Answer:
A. 48mi^3
Step-by-step explanation:
To find the volume of a rectangular prism, you multiply:
length x width x height
Answer:
0.75
the reason is because if we round it to the nearest tenth . 0.75 becomes 0.8. and 0.075 becomes 0.1 . 0.8 is 8/10th of 1. 0.1 is 1/10th of 1. therefor 0.8 is bigger
In order to find the number times something is larger than something, you have to use division where you divide the larger number by the smaller number.
So:

I'm not sure how much you want to round to, but the answer is 387.6063183 times.
You can make sure by multiplying the smaller number by 387.6063183 and you should get the larger number:

Let the amount invested at 4% be = x
Let the amount invested at 3% be = y
Given is:
or
.... (1)
As, total income for the two investments is $194, so equation is:
....(2)
Putting value of x from (1) in (2)




And x=5200-y

Hence, money invested at 4% is $3800 and money invested at 3% is $1400
