Jan has a kids pool that holds 20 gallons of water. It drains as a constant rate. When Jan first saw the kids pool, it contained 14 gallons. Six minutes later, the pool contained 10 gallons of water. At what rate is the amount of water in the pool changing? Use a signed number, and include the unit of measurement in your answer.

Answer:

Radius: 7 cm, Diameter: 14 cm

Step-by-step explanation:

Correct me if I'm wrong, but I understood that 14 cm is the length of the line segment drawn across the circle. We know that the definition of the diameter is "any straight line segment that passes through the center of the circle and whose endpoints lie on the end of each circle", which can be defined as the line that is shown with a length of 14 cm. It is also known that the radius, a line drawn from the center of the circle to an endpoint, is always half of the diameter, which in this case is 14 cm, so the radius would be 7 cm.

Yeah, I don't get it either.....

Answer: $10.8

Step-by-step explanation: Let 6 represents how many cheeseburgers was spent. x represents the cost of each cheeseburger that we don't know yet, and 64.80 represents the total cost. 6*x=64.80 x = 10.8

64.80 ÷ 6 = 10.8. So the each cheeseburger cost $10.8. You can find out what these variables are buy dividing 64.80 and 6. You will get your answer.

Answer:

25.

Step-by-step explanation:

Whenever you attempt to solve an equation with multiple operations, remember this: PEMDAS

**THIS IS THE ORDER IN WHICH YOU SHOULD SOLVE EQUATIONS WITH MULTIPLE OPERATIONS.**

First, we solve what is in parenthesis.

20+(5 x 2/5) + 3

5/1 x 2/5 = 10/5 = 2 (simplified)

Then, replace the equation with the answer.

20 + 2 + 3

Secondly, there are no exponents.

There is no multiplication nor division.

However, there is addition.

20 + 2 + 3

20 + 2 = 22

Now, we solve the remaining addition problem.

22 + 3 = 25.

Therefore, 20+(5 x 2/5) + 3 = 25.

Answer: 15

Step-by-step explanation: The scale factor is 5. The measure of I'J' is 75. To find the measure of the side of the initial image, we just have to divide 75/5.

Answer:

#5 = option a (129.38 miles):

We are told that the cities are 17.25 inches apart, and that 2 inches equal 15 miles. First we have to divide 17.25 inches by 2 we end up with 8.62500 inches (not simplified yet). Next, we just take 8.62500 inches and multiply that with 15, which leaves us with 129.37500 inches. Then we just round that to the nearest hundredth which will give us 129.38 inches which means 129.38 miles as well!

#2 = option a (2.4 inches)

We know that bigger rectangle's length is 16 inch and that smaller rectangle's length is 3.2 inches. We just have to calculate the decrease of the length and we do that by dividing. We have to do 16 inches divided by 3.2 inches which equals 5. (You can double check that by multiplying 3.2 inches by 5 which would equal 16 inches) Now to find the width of the smaller rectangle, we just have to divide the width of the bigger rectangle, which is 12 inches, by 5 which would give us 2.4 inches!

#4 = ?

#6 = option c (7.2cm)

So basically I just did 25cm divided by 10cm which equals 2.5cm. (You can also do 25cm divided by 2.5cm to get 10cm if you want to double check). Then I just did 18cm divided by 2.5 cm which led me to the answer 7.2cm)

#3 = ?

Answer: A

Step-by-step explanation: 17.25/2=8.652

8.652*15=129...

rounded it would be equivalent to answer choice A.

Answer:

101.25 km

Step-by-step explanation:

To solve, we need to first find how much she drives in one minute and then multiply that by the number of minutes she drives.

1.5 km = 2 minutes

divide both sides by 2.

1 minute = 0.75 km

2.25 hours = 2.25 * 60 =  135 minutes

Multiply the speed by the time to find distance.

135 * 0.75 = 101.25 km

Thus, she covered 101.25 km in 2 1/4 hours.

Answer:

4.20

Step-by-step explanation:

"1" is in the tenths place, so we look at nine to see if its bigger or smaller than 5, it is so we round up to .20 giving us 4.20

(I also feel this isnt the whole question, but this is the answer for this part anyway.)

Answer:

Step-by-step explanation:

Note that there are 5 different vegetables, so the area devoted to each is 1/5 of the total garden area:

Remember that the radius of a circle is half its diameter.  Here the radius is 54s/2, or 27s.

The area of the entire circle is (pi)(radius)^2, or

(3.14)(27 s)^2, or

2289 s^2

and 1/5 of that is 457.8 s^2

Note 1:  It's ' pi, ' not 'pie.'

Note 2:  Your  ' s '  is not a recognized unit of length.  What does your s represent?

Answer:

I would best say mean.

Answer:

Income from $ 4000 at 5 % in one year = $ 4000 of 5 %.

= $ 4000 × 5/100.

= $ 4000 × 0.05.

= $ 200.

Income from $ 3500 at 4 % in one year = $ 3500 of 4 %.

= $ 3500 × 4/100.

= $ 3500 × 0.04.

= $ 140.

Total income from 4000 at 5 % and 3500 at 4 % = $ 200 + $ 140 = $ 340.

Remaining income amount in order to have a yearly income of $ 500 = $ 500 - $ 340.

= $ 160.

Total invested amount = $ 4000 + $ 3500 = $7500.

Remaining invest amount = $ 10000 - $ 7500 = $ 2500.

We know that, Interest = Principal × Rate × Time

Interest = $ 160,

Principal = $ 2500,

Rate = r [we need to find the value of r],

Time = 1 year.

160 = 2500 × r × 1.

160 = 2500r

160/2500 = 2500r/2500 [divide both sides by 2500]

0.064 = r

r = 0.064

Change it to a percent by moving the decimal to the right two places r = 6.4 %

Therefore, he invested the remaining amount $ 2500 at 6.4 % in order to get $ 500 income every year.

Answer:

Using linear interpolation on the interval [15,23] that would be

9.5 + (22-15)/(23-15) * (11.9-9.5) = 11.6

That is, since 22 is 7/8 of the way from 15 to 23, he should produce a value 7/8 of the way from 9.5 to 11.9

The correct answer is 11.9

I took the test, this is my third time answering this question.

I explained everything but all got erased, anyways the answer is 11.9

Answer:

4: 25%

5: 75%

6: 50%

Step-by-step explanation:

4. Since 3 out of 12 were salmon fillets, 3/12 of the specials were fillets. And since, 3/12=1/4 and 1/4=25%, it tells us that 25% of the dinner specials were salmon fillets.

5. 12/16=6/8=3/4=75% 75% were gingerbread cookies.

6. 35/70=5/10=1/2=50% 50% of the snacks were carrot sticks.
