To start, let x represent the width and x+100 represent the length. Since the perimeter of a figure is the sum of all the measurements of the side which can be represented by (x+100)+(x+100)+x+x and since you know your perimeter is 1220, you can set the expression equal to 1220. This would look like this:
(x+100)+(x+100)+x+x=1220
Once you have done that, combine any like terms (combine terms with the same variables and raised to the same power together) which would simplify to this:
4x+200=1220
Now that you have your like terms simplified, subtract 200 from both sides to get 4x=1020 and finally, to solve for x, or find the width, divide both sides by 4 to get x=255.
Now that you have your width, now you must find your length as the question asks to find the dimensions of the rectangular field. To find the length, add 100 to the width, 255 since according to the information given, the length is 100 more than the width. When you add 100 to 255, you should get that your length is 355.
Now that you have your length and width, you can conclude that the dimensions of the field is 255 by 355 feet, which is your answer :)
Use a unit rate! You can use the rate assignments/hour, meaning how many assignments will you do every hour. This can be written as 8/5 (assignments/hours), or 8/6 (depending on how many hours you give yourself. If you wanted to simplify. you could divide the fractions.
8/5 would become 1.6 (1.6 assignments per hour)
8/6 would become 4/3 (4/3 assignments per hour)

The best and most correct answer among the choices provided by the question is the second choice. <span>A rotation is a movement of a plane about a fixed point so that every ray on the original figure has the same length as every corresponding ray on the image.</span>I hope my answer has come to your help. God bless and have a nice day ahead!
Student 3 is correct. This is because you can distribute 3. You would do 3x6m, or 18m, and you can do 3x3, or 9. This means that Student 3 is correct. Since m is not defined as an integer, it can’t be any of the other choices.
Answer:
