Answer: She invested $34100 at 10% and $68200 at 6%.
Steps:
Let x1 be the amount invested at 6%, x2 the amount at 10%
After one year the simple interest is amount * (interest rate).
The total interest after one year:
7502 = x1 * 0.06 + x2 * 0.10
and we know that x1 = 2*x2
7502 = 2* x2 * 0.06 + x2 * 0.10 = 0.22 * x2
x2 = 34100
x1 = 2*34100=68200
The numbers that satisfy the equation "What times what equals 31?" are 1 and 31.
We have,
To find two numbers that multiply to equal 31, we need to consider all the possible factor pairs of 31.
A factorpair is a pair of numbers that, when multiplied together, give the desired number.
In the case of 31, since it is a prime number, it only has two factors:
1 and 31.
Any other number would not evenly divide into 31 without a remainder.
So, the only pair of numbers that multiply to equal 31 is 1 and 31:
1 x 31 = 31
Therefore,
The numbers that satisfy the equation "What times what equals 31?" are 1 and 31.

what is the area of a circle if its radius is 3596cm let pi=3.14
Answer:
Step-by-step explanation:
What you are asking is to fill in the blank in the following sentence.
_______ % off this imported futon.
Solution
500 x/100 = 425 Divide the left by 100
5x = 425 Divide both sides by 5
5x/5 = 425/5 Simplify
x = 85
That is not the answer. That is the % paid.
The reduction is 100% - 85% = 15%
So your blank would contain 15%
Check
15% of 500 = 15/100 * 500 = 75 which is what they the store is offering you off.
