Answer:
56
Step-by-step explanation:
The ratio is 5 to 2, and we must keep it this way.
For example, if he had 10 regular sodas then the ratio would be 10:4.
If something happens to one side of this ratio, it needs to happen to the other so it remains balanced.
We need to find out how 5 got to 140. To find out, simply divide 140 by 5.
140 divided by 5 = 28
So, 5 was multiplied by 28 to get to 140.
Now, we need to multiply the 2 by 28 as well so it remains balanced.
2 x 28 = 56.
So, there are 56 diet sodas.
Answer:
Step-by-step explanation:
Volume of cylinder = πr2h
height =6 inches
r is the radius of the cylindrical container
48 in3 =πr2 * 6
6= πr2
π= 22/7
6*7/22=r2
42/22 =r2
21/11=r2
r2= 21/11
r = SQRT(21/11)
r= 1.38169855942
Answer:
$ 312.17
Step-by-step explanation:
We have to want to save an emergency fund based on household expenses, the first thing is to calculate how much to save those 4 months would be:
702.38 * 4 = 2809.52
In other words, you will need $ 2809.52 to save for 4 months
Now we must divide by 9 because that is the number of months it will take to save, therefore:
2809.52 / 9 = 312.17
That is to say, $ 312.17 per month, for 9 months to save 4 months of expenses.
