You have been asked to build a scale model of a restaurant out of bottle caps. the restaurant is 20 feet tall. your scale is 2.4 cm: 1 foot. a bottle cap is 1.2 cm tall. about how many bottle caps tall will your model be?

Step-by-step explanation:

we know that

The scale is

That means

2.4 cm in the model represent 1 foot in the real

In this problem

The restaurant is 20 feet tall

Find the height of the model

Multiply the actual height of the restaurant by the scale 2.4

A bottle cap is 1.2 cm tall

To find out the number of bottle caps divide the height of the model by 1.2

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
