The height of each story in a hotel is feet. the height is measured from the ceiling to the floor. the hotel has 2 underground levels that are used as banquet halls. stephen is a waiter who works two levels below ground. at what elevation are stephen’s feet? assume the ground level of the hotel is at 0 feet.

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19

i believe the correct answer is b.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
