Answer:

1.)

132 cm - 11 cm = 121 cm

So let the hypotenuse be x and the other leg be (121 - x).

11^2 + (121 - x)^2 = x^2

121 + 121^2 - 121(2)x = 0

x = 1/2 + 121/2 = 61 cm

Step-by-step explanation: not sure if this is right or not

What is the present value of ​$3,000 per year for 9 years discounted back to the present at 10 ​percent?
Studentka2010 [4]

Answer:

$17,277.07

Step-by-step explanation:

Present value of annuity is the present worth of cash flow that is to be received in the future, if future value is known, rate of interest is r and time is n then PV of annuity is

PV of annuity = \frac{P[1-(1+r)^{-n}]}{r}

                      = \frac{3000[1-(1+0.10)^{-9}]}{0.10}

                      = \frac{3000[1-(1.10)^{-9}]}{0.10}

                      = \frac{3000[1-0.4240976184]}{0.10}

                      = \frac{3000(0.5759023816)}{0.10}

                      = \frac{1,727.7071448}{0.10}

                      = 17,277.071448 ≈ $17,277.07

Vlada [557]

Answer:

Cole spend 47.587 on buying gifts for each person.

Step-by-step explanation:

Given:

Total money spend on gifts = 523.46

Hence Cole spend 47.587 on buying gifts for each person.
