A rectangle on a coordinate plane has vertices at (7, 5), (-7, 5), (-7, - 2), and (7, - 2). What is the perimeter of the rectangle?

At Avery Middle School, 273 students responded to a survey asking whether a Bulldog, a Lion, or a Tiger should be the new school mascot. Four times as many students chose Bulldog as chose Tiger. Twice as many students chose Lion as chose Tiger. How many students chose Lion?

Which list of numbers is ordered from least to greatest?

A. 6 3/4,6.57,-6.53,-6 1/4

B. - 6.53,-6 1/4,6.57,6 3/4

C. 6 3/4,6.57,-6 1/4,-6.53

D. - 6 1/4,-6.53,6.57,6 3/4

Koen Joyce · Answer 1

1) Dimensions of rectangle are 14 and 7. Perimeter is:

2 * (14+7) = 42.

2) Let the number of students who chose Tiger be x.

Number of students who chose Bulldog is 4*x.

Number of students who chose Lion is 2*x.

7x = 273 - > x=273/7=39.

Answer is 2*x=78.

3) The answer is B).

A and C aren't answers because they start with positive and end with negative numbers and D isn't answer because - 6 1/4 is greater than - 6,53.
