Answer:

216.5

Step-by-step explanation:

Pyramid volume=(area of the base)*(height)/3

Pyramid volume=(area of hexagon with side 5)*(height)/3

Area of hexagon is 3*sqrt(3)*(side)^2/2=75*sqrt(3)/2

Pyramid volume=10*(75*sqrt(3))/(2*3)=216.5

Hello!

First you have to find the probability of picking the right numbers

To do this you do the amount of favorable outcomes over the total amount of outcomes

There are 5 favorable numbers and 18 in total

This is a probability of 5/18

For the second number there of 4 favorable numbers and 17 in total since you already picked one

This is a probability of 4/ 17

For the third number there are 3 favorable numbers and 16 in total

This is a probability of 3/ 16

For the fourth number there are 2 favorable numbers and 15 in total

This is a probability of 2/ 15

For the fifth number there are 1 favorable numbers and 14 in total

This is a probability of 1/14

To get the answer you multiply all the probabilities together

5/18 * 4/17 * 3/16 * 2/15 * 1/14 = 1 / 8568

The answer is $\frac{1}{8568}$

Hope this helps!

What’s the unit rate for three dollars for 2 1/2 hours of work

Maru [420]

The unit rate for three dollars for 2 1/2 hours of work will be $1.2 using the concept of unitary method.

<h3>What is unitary method?</h3>

The unitary method is a technique that involves determining the value of a single unit and then calculating the value of the requisite number of units based on that value. The term unitary refers to a single or unique entity. As a result, the goal of this approach is to determine values in reference to a single unit. The unitary technique is a method for determining the value of any necessary quantity by first obtaining the value of the unit (one) quantity.

Here,

$3 for 2.5 hours of work,

1 hour will cost $x,

3/2.5=x/1

2.5x=3

x=$1.2

Using the unitary technique, the unit rate for three dollars for two and a half hours of labour will be $1.2.

32% of 35 pages please help

zepelin [54]

In order to answer this, first convert every percentage into decimal value.
The decimal value of 32% is 0.32. We just move two decimal places to the left.

Next move is to multiply the converted percent to the whole or total.
So,
= 0.32 * 35
= 11.2
Take note, there are no decimal pages. So the final answer is 11.
There are 11 pages.
