Keith has a package of 75 marbles.He gave an equal number of marbles to each of his 8 friends. How many marbles will be left over?

Answers

Answer:

9

Step-by-step explanation:

The number of marble left if Keith has a package of 75 marbles, He gave an equal number of marbles to each of his 8 friends, is 3.

What is division?

Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups.

When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers. For instance, 4 2 = 2. As a multiplication fact, this can be expressed as 2 + 2 = 4.

Given:

Keith has a package of 75 marbles, He gave an equal number of marbles to each of his 8 friends,

Calculate the number of marble left as shown below,

The number of marble left = Reminder of (total number of marble / 8)

The number of marble left = Reminder of(75 / 8)

The number of marble left = 3

Thus, the number of marble left is 3.

a coach buys a uniform and a soccer ball for each of 12 players on the team each soccer ball cost $15 the coach spends the $432 for uniforms and soccer balls how much does each uniform cost

Answers

Answer:

$21

Step-by-step explanation:

12 times 50 is 180. 432 minus 180 is 252. 252 divided by 12 is 21.

Hello, I hope you are having a great day, your question, a coach buys a uniform and a soccer ball for each of 12 players on the team each soccer ball cost $15 the coach spends the $432 for uniforms and soccer balls how much does each uniform cost Okay so we know we got 12 players on each team that cost $15 for a soccer ball so we times that by 12 = $180 now we take away that from $432 - $180 = 252$ then divide that 12 = 21 so the uniform cost $21 all together.

Answers

If salary average of 4 players is making $200,000/yr, what's the total payroll?  It should be $200K x 4 or $800,000.

Now if you add in that 5th player at $400,000 what is the total payroll of all 5 players?  It should be $800,000 + $400,000 = 1,200,000.  From there you can find the average of the 5 players by dividing!

Answers

Answer:

$19.60

Step-by-step explanation:

Given data

number of pages= 136 pages

number of copies = 19 copies

Hence 19 copies make a total of = 136*19

=2584 pages

hence if 500 pages cost $3.80

  then   2584 pages will cost x

cross multiply

500x= 2584*3.8

500x=9819.2

Divide both sides by 500

x= 9819.2/500

x= 19.6384

x=$19.60

Patient B: 59
92
60

95 70
Find the mean pulse rate for each patient and the corresponding range.

Answers

Answer:

1a. Mean pulse rate for A = 60.5

1b. Range for A = 62

2a. Mean pulse rate for B = 73

2b. Range for B = 45

Step-by-step explanation:

1a. Determination of the mean pulse for patient A.

Data => 17, 16, 70, 69, 70, 75, 78, 70, 71, 69

Mean =?

The mean pulse rate for patient A can be obtained as follow:

Summation of data = 17 + 16 + 70 + 69 + 70 + 75 + 78 + 70 + 71 + 69

Summation of data = 605

Number of data = 10

Mean = summation of data / number of data

Mean = 605 / 10

Mean pulse rate for A = 60.5

1b. Determination of the range for patient A

Data => 17, 16, 70, 69, 70, 75, 78, 70, 71, 69

Range =?

Range = Highest – Lowest

Highest = 78

Lowest = 16

Range = Highest – Lowest

Range = 78 – 16

Range for A = 62

2a. Determination of the mean pulse for patient A.

Data => 59, 92, 60, 80, 71, 65, 50, 88, 95, 70

Mean =?

The mean pulse rate for patient B can be obtained as follow:

Summation of data = 59 + 92 + 60 + 80 + 71 + 65 + 50 + 88 + 95 + 70

Summation of data = 730

Number of data = 10

Mean = summation of data / number of data

Mean = 730 / 10

Mean pulse rate for B = 73

2b. Determination of the mean pulse for patient B.

Data => 59, 92, 60, 80, 71, 65, 50, 88, 95, 70

Range =?

Range = Highest – Lowest

Highest = 95

Lowest = 50

Range = Highest – Lowest

Range = 95 – 50

Range for B = 45
