Answer:C) 4 feet and 12 feet

Step-by-step explanation:

The diagram of the first mural is shown. The formula for determining the perimeter of a rectangle is expressed as

Perimeter of rectangle = 2(L + W)

The length of the first mural is given as 8ft while the width of the first mural is given as 6 ft. The perimeter becomes

P = 2(8 + 6) = 2×14 = 28ft

The area of a rectangle is expressed as L×W

The area if the first mural would be

6 × 8 = 48ft^2

The second mural has the same area as the first mural but has a different perimeter. The side lengths of the second mural are

4 ft and 12ft

Area = 4×12 = 48 ft^2

Perimeter = 2(12+4) = 32ft

So area is the same and perimeter is different.

Answer:

D. x=1

Step-by-step explanation:

Image can be rewritten as 3x + 6 = 9.

Solve for x.

3x +6 = 9

Isolate x by subtracting 6 from both sides.

3x = 3

Get rid of the 3 by dividing by 3 on both sides.

x = 1

Hope this helped.

Se cocina una pizza de 20 cm de radio, en su interior se coloca al azar 12 piezas de salami

Furkat [3]

Answer:

The area of cheese is 388π cm.

Step-by-step explanation:

Given that,

Radius of pizza = 20 cm

Number of pieces = 12

Radius of circle = 1 cm

We need to calculate the area of pizza

Using formula of area

$A=\pi\times r^2$

Put the value into the formula

$A=\pi\times20^2$

$A=400\pi\ cm^2$

We need to calculate the area of circle

Using formula of area

$A'=\pi\times r^2$

Put the value into the formula

$A'=\pi\times1^2$

$A'=\pi\ cm^2$

Now, we multiply the result by 12 because they are 12 salamis.

So. the area of salamis will be

$A'=12\pi\ cm^2$

We need to calculate the area of cheese

The total area of the pizza and subtract the area of the salamis

$A''=A-A'$

Put the value in to the formula

$A''=400\pi-12\pi$

$A=388\pi\ cm^2$

Hence, The area of cheese is 388π cm.

Iteru [2.4K]

Answer:

9 Quarters, 3 dimes

Step-by-step explanation:

$2.00 = 8 quarters

25cents = 1 quarter

2.55 - 2.25 = .30

30cents = 3 dimes.

Hope this is right.

There were many ways to do this. But this is 1 way.
