we know that

The cost is directly proportional to the weight, so if the weight is increased by a factor of 4, the cost will also increase by a factor of 4.

therefore

<u>the answer is</u>

the total cost increase by a factor of 4

Answer:

Both sides of the ratio is increased by a factor of four.

Step-by-step explanation:

Ratios given:          <u> Weights </u>         <u> Costs </u>

                                     1                      2

                                     4                      8

                                     6                     12

                                    10                    20

Each cost is the double of its weight, so the base ratio is 1:2. This is where we begin.

When you increase the weight by a factor of four, this is what that side of the ratios change to:    

                   4:2                 8:8                    24:12                   40:20

This changes the base ratio to 2:1. Because the base ratio isn't meant to change, what we did to one side of the ratio we must do to the other to maintain proportionality. So that means the factor of cost increase is also four.

New ratios:

                              4:8     8:32    24:48   40:80

Zayed is helping his classmates get ready for their math test by making them identical packages of pencils and calculators. He h
oee [108]
So 72 pencils and 24 calculators
so greates number of identical calculators

this means
what is the biggest number that we can divide 72 and 24 by and get a whole number
this is called the GCM or greatest common multipule

to find the GCM, you factor 72 and group the like ones
72=2 times 2 times 2 times 3 times 3
24=2 times 2 times 2 times 3
so the common group is 2 times 2 times 2 times 3 or 24
so the greates number of packs is 24

so pencils
72 divided by 24=72/24=3
3 pencils per pack

24 divided by 24=24/24=1
1 calulator per pack


answer is 3 pencils and 1 calculator per pack

What is the solution to the equation?
AleksandrR [38]

Solution of the equation: x=6\frac{1}{2}

Step-by-step explanation:

The equation that we have to solve in this problem is:

13\frac{3}{4}+x=7\frac{1}{4}

The first step to do is to rewrite the mixed fractions as improper fractions. We have:

13\frac{3}{4}=\frac{13\cdot 4+3}{4}=\frac{52+3}{4}=\frac{55}{4}

And

7\frac{1}{4}=\frac{7\cdot 4+1}{4}=\frac{29}{4}

So the equation becomes

\frac{29}{4}+x=\frac{55}{4}

Now we multiply by 4 each term on both sides, and we get

29+4x=55

Now we subtract 29 from both sides,

4x=55-29=26

And finally, we divide both sides by 4:

x=\frac{26}{4}=\frac{13}{2}=6\frac{1}{2}

Which statement is correct for the graph of the specified function?
mash [69]

The correct statement regarding the function plotted in the graph is:

C) The maximum value of the quadratic function occurs at y = 4.

<h3>What is the rate of change of the linear function?</h3>

When x = 0, y = -7, and when x = -5, y = 8, hence the rate of change(change in y divided by change in x) is given by:

R = [8 - (-7)]/-5 - 0 = 15/-5 = -3

<h3>What is the maximum value of the quadratic function?</h3>

It is concave down, hence it has only a maximum value at y = 4 and not a minimum value, hence option C is correct.
