A track is 200 meters long. How many times must Julius run around the track to run 3 kilometers ?

Answers

Answer 1

Answer:

Here is how you would do this: If there are 1000 meters in one kilometer, and you know that this track is 200 meters long, then you can find how many times Julius must run around the track in order to reach ONE kilometer:

1000 meters / 200 meters = 5 times in around the track for ONE kilometer.

To find how many times Julius would need to run around to reach THREE kilometers you simply do the following:

5 x 3 = 15 ---> Julius would need to run around the track 15 times in order to reach 3 kilometers.

Y varies directly as x. if x =5 when y=12. find x when y=30

Answers

x = 5 ... y = 12
x = ? ... y = 30

If you would like to know the value of x when y = 30, you can calculate this using the following steps:

5 * 30 = x * 12
x * 12 =150 /12
x = 150 / 12
x = 12.5

The result is 12.5.

How do you calculate elapsed time?

Answers

count forward on a clock.
if you started cleaning at 9:00 and finished at 5:00 the elapsed time would be 8 hours.
elapsed time is the time that passes from the start of an activity to the end of an activity.

Elapsed time is the amount of time taken in order todo a certain action. For example, i you were to set off for school at exactly 9:00am and arrive back at 3pm, then you would have been at school for 6 hours. In other words, the elapsed time was 6 hours.

A movie theater needed 48 popcorn buckets. If each package has 9 buckets in it, how many packages will they need to buy?

Answers

the will need 6 boxes because 9 times 5 is 45 and you need 3 more boxes to make 48 buckets

If they have 48 buckets and each package makes 9 buckets all you have to do is divide 48/9 = 5.3 so all you need is 6 packages because 5.3 isn't sold so 6 or 5 and a small one.

PLEASE HELPA yearbook printer charges based on the number of pages printed. Here is a table that shows the cost of some recent yearbooks.

Number of pages 50 100 150 200
Cost 1.55 2.25 2.95 3.65

Which equation gives the cost, y, in terms of the number of pages, x?

A.

y = 0.014x + 49.15

B.

y = 0.014x + 1.55

C.

y = 0.014x + 0.85

D.

y = 58.8x + 0.85

Answers

First, you have to find the slope.
(3.65 -2.95 )/ (200-150) =m
And then you use like the point-slop form, you can just take a random point and plug it into the equation and solve.
For example, y-3.65= 0.014 (x-200) and you distribute 0.013x-2.8=y-3.65
Add 3.65 on both sides
y=0.014x +0.85

Sorry if this was confusing.. D:

C. if you plug the x and y values in the equation balances out and both sides are equal :)

Two spherical balloons are filled with water. The first balloon has a radius of 3 cm, and the second has a radius of 6 cm.How much more water is in the larger balloon than in the smaller balloon?
Use 3.14 to approximate pi, and express your answer in the hundredths.

cm3

Answers

You use the volume formula for a sphere, or V=4/3*pi*r³;
so the first balloon (3cm) has a volume of 113.1.
The second balloon (6cm) has a volume of 904.78.
Therefore, you do 904.78-113.1, getting 791.68 cm³

The answer is: 791.28
