a computer technician charges a flat fee of $35 to repair a computer in addition to an hourly rate of $22.50. the technician has calculated he will earn at least $215 from his next repair job. which inequality can be used to determine the number of hours, h, that the technician will work on his next job?

a
22.5h+35≥215 , with a solution of h≥8

b
22.5h+35> 215 , with a solution of h> 8

c
35h+22.5≥215 , with a solution of h≥5.5

d
35h+22.5> 215 , with a solution of h> 5.5

The base of a triangle exceeds the height by 9 inches. if the area is 180 square inches, find the length of the base and the height of the triangle.

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.

Ariana starts with 100 milligrams of a radioactive substance. the amount of the substance decreases by 20% each week for a number of weeks, w. the expression 100(1−0.2)w finds the amount of radioactive substance remaining after w weeks. which statement about this expression is true? a) it is the difference between the initial amount and the percent decrease. b) it is the difference between the initial amount and the decay factor after w weeks. c) it is the initial amount raised to the decay factor after w weeks. d) it is the product of the initial amount and the decay factor after w weeks.
