Answer:

20 ft

Step-by-step explanation:

We know that

Perimeter of rectangle = 2(l + w)

Let the width be w

=> 104 = 2(32 + w)

=> 104/2 = 32 + w

=> 52 = 32 + w

=> 52 - 32 = w

=> 20 = w

Hence z

Width of playground is 20 ft

Answer:

<h2>20</h2>

Basic fact:

<em>perimeter is (one side x by 2) + (the other side x by 2)</em>

Step-by-step explanation:

To find the other side we have been already given the total which is 104

We have also been given one side which is 32

we need to times 32 by 2 which is 64

subtract 64 from 104 which is 40

divide 40 by 2 which is 20

tigry1 [53]
It's 34.

You can either intuitively know 25% means one-fourth and divide 136 by 4

Or

Convert the percentage to a decimal and multiply. 136 * 0.25 = 34

A wheel has a diameter of 21 inches. <br><br> Approximately how far does it travel in 3 revolutions?
RideAnS [48]
So each 1 revolution it travels the distance around the rim of the wheele aka circumference
circumference=pi times diameter
diameter=21
circunference=pi times 21 or 21pi
so distance=number of revolutions times circunference
number of revolutions=3
subsitute

distance=3 times 21pi
distance=63pi

answer is 63pi
or aprox pi to 3.14 and do 63 times 3.14=197.82
aprox 197.82 inches

Find the volume of the given solid region in the first octant bounded by the plane 9z+15y+15z=45 and the coordinate​ planes, usi
dem82 [27]

First,

9x+15y+15z=45\implies 3x+5y+5z=15

The volume is given by the integral (one of 6 possible combinations),

\displaystyle\int_0^5\int_0^{\frac{15-3x}5}\int_0^{\frac{15-3x-5y}5}\mathrm dz\,\mathrm dy\,\mathrm dx=\boxed{\frac{15}2}

Given the measure of three angles in a quadrilateral, find the measure of the fourth angle.1. 40 degree , 120 degree , 100 degre
Veronika [31]

Recall that the interior angles of a quadrilateral add up to 360 degrees.

1) Let x be the measure of the missing angle, then we can set the following equation:

40^{\circ}+120^{\circ}+100^{\circ}+x=360^{\circ}.

Solving for x we get:

\begin{gathered} 260^{\circ}+x=360^{\circ}, \\ x=100^{\circ}\text{.} \end{gathered}

2) Let y be the measure of the missing angle, then we can set the following equation:

73^{\circ}+107^{\circ}+122^{\circ}+y=360^{\circ}\text{.}

Solving for y we get:

\begin{gathered} 302^{\circ}+y=360^{\circ}, \\ y=58^{\circ}\text{.} \end{gathered}

Answer:

1) 100 degrees.

2) 58 degrees.
