8. Sam divided a rectangle into 8 congruent
S_A_V [24]

Sam divided a rectangle into 8 congruent rectangles that each have a area of 5 cm2. what is the area of the rectangle before it is divided?

Answer:

Area\ of\ the\ rectangle = 40\ cm^{2}

Step-by-step explanation:

Given:

Sam divided a rectangle into 8 congruent  rectangles that each have an area of 5\ cm^{2}

We need to find the area of the rectangle before Sam divided it.

The area of the rectangle before Sam divided is 8 times of the area of the congruent rectangles.

Area of the rectangle = 8\times (area\ of\ congruent\ rectangles)

Area of the congruent rectangle is 5\ cm^{2}

So the area of the rectangle is

Area of the rectangle = 8\times 5

Area of the rectangle = 40\ cm^{2}

Therefore the area of the rectangle before divided is 40\ cm^{2}

A person's hourly pay rate, r, is found by dividing the total amount
marishachu [46]

Translating the words into formula, we have

r = \dfrac{p}{w}

In fact, we have that the pay rate is the total payment divided by the number of hours worked.

We can solve this formula for w in two steps: starting from the formula above, multiply both sides by w:

rw = p

And then divide both sides by r:

w = \dfrac{p}{r}

Calvin has $8.80 in pennies and nickels. If there are twice as many nickels as pennies, how many pennies does Calvin have? How m
Ray Of Light [21]

Let X = the number of pennies.

The number of nickels would be 2X

A penny is 0.01 and a nickel is 0.05

Now you have:

0.01x + 2(0.05x) = 8.80

Simplify:

0.01x + 0.10x = 8.80

Combine like terms:

0.11x = 8.80

Divide both sides by 0.11:

x = 8.80 / 0.11

x = 80

Pennies = X = 80 total pennies.

Nickels = 2x = 2 *80 = 160 nickels.
