The length of a football field is 120 yd. the width of the football field is 50 yd. which is the correct unit of measurement to use when figuring out how much rope is needed to surround the field?
a. yd
b. yd squared
c. yd cubed

The answer is:  [A]:  "yd" .

Note:  Since we are referring to "how much rope is needed to surround the           field" ;  we are referring to the "perimeter";  or adding up the length of all         the sides.  So there will be no "squared units" (choice B — which would         refer to the "area"; and no "cubic units" (choice C - would would refer to         the volume of a 3-dimensional solid (e.g. rectangular prism; since we only       have two dimensions {a football field; with only a length and width (no             height) } ; and as mentioned; we are referring to the "perimeter";  which is       the sum of the lengths of all sides.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

when multiplying or dividing by a negative on both sides you have to flip the inequality sign. this rule only applies to multiplying or dividing by a negative number in inequality equations. this rule is really important.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
