Answer:

The deep of the sand will be 3.5 feet

Step-by-step explanation:

step 1

Find out the area of the court plus a 10-foot boundary around the court for safety

$A=(30+10+10)(60+10+10)\\A=(50)(80)\\A=4,000\ ft^2$

step 2

Find the deep of the sand

we know that

The volume of the sand is equal to

$V=Ah$

where

A is the area of the base

h is the height or deep of the sand

substitute the given values

$14,000=(4,000)h$

Solve for h

$h=14,000/4,000=3.5\ ft$

1.)A rectangle has an area of 72 square centimeters and the length is twice the width. The perimeter of the rectangle

Greeley [361]

area = L x w = 72

L = 2w

72 = 2w*w = 2w^2

divide by 2

36 = w^2

w = sqrt(36) = 6

l = 2*6 =12

perimeter = 2L +2W = 2*12 + 2*6 = 24+12 = 36

sqrt(40)= 6.324555 cm ( round to 6.32 )

6.32 - 4 = 2.32 cm original length of a side

In 15 minutes, Jada would have covered about 2.5 miles, while the cousin would have covered 0.625 miles.

<h3>What is speed?</h3>

Speed is the ratio of distance to time.

For Jada:

Speed = 2 miles / 12 minutes = 0.167 miles per minute

For Jada cousin:

Speed = 1 mile / 24 min = 0.0417 miles per minute.

Hence, in 15 minutes:

Jada distance = 15 min * 0.167 miles per minute = 2.5 miles

Jada cousin distance = 15 min * 0.167 miles per minute = 0.625 miles

In 15 minutes, Jada would have covered about 2.5 miles, while the cousin would have covered 0.625 miles.

The figure below is a scale drawing of Quinto's bedroom. The scale used to create the drawing is 1/2 inch = 4 feet. What is the

Nezavi [6.7K]

We know that

the scale is <span>is 1/2 inch = 4 feet

using a graph tool
</span><span>the approximate measurements in the drawing are
</span>5 cm x 4 cm
convert to in
5/2.54--------> 1.97 in
4/2.54------> 1.57 in

convert drawing to actual
if 0.5 in---------> 4 ft
1.97in-------> X
X=1.97*4/0.5------> X=15.76 ft

if 0.5 in---------> 4 ft
1.57 in-------> X
X=1.57*4/0.5------> X=12.56 ft

<span>the approximate area of Quinto's bedroom is 12.56*15.76=197.95 ft</span>²

the answer is
