Miranda wants to buy pencils printed with the school mascot. The graph below represents the cost for different numbers of pencils.

Number of pencils on x axis and cost on y axis.

We have to take any point from graph.

Let the point be (100,12)

Let x be the cost of each pencil be x.

100x=12

Divide both sides by 100

x=12/100

x=0.12

Therefore cost of each pencil be 0.12

Division

The division allows us to divide or 'share' numbers to find the answer to a problem.

For example, to evenly share 10 sweets between 5 kids, we use division to find 10/5 = 2 sweets per kid.

It's given a high school football stadium has 3,892 seats distributed in 14 sections and each section has the same number of seats.

To find the number of seats in each section we use division:

3,892 seats / 14 sections = 278 seats per section

At the end of a snowstorm, Ellie had 16 inches of snow on her lawn. The temperature then increased and the snow began to melt at a constant rate of 1 inch per hour. Assuming no more snow was falling, how much snow would Ellie have on her lawn 4 hours after the snow began to melt? How much snow would Ellie have on her lawn after tt hours of snow melting?

Answers

Answer:

12 inches

Step-by-step explanation:

1 x 4 = 4

16 - 4 = 12

Answer:

Snow after 4 hours: 16 Show after t hours: -1t

Step-by-step explanation:

Snow after 4 hours:

starting amount = 16

melted snow= inches per hour×4

=1×4

final amount= starting amount−melted snow

= 16−4

=12

Snow after t hours:

starting amount= 16

melted snow= inches per hour×t

=1×t

=1t

final amount= starting amount−melted snow =16-1t

Triangle a(-2,3), b(5,4) c(0,-4) is dialated by a scale factor of 3. The center of the dialation is at the origin. Select the Correct coordinates for the new triangle.

Answers

Answer:

New coordinates of triangle are:

A(-6,9), B(15,20), C(0,12)

Option A is correct option.

Step-by-step explanation:

Triangle A(-2,3), B(5,4) C(0,-4) is dilated by a scale factor of 3. The centre of the dilation is at the origin. Select the Correct coordinates for the new triangle.

When a triangle is dilated by a scale factor, we multiply the scale factor with all the coordinates of the triangle.

So, We have A(-2,3), B(5,4) C(0,-4)

Dilation by a scale factor of 3

We get

A = 3(-2,3) = (-6,9)

B = 3(5,4) = (15,20)

C = 3(0,4) = (0,12)

So, New coordinates of triangle are:

A(-6,9), B(15,20), C(0,12)

Option A is correct option.

The temperature is changing at a constant rate of –0.75ºC per half hour. At 6:45 PM, the temperature was –4.6ºC. At what time was the temperature –2.1ºC? Be sure to include AM or PM in your answer.

Answers

Answer:

5:05 PM

Step-by-step explanation:

Each 30 minutes, we have a change of -0.75

So in an hour , we will have a change of -0.75 * 2 = -1.5

since -2.1 is greater than -4.6, this indicates that it was a time before 6:45 PM

so, let us find the temperature drop

That would be;

-2.1-(-4.6) = -2.1 + 4.6 = 2.5

So let us find the number of half hours

That would be;

2.5/0.75 = 3 1/3 half hours

3 half hours is 90 minutes

1/3 half hour is 1/3 * 30 = 10 minutes

Total number of minutes is;

90 + 10 = 100 minutes

So let us count 100 minutes before 6:45 PM

120 minutes before would be;

4:45 PM

but we want 100 minutes, so we have to add 20 minutes

That would be;

4:45 PM + 20 minutes

= 4:65 which is 5 : 05 PM
