Answer:

Q.2: 39, Q.3: 20 cups

Step-by-step explanation:

Q.2 Dog/Cat = 2/3

when Dog = 26,

26/cat = 2/3

cat = 26 x 3 / 2 = 39

Q.3 Sugar/Flour = 3/5

when sugar = 12 cups,

12/Flour = 3/5

Flour = 12 x 5 / 3 = 20 cups

Find the volume of the composite figure.

lana66690 [7]

Answer:

To find the volume of this composite figure, we will need to first separate it into the two rectangular prisms that make up the larger figure (You seem to have already figured that step out =) ). Let us start with the larger prism. The formula for the volume of a rectangular prism is length * width * height.

A fitness club has two options, one for members and one for nonmembers. Members pay a one-time registration fee of $12 plus $8 p

Len [333]

Answer:

Part 1) The system of equations is

$C=8n+12$ ----> equation 1

$C=10n$ ----> equation 2

Part 2) The graph in the attached figure

Part 3) The number of gym visits must be greater than 6

Step-by-step explanation:

step 1

Find the system of equations that represent the situation

Let

C ----> the total cost in dollars

n ---> the number of gym visits

we know that

The linear equation in slope intercept form is equal to

$C=m(n)+b$

where

m is the slope or unit rate of the linear equation

b is the C-intercept or initial value of the linear equation

<em>First payment option ---> For Members</em>

we have that

The slope or unit rate is equal to $m=\$8\ per\ gym\ visit$

The C-intercept or initial value is $b=\$12$ --->one-time registration fee

substitute

$C=8n+12$

<em>Second payment option ---> For Non-Members</em>

we have that

The slope or unit rate is equal to $m=\$10\ per\ gym\ visit$

The C-intercept or initial value is $b=\$0$

substitute

$C=10n$

we have

$C=8n+12$ ----> equation 1

$C=10n$ ----> equation 2

Part 2) Upload a graph

using a graphing tool

The graph in the attached figure

Part 3) After how many gym visits is the payment for the member option more beneficial than the payment for the nonmember option?

we know that

If the payment for the member option is more beneficial than the payment for the nonmember option, then the cost for the member option is less than the cost for the nonmember option

The inequality that represent this situation is

$8n+12 < 10n$

solve for n

subtract 8n both sides

$12 < 10n-8n$

$12 < 2n$

Divide by 2 both sides

$6 < n$

Rewrite

$n > 6$

therefore

The number of gym visits must be greater than 6

Identify the type of claim in each research question below.

Alex Ar [27]

Answer:

b.Testing a claim about a single population mean.

Step-by-step explanation:

Hello!

The researcher wants to test the claim that corporation employees work more than 40 hours per week.

The variable of interest is "The number of hours a corporate employee works per week"

The parameter of study, for her to make a valid conclusion about the weekly working hours of the population of corporation employees is the population mean μ.

If the claim is correct, she would expect the population mean of weekly hours the corporate employees work to be greater than 40.

This is an example of a single population mean test.
