A school is building a rectangular stage for its chorus. The stage must have a width of 4 feet. The area of the stage must be at most 24 square feet. (These are rules of the local fire department.) Write an inequality that describes the possible lengths (in feet) of the stage.

Length ≥ 6 feet

Step-by-step explanation:

The area of a rectangle= length × width

In this case, the width is 4 feet and the area of the stage must be at most 24 square feet.

The inequality that describes the possible lengths (in feet) of the stage would be:

Length × Width ≥ 24

Length × 4 ≥ 24

Length ≥ 24/4

Length ≥ 6

Therefore, the length must be at most 6 feet.

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

three-fourths of an hour

36÷48=0.75

0.75=
