Answer:

1.25 miles

Step-by-step explanation:

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

Part A: first multiply 2 by x and -3 → combine all like terms → Add 6 on both sides → subtract 6x from both sides.

Your final answer should be -5

step by step:    4x + 2(x-3) = 4x + 2x - 11

                          4x +2x -6 = 4x + 2x - 11

                                            6x -6 = 6x - 11

                                            6x = 6x -11 +6

                                            6x = 6x -5

                                            6x-6x= -5

                                            0 = -5

Part B: Add all like terms.

Hope this helps! :)

Answer: The answer is 120

Step-by-step explanation:

We know that 36 is 30% of total items

So our equation would be 36/? = 30/100

From there we cross multiply so 36x100 = 3600

From there, we divide 3600 by 100

Therefore, your answer is 120

Circle question of the rug

That you needed answer for is ;

3/4 pi^2  

Step-by-step explanation:

Proof  1/4 pi r^2

We can state the radius of small rug is 3ft

to show Area pi 3^2 = pi 9

If the large rug is 3x this size  

then  pi 9^2 = pi81

So the ratio here is 1 : 9 when 3 cm or 1 : 3 radius

Ratio is 1 : 9 when 1cm or 1 : 3 radius  

When 1 : 9 cm when 5cm or 1 : 3 radius  

So if we are considering an expression of the larger rug  

that shows 3: 1 more radius to that of the small.

1/4 pi^2 becomes 3/4 pi^2 of the smaller rug

As this is 3 x 1/4 pi^2 we show 3/4pi r^2

Answer:

it is 16 - 1/2n

Step-by-step explanation:

if we considered the number as n

Divide the total distance traveled by the total time spent traveling. Your estimated speed should be reletively close to your calculated speed.

Answer:

J' (-2, 2.5), K' (1, 2.5) L' (1, -2.75)

Step-by-step explanation:

With a scale factor of 1/2=.5 you can simply multiply all coordinates by .5 (or divide by 2)

J (-4,5) x 1/2= (-2, 2.5)

K (2,5) x . 5 = (1, 2.5)

L (2, -5.5) /2= (1, 2.75)

Answer:

1. 1/36

2. 9/64

Step-by-step explanation:

First Question:

1. First thing I look for is how many spots are there and how many of them are for each color: both green and orange have 1 spot each out of six spots.

2. The chances of landing on each one is 1/6.

3. Now that they have to land back to back, I multiply the fractions by using the denominator which is 1 in 36 or 1/36.

Second Question:

1. Once again I see there are eight spots and blue has 3 of those.

2. I multiply the chance of it landing on blue on the first time, 3/8, by itself for the second time, 3/8.

3. You multiply the fractions and you get 9 in 64 or 9/64.

========================================================

Explanation:

We have these three rules for scale factors

With those rules in mind, we have enlargements for these transformations.

All of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.

In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.

----------------

We also have these reductions

This is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.

----------------

And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.

The order doesn't matter for this subset, but the order will matter for the other batches of transformations.

Answer:

36 minutes.

Step-by-step explanation:

The best way to solve this is to find how much distance is traveled in a minute and then divide the total distance by the distance traveled in a minute. Now let's apply.

1/4 x 4 = 1 minute, so in this problem, 1/2 x 4 = 1 minute.

1/2 x 4 = 2.

72 / 2 = 36.

Her trip would have taken 36 minutes by car.

Answer:

36 minutes.

Step-by-step explanation:

For every mile she takes it's 1/2 of a minute. Then just do 72/2 and get 36 :)

What do you need help with?

Step-by-step explanation:

Answer:

y = 8x

Step-by-step explanation:

slope-intercept form: y = mx + b when m = slope and b = y-intercept

y-intercept is when the line crosses the y (vertical) axis. This is at (0,0) so b = 0

Next, slope = change in y/change in x

There are 3 points plotted but only 2 are centered on the grid well.

(0,0) and (2, 16)

slope = change in y/change in x

slope = (0 - 16) / (0 - 2)

slope = -16/-2

slope = 8

so when m = 8 and b = 0: y = mx + b

y = 8x + 0 so:

y = 8x

Answer:

y = 8x

Step-by-step explanation:

y-intercept: 0 (because it starts from the origin)

slope: go from the origin (the first point on the whole graph) to the last point of the graph since that way it would be easier... count your way up and after you've counted it should be 8. and since the line is going up, its a positive slope. therefore, the slope is 8

Answer:

It would be 8 inches tall.

Step-by-step explanation:

Here's a real-world problem involving a percent increase with decimals:

Suppose you have a savings account with a balance of $500. The bank offers an interest rate of 2.5% per year. How much will your balance increase after one year, including the interest earned?

To solve this problem, we can use the formula for percent increase:

Percent increase = (new value - old value) / old value x 100%

Let x be the amount of interest earned after one year. Then, the new value of the savings account after one year is:

New value = old value + interest earned

New value = $500 + x

The percent increase is given as 2.5%, which can be written as a decimal as 0.025. Using the formula above, we can write:

0.025 = (New value - $500) / $500 x 100%

Simplifying this equation, we get:

New value - $500 = $500 x 0.025

New value - $500 = $12.50

New value = $512.50

Therefore, the balance of the savings account will increase by $12.50 after one year, which represents a 2.5% increase from the original balance of $500. The new balance will be $512.50.

This sequence  follows a pattern of dividing by two each time. So, you would divide 100 by two, and the resulting number would be divided by two as well. The next occurring numbers would be 50 and 25. I hope this helps! :)

The given point is not on the line.

Step-by-step explanation:

3 represents x

3 represents y

1. Plug in the numbers to x and y variables

y= \(-\frac{2}{3}\) x + 1

3= \(-\frac{2}{3}\) (3) + 1

2. Cancel out the greatest common factor

3=-2+1

3. Solve

3=-1

If the numbers do not equal each other, then the equality is false.

Step-by-step explanation: 1. Plug in the numbers to x and y variablesy=  x + 13=  (3) + 1

2. Cancel out the greatest common factor 3=-2+13. Solve3=-1

Answer:

slope = 4/7 & y-intercept = -2

Step-by-step explanation:

4x - 7y = 14                  (step 1: original equation)

-4x         -4x                 (step 2: remove 4x, BS)

-7y = -4x + 14

7y = 4x - 14                  (step 3: switch signs)

y = 4/7x - 2                  (step 4: divide BS by 7)

In the form y = mx + b, b is the y-intercept and m is the slope. In this case, our b (y-intercept) is (0, -2) or just -2. Our m (slope) is 4/7 (four sevenths).
