The elevation of the basement floor in a building is -14 ft. the elevation of the roof is 36 feet. what is the distance from the basement floor to the roof? a) -50 ft b) -24 ft c) 24 ft d) 50 ft

Hello there!

if you want to know the distance between two points, you need to calculate the difference between them.

if the basement floor is at -14 ft, and the roof is at 36 ft, then the distance between the basement floor and the roof is: 36 ft - (-14)ft = 36ft + 14ft = 50 ft

You can see that we obtained a positive number, this is because we define positive to the upward direction, so if you are in the basement, you need to do 50 ft upwards to reach the roof.

then the correct answer is D.

e) none of the above because the measure of angle cba is 101°

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
