The length of a rectangle is twice its width. The perimeter of the rectangle is 36 cm. Calculate the area of the rectangle

Pie

Length = 2(width)
perimeter = 36 cm

using variables where x = width and y = length

Perimeter = 2x + 2y = 36 cm
y = 2x

solving for length 2x + 2(2x) = 36 cm
   2x + 4x = 36 cm
   6x = 36 cm
   x = 6 cm

      so y = 2(6 cm) = 12 cm

area of rectangle = 12 cm * 6 cm = 72 cm^2

Last year, Keiko had $20,000 to invest. She invested some of it in an account that paid %7 simple interest per year, and she inv

erma4kov [3.2K]

Answer:

$P_2 = \$6,000\\P_1 = \$14,000$

Step-by-step explanation:

The formula of simple interest is:

$I = P_0rt$

Where I is the interest earned after t years

r is the interest rate

$P_0$ is the initial amount

We know that the investment was $20,000 in two accounts

_______________________________________________

<u><em>For the first account</em></u> r = 0.07 per year.

Then the formula is:

$I_1 = P_1r_1t$

Where

$P_1$ is the initial amount in account 1 at a rate $r_1$ during t = 1 year

$I_1 = P_1(0.07)(1)\\\\I_1 = 0.07P_1$

<u><em>For the second account </em></u>r = 0.05 per year.

Then the formula is:

$I_2 = P_2r_2t$

Where

$P_2$ is the initial amount in account 2 at a rate $r_2$ during t = 1 year

Then

$I_2 = P_2(0.05)(1)\\\\I_2 = 0.05P_2$

We know that the final profit was I $1,280.

So

$I = I_1 + I_2=1,280$

Substituting the values $I_1$ , $I_2$ and I we have:

$1,280 = 0.07P_1 + 0.05P_2$

As the total amount that was invested was $20,000 then

$P_0 = P_1 + P_2 = 20,000$

Then we multiply the second equation by -0.07 and add it to the first equation:

$0.07P_1 + 0.05P_2 = 1.280\\.\ \ \ \ \ \ \ \ +\\-0.07P_1 -0.07P_2 = -1400\\-------------$

$-0.02P_2 = -120\\\\P_2 = 6,000$

Then $P_1 = 14,000$

Answer:

1. Equation: $P=90N+2,100$

2. Total pay if Henry sells 27 copies: $4,530\$$

Step-by-step explanation:

1. The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

According to the information given in the exercise, his base salary is $2,100. So you can identify that:

$b=2,100$

Since he makes an additional of $90 for every copy of he sells, you can identify that:

$m=90$

Therefore, the equation that represents this situation is:

$P=90N+2,100$

2. If he sells 27 copies, then:

$N=27$

Substituting this value into the equation, you get that his total pay would be:

$P=90(27)+2,100\\\\P=4,530$
