The base area is 14 in ² 
The volume is 30.8 in ³ 
For a prism of any cross-sectional area,
Volume = base area * height
=>
30.8 = 14 * height
Solve for height
Height = 30.8/14 = 2.2 inches.

Ans. Joseph has to make the box 2.2 inches high.

19.  Hexagonal prism
Given 
Cross section area = 17.01 m ² 
Height = 16.2 m

Using above formula for volume,
Volume = 17.01 m ² * 16.2 m
=275.562 m ³ 

Answer: The volume of stone is 275. 56 m ³ approximately.

Consider the exponential functions below.
klio [65]

The functions in order from least to greatest according to their average rates of change are function f at the interval [1,2], function h at the interval [0,2] and function g at the interval [2,3]

<h3>How to order the functions?</h3>

The rate of change is calculated using:

m = \frac{y_2 -y_1}{x_2 -x_1}

For function g at the interval [2,3], we have:

m = \frac{g(3) - g(2)}{3- 2}

This gives

m = \frac{20 - 4}{3- 2}

m =16

For function h at the interval [0,2], we have:

m = \frac{h(2) - h(0)}{2- 0}

Where:

h(2) = 3(3)^2 - 9 = 18

h(0) = 3(3)^0 - 9 = -6

This gives

m = \frac{18 + 6}{2 - 0}

m = 12

For function f at the interval [1,2], we have:

m = \frac{f(2) - f(1)}{2- 1}

This gives

m = \frac{12 - 6}{2 - 1}

m = 6

Hence, the functions are function f at the interval [1,2], function h at the interval [0,2] and function g at the interval [2,3]

Lila is building a slide for her kids. The ladder is 3 meters tall and the slide is 5 meters long. What is the distance between
lisov135 [29]

Answer:

Step-by-step explanation: For a problem like this, it’s best to use Pythagorean Theorem which is a^2+b^2=c^2 .

In this problem they gave us a and c already so we are trying to find b.

3^2+?=5^2

9+?=25

25-9=16

Find the square root of 16 which is 4

Answer: The distance between the ladder and the slide is 4 meters

Is there a rational number between 1/7 and 1/8
telo118 [61]
1/7 = 2/14 =  <span> <span> <span> 0.1428571429 </span> </span> </span>
1/8 = 2/16 =  0.125
2/15 = <span> <span> <span> 0.1333333333 </span> </span> </span>
So, 2/15 is between 1/7 and 1/8
(and there are an infinite amount of numbers between 1/7 and 1/8)
