A golf team's 6 members had the scores below in their most recent tournament:
70,\,72,\,74,\,76,\,80,\,114
PROBLEM A
Calculate the mean score.
mean =

Answers

Answer 1

Answer:

81

Step-by-step explanation:

To get the mean score, we have to add all their scores and divide the result by the number of members in the team.

(70+72+74+76+80+114) ÷ 6 = 486 ÷ 6 = 81

So, the answer is 81.

Pamela's parakeet is currently in a rectangular bird cage that has a length of 3 feet, a width of 2 feet, and a height of 3 feet. Since the parakeet has gotten larger, Pamela is looking to buy a new rectangular bird cage. She wants the new cage to have a volume that is 4 times the volume of the parakeet's current cage. If Pamela wants to keep the length of the new cage the same, how must the other dimensions change?

Answers

Answer:

The volume of existing cage = length x widht x height = 3 x 2 x 3 = 18 cubic ft

Now she wants cage with volume four times of this cage

New Volume = V1 = 18 x 4 = 72 cubic ft

Keeping length same = 3 ft

Length x width x height = V1

3 x Width x height = 72

Width x height = 72 /3

Width x height = 24

Now multiple of 24 must be the width and height.

Taking width = 6 ft and height = 4 ft, we will get our answer

Proof:

Length x width x height = V1

3 x 6 x 4 = 72

A car and a truck left Washington, DC traveling in opposite directions. The car
traveled 19 miles
per hour faster than the truck, and at the end of 8 hours they were
1048 miles apart. What was the average speed of each vehicle?

Answers

Answer:

The speed of the car is 75 mph.

The speed of the truck is 56 mph.

Step-by-step explanation:

Call the speed of the truck (x) miles per hour. As per the given information, the car is (19) miles per hour faster. Thus, one can form expressions to represent the speeds of the vehicles.

car = ( x + 19 ) mph

truck = ( x ) mph

Using the formula, ( (speed) * (time) = (distance) ), one can say that the speed of the car, times the time it took plus the speed of the truck times the time will equal the distance between the two vehicles:

(( car speed )( time )) + (( truck speed )( time )) = ( distance between vehicles )

Substitute,

( ( x + 19 ) ( 8 ) ) + ( ( x ) ( 8 ) ) = 1048

Simplify,

8x + 152 + 8x = 1048

16x + 152 = 1048

       -152     -152

16x = 896

/16     /16

x = 56

Add (19) to find the speed of the car:

truck speed + 19

= 56 + 19

= 75

The speed of the car is 75 mph.

The speed of the truck is 56 mph.

Answer:

The truck traveled at 81

mph. The car traveled at 100

mph.

Suppose two rectangles are similar with a scale factor of 2. What is the ratio of thier areas? Explain.

Answers

Answer:

4

Step-by-step explanation:

From the question,

Since both rectangle has a scale factor of 2,

L₁/L₂ = 2

Where L₁ and L₂ are the length of the first and second rectangle respectively

L₁ = 2L₂................ Equation 1

Also,

W₁/W₂ = 2............ Equation 2

Where W₁ and W₂ are the Width of the first and second rectangle respectively

W₁ = 2W₂

Area of a rectangle = Length × width

Area of first rectangle = L₁×W₁ = 2L₂×2W₂ = 4L₂W₂

Area of second rectangle = L₂×W₂= L₂W₂

The ratio of area = Area of the first rectangle/Area of the second rectangle = 4L₂W₂/L₂W₂ = 4

A prop for the theater club's play is constructed as a cone topped with a half-sphere. What is the volume of
the prop? Round your answer to the nearest tenth of a cubic inch. Use 3.14 to approximate pi. Complete
sentences

Answers

Answer:

Volume of the prop = 706.5 in³

Step-by-step explanation:

Volume of the prop given in the picture = Volume of hemisphere + Volume of the cone

Volume of the hemisphere = [tex]\frac{2}{3}\pi r^{3}[/tex]

where 'r' = radius of the hemisphere

For r = 5 in,

Volume of the hemisphere = [tex]\frac{2}{3}(3.14)(5)^{3}[/tex]

                                             = 261.67 in³

Volume of a cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]

Here r = radius of the circular base

h = height of the cone

For 'r' = 5 in and h  17 in.

Volume of the cone = [tex]\frac{1}{3}(3.14)(5)^2(17)[/tex]

                                  = 444.83 in³

Volume of the prop = 261.67 + 444.83

                                 = 706.5 in³

Recreation that uses the large muscles of the body is sometimes referred to as _____.A. extrinsic recreationB. physical recreationC. motor skill recreationD. sedentary recreationNO LINKS! A local community college professor decided to fight back. "The price of books for our students is justgetting higher and higher and, combined with the rising cost of tuition, it's killing these kids," said PeterJason, Ph.D. "Remember, students are one of the poorest groups of people in America. Almost half of themhave at least one part-time job. In fact, one of my students has three jobs. She is a part-time sales clerk at aclothing store three days a week, then works three evenings a week as a pizza cook, and on weekends shedoes manicures at a beauty salon. And she still manages to have a high GPA and go to school full-time."Textbook prices are traditionally high. Adding to that problem, many college instructors changetextbooks year after year; they either upgrade to a new edition or switch to an entirely different textbook.This further hurts students because if an instructor no longer uses a particular textbook, that book has noresale value.Dr. Jason decided to make life a little easier and a lot cheaper for his students by writing his own bookon public speaking. "Many books have an increased price because of bells and whistles: CD-ROMs, lots ofcolor photographs, and lots of graphics. I talked to my students, and many of them, like me, prefer to keepthings simple. So, during a sabbatical a few years ago, I wrote my own textbook. I made sure that it wasn'tlong-winded. I called it Successful Public Speaking: How To Be Brief, Concise, and to the Point."Compared to most other public speaking primers, mine is half the number of pages, and one-third theprice. That is, $30 instead of $90. Plus, it is published in a three-ring binder format. So, when I wrote asecond edition last year, students only had to buy the 35 new pages and delete 35 of the original pages. Foronly $7.00, they had upgraded to the new edition. I've had great feedback from my students about this looseleaf concept.
