15/2 = 7.5 can per dat

7.5/7 = 1.1 = 1 can per man

1 x 4 = 4 cans per day

4 x 7 = 28

Final answer would be 28 if you round. If you don’t the answer would come out to be 30.8. Take your pick.

If 15 cans of food are needed for 7 men for 2 days, then 30 cans of food are needed for 4 men for 7 days. 

Assuming that the men eat every day, without skipping a day, then the first part of the sentence is basically saying 15 cans can feed 14 men. There are seven men who can survive off part of the 15 cans on day one, and seven men who can survive off of what's left of the 15 cans on day two.  The 15 cans have the potential to feed 14 men in one day basically. Applying this same theory, x number of cans has the potential to feed 28 (that's 4 men for 7 days). If these cans are the same size and are equal in terms of how filling its contents are, then we can set up a proportion.

15/14 = x/28
If 15 cans of food can feed 14 men, then x cans of food can feed 28 men.
Cross Multiply
14x = 420
Divide both sides by 14
x = 30

30 cans of food can feed 4 men for 7 days. Hope this helps!

CAN SOMEONE HELP ME WITH THIS PLEASE AND THANK YOU.
svp [43]

Answer:

13/20

Step-by-step explanation:

To add fractions without the common denominator, you have to make them equal so

1/4 x 5 = 5/20

2/5 x 4 = 8/20

5/20 + 8/20 = 13/20

Which of the following rational number between 3/7 and 7/8 ?
Charra [1.4K]

Answer:

Step-by-step explanation:

There are two ways to do this. You could use your calculator to find out the decimal numbers that are equivalent to the two given fractions. Then check which one of the givens falls between these two numbers. I wouldn't do it that way -- not when you are told that the answer has 56 as the denominator.  So ...

The best way to do it is to change the two givens so that they have a denominator of 56

3/7 = 3*8/7*8 = 24 / 56

7*7 / 7*8 = 49 / 46

So you need a number that is between 49 and 24

There is only one 27 / 56

How long does it take for a car traveling at a speed of 50.0 miles per hour to travel 300 feet?
beks73 [17]
We know, Time = distance / speed
t = 0.0568182 / 50  [ 300 Feet = 0.0568182 miles ]
t = 0.001136 * 3600 s
t = 4.09 sec

In short, Your Answer would be 4.09 Seconds

Hope this helps!
