Answer:

$12,500 per year

Step-by-step explanation:

rate of change = change in dollars/change in years

So,

Since we know the first answer is 2, we can subtract 82 by 2. Afterwards we can divide by 8 since we are counting by 8s, this gets me 10. 10 + the first number is 11

Answer:

O The maximum height of the water balloon occurs at x = 0.    

O The water balloon is in the air for 2 s.    

O The maximum height of the water balloon is 64 ft.

Step-by-step explanation:

Firstly, by simply looking at the x axis on the graph (time), you will see that it starts at 0 and the 64 ft maximum height is aligned with the starting point of 0 seconds.  

The graph also shows (x axis) the 'time' represented, and as the height rapidly decreases the graph eventually reaches the 2 second mark, going no further and no lower.  

Finally, the graph shows (y axis) the peak of the water balloon's height is 64 ft, as it is the highest number reached while the water balloon was airborne.

The following statement is True.

A true statement to be chosen from the following.

The graph is a demonstration of curves  that gives the relationship between the x and y-axis.

From the graph, the following points are to be noted.
The water balloon is at 64 ft at x = 0.
The water balloon takes 2 sec to reach y = 0.
The water balloon has a maximum height of x = 0.

Thus, points 1,2, and 5 are true.

Answer:

A= 243

B=4

Its because its multiplying itself 5 times for A. And doing it 4 times for B

I think this is correct (I am only in Middle School...)

Step-by-step explanation:

(a) The number of T-shirts sold in the 5th month is 15. (b) The store sells 81 T-shirts in the 27th month.

a. To find f(5), we need to plug x = 5 into the function f(x) = 3x:

f(5) = 3 × 5 = 15

So, the number of T-shirts sold in the 5th month is 15.

b. To find when the store sells 81 T-shirts, we need to solve the equation f(x) = 81:

f(x) = 3x = 81

Now, solve for x:

3x = 81

Divide both sides by 3:

x = 81 / 3

x = 27

So, the store sells 81 T-shirts in the 27th month.

Answer:

[tex](\frac{32}{243})^{-\frac{4}{5}}=39.0625[/tex]

Step-by-step explanation:

Given

[tex](\frac{32}{243})^{-\frac{4}{5}}[/tex]

Required

Solve

[tex](\frac{32}{243})^{-\frac{4}{5}}[/tex]

Express 32 as 2^5 and 243 as 3^5

[tex](\frac{2^5}{3^5})^{-\frac{4}{5}}[/tex]

The exponent can be expressed as 1\5 * -4

So we have:

[tex](\frac{2^5}{3^5})^{\frac{1}{5} * -4}[/tex]

Apply law of indices:

[tex](\frac{2^{5*1/5}}{5^{5*1/5}})^{-4}[/tex]

[tex](\frac{2}{5})^{-4}[/tex]

In indices:

[tex](\frac{a}{b})^{-c} = (\frac{b}{a})^{c}[/tex]

So, the expression becomes

[tex](\frac{5}{2})^{4}[/tex]

[tex](\frac{5^{4}}{2^{4}})[/tex]

[tex]\frac{625}{16}[/tex]

[tex]39.0625[/tex]

Hence:

[tex](\frac{32}{243})^{-\frac{4}{5}}=39.0625[/tex]

Step-by-step explanation:

[tex]\sqrt{25^2-7^2}\\\\=\sqrt{(25-7)(25+7)}\\\\=\sqrt{18(32)}\\\\=\sqrt{9*2*2^5}\\\\=\sqrt{3^2\cdot 2^6}\\\\=\sqrt{(3\cdot2^3)^2}\\\\=3\cdot2^3\\\\=3\cdot8\\\\=24[/tex]

Answer:

24

Step-by-step explanation:

First we compute the number under the radical.

We have 25² = 625 and 7² = 49, so 25² - 7² = 625 - 49 = 576.

Thus, √25² - 7² = √576 = √24², which is 24.

Answer:

43%

Step-by-step explanation:

First, find the total amount of games:

13 + 15 + 2

= 30

Then, to find the percentage of games won, divide 13 by 30:

13/30

= 0.43

So, the team won approximately 43% of its games

Answer: Approximately 43.3%

Work Shown:

13+15+2 = 30 games total

Divide the number of games won (13) over the number total (30)

13/30 = 0.433 approximately which converts to 43.3% of the games won

To convert from decimal form to percent form, move the decimal point over to the right two spaces. Another example would be 0.83 converts to 83%

Do you want to know how to write the decimal number 5.46 as a fraction?

Here we will show you step-by-step how to convert 5.46 so you can write it as a fraction.

You can take any number, such as 5.46, and write a 1 as the denominator to make it a fraction and keep the same value, like this:

5.46 / 1

To get rid of the decimal point in the numerator, we count the numbers after the decimal in 5.46, and multiply the numerator and denominator by 10 if it is 1 number, 100 if it is 2 numbers, 1000 if it is 3 numbers, and so on.

Therefore, in this case we multiply the numerator and denominator by 100 to get the following fraction:

546 / 100

Then, we need to divide the numerator and denominator by the greatest common divisor (GCD) to simplify the fraction.

The GCD of 546 and 100 is 2. When we divide the numerator and denominator by 2, we get the following:

273 / 50

Therefore, 5.46 as a fractio

Step-by-step explanation:

Given the questions:

1. Tara walks a 2 mile route through her neighborhood for daily exercise. It takes her 30 minutes. At this rate, how far can Tara walk in 45 minutes?

Speed = distance / time ; 2 / 0.5 = 4 mph

45 minutes = 0.75 hr

Distance = speed * time = 4 * 0.75 = 3 miles

2. An infant daycare requires 1 teacher for every 4 children. How many teachers are required for 20 children?

1 teacher = 4 children

x = 20 children

x = 20/4 = 5

5 teachers

3. To make purple frosting, you start with white frosting. Then you add 2 drops of red food coloring and 3 drops of blue food coloring. If 4 red drops come out with the first squeeze, how many blue drops should you add?

2 drops of red = 3 drops of blue

4 drops of red = x

x = 12 / 2 = 6 drops of blue

4. Arlen delivers 28 newspapers each morning. The route takes him 40 minutes. If his route increases to 35 newspapers, how long will it take him?

40 minutes

6. On a map, 1 inch represents 50 miles. You measure the distance on the map between two towns as 3 inches How many miles apart are the two towns?

1 inch = 50 miles

3 inch = d

d = 50 * 3 = 150 miles

6. Kelsey earns $5 walking her neighbors' dogs twice a week. At this rate, how much should Kelsey cam if she walks the dogs 6 days each week?

Twice a week = $5

6 times a week = (6/2) * 5 = $15

7. Jeff drove the first 200 miles of a trip in 3 hours. At this rate, how long will the 500 mile trip take, with no stops?

Rate = distance / time = 200 / 3 = 66.667mph

time = 500 /66.667 = 7.5 hours

8. Lisa types 6 pages in 36 minutes. Frank types 5 pages in 30 minutes. Do they type at the same rate?
