In This Swimming Pool Design, Explain How To Find The Area Of The Pools Surface.

Answers

Answer 1

Answer:

8 ft × 10 ft = 80 ft

The bit at the end is a semi-circle and its diameter is 8ft, the formaula to find its circumference is (Diameter × π) = 8π but this is half a circle so

8π ÷ 2 = 4π

Now to find the area of the pool, you have to minus 4π by 80

80 - 4π = 67.4 (3 significant figures)

Maria has the following scores on exams in her social studies class: 86, 75, 97, 58, 94, and 58.

A. Find the mean, median, and mode of the scores.

B. Should Maria’s social studies teacher use the mean, median, or mode of the exam scores to convince Maria that she needs to study more regularly for her exams?

Answers

Answer:

Below in bold.

Step-by-step explanation:

Arrange the scores in ascending order:

58 58 75 86 94 97

A. The mean = (58+58 +75+ 86+ 94+ 97)/6

= 468/6

= 78.

The median = (75+ 86)/2 = 80.5.

The mode = 58.

B. She should use the mode as it is the lowest score.

Mean: 78

Explanation: the mean is the average number in a data set, meaning you have to add all of the numbers and divide by the number of values (86 + 75 + 97 + 58 + 94 + 58) / 6

Median: 80.5

Explanation: The median is the value that separates the higher half from the lower half in a data set. in this case, you have to order the numbers least to greatest and since there is an even amount of numbers, you take the two middle ones and find the average of the two. (75 + 86) / 2

Mode: 58

Explanation: the mode is the value that appears most frequently in a data set, in this case it is 58

Part B: Maria’s social studies teacher should use the mode of the exam scores to convince Maria that she needs to study my regularly for her exams because it is the lowest score

Jacob says that 1 1/8 inches is an outlier because it is the only length that does not have any dots. Is Jacob correct? Explain.

A. Jacob is correct. All of the other data values have dots, so a data value without dots is different and is therefore an outlier.

B. Jacob is not correct. An outlier is a data value that is very different than the other data values that have at least 1 dot.

C. Jacob is not correct. An outlier can lie anywhere on the line plot, and it must have exactly 1 dot.

D. Jacob is not correct. The outlier is 1 4/8 inches because the outlier is always the greatest data value.

Answers

A.Jacob is correct. The correct value is 1 1/8 inches. All of the other data values have dots, so a data value without dots is different and is therefore an outlier.

What is an Outlier?

An outlier is an observation that lies at an abnormal distance from other values in a random sample from an Experiment.

On observing the given figure length that does not have any dots is between

[tex]1 \ and\ 1\dfrac{2}{8}[/tex]

Calculatte the value between it

[tex]\dfrac{1+1\dfrac{2}{8}}{2}\\=\dfrac{\dfrac{18}{8}}{2}\\\\=\dfrac{9}{2}\\\\=1\dfrac{1}{8}[/tex]

Hence Jacob is correct. All of the other data values have dots, so a data value without dots is different and is therefore an outlier.

15% of the tickets were reserved seats that sold for $35 each. What was the total amount in sales for the $35 tickets?

Answers

Answer:

Total amount earned from the sale of 45$ reserved seats=  56,250$

Total amount accruing from the sale of 35$ seats= 26,250$

Total seats sold as general = 3000 seats

Total amount accruing from sale of general admission seats= 60,000$

Total amount garnered from sale of all the tickets= 1,42,500$

Step-by-step explanation:

Total number of seats available at the auditorium- 5000

A. 25% tickets= reserved seats

Total number of seats= 25*5000/100=1250 tickets

Cost of each seat- 45$

Total amount earned from the sale of reserved seats=  56,250$

B. 15% of the seat reserved at 35$ each

Total number of such seats reserved= 15*5000/100=750 seats

Total amount accruing from the sale of such seats= 26,250$

C. The remainder of the seats were sold as general seats

Total seats sold as general= 5000-(1250+750) = 3000 seats

D. Cost of each general admission= 20$

Total amount accruing from sale of general admission seats= Total seats*price of each

= 3000*20$= 60,000$

E. Total amount garnered from sale of all the tickets= 60,000$ + 56,250$ + 26250$

=1,42,500$

To find the area of a triangle the formula is 1/2ab

1/2*8*6= 24

1/2*8*5=20

20*2+24*2=88

An elevator is being pulled up from the ground floor to the third floor by a cable. The cable is exerting 4500 newtons of force on the elevator. According to Newton's law of action-reaction, what is the gravitational force on the elevator and the people in it, in newtons, if the elevator is not accelerating?



Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value.

Answers

Answer:

The gravitational force on the elevator = 4500N

The given parameters are;

The force applied by the elevator, F  = 4500 N

The acceleration of the elevator = Not accelerating

From Newton's third law of motion, the action of the cable force is equal to the reaction of the gravitational force on the elevator which is the weight, W and motion of the elevator as follows;

F = W + Mass of elevator × Acceleration of elevator

∴ F = W + Mass of elevator × 0 = W

F = 4500 N = W

The net force on the elevator is F - W = 0

The gravitational force on the elevator = W = 4500N.

Answer:

The gravitational force on the elevator = 4500N

The given parameters are;

The force applied by the elevator, F  = 4500 N

The acceleration of the elevator = Not accelerating

From Newton's third law of motion, the action of the cable force is equal to the reaction of the gravitational force on the elevator which is the weight, W and motion of the elevator as follows;

F = W + Mass of elevator × Acceleration of elevator

∴ F = W + Mass of elevator × 0 = W

F = 4500 N = W

The net force on the elevator is F - W = 0

The gravitational force on the elevator = W = 4500N.

Couple rules you have to know.

For angles d and e - angles opposite each other, equal each other

For angle f - you need to know d and e from previous rule. The angle of a flat line is 180 so d + e + f = 180 so f = 180- e - d

Answer:

d= 45°

e = 85°

f = 53°

Step-by-step explanation:

Given the image provided.

Solution:

we can see that d = 45, e = 82

     and 180 - (82+45) = f

                     f = 53

Find your running pace per mile, kilometer, yard or meter. Calculate the distance you can run in a given amount of time, time required to run a specific distance, or your running speed. Use this calculator to find average pace for running, biking, swimming or walking.

Step-by-step explanation:

How to calculate running pace

Divide your run time by your distance

If you ran 3 miles in 30 minutes:

30 min ÷ 3 mi = 10 minutes per mile pace

How to calculate run distance

Divide your running time by your pace

If your pace is 8 minutes per mile and you ran for 32 minutes:

32 min ÷ 8 min per mi = 4 miles

How to calculate run time

Multiply your pace by your distance

If your pace is 9.5 minutes per mile and you ran 3 miles:

9.5 min per mi × 3 mi = 28.5 minutes = 28 minutes, 30 seconds

How to calculate running speed

Divide your run distance by your run time

If you ran 2.5 miles and you ran for 20 minutes:

2.5 mi ÷ 20 min = 0.125 miles per minute
