Donovan is training for a marathon. He currently can run 1 lap around the track in 0.85 minutes. How long will it take him to run 12.5 laps?

ASAP

Answers

Answer:

10.625

Step-by-step explanation:

Answer:

10 minutes and 37.5 seconds

Step-by-step explanation:

0.85 is 51 seconds. I will be using this because it is easier for me.

Multiply 51 • 12 = 612 seconds for 12 laps. Divide 612 ÷ 60 = 10.2. You get 10.2 minutes. This is 10 minutes and 12 seconds for 12 laps.

Divide 51 by 2 to find how long it takes for 1/2 a lap. You will get 25.5 seconds for half a lap.

Add them together: 10 min 12 sec + 25.5 sec = 10 minutes and 37.5 seconds

14 + 6 + (–2) + (–10) + (–18) + (–26) + (–34) What is the summation notation for the arithmetic series? Enter the correct values for x, y, and z.


x =

y =

z =

Answers

Answer:

total -70

Step-by-step explanation:

x =18

y=-28

Z = -60

An Arithmetic series: 14 + 6 + (–2) + (–10) + (–18) + (–26) + (–34)

The Total value is =  -70

x = 18

y = -28

Z = -60

Calculation of Arithmetic Series

An Arithmetic series: 14 + 6 + (–2) + (–10) + (–18) + (–26) + (–34)

1st an 2nd element difference is = 14 - 6 = 8

2nd and 3rd element difference is = - 6 - 2 = -8

3rd and 4th element difference is = - 2 + 10 = 8

4th and 5th element difference is = -10 + 18 = 8

The difference (x,y and z) is 8 and also it's negative because the series is lowering the previous value.

Now, Proof of x,y and z = - 8

14 - 8 = 6

6 - 8 = - 2

- 2 - 8 = - 10

- 10 - 8 = - 18

- 18 - 8 = - 26

-26 - 8 = -34

Therefore, The value is = total -70

x = 18

y = -28

Z = -60

Answers

Answer:

Step-by-step explanation:

Simplify both sides of the equation as much as possible:

9r + 5 - 4 = 4r + 5r - 12

9r + 1 = 9r - 12

Both sides have "9r" which when cancel out, leave the equation as:

How many gallons of a 15% sugar solution must be mixed with a 5 gallons of a 40% solution to make a 20% solution

Answers

Answer:

20 gallons of 15% solution must be mixed with 5 gallons of 40% solution.

Step-by-step explanation:

40% of 5 gallons is 2 gallons of sugar

x represents the number of gallons of solution to be added.

15% of x is sugar.

The total amount of sugar must be equal to 20% of the final mixture.

The end mixture will be x + 5 gallons

Change percent to decimal for the equation:

.2(x +5) = .15x +2

.2x +1 = .15x +2

.2x - .15x = 2 -1

.05x = 1

x = 20

Check:

.2(20 +5) = .15(20) +2

.2(25) = 3 + 2

5 = 5 true

This means that adding 20 gallons of the 15% solution is adding 3 gallons of sugar [along with 17 gallons of water] to the 2 gallons of sugar in the original mixture.

20% of the 25 gallons, 5 gallons, of the final mixture is sugar. 80% [ 3+17 = 20 gallons] is water.

Assume that when adults with smartphones are randomly​ selected, ​44% use them in meetings or classes. If 8 adult smartphone users are randomly​ selected, find the probability that exactly 2 of them use their smartphones in meetings or classes.

Answers

Answer: The probability is 0.448

Step-by-step explanation:

First, 44% of adults use their smartphones in meetings or classes, then the probability that a random adult uses their smartphone on a meeting is:

p = 0.44

Then the probability that a random adult do not use it is:

q = 1 - 0.44 = 0.66

If 8 adult smartphone users are randomly​ selected, find the probability that exactly 2 of them use their smartphones in meetings or classes.

For a random (and fixed) case, the probability will be equal to the product of the individual probabilities for each person, this leads to:

P = (0.44)*(0.44)*(0.66)*(0.66)*(0.66)*(0.66)*(0.66)*(0.66)

P = (0.44)²*(0.66)⁶ = 0.016

And now we need to consider the different combinations. If we have C combinations, then the probability for the event will be C*P.

Remember that if we have N elements, the total number of different groups of K elements (from these N elements) is:

[tex]C(N,K) = \frac{N!}{(N - K)!*K!}[/tex]

In this case, we have N = 8, and K = 2

Then we get:

[tex]C(8, 2) = \frac{8!}{(8 - 2)!*2!} = \frac{8!}{6!*2!} = \frac{8*7}{2} = 4*7 = 28[/tex]

Then there are 28 different combinations.

This means that the probability is:

Probability = 28*P = 28*0.016 = 0.448

Probability = 0.448

The 24/7 Truck Rental Company has been charging an initial rental fee of $29 plus $2.50 per hour for rental of their small trucks. After a change in pricing policy, the new fee will be $19 up front plus $3.25 per hour. After how many hours of renting the truck will the new plan be more expensive than the old plan

Answers

Answer:

14 hours

Step-by-step explanation:

Old plan :

Initial fee =. $29

Hourly fee = $2.50

New plan :

Initial fee = $19

Hourly fee = 3.25

Let number of hours = x

When new plan will be more expensive than old plan :

19 + 3.25x > 29 + 2.50x

3.25x - 2.50x > 29 - 19

0.75x > 10

x > 10 / 0.75

x > 13.3333
