Answer:
$103,373.81
Step-by-step explanation:
The calculation of the future value is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
where,
rate of interest = 11.25% ÷ 2 = 5.625%
And, the number of years is = 2 × 10 = 20
Therefore, the future value is
= $34,600 × (1 + 5.625%)^20
= $34,600 × 2.987682472
= $103,373.81
The answer should be 42.
Since there are 60 questions in the test and she managed to answer 70% of the questions correctly, that means that she answered 70% out of 60 questions correctly.
So you need to calculate how much 70% out of 60 is. Since % is always measured on a base from 0 (%) to 100(%), then 70% is equal to the fraction 70/100, simplified to 7/10. To know how much 7/10 out of 60 is,you just multiplie them and your answer will be 42.
I hope this helps you forward.

Answer:
(x, y) = (1, 1/3)
Step-by-step explanation:
The x-coefficient in the first equation is -2 times that in the second equation, so adding twice the second equation to the first will eliminate x:
(4x -9y) +2(-2x +3y) = (1) +2(-1)
-3y = -1 . . . . simplify
y = 1/3 . . . . . divide by -3
The y-coefficient in the first equation is -3 times the y-coefficient in the second equation, so adding 3 times the second equation to the first will eliminate y:
(4x -9y) +3(-2x +3y) = (1) +3(-1)
-2x = -2 . . . . . . simplify
x = 1 . . . . . . . . . divide by -3
The solution is (x, y) = (1, 1/3).
