4 0

Step-by-step explanation:

5 computers = $140

10 computers = $200

15 computers = $260

Common difference = $60 for every 5 computer, $12 for 1 computer.

let cost of x no of computers be c.

forming an equation,

c = (x - 5) x 12 + 140

hence, to ship 84 computer,

c = (84 - 5) x 12 + 140

c = 1088

thus answer is option B.

A scale model of a building is 3 inches tall. If the building is 90 feet tall, find the scale of the model.
olganol [36]

The scale model of a building 3 inches tall if the building is 90 feet tall is 2:5

<h3>Scaling of measurement</h3>

Scaling is the way of enlarging or reducing the image of an object.

Given scale model of a building is 3 inches, if the building is 90feet tall, to write the scale;

Convert both measures to same units

Since 1 feet. = 12 in

90 feet = 90/12 in = 7.5 in

Take the ratio

3 : 7.5 = 30: 75

Reduce to lowest term

30: 75 = 2 : 5

Hence the scale model of a building 3 inches tall if the building is 90 feet tall is 2:5
