R = 8.5%/year

Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving our equation
r = (1/2)((20475/17500) - 1) = 0.085
r = 0.085
converting r decimal to a percentage
R = 0.085 * 100 = 8.5%/year

The interest rate required to get
a total amount, principal plus interest, of $ 20,475.00
from simple interest on a principal of $ 17,500.00
over 2 years is 8.5% per year.

Please help!!!
ki77a [65]

Answer:

312

Step-by-step explanation:

First we need to determine the width

A = l*w

6.2 * 10 ^3 = 1.55 * 10 ^2 * w

Divide each side by 1.55 * 10 ^2

6.2 ^ 10 ^3  /1.55 * 10 ^2 = 1.55 * 10 ^2 * w / 1.55 * 10 ^2

Changing from scientific notation to standard

6200/155 = w

40 = w

Then we need to determine the perimeter

P = 2(l+w)

P = 2( 155+40)

P =2( 195)

P = 390

Now multiply by the price

390 *.80

a crew is made up of 14 men; the rest are women. 66 2/3% of the crew are men. how many people are in the crew?
Westkost [7]

There are 21 people in the crew.

Step-by-step explanation:

Given,

Number of men in the crew = 14

Percent of men = 66\frac{2}{3}=\frac{200}{3}%

Let,

x be the number of people in crew.

According to given statement;

\frac{200}{3}\% \ of\ x=14\\\\\frac{200}{3*100}x=14\\\\\frac{200}{300}x=14

Multiplying both sides by \frac{300}{200}

\frac{300}{200}*\frac{200}{300}x=14*\frac{300}{200}\\x=7*\frac{300}{100}\\x=7*3\\x=21

There are 21 people in the crew.
