What is the largest number that divides into 20, 35, 40?

Answer: V = 1731.8Ft³

Step-by-step explanation:

v = πr²h

Radius is half of the diameter ⇒ 21/2 = 10.5

V = π(10.5)²(5)

V=π(110.5)(5)

V = π(551.25)

V = 1731.8Ft³

The solution is : the volume of the pool is V = 1731.8Ft³.

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

Here, we have,

we know that,

the volume of the cylinder is:

v = πr²h

Radius is half of the diameter

⇒ 21/2

= 10.5

so, we get,

V = π(10.5)²(5)

V=π(110.5)(5)

V = π(551.25)

V = 1731.8Ft³

Hence, The solution is : the volume of the pool is V = 1731.8Ft³.

Remark

I suppose the question is what is Thaddeus' time to make the trip. This is a fairly common question but not everyone knows how to solve it.

Derivation of the Formula

Prescott + Thaddeus = 1 trip

So the logic of the equation is this.

distance = 1 trip

time = number of dates

rate = ?

rate = distance / time

To find out what the contribution of Thaddeus is set up  a distance time formula.

1/21 days is the rate for Prescott

1/x days is the rate for Thaddeus

Together the rate is 1/9

Solution

1/21 + 1/x = 1/9

Subtract 1/21  from both sides

1/x = 1/9 - 1/21

It's not obvious what the LCM is.

9 = 3 * 3

21 = 3 * 7

LCM: 7 * 3 *3 = 63

1/x = 7/63 - 3/63 = 4/63

1/x = 4/63                             Cross Multiply

4x = 63                                 Divide by 4

x = 63/4

Answer

x = 15 3/4

x = 15.75

Step-by-step explanation:

Someone calculated his or her average speed to 18.36 Miles per hour (mph) Calculate your average speed This calculation will help you calculate your average speed when you have covered a certain distance over a certain time.

Answer:

2 mph

Step-by-step explanation:

if we divide our miles by our time with the equation d for distance and t for time we'll get this

d/t = s (s to represent the speed

now time to plug in our equation

25/12.5 = 2

we now have our answer of 2 miles per hour

51. Don't completely know if it's correct though.

Step-by-step explanation:

I'd use sine, which is opposite side/hypotenuse. Here, I think the reference angle is x. The opposite side is 7, and the hypotenuse is 9. So...

sin(x) = [tex]\frac{7}{9}[/tex]

sin(x) = 0.7777

Next we use inverse sine.

sin⁻¹(0.7777) = approximately 51

The value of the angle x, for the given right angle, is approximately 51 degree to the nearest degree.

In a right angle triangle, the ratio of the opposite side to the hypotenuse side is equal to the sine angle between adjacent side and hypotenuse, side.

[tex]\sin\theta=\dfrac{b}{c}[/tex]

Here, (b) is the opposite side, (c) is the hypotenuse side and [tex]\theta[/tex] is the angle made between adjacent side and hypotenuse, side.

In the given figure, the hypotenuse side is 9 units long and opposite side is 7 units long.

The angle between adjacent side and hypotenuse is x degrees. Thus, by the right angle triangle property,

[tex]\sin x=\dfrac{7}{9}\\x=\sin^{-1}(0.778)\\x\approx51^o[/tex]

Hence, the value of the angle x, for the given right angle, is approximately 51 degree to the nearest degree.

Answer:

Step-by-step explanation:

Let x represent Josh's rate of travel in miles per hour. After 2 hours, his distance is ...

  distance = speed · time

  distance = x · 2 = 2x

Then 2x is Greg's rate of travel After 5 hours, his distance is ...

  distance = speed · time

  distance = (2x) · 5 = 10x

The distance they are apart is ...

  10x -2x = 256

  8x = 256

  x = 32

__

Josh's rate: 32 miles per hour; Josh's distance = (2 h)(32 mi/h) = 64 miles.

Greg's rate: (32 mi/h)·2 = 64 mi/h; Greg's distance = (5 h)(64 mi/h) = 320 miles.

__

Check: 320 miles - 64 miles = 256 miles . . . . correct separation

Answer:

Step-by-step explanation:

Area Triangles

Area = 1/2 b * h

In a right triangle the two smaller sides are used to find the area

A = 1/2 6 * 4.5

A = 1/2 * 27

A = 13.5

But there are 2 of them so that the area = 2* 13.5 = 27

Area Front side

Area = L * w

L = 13

w = 6

Area = 13 * 6

Area = 78

Area Back side

Area = L * W

Area = 4.5 * 13

Area = 58.5

Bottom  Area

Area = L * W

L = 13

W = 7.5

Area = 13 *  7.5

Area = 97.5

Total Area = 58.5 + 78 + 27 + 97.5

Total Area = 163.5 + 97.5

Total Area = 261

Answer:216X

Step-by-step explanation:

Volume of the sphere = 4/3 πr³

radius r = 6 inches

Volume = 4/3 π(6)³

⇒ 4/3(216)π

⇒ 472π

⇒ 288π cubic inches

Volume of  a cylinder = π r²h

radius r = 6 inches

height h = 6 inches

Volume = π(6)²(6)

⇒ 6³π

⇒ 216π cubic inches

Difference between the volumes = 288π - 216π = 72π
