To do this, we need to know how much older than her daughter Sharon. She is 30 years older, so we get
d = s - 30
We want to figure out when d = s - 30, and 4d = s, so here's what we do:
Since 4d = s, we can substitute 4d for all occurences of s
d = 4d - 30
And then we can solve for d
-3d=-30
d=10
And then we plug that number into our original equation
10 = s-30
40 = s
Sharon was 40 years old when she was 4 times her daughter's age. Since she is now 42, we know she was 4 times her daughter's age 2 years ago

Madeline invested $51,000 in an account paying interest rate of 6 1/8% compounded daily. Harper invested 51000 in an account pay
LenaWriter [7]

Answer:

$5564.87

Step-by-step explanation:

We are to determine the difference between the future values of each investment

The formula for calculating future value:

FV = P (1 + r)^mn

FV = Future value  

P = Present value  

R = interest rate  

N = number of years

m = number of compounding

Madeline

P = Present value = 51,000

R = interest rate = 0.06125 / 365 = 0.000168

N = number of years = 13

m = number of compounding = 365

51,000 x (1.000168)^4745  = 113,070.20

Harper

51,000 x (1.004792)^156 = 107,505.33

Difference = 113,070.20 - 107,505.33 = $5,564.87

Solnce55 [7]

Answer:

  • A. (x^{2/7})(y^{-3/5})

Step-by-step explanation:

<u>The numerator is:</u>

  • \sqrt[7]{x^2}  = (x^2)^{1/7} = x^{2/7}\\

<u>The denominator is:</u>

  • \sqrt[5]{y^3}  = (y^3)^{1/5} = y^{3/5}

<u>The fraction is equivalent to:</u>

  • \frac{x^{2/7}}{y^{3/5}} =
  • (x^{2/7})(y^{-3/5})

Correct choice is A
