The height of each story in a hotel is 11 1/2 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.

Stephen is at -23 feet below the ground level.

Step-by-step explanation:

Height of each story in a hotel is given as feet or 11.5 feet.

Hotel has 2 underground levels having same height of each level.

Total height of underground levels = 2 × 11.5 = 23 feet

Since ground level of the hotel is assumed to be at 0 feet.

Below this level all elevations will be with negative notation.

Therefore, Stephen will be working at the elevation = 0 - 23 = -23 feet

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
