An investment firm wants to create a billboard that displays an enlarged $1,000,000 bill. the actual size of the bill is 2.61 inches by 6.14 inches. if the billboard is 48 feet wide, what's the scale of the bill to the billboard? a. 1′ = 8.71″ b. 1′ = 7.81″ c. 1″ = 8.71′ d. 1″ = 7.81′

We know how wide the billboard will be. Therefore, to know how much the original image should be enlarged, you must divide the final width of the billboard between the current width of the invoice.

We know both data, then we perform the operation:

48 feet /6.14 inches = 7.81 feet / inches

Therefore the correct answer is option D. 1″ = 7.81′

For the bill to cover the billboard, the bill must be expanded by a factor of 7.81 feet long per inch long that has the original image.

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.
