Answer:

<h2>231in^3</h2>

Step-by-step explanation:

We know that the volume of a sphere/globe is given as

V=4 /3πr^3

but the circumference is expressed as

C=2πr

solving for r given  that C=24

24=2*3.142r

24=6.284r

r=24/6.284

r=3.8in

put r=3.6 in the expression for volume we have

V=4 /3π(3.8)^3

V=4 /3π(55

V=(220.59*3.142)/3

V=693.12/3

V=231in^3

The volume of the globe is 231in^3

A water trough is 9 m long and has a cross-section in the shape of an isosceles trapezoid that is 20 cm wide at the bottom, 70 c
ella [17]

Answer:

dv = surface area * dh

so

dv/dt = surface area * dh/dt

width at surface = 40 + (80-40)(30/40)

= 40 + 30 = 70 cm = 0.70 m

so

surface area = 9 * .7 = 6.3 m^2

so

.3 m^3/min = 6.3 m^2 * dh/dt

and

dh/dt = .047 meters/min or 4.7 cm/min

The perimeter of a rectangular garden used 86 feet of barbed wire. The length of the garden is 7 feet more than its width. Find
Taya2010 [7]

Answer:

Step-by-step explanation:

perimeter of a rectangle  = twice the length  plus  twice the width

P = 2L + 2W    equation 1      P = 86 ft

Given the length is seven feet more than the width

L = W + 7         equation 2

Substitute equation 2 into equation 1

P = 2(W+7) + 2W    =  86 ft

     2W +14 + 2W    =  86 ft

     4W    =  86  - 14

        W   =  72 / 4

        W   =  18 feet

7. The amount of memory on a CD determines how many songs I can download to it.<br> Indep.<br> Dep.
galina1969 [7]

\bf \underset{dependent}{\stackrel{\textit{songs I can download}}{S(M)}}~~=~~\underset{independent}{\stackrel{\textit{how much memory I have}}{M}}

the memory is the independent, because that can vary at will, so it's independently varying at will, whilst the amount of songs are limited to how much memory there's in the CD, so the songs are dependent on the memory availability.

Diego's family spends $87 on 4 tickets to the fair and a $39 dinner.
svlad2 [7]

Answer: b. Lin buys a pack of 87 pencils. She gives 39 to her teacher and shared the remaining pencils between herself and 3 friends.

Step-by-step explanation:

Lin buys 87 pencils which is why the entire number line adds up to 87.

She gave 39 of these pencils to her teacher which s why there is a section of the number line that is unlike the rest and is 39 in number.

The rest of the number line is a set of 4 spaces which are equal.

Lin shared the remaining pencils between herself and 3 friends which means she shared the pencils with 4 people. These four equal quantities of pencils are the 4 spaces.
