Answer:

Claire is standing at a distance of 485.45 meters to Chloe.

Step-by-step explanation:

The track is a circular with a radius of 100 meters.

The total length of the circular track = length of the circumference of a circle

But, length of the circumference of a circle = 2[tex]\pi[/tex]r

So that,

total length of the circular track = 2[tex]\pi[/tex]r

                                            = 2 × [tex]\frac{22}{7}[/tex] × 100

                                           = 628.57

The total length of the circular track is 628.57 meters.

Thus,

the distance of Claire to Chloe = total length of the circular track - distance of Chloe to Claire

                                                             =  628.57 - 143.12

                                                             = 485.45

This means that Claire is standing at a distance of 485.45 meters to Chloe.

Answer:

b) observing every person walking down Main Street at 5 p.m. one evening to determine the percentage of people who wear glasses.

d) taking a poll in the lunch room (where all students currently have to eat lunch) to determine the number of students who want to be able to leave campus during lunch.

Step-by-step explanation:

These are the two options that are most likely to give you a sample that fairly represents the population. In the first case, the sample that you obtain is likely to be a good representation because Main Street is a road where a great variety of people walk. Moreover, 5 pm is also a time that will allow you to see  a great number of different people. The second answer will also give you a good sample, as the poll would include all students in the lunch room, which is all students in the school (the whole population).

Bus A and Bus B leave the bus depot at 7 am. At 10:20 AM are they both back at the bus depot together.

Given:

Bus A and Bus B will both be back at the depot at the same time at 10:20am.

To solve the problem, we need to determine when both Bus A and Bus B will be back at the depot at the same time. Since Bus A takes 25 minutes to complete its route and Bus B takes 40 minutes, we need to find the common multiple of these two numbers. The smallest common multiple of 25 and 40 is 200. This means that both buses will be back at the depot at the same time after 200 minutes.

Since the buses leave the depot at 7:00 am, we add 200 minutes (or 3 hours and 20 minutes) to this time. Therefore, it's at 10:20 am that both buses are back at the depot at the same time.

The volume of gas is 80 cubic feet at the same temperature when the pressure is 8 pounds.

Step-by-step explanation:

The given is,

                Volume of gas is 120 cubic feet under 6 pounds of pressure.

                Volume of gas varies inversely as the pressure.

                Pressure is 8 pounds

Step:1

               From the given,

               Volume of gas varies inversely as the pressure,

                                  [tex]P_{gas}[/tex]  ∝  [tex]\frac{1}{V_{gas} }[/tex].......................................(1)

               Ratio of volume to pressure of gas is,

                                                = [tex]\frac{120}{6}[/tex] = 20

Step:2

              Pressure of gas is increased 6 to 8 pounds,

              Change in pressure = 8 - 6 = 2 pounds

              Change in volume = Ratio × change in pressure

                                              = 20 × 2 = 40 cubic feet

Step:3

             From the equation (1),

             The pressure is increased, the volume of gas is reduced.

             Volume of gas at pressure of 8 pounds = 120 - 40

                                                                                = 80 cubic feet

Result:

             The volume of gas is 80 cubic feet at the same temperature when the pressure is 8 pounds.

Answer:

D) vertical asymptotes x = −4, 2

Step-by-step explanation:

First you factor the denominator: x^2 +2x−8

Find factors of -8(c) that add together to give 2(b): 4 and -2

Rewrite the equation: x^2+4x-2x-8

Factor out common variables: x(x+4)-2(x+4)

Group the things inside and outside the parentheses together: (x-2)(x+4)

Solve: x-2=0 so x=2 and x+4=0 so x=-4

Answer:

D) vertical asymptotes x = −4, 2

Step-by-step explanation:

x² + 2x - 8 = 0

x² + 4x - 2x - 8 = 0

x(x + 4) - 2(x + 4) = 0

(x + 4)(x - 2) = 0

x = 2, -4

Answer:

The number of fries and shakes sold are 70 and 35 respectively.

Step-by-step explanation:

The number of fries sold can be denoted by x.

The number of shakes sold can be denoted by y.

The equation representing the total number of items sold is:

x + y = 105...(i)

The cost fries is, $2.

The cost of shakes is, $3.

The equation representing the total money earned is:

2x + 3y = 245...(ii)

Solve equations (i) and (ii) simultaneously as follows:

Multiply equation (i) by 3 and subtract:

3x + 3y = 315

2x + 3y = 245

(-)     (-)      (-)

___________

x = 70

Compute the value of y as follows:

x + y = 105

70 + y = 105

y = 105 - 70

y = 35

Thus, the number of fries and shakes sold are 70 and 35 respectively.

  T(t) = 3sin((t-5)π/30)

Step-by-step explanation:

5 minutes after Thomas ties it on, the torque is zero and increasing. So, the sine function is shifted right 5 minutes. The maximum value is 3, so that is the multiplier of the sine function. The period is 60 minutes, so the coefficient of t is (2π/60) = π/30. The function you want is ...

  T(t) = 3sin((t-5)π/30)

Answer:

9 in

Step-by-step explanation:

The missing length of the right angle triangle is approximately 12 in.

The missing length of the right-angle triangle can be found using the Pythagorean theorem. The theorem states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other two sides. In this case, the length of one side of the triangle is 5.6 in and the length of the other side is 10.6 in. Let's substitute these values into the formula:

a² + b² = c²

(5.6 in)² + (10.6 in)² = c²

31.36 in² + 112.36 in² = c²

143.72 in² = c²

Now, we can take the square root of both sides to find the length of the hypotenuse:

c = √143.72 in² ≈ 12 in

Therefore, the missing length of the right angle triangle is approximately 12 in.

Answer:

$1,725.39

Step-by-step explanation:

-Take 1 year =365 days.

#We calculate the effective interest rate for 7% compounded daily;

[tex]i_m=(1+i/m)^m-1\\\\=(1+0.07/365)^{365}-1\\\\=0.072501[/tex]

#We now use this rate to calculate the compounded amount after two years:

[tex]A=P(1+i_m)^n\\\\=1500(1.072501)^2\\\\=1725.39[/tex]

Hence, the  balance after 2 years $1,725.39

To find the balance after 2 years with daily compounded interest, the formula [tex]A = P(1 + r/n)^(nt)[/tex] is used, with a principal of $1500, an annual rate of 7%, and n being 365. After calculations, the final balance would be approximately $1717.40.

To calculate the balance after 2 years when the interest is compounded daily, we can use the formula for compound interest: A = P(1 + r/n)nt, where:

In your case, you deposit $1500 in an account that pays 7% annual interest. Since the interest is compounded daily, we will use 365 for n. Here's your calculation:

After doing the math, your compounded balance after 2 years will be approximately:

A = 1500(1 + 0.07/365)730

A ≈ $1500 * 1.14493150684931506849

A ≈ $1717.40

This means that after 2 years, you will have approximately $1717.40.

The grapes have a weight of 50 pounds

Step-by-step explanation:

To calculate the weight of the grapes, we proceed as follows;

Let's categorize the skin, fiber as solids

At first, we had 1% solids and 99% water.

This means 99 pounds of water and 1 pound of solid

It must be known that the 1% solid remains the same after drying and what we have lost simply is the water,

This means that 2% of the total weight is now same 1 pound of solid after drying

Mathematically, this means

2/100 * new total weight = 1 pound

New total weight = 1 pound × 100/2 = 50 pounds

1 player scores 58 points per game,

1 player scores 14 points per game,

The rest(10) of the players score 0 points per game.

The Scores are: 0,0,0,0,0,0,0,0,0,0,14,58

[tex]Mean=\frac{0+0+0+0+0+0+0+0+0+0+14+58}{12} \\Mean=6\\Median=\frac{0+0}{2}=0[/tex]

Dartmouth College

4 players score 5 points per game,

4 players score 6 points per game,

4 players score 7 points per game.

The Scores are: 5,5,5,5,6,6,6,6,7,7,7,7

[tex]Mean=\frac{5+5+5+5+6+6+6+6+7+7+7+7}{12} \\Mean=6\\Median=\frac{6+6}{2}=6[/tex]

The following applies:

(B) At Maryland, the mean number of points per player per game is greater than the median number of points per player per game.

(D)The mean number of points per player per game is the same at all 3 schools.

In college basketball, the mean and median number of points per player per game can be different depending on the scoring distribution of the team. At Dartmouth, the mean is greater than the median due to players scoring different points. At Maryland, the mean is also greater than the median due to a few players scoring higher points. The median and mean can vary across different schools and teams.

Choice A: At Dartmouth, the mean number of points per player per game is greater than the median number of points per player per game. The mean is calculated by summing up all the scores and dividing by the total number of players, while the median is the middle value when the scores are arranged in increasing order. With players scoring different points per game at Dartmouth, there will be players scoring more than the mean, pulling the mean up and making it greater than the median.

Choice B: At Maryland, the mean number of points per player per game is greater than the median number of points per player per game. With only a few players scoring points other than 0, these outlier scores will cause the mean to be greater than the median.

Choice C: The median number of points per player per game can be different at different schools. In the case of Dartmouth, the median could be greater than the mean due to a large number of players scoring the same lower points per game. In the case of Maryland, with a few players scoring higher points, the median could be lower than the mean.

Choice D: The mean number of points per player per game can be different at different schools, as explained in Choices A and B.
