On a floor plan drawn at a scale of 1:100, the area of a rectangular room is 30

Mathematics

Troyanec [42]3 years ago

Assume that the dimensions of the room in the plan are a (width ) by b (length),

such that a*b=30.

Since the scale is 1:100, a represents 100a, and b represents 100b.

So the actual dimensions are 100a by 100b.

The area is 100a*100b=a*b*10,000=30*10,000=300,000 (square units)



Answer:  300,000 (square units)

A triangle is a figure with three sides.

Which can be re-written in the if-then form as If  the figure is a triangle then it has three sides.

The elevator has a MAX capacity of 8 people. This means that only 8 or less people can be on the elevator at a time. If c = # of people then c must be less than or equal to 8 as the elevator has a max capacity of 8 people. Hence the mathematical statement would be c ≤ 8

When the inequality sign is facing the "y" the solutions to the set can be found above the line. This could also be checked by graphing.
