Maya has 5/6 cup of ice cream. how many 1/4 cup servings are in 5/6 cup of ice cream

1 answer:

6 0

Find the LCD (least common denominator)
$\frac{5}{6} and \frac{1}{4}$

it would be 12 (6x2=12 and 4x3=12)

so you multiply $\frac{5}{6}$ by 2 and get $\frac{10}{12}$
then multiply $\frac{1}{4}$ by 3 and get $\frac{3}{12}$

you get 3 WHOLE servings from $\frac{5}{6}$ cups of icecream

Which is greater? The square root of 121 or the cube root of 125. Explain your answer.

nikdorinn [45]

Answer:

The square root of 121.

Step-by-step explanation:

The square root of 121 is 11. 11x11=121 which makes the square root of 121, 11. The cube root of 125 is 5. Cube roots are numbers that are multiplied by each other to make a number, 125 is 5x5x5 so the cube root is 5. 11 is a greater number than 5 which makes the square root of 121 greater.

Find the work (in ft-lb) required to pump all the water out of a cylinder that has a circular base of radius 7 ft and height 200

Virty [35]

Answer:

work done is equal to 384279168 lb-ft

Step-by-step explanation:

The cylinder has a circular base of 7 ft.

The height of the cylinder is 200 ft

The weight density of water in the cylinder is 62.4 lb/ft^3

First, we find the volume of the water in the cylinder by finding the volume of this cylinder occupied by the water.

The volume of a cylinder is given as $\pi r^{2} h$

where, r is the radius,

and h is the height of the cylinder.

the volume of the cylinder = $3.142* 7^{2}*200$ = 30791.6 ft^3

Since the weight density of water is 62.4 lb/ft^3, then, the weight of the water within the cylinder will be...

weight of water = 62.4 x 30791.6 = 1921395.84 lb

We know that the whole weight of the water will have to be pumped out over the height of cylindrical container. Also, we know that the work that will be done in moving this weight of water over this height will be the product of the weight of water, and the height over which it is pumped. Therefore...

The work done in pumping the water out of the container will be

==> (weight of water) x (height of cylinder) = 1921395.84 x 200

==> work done is equal to 384279168 lb-ft
