Copy machine a copies 6o pages in 45 seconds. copy machine b copies 75 pages per minute. whixh copier copies faster, and by how much?

A is faster by 5 pages

Step-by-step explanation:

Machine A= 60 pages in 45seconds

Divide by 15

4 pages in 3 seconds

Multiply by 20

80 pages in a minute

Machine A = 80 pages or min

Machine B = 75 per min

A is faster by 5 pages

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
