Sheldon can read 9 pages in 15 minutes. Betty can read 18 pages in 1 hour. Explain how you could use a table or graph to
find how much longer it would take Betty to read a 360-pageants book than Sheldon.
Make a table of
Betty hours longer to read the book.

Sheldon Can Read 9 Pages In 15 Minutes. Betty Can Read 18 Pages In 1 Hour. Explain How You Could Use

Answers

Answer 1

First step, make ratios:

Pages: time

Sheldon: 9 pages: 15 minutes

Betty: 18 pages: 60 minutes (1 hour)

To find how long it would be for 360 you divide:

9/15 is 0.6 pages: 1 minute and 18/60 is 0.3 pages per minute

When you make the table here would be the equation:

y=.06x for Sheldon and y=.3 for betty (plug in times and create a table)

Answer:

Step-by-step explanation:

3/7 = m/35

7 x ? = 35

7 x 5 = 35

so 3 x 5 = 15

Answers

NATEMATHENY21, you are incorrect because the problem says the car is 10 feet long and the model is 8 inches long so the ANSWER WOULD BE 10:8!!!!
The correct answer would be 10:8

This is because it asks what the ratio of length of car to length of model.
Therefore. It should be structured like:
Length of car : Length of model

Length of car = 10
Length of model = 8

So the answer is:
10:8

Answers

For this equation the easiest thing to start with ratios:

16:4 (scale of 4 due to 4 x 4 being = to 16)

For the y-2 to find y you first will put 8/4 (your scaling back), so 2 so 4-2 would be 2 which makes that equal to y.

Knowing that 8 is the size on the one side these are equal on the top so x-3 had to equal 8, so 11-3=8 so...

x=11

y=2

Find the slope of the line given its graph.

Answers

Answer:

-3

Step-by-step explanation:

Use rise over run to find the sloe

Point are (1,-1) and (0,2)

Pick one point, if we pick (0,2) we can see how the y value decreased by 3 and increased by 1

-3/1

You can do this with any points on a slope

-3 over 1 because of you use rise over run you get -3/1

Find the slope of the line given its graph.

Answers

Slope = Rise/Run
Using the two points, rise (y) = 4 and run (x) = 2, so the slope is 2.

You can also use the slope formula:
(Y2 - Y1)/(X2 - X1)
Rise over run so it’s 4 over 2 the 4 is the rise (y)
And the 2 is the run (x)
You can simplify 4/2 with 2 so you just divide 4 divided by 2 which is 2
Then 2 divided by 2 is 1

Which then gives you 2/1 which is just 2
So the answer is 2

Raise the product to the power (xy)^4

Answers

Answer:  x^4y^4

Explanation:

Each term inside is raised to the fourth power.

The rule is (ab)^c = a^c*b^c

An example:

(2*3)^4 = 6^4 = 1296

(2*3)^4 = 2^4*3^4 = 16*81 = 1296

Therefore, (2*3)^4 = 2^4*3^4

WORTH 50 POINTS!!!!!!!!!! a gardener made a scale drawing of a lawn with a scale factor of 1:15. the dimensions of his garden are 6 inches long by 3 inches wide. his partner plans to make another scale drawing of the lawn, but with a scale of 1:5
. what are the dimensions of his scale drawing?

Answers

Answer:

D. the length is 18 inches and the width is 9 inches.

Step-by-step explanation:

Given information:

Scale = 1 : 15.Dimensions of the lawn in the scale drawing = 6 in × 3 in.

Therefore, to find the actual dimensions of the lawn, multiply the given scale dimensions by 15:

⇒ Length = 6 × 15 = 90 in

⇒ Width = 3 × 15 = 45 in

If the gardener's partner plans to make another scale drawing of the lawn with a different scale of 1 : 5, to find the dimensions of his scale drawing, divide the actual dimensions by 5:

⇒ Length = 90 ÷ 5 = 18 in

⇒ Width = 45 ÷ 5 = 9 in

Therefore, the dimensions of his scale drawing are the length is 18 inches and the width is 9 inches.

An alternative way to approach this problem is to calculate the difference between the two scales.  It is clear that the original scale of 1 : 15 is 3 times the new scale of 1 : 5.  Therefore, simply multiply the original dimensions by 3 to find then new dimensions of the scale drawing with a scale of 1 :5.

I’m pretty sure it’s just 5x for AB and x for EF.
AB = 10
EF = 2


Step-by-step explanation:
to find the scale factor you have to divide the bigger scale by the smaller one which would be
(5x)/5 and 4/x
since both scale factors should be the same you can set them even to each other
(5x)/5=4/x
solve for x
(5x)15=4/x
x=4/x
y^2=4
x=2

Answer:

y=4x

Step-by-step explanation:

if you look at the line you'll see it takes 4 x's to = 1 y, every time you go right 1 you go up 4

Answer:

The slope is 4.

Step-by-step explanation:

Step 1:

Slope can also be found by using the formula, Y2-Y1/X2-X1

In this case, our first point is the origin, so x would be 0 and y would be 0. On the second point, our x is -1, and our y is -4.

So, we can make the solution, -4-0/-1-0.

You can simplify this into, -4/-1, and then into 4.

Therefore, the slope is 4.

Step 2:

M is our slope, so in our y=mx equation our m = 4.

If you substitute in the m, you get y=4x.

Answer:

y=4x.
