That would be:-
x^2 + x - 72 = 0
(x + 9)(x - 8) = 0
smallest number is 8
Total investment = $10,500
Let x = amount of first investment, and y the amount of the second investment.
First investment:
Interest rate = 9 (1/5)% = 0.092
Earned interest = 0.092x
Second investment:
Interest rate = 9% = 0.09
Earned interest = 0.09y
Total interest after one year is $957.00, therefore
0.092x + 0.09y = 957
or
1.0222x + y = 10633.33 (1)
Also,
x + y = 10500 (2)
Subtract (2) from (1).
0.0222x = 133.33
x = 6000
y = 10500 - x = 4500
Answer:
The first investment is $6,000 at 9 (1/5)% rate;
The second investment is $4,500 at 9% rate.
Answer:
3 term
Step-by-step explanation:
Count the amount of numbers between operations
75 + 10 = 85
85 - 10 = 75
85 - 75 = 10
There is nothing to solve for.
The radius would be 8. The formula is 2πr. So 16 divided by 2 is 8. Therefore, the answer is 8.
