If you jog 8 times around a track that is 600 meters long, how many kilometers have you covered?

Answers

Answer:

0.6 km

Step-by-step explanation:

If If you jog 8 times around a track that is 600 meters long, then 4.8 kilometers you have covered

What is Unit of Measurement?

A Unit of measure is the actual unit in which the associated values are measured.

Given,

If you jog 8 times around a track that is 600 meters long,

We need to find how many kilometers you have covered.

8 times around a track that is 600

It means we have to multiply eight with six hundred.

8×600

=4800

We know that 1 km is 1000 m

So divide 4800 by 1000 to find in kilometers

4800/1000=4.8km

Hence If you jog 8 times around a track that is 600 meters long, Then 4.8 Kilometers you have covered.

x = 25°

y = 25°

Step-by-step explanation:

✔️(x + 35)° + 30° + 90° = 180° (sum of triangle)

x + 35 + 30 + 90 = 180

Add like terms

x + 155 = 180

x + 155 - 155 = 180 - 155

x = 25°

✔️(y + 30)° + 35° + 90° = 180° (sum of triangles)

y + 155 = 180

y = 180 - 155

y = 25°

Answers

Step-by-step explanation:

use formula y-y1=m(x-x1)

(4,15) = (x1,y1)
(9,20)=(x2,y2)

m is the slope which you don’t have but you can find by doing (y2-y1)/(x2-x1)
m=(20-15)/(9-4)
m=5/5
m=1

y-y1=m(x-x1)
y-15=1(x-4)
y-15=x-4 |+15 to both sides

2. The German Shepard actually weighs 28 pounds. Lisa thought the
dog weighed 44 pounds. What is the percent error?

Answers

Answer:

Lisa's percentage of error regarding the weight of the dog was 57.14%.

Step-by-step explanation:

Given that the German Shepard actually weighs 28 pounds, but Lisa thought the dog weighed 44 pounds, to determine what is the percent error the following calculation must be performed:

28 = 100

44 = X

(44 x 100) / 28 = X

4,400 / 28 = X

157.14 = X

157.14 - 100 = 57.14

Thus, Lisa's percentage of error regarding the weight of the dog was 57.14%.

Step-by-step explanation:

Given:

DC = 1

CE = x + 4

AB = 11

BE = x + 1

Required:

Value of x

Solution:

(DC + CE) × CE = (AB + BE) × BE

(1 + x + 4) × (x + 4) = (11 + x + 1) × (x + 1)

(x + 5) × (x + 4) = (x + 12) × (x + 1)

x² + 4x + 5x + 20 = x² + x + 12x + 12 (distributive property)

x² + 9x + 20 = x² + 13x + 12

Collect like terms

x² - x² + 9x - 13x = - 20 + 12

-4x = -8

Divide both sides by -4

x = -8/-4

x = 2

A towns population went from 40,000 to 50,000. What was the percent of change in the population?

Answers

Answer:

The percent of change in the population was of 25%.

Step-by-step explanation:

Percent change:

The percent change is given by the change multiplied by 100, and divided by the initial value.

A towns population went from 40,000 to 50,000.

Change: 50000 - 40000 = 10000

Initial value: 40000

10000*100/40000 = 25%

The percent of change in the population was of 25%.

Scoring is done by eleven (11) international judges. They each submit a score in the range from 0 to 100. The highest and lowest scores are not counted. The remaining nine (9) scores are averaged and the median value is also determined. The participating team with the highest average score wins. In case of a tie, the highest median score, among the teams that are tied for first place, determines the winner.Scoring data is be provided in the form of a text file. The scoring data for each team consists of two lines; the first line contains the team name; the second line contains the eleven (11) scores. You will not know ahead of time how many teams will participant. Your program will:Prompt the user for the name and location of the scoring data file.Process the sets of records in the file.Read and store the team name in a string variable.Read and store the scores in an array.Display the team name followed by the complete set of scores on the next line.Calculate and display to two decimal places the average of the nine qualifying scores, dropping the lowest and highest scores.Determine and display the median value among the qualifying scores.Display the count of the number of participating teams.Display the winning team name and their average score.

The Angry Piranhas and the Tiger Sharks both had an average score of 50.0. The tiger sharks had a median value of 55.0, making them the winners of the competition.You will define and use at least one function in your solution. As a suggestion, you should consider calling a function that sorts the array of judges score values into ascending order (lowest to highest). The advantage of doing this is that after being sorted, the lowest value is the first entry in your array and the highest value is the last entry in your array.The average or arithmetic mean is a measure of central tendency. It is a single value that is intended to represent the collection of values. For this problem, you will only use nine of the values to determine the average. You will not include the highest score and the lowest score.The median is another measure of central tendency. The median is often referred to as the middle value. In a set of values, half the values are less than the median and the other half are greater than the median. In a sorted array of five elements, the median is the third element. There are two values that are less then it and there are two values that are greater than it. In a sorted array of six values, the median is the simple average of the third and fourth values. In some cases, the median is a better representative value than the average.You are encouraged to read the article entitled "Mixing getline with cin".To receive full credit for this programming assignment, you must:Use the correct file name.Submit a program that executes correctly.Interact effectively with the user.Grading Guideline:Correctly name the file submitted.Create a comment containing the students full name.Document the program with other meaningful comments.
