Aclassroom is 20 feet long. the office is 82% longer than the classroom. how long is the office?

The length of the office is  36.4 ft

Step-by-step explanation:

The length of the classroom  =  20 ft long

The length of the office =  20 ft + 82% of the classroom length

Now, 82 % of classroom length  =  82 % of 20 ft

⇒

or, 82% of 20 ft = 16.4 ft

⇒The length of the office  = 20 ft + 16.4 ft  = 36.4 ft

Hence, the length of the office =  36.4 ft

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
