Answer:
3.5 years
Step-by-step explanation:
Each year, Louis earned
$1500×0.035 = $52.50
in interest.
The amount of interest that had been credited to his account at the time of withdrawal was ...
$1683.75 -1500.00 = $183.75
Then the length of time the money had been in the account was ...
$183.75/($52.50/yr) = 3.5 yr
_____
<em>Comment on the problem</em>
We have assumed the account earned simple interest. Given the neatness of the answer, we believe that to be a correct assumption.
Well, first, we must subtract-2 by 1, as the negative sign next to 1 is inside the parentheses.
Now remember, since it is an absolute value, meaning the distance from that number to zero, we will now disregard the negative sign and get our answer: 3
Answer:
The wax will fill the mold a bit more than halfway.
Step-by-step explanation:
The volume of a sphere with radius is:
.
The radius of this sphere of wax is ; Its volume would be:
.
Assume that the wax here does not evaporate, combust, or otherwise disappear. .
The volume of a rectangular prism is equal to .
For this mold with a rectangular prism shape:
.
Half of that would be:
.
Compare these two volumes to the volume of wax available:
.
In other words, the wax will fill the mold a bit more than halfway, but not completely.
Answer:
The four pieces cut off can be arranged into two squares with sides of length b feet and hence the area of the octagon is w 2 - 2 b 2 square feet. Since w = 12 feet, all that is needed is to find b. square feet which is approximately 119 square feet.
