geniusboy [140]

Answer:

Step-by-step explanation:

Number of paperback books = 4

Percentage of total books that were paperbacks = 20%

Let total number of books = x

Hence,

20% of total books = paperback books

20% of x = 4

0.2 * x = 4

0.2x = 4

0.2x / 0.2 = 4 / 0.2

x = 20

Total number of books = 20

1. Find the volume for 5 different spheres by randomly choosing different radii.

Sophie [7]

The volume of the sphere is given by :

V= $\frac{4}{3}\pi r^{3}$

And volume of cylinder is given as :

V= $\pi r^{2}h$

So, as given to select the radius randomly and the height of the cylinder will be the diameter of the sphere.

The radius are = 3, 5, 8, 10, 12

And height will be = 6, 10, 16, 20, 24

1. Volume of sphere with radius 3 = $\frac{4}{3}*3.14*3*3*3= 113.04$ units

Volume of cylinder with radius 3 and height 6 = $3.14*3*3*6=169.56$ units

2. volume of sphere with radius 5 = 523.60 units

volume of cylinder with height 10 = 785.40 units

3. volume of sphere with radius 8 = 2144.66 units

volume of cylinder with height 16 = 3216.99 units

4. volume of sphere with radius 10 = 4188.79 units

volume of cylinder with height 20 = 6283.19 units

5. volume of sphere with radius 12 = 7238.23 units

volume of cylinder with height 24 = 10857.34 units

alexgriva [62]

Answer:

Of the 75 orders, 40 orders correspond to Rob and 35 orders correspond to Juan.

Step-by-step explanation:

Given that Juan and Rob are selling cookie dough for a school fundraiser, having a total of 75 orders, of which 40 correspond to Rob, to determine how many orders correspond to Juan the following calculation must be performed:

75 - 40 = X

35 = X

Thus, of the 75 orders, 40 orders correspond to Rob and 35 orders correspond to Juan.
