Step-by-step explanation:

$\frac{1}{100} = \frac{1}{ {10}^{2} } = {10}^{ - 2} \\ \\ reason \\ \: \because \: \frac{1}{ {a}^{2} } = {a}^{ - 2} \\ \\ \implies \: \frac{1}{ {10}^{2} } = {10}^{ - 2}$

A right rectangular prism has a length of 8 centimeters, a width of 3 centimeters, and a height of 5 centimeters. What is the su

ladessa [460]

Answer: $158cm^2$

Step-by-step explanation:

You can use the following formula to calculate the surface area of the right rectangular prism:

$SA = 2(wl +lh + hw)$

Where "w" is the width, "l" is the length, and "h" is the height.

Knowing that this rigth rectangular prism has a length of 8 centimeters, a width of 3 centimeters and a height of 5 centimeters, you can substitute these values into the formula.

Then, the surface of the right rectangular prism is:

$SA = 2[(3cm*8cm) + (8cm*5cm) + (5cm*3cm)]\\\\SA=158cm^2$

(If one square on the graph = one centimeter)

b = 10cm

b = 10cmh = 10cm

Area:

$= \frac{1}{2} \times b \times \: h$

$= \frac{1}{2 } \times 10 \times 10$

$= \frac{1}{2} \times 100$

$= 50 {cm}^{2}$

Solve the system of linear equations. 3x−2y=1 9x−6y=3

irakobra [83]

Get the y by itself

-2y= -3x + 1

Divide -2 to everything

y= 3/2x - 1/2

Other equation (get y by itself)

-6y= -9x + 3
y=3/2x - 1/2

Use substitution

3/2x-1/2=3/2-1/2

0=0

All real numbers (any value of x makes the equation true)
