50
