Answer:
404%
Step-by-step explanation:
To find the percentage difference do the following: (FV - SV)/|SV| * 100
(1260 - 250)/|250| * 100 <em>{Subtract 250 from 1260 to get 1010. The absolute value of 250 is 250.}</em>
1010/250 * 100 <em>{Divide 1010 by 250 to get 4.04, or 101/25.}</em>
101/25 * 100/1 <em>{CROSS CANCELLATION}</em>
101 * 4 <em>{Multiply 4 by 101 to get 404.}</em>
404%
The percent increase in the amount required to earn a credit over 38 years is 404%.
The answer to the problem is- 30, 1.5
Answer:
9 ft
Step-by-step explanation:
Let x represent the shortest piece. Then the sum of lengths is ...
x + (x +25) +3x = 40
5x = 15
x = 3
3x = 9
The third piece is 9 feet long.
_____
<em>Check</em>
The pieces are 3 ft, 28 ft, 9 ft, so total 40 ft, as required.
Answer:
a = -bc
Step-by-step explanation:
We are given the equation:
c = -a/b
Because multiplication and division are inverse operations, if we move b over to the other side, since it was dividing on the right side, it would be multiplied on the other side (I don't know how to explain that well)
so you can make it look like this:
b*c = -a
Or:
-a = b*c
Then, do isolate a, we will have to divide by -1 on both sides
a = -b*c
To check this, we can plug in numbers
-8 = -16/2
-16 = -8*2
16 = 8 * 2
