A running track design is composed of two half circles connected by two straight-line segments. Garrett is jogging on the inner lane (with radius r) while Devin is jogging on the outer (with radius R). If r= 30 meters and R= 33 meters, how much longer does Devin have to run to complete one lap?​

Answers

Answer 1

Answer:

18.86 m

Step-by-step explanation:

From the given question, both covers the same distance of the straight line segment.

For the inner lane,

length of arc of its semicircle = [tex]\pi[/tex]r

                                   = 30 x [tex]\frac{22}{7}[/tex]

                                   = 94.2857

So that,

the total length for the two halves of the inner lane = 2 x 94.2857

                                                                  = 188.5714 m

For the outer lane,

length of arc of its semicircle = [tex]\pi[/tex]r

                                                 = 33 x [tex]\frac{22}{7}[/tex]

                                                 = 103.7143

The total length for the two halves of the outer lane = 2 x 103.7143

                                                                  = 207.4286 m

The difference between the two = 207.4286 - 188.5714

                                                       = 18.8572 m

Therefore, Devin would run 18.86 m more to complete one lap.

Milo drinks 2/5 of a bowls of water in 1/3 of an hour. How many hours will it take Milo to drink an entire bowl of water?

Answers

Answer:

It would take Milo 5/6 of an hour to drink an entire bowl of water.

Step-by-step explanation:

In this case, you can use a rule of three to find how many hours it will take to drink 1 bowl of water given that 2/5 of a bowl of water takes 1/3 of an hour:

2/5 of a bowl → 1/3 of an hour

      1 bowl      →         x

x=(1*1/3)÷2/5

x=1/3÷2/5

x=(1*5)/(3*2)

x=5/6

According to this, the answer is that it would take Milo 5/6 of an hour to drink an entire bowl of water.

Marta spent a total of $34.29

Step-by-step explanation:

Since she bought 3 towels for $8.50 each you would do 3 times $8.50 to get $25.50 for the towels and since she bought 5 washcloths for $1.25 each you would do 5 times $1.25 to get $6.25 then you would add the totals to get $31.75. Then you would find out the tax by finding out what 8% of $31.75 is which would be 2.54. So you would add $2.54 to $31.75 to get $34.29. So the total amount of money that Marta spent is $34.29

3 times $8.50 = $25.50

5 times $1.25 = $6.25

$25.50 + $6.25 = $31.75

Based on this data, what is a reasonable estimate of the probability that the Texas Sharpshooters score exactly

Answers

Answer:

The answer is "Its next hockey game is probably the Texas Sharpshooters who've had exactly 1 goal 0.5".

Step-by-step explanation:

The exploratory probabilities are called chances of possible dangers based on previous cases.

[tex]Experimental \ probabilities = \frac{Appropriate \ results}{Total\ results}[/tex]

The chance which Texas Sharpshooters will be scoring precisely

Next game of 1 goal

If demonstrated at the table:

Positive effects are 1 repeated 4 times

So, positive results [tex]= 4[/tex]

Outcomes total [tex]= 8[/tex]

Odds [tex]= \frac{4}{8} = 0.5[/tex]

The probability that Texas Sharpshooters will achieve exactly 1 goal is 0.5
