Janice is building shelving for her office . each shelf will be 3 feet 9" in length . she can buy boards that are 13 & a half feet long. how many boards does seh need to buy to make 30 shelves

She need to buy 8 boards.

Step-by-step explanation:

Given:

Number of shelves = 30

Length of each shelf = 3 ft 9 inches

Length of each board she can buy =

Now, using Unitary method, finding the total length of the 30 shelves.

Length of 1 shelf = 3 ft 9 in =

∴ Length of 30 shelves =

Now, the number of boards that she can buy is given by dividing the total length of the shelves and length of each board. Thus,

Number of boards =

Number of boards =

Therefore, the number of boards she can buy are 8.

step-by-step explanation:

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
