How do I solve this using this graph

Dmitry [639]

Can't tell with graph but if the width is 15 more than likely the length is 13 but that is if you use the basic subtraction.

If 7 4/5 of the total came to 109,200, what is the total?

Olenka [21]

Let’s divide this fully into 5ths to make it easier.

7 and 4/5 also equals 39/5.
39 is what we call a prime number so we can’t factor 109200 with it, so all we have left that we can do is divide.
109200/39=$2800
$2800 is 1/5 of the total, so just multiply that by 5 and you have your answer!
2800x5=$14,000.

84 cubic inches 90 cubic inches 100 cubic inches 126 cubic inches

igomit [66]

Answer: Second Choice. 90 cubic inches

Concept:

Here, we need to know how to calculate the volume of a rectangular prism

Volume (rectangular prism) = w · l · h

w = width

l = length

h = height

Solve:

Given information

l = 6"

w = 3"

h = 5"

Given expression

V = w · l · h

Substitute values into the expression

V = (3) (6) (5)

Simplify by multiplication

V = 18 · 5

$\boxed{V_{rectangular prism}=90}$

Hope this helps!! :)

When peanuts are packaged in their shells, most shells have two peanuts inside, but some have three and some only have one. A qu

Oduvanchick [21]

Answer:

H0: p = 0.1 and Ha: p > 0.1

Step-by-step explanation:

At the null hypothesis, we test if the mean or proportion is equal to a certain value.

At the alternate hypothesis, we test if the mean or proportion is less than, more than, or different of the value tested at the null hypothesis.

A quality control inspector wants to determine if more than 10% of all shells contain just one peanut.

The value of 10% = 0.1 is tested, which means that the null hypothesis is $H_{0}: p = 0.1$

Test if it is more than 10% = 0.1, so the alternate hypothesis is: $H_{a}: p > 0.1$
