pls help its last question I need this to get 80% if I don't I have to do it again​

When we're solving with scale factors, we either divide or multiply.

If the shape becomes larger, we multiply to get the new length.

If the shape becomes smaller, we divide to get the new length.

We're given:

Because the shape becomes larger, we have to multiply the original side length by the scale factor, 6, to get the new side length.

2.5 x 6 = 15

Therefore, the missing side length is 15 units.

15 units

Answer:

6

Answer: 27.62

Step-by-step explanation:

plug in 2.3 wherever 'n' is

I'm assuming that the '2' in 8n2 is an exponent

2.3 + 8(2.3)² - 17 =

Using PEMDAS

start out with exponent since there isn't any parenthesis  

(2.3)² = 5.29

2.3 + 8(5.29) - 17

move on to multiplication

8(5.29) = 42.32

2.3 + 42.32 - 17

with addition and subtraction, you do whichever comes first and since this equation starts with addition we'll start there

2.3 + 42.32 = 44.62

then the subtraction

44.62 - 17 = 27.62

To solutions for the questions on two quantities are;

1. Time (in hours) and the miles of road paint. The independent quantity is time (t), and the dependent quantity is miles of road painted (m). t for time and m for miles. The equation that relates these two quantities is: m = 9.5 + 0.25t

2. The rate at which the painting crew is painting the road, which is 0.25 mile per hour. This means that for every hour the crew works, they paint 0.25 mile of the road.

3. 10 miles

4. 10 more hours to complete half of the job.

                                                  -36                   0

1. The equation m = 9.5 + 0.25t represents a linear relationship between two variables, m and t.

The equation indicates that the crew has already painted 9.5 miles before they start painting at the rate of 0.25 mile per hour. As the crew continues to work (increasing t), the total miles painted (m) increases by 0.25 miles for every additional hour they work. The equation helps to determine the total miles painted by the crew after a certain amount of time.

If the crew works for another 2 hours, we can find the total miles they will complete using the equation:

m = 9.5 + 0.25(2)

m = 9.5 + 0.5

m = 10

The Department of Transportation in each state is responsible for the improvements and repairs of that state's roads. One important job is to repaint the road lines that have worn away or faded. A painting crew is painting a 24-mile stretch of road. They have already completed a total of 9.5 miles of the road. The crew has been painting at a rate of 0.25 mile per hour and continues to paint at the same rate.

1 Identify the two quantities that are changing in this situation, identify the independent and dependent quantities, and define the variables for these quantities. Then write an equation that relates the two quantities.

2 What is the unit rate of change in this situation? Explain.

3 How many total miles of the road will the crew complete if it works for another 2 hours?

4 How many more hours does the crew need to work to complete half of the job?

A circle graph is defined as a pie chart. The graph is in the shape of a circle with different wedges that each represent a percentage of a total. These wedges often look like pieces of pie, which is why the circle graph is sometimes referred to as a pie chart.

We are given:

Total number of students randomly selected = 450 students

Percentages:

Drama = 14%

Sports = 22%

Documentaries = 24%

Reality = 20%

Thus:

Sci-Fi = 100% - (14% + 22% + 24% + 20%)

Sci-Fi = 22%

Thus:

Number of Sci-Fi preference = 22% * 450 = 99

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

2.51 x \(10^{8}\)

Step-by-step explanation:

This is the answer because:

1) All we have to do is subtract 4.9 and 2.39

4.9 - 2.39 = 4.90 - 2.39 = 2.51

2) Next, we just multiply 2.51 with \(10^{8}\) which leave us with 2.51 x \(10^{8}\)

Answer:

4939.22 feet cubed.  

Step-by-step explanation:

The formula for the volume of a cylinder is V=3.14*r^2*h

First we square the raidus, which is 11 in this problem.  11 squared is 121.

Next we multiply everything together.

3.14*121 is 379.94.  Then, 379.94 * the height, which is 13, is 4939.22.

Since our answer is already rounded to the nearest hundredth, the answer to this problem is 4939.22

Answer:

60

Step-by-step explanation:

these are alternate angles between two parallel lines.

which means that 120=2x

so u can calculate the value of x through this equation.

120=2x

120/2=x=60

The answer would be 3.2, since .2 is equivalent to 1/5 ^^

Answer: 32

Step-by-step explanation:

The only numbers that can have 2 digits and two of which equal to five can only be:

3+2

2+3

4+1

1+4

So the numbers are: 41,14,23, and 32.

41-9=32

14-9=5

23-9=14

32-9=23

Since the question is asking for the number who’s difference is the reverse of one of the numbers. The only possible answer is 32 because 32-9= 23. (23 is the reverse of 32)
