What is the common denominator for 1/5 2/3 5/8?

SpyIntel [72]

To find the common denominator first find a number that goes into all the denominators;
the LCM of 5, 3, 8 = 120
so your new fractions with the same denominator are;
24/120, 80/120, 75/120

The length of a rectangle is twice its width. The Perimeter is 42 cm. Find the length of each side.

lakkis [162]

Answer:

A) L = 2*W

B) 2L + 2W = 42

We'll put Equation A) into B)

2*2W + 2W = 42

4W + 2W = 42

6W = 42 cm

Width = 7 cm

Length = 14 cm

Can someone help me with this problem?????

snow_tiger [21]

The perimeter is composed of two straight parts and two semicircles. We can use this to break down the problem.

We can find the straight parts easily. They are given in the problem.

straight parts: 82 x 2 = 164 m

The two semicircles make a circle. We just have to find the circumference of a circle with a diameter of 66 cm to get the length of the semicircles.

semicircles: 2(π)(66/2) = 66(3.14) = 207.24 m

answer: 164+207.24 = 371.24 m

Katen [24]

Answer:

The area of the wall that she will paint in two rolls is <u>219.8 inches²</u>.

Step-by-step explanation:

Given:

Jenny uses a roller to paint a wall. The roller has a radius of 1.75 inches and a height of 10 inches.

Now, to find the area of the wall that she will paint in two rolls.

So, we find the lateral surface area of roller.

Radius (r) = 1.75 inches.

Height (h) = 10 inches.

So, to get the lateral surface area we put formula:

$A_{L} =2\pi rh$

$A_L=2\times 3.14\times 1.75\times 10$

$A_L=109.9\ inches^2.$

Thus, the lateral surface area of the roller = 109.9 inches².

Now, to get the area of wall that she will paint in two rolls we multiply 2 by the lateral surface area of the roller:

$109.9\times 2\\\\=219.8\ inches^2.$

Therefore, the area of the wall that she will paint in two rolls is 219.8 inches².
