Pizza Paradise offers 4 types of crust, 10 toppings, and 8 kinds of cheese for the mega calzone. How many different mega calzone
Bumek [7]

Answer:

26880 ways

<em></em>

Step-by-step explanation:

Given

Crust = 4

Toppings = 10

Cheese = 8

Required

Determine the number of ways 3 toppings and 3 cheese can be selected

The number of crusts to be selected was not stated. So, I'll assume 1 crust to be selected from 4.

This can be done in ^4C_1 ways

For the toppings:

3 can be selected from 10 in ^{10}C_3 ways

For the cheeses:

3 can be selected from 8 in ^{8}C_3 ways

Total number of selection is:

Total = ^4C_1 * ^{10}C_3 * ^{8}C_3

Apply combination formula:

Total = \frac{4!}{(4-1)!1!} * \frac{10!}{(10-3)!3!} * \frac{8!}{(8-3)!3!}

Total = \frac{4!}{3!1!} * \frac{10!}{7!3!} * \frac{8!}{5!3!}

Total = \frac{4*3!}{3!*1} * \frac{10*9*8*7!}{7!*3*2*1} * \frac{8*7*6*5!}{5!*3*2*1}

Total = \frac{4}{1} * \frac{10*9*8}{3*2*1} * \frac{8*7*6}{3*2*1}

Total = 4 * \frac{720}{6} * \frac{336}{6}

Total = 4 * 120* 56

Total = 26880

<em>Hence, there are 26880 ways</em>

What is the volume of hemisphere with a radius of 8 ft rounded to the nearest tenth of cubic foot
patriot [66]

Answer:

1072.3ft^{3}

Step-by-step explanation:

A hemisphere is half of a sphere, so the volume V of the hemisphere is the volume of the sphere divided by 2.

V = (2/3)*\pir^{3}

   = (2/3)*\pi(8ft)^{3}

   = (2/3)*\pi*512ft^{3}

   = 1072.3ft^{3}

It is not always helpful to rewrite an equation in standard form as a first step in solving it.
Kitty [74]
The answer to the problem above is True. Standard form of an equation means the right side of the equation should be 0, and everything on the left side. For example, x^2 = 4 , to make this this in standard form you have to transfer number 4 to the left side of the equation making it x^2 - 4 = 0.
In this situation, if you will be asked to look for x, there is no need to make the equation in standard form, you can directly take the square root of both sides of the equation to get x.
