9m 7.2m 3m find the volume
skelet666 [1.2K]

Answer:

<u>The volume of the prism is 97.2 m³</u>

Step-by-step explanation:

Let's recall that the volume of a triangular prism is base * height and the base is a triangle, then the formula is as follows:

Volume = 1/2 (base of the triangle * height of the triangle) * height of the prism

Replacing with the real values, we have:

Volume = 1/2 (7.2 * 9) * 3

Volume = 32.4 * 3 = 97.2 m³

<u>The volume of the prism is 97.2 m³</u>

Hank has 50 peso, 200 peso and 500 peso bills in his wallet. He has five less 200 bills as 50 bills, and half as many 500 bills
Varvara68 [4.7K]

For an amount of 6250 Peso, Hank have the quantities of the following denominations: 2503 bills of 50 peso, 2498 bills of 200 peso and 1249 bills of 500 peso.

<h3>How to apply systems of linear equations in real life equations</h3>

In this question we must translate the statement of the problem into mathematical expressions and then we must solve the resulting system. We need three equations that describe the quantities of 50 peso, 200 peso and 500 peso bills:

<em>y = x - 5</em>     (1)

<em>0.5 · y =</em> <em>z</em>    (2)

<em>x + y + z = 6250</em>     (3)

The solution of the system of <em>linear</em> equations is described below:

<em>x =</em> 2503, <em>y =</em> 2498, <em>z =</em> 1249

For an amount of 6250 Peso, Hank have the quantities of the following denominations: 2503 bills of 50 peso, 2498 bills of 200 peso and 1249 bills of 500 peso. \blacksquare

2. A student had taken six tests and received scores of 88, 73, 81, 83, 79, 94. The seventh test
Veronika [31]

Answer:

a) 83

b) mean and mode are both 83

Step-by-step explanation:

a) mean is the average. so add all the numbers and divide by the number of numbers.

<u>88 + 73 + 81 + 83 + 79 + 94 + T</u> = 83

7

b) median - put the numbers in numerical order, smallest to largest, what is the middle number (4th number) 73, 79, 81, 83, 83, 88, 94

mode - which number shows up most frequently?
