Answer:

Step-by-step explanation:

Remark

The measurement of the arc is 3Pi

that represents 108 / 360 of the circle.

Equation

108/350 2 * pi * R = 3* pi

Solution                            

Pi is on both sides of the equation. They both cancel.

108/360 = 0.3

0.3 * 2 * R = 3

0.6 * R = 3

R = 3/0.6

R = 5

ariane borrows $400 on a 4-year loan. she is charged 5% simple interest per year . How much interest is she charged for 4 years?
vodomira [7]

Answer:

  1. Interests charged for 4 years: $80
  2. Total amount to pay back:$480

Step-by-step explanation:

  • To know the future value of an specific amount that is borrowed from a  bank we use the following equation: FV= PV\imes{(1+n\times{i})}, where FV is future value, PV present value, n the amount of periods and i the interest rate.
  • In this particular case, the present value of the loan is $400, n=4 (4 years), i=5%. Then the future value equals: FV= 400\times(1+4\times0.05). Then FV= $480, which is the total amount of money she would have to return in 4 years.
  • The interest paid can be calculated as the total amount paid ($480) minus the inicial loan ($400), which means that total interests paid= FV- PV= $80.

Zana Lovley has a small craft
Maksim231197 [3]

Answer:

$619.56

Step-by-step explanation:

Think ALOE: Assets = Liabilities + Owner's Equity (capital)

Assets- anything of value you own (+)

Add 400.25, 612.84, 58.72, 468.22

400.25 + 612.84 + 58.72 + 468.22

= 1540.03 (this is Zana's total assets and owner's equity - both sides of the aloe equation have to stay equal)

Owing someone is a liability, therefore subtract 807.58 and 112.89 from your assets and owner's equity

1540.03 - 807.58 = 732.45

732.45 - 112.89 = $619.56

Zana's capital is $619.56

Have a lovely rest of your day! :)

I need some help with this rational equation. It's supposed to = -1, but for some strange reason I keep getting x^2 +2x = -1.
Rasek [7]

This one is so easy that your brain refuses to accept it.
It's looking for a harder answer, but can't find it !

You're totally correct, as far you went.     x² + 2x does = -1

Now add ' 1 ' to each side:     x² + 2x + 1 = 0

Can you factor that quadratic ?
Can you mash it through the quadratic formula ?

Actually, it's the simplest possible perfect square.

                                       x² + 2x + 1  =  (x + 1)²

So the solutions of     x² + 2x + 1 = 0  are both   x = -1 .

Don't say anything.
I know it's embarrassing.
