There is one third of a pie shared equally between 5 children. How much of the pie does each child receive? one ninth pie one fi

adoni [48]

Answer:

Each of the 5 children receive one fifteenth pie

Step-by-step explanation:

Given:

One third of a pie shared equally between 5 children.

To find:

Amount of the pie with each of the 5 children.

Solution:

Number of children = 5

Also, one third of a pie shared equally between 5 children.

So,

Amount of the pie with each of the 5 children $=\frac{\frac{1}{3} }{5}=$ $\frac{1}{15}$

Hence, each of the 5 children receive one fifteenth pie.

Change the width 20/16 inches to a mixed numeral in simplest form.

Iteru [2.4K]

Answer:1 and 1/4

Step-by-step explanation:

Okay, let's see the given: 20/16

So, we can take out 16 from the top to make it 1 4/16

Now, we can simplify that by dividing the top and bottom by 2: 1 2/8

We can simplify that again to get 1 1/4

So the answer is 1 and 1/4

What is the length of the arc if: 11. r=10 n=20 A15(pi)/ 7 B13(pi)/ 5 C16(pi)/ 2 D11(pi)/ 4 E 10(pi)/ 9 F 9(pi)/ 4 12. r=3 n=6 A

Vilka [71]

Step-by-step explanation:

The formula for arc length [for the angle in degrees] is:

$L = 2\pi r \left(\dfrac{n}{360}\right)$

here,

$n$ = degrees

$r$ = radius

using this we'll solve all the parts:

r = 10, n = 20:

$L = 2\pi r \left(\dfrac{n}{360}\right)$

$L = 2\pi (10) \left(\dfrac{20}{360}\right)$

from here, it is just simplification:

2 and 360 can be resolved: 360 divided by 2 = 180

$L = \pi (10) \left(\dfrac{20}{180}\right)$

10 and 180 can be resolved: 180 divided by 10 = 18

$L = \pi \left(\dfrac{20}{18}\right)$

finally, both 20 and 18 are multiples of 2 and can be resolved:

$L = \pi \left(\dfrac{10}{9}\right)$

$L = \dfrac{10\pi}{9}$ Option (E)

r=3, n=6:

$L = 2\pi r \left(\dfrac{n}{360}\right)$

$L = 2\pi (3) \left(\dfrac{6}{360}\right)$

$L = \dfrac{\pi}{10}$ Option (D)

r=4 n=7

$L = 2\pi r \left(\dfrac{n}{360}\right)$

$L = 2\pi (4) \left(\dfrac{7}{360}\right)$

$L = \dfrac{7\pi}{45}$ Option (C)

r=2 n=x

$L = 2\pi r \left(\dfrac{n}{360}\right)$

$L = 2\pi (2) \left(\dfrac{x}{360}\right)$

$L = \dfrac{x\pi}{90}$ Option (D)

r=y n=x

$L = 2\pi r \left(\dfrac{n}{360}\right)$

$L = 2\pi (y) \left(\dfrac{x}{360}\right)$

$L = \dfrac{xy\pi}{180}$ Option (E)
