The graph shows how the mass of copper
changes as the volume of the element changes
and the density remains constant.
picture
Which of these bests represents the rate of the
change in the mass of copper with respect to the
volume?
a.4/33 g/cm^3
b.19/41 g/cm^3
c.8 1/4 g/cm^3
d.4 4/7 g/cm^3

Answers

Answer 1

Answer: 8 1/4g/cm³

Step-by-step explanation:

Given the graph :

The rate of change in the mass of copper with respect to volume :

To obtain this, we find the slope or gradient of the graph:

Gradient = Δy / Δx = (y2 - y1) / (x2 - x1)

Drawing a right angled triangle on the anybpart of the line of best fit:

y2 = 40 ; x2 = 4.75 ; y1 = 16 ; x1 = 2

(y2 - y1) / (x2 - x1)

= (40 -16) / (4.75 - 2)

= 24 / 2.75

= 2400/275

= 8.727 g/cm^3

Due to unit and graph scale,, the slope is closest to 8 1/4g/cm³

I only know how to do this in division, not multiplication

Answers

Answer:

360 × 30

= (360 × 3) × 10

= 1080 × 10

= 10800

Step-by-step explanation:

For the first two blanks, we will have to find a pair of factors of 30 that will make this the easiest to solve. Lets pair up all of the factors of 30.

1, 30

2, 15

3, 10

5, 6

So now we have found all of the factors of 30. We can eliminate 1 and 30, since we will just end up with 360 × 30 in the second line. We could use 2 and 15, but we will end up with _____ × 15 in the second line, which would be more difficult to solve for than the other two options. Now, you should use any one of the final two pairs of factors. I would use 3 and 10, since I find it much easier to multiply something by 3 and 10 than 5 and 6.

Lets put 3 in the first blank and 10 in the second blank. We will end up with:

(360 × 3) × 10

Now 360 × 3 would be 1080. So the second line would be:

1080 × 10

1080 × 10 would equal 10800. So the final line and the final blank would be:

10800

So in order, the lines would be:

= (360 × 3) × 10

= 1080 × 10

= 10800

I hope you find my answer and explanation to be helpful. Happy studying.

Help!!!! I don’t really understand sloped so any help would be helpful.

Answers

Answer: The slope is -2.

Step-by-step explanation:

Since the line is going through the origin it means that if you find a point on the line and divided the y coordinate of point by it's x coordinate then you will get the slope or the constant change value.

The equation of a proportional line says that y = kx where k is the slope.

And to find k, you will divide y by x.

One point that is located on the line is (-1,2) The y coordinate is 2 and the x coordinate is -1.

Divide 2 by -1 to find the slope.

2/-1= -2

This means the slope is -2.

Your baseball team is selling bags of popcorn to raise money for a trip. For each bag of popcorn you sell, $3 goes towards your trip. You hope to earn at least $150 for the trip. Write and solve an inequality that represents the numbers x of bags of popcorn you must sell to reach your goal.

Answers

Answer:

x > 50

Step-by-step explanation:

Let

x = number of bags of popcorns to sell

Price of each bag of popcorn = $3

You hope to earn at least $150 for the trip.

At least in inequality = >

The inequality is

Price × quantity of popcorns to sell > 150

3x > 150

Divide both sides by 3

x > 150 / 3

x > 50

Avery and Carmen both have summer jobs Avery gets paid $360 every four weeks, and gets paid $480 every six weeks summer break lasts a total of 12 weeks who earn more money during summer break every earns dollars per week Carmen earns dollars per week

Answers

Answer:

Avery earns $1,080 during summer

Avery weekly earnings = $1,080 / 12

= $90

Carmen earns $960 during summer

Carmen weekly earnings = $960/12

= $80

Carmen earns more money during summer break

Step-by-step explanation:

Avery payment = $360 every four weeks

Carmen payment = $480 every six weeks

summer break lasts a total of 12 weeks

Avery pay during summer = Total summer break weeks / 4 weeks × payment per 4 weeks

= 12 / 4 × $360

= 3 × $360

= $1,080

Carmen pay during summer = Total summer break weeks / 6 weeks × payment per 6 weeks

= 12 / 6 × $480

= 2 × $480

= $960

Avery earns $1,080 during summer

Avery weekly earnings = $1,080 / 12

= $90

Carmen earns $960 during summer

Carmen weekly earnings = $960/12

= $80

Carmen earns more money during summer break

Answer:

Step-by-step explanation:

Avery earns $1080 in 12 weeks
