*i will mark u branliest and give 40 points if u answer all three*

1.) the scale drawing of an artist's work has a scale of 1 inch = 18 inches. the scale drawing is 5 inches and 6 inches long. find the size if the original work.

2.) the scale for a drawing of a barn is 1/2 inch = 4 feet. if a pole in the drawing measures inches, how tall is the actual pole?

3.) monica made a scale model of a helicopter. if the scale is 1 inch = 3 feet, and the model is inches tall, how tall is the actual helicopter?

Step-by-step explanation:

1. 18(5)=90           18(6)=108

90*108= 9720

Her size of the original work was 9720 inches.

2. 1/2+1/2= 1      1/2=4 ft

The pole is 8 feet tall

3. 3 feet

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
