To win a trivia game, Nevan must score 90 points. Each correct answer is worth 1 3/4, and each incorrect answer is -1 1/4, if he

Archy [21]

Answer:

Nevan does not win

He scored 74 points

Step-by-step explanation:

First, find how many points he gets from 58 correct questions:

Multiply 1 3/4 by 58:

58(1.75)

= 101.5

Then, find how many points he loses from 22 incorrect questions:

Multiply -1 1/4 by 22:

22(-1.25)

= -27.5

Then, subtract 27.5 from 101.5 to find how many points he scored:

101.5 - 27.5

= 74

Since he needed 90 points to win, he did not win because he only got 74.

You need to order carpet for a room that has a length that is twice its width. if the area of the room is 128 ft 2, find the wid

Setler [38]

A = L * W
L = 2W
A = 128

128 = 2W * W
128 = 2W^2
128/2 = W^2
64 = W^2
sqrt 64 = W
8 = W <== width

L = 2W
L = 2(8)
L = 16 <== length
