Answer:
The total interest earned at the end of the year was $ 820, and the interest generated by the total deposited was 10.25%.
Step-by-step explanation:
Given that last year, Manuel deposited $ 7000 into an account that paid 11% interest per year and $ 1000 into an account that paid 5% interest per year, and no withdrawals were made from the accounts, to determine what was the total interest earned at the end of year and what was the percent interest for the total deposited, the following calculations must be performed:
7000 x 0.11 + 1000 x 0.05 = X
770 + 50 = X
820 = X
8000 = 100
820 = X
820 x 100/8000 = X
82,000 / 8,000 = X
10.25 = X
Therefore, the total interest earned at the end of the year was $ 820, and the interest generated by the total deposited was 10.25%.
Answer:
The value of x is 11.
Explanation:
The opposite sides of a parallelogram being equal, GD will be equal to 17. Equating, the value '11' is obtained.
30% of number A means

similarly, 40% of number B means

These must be equal, so we have

Multiply both sides by 10 to get

So, you can choose any number for A, and then you multiply it by 4/3 to get B. There are infinitely many solutions to this equation.
OK.... here we go....
The width is 8 less than the length, so that means: w = L - 8.
So, since the area of a rectangle is: A = L x W ...
Therefore, 48 = L(L - 8)...
48 = L^2 - 8L...
continuing from there .... you get width = 4 and length = 12
48 = 4 x 12 (and notice that the width is 8 less than the length)
