1. 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

3. maya is playing a game in which a set of cards is laid out, face down, in a grid pattern. each card has a mathematical expression written on its face. a player flips over one card and then a second. if the values represented on both card faces are equal, the player scores a point. maya flips over a card showing the expression below. -6over7
which expression on maya's second card will allow her to score a point?
a. –(–6/7)
b. 6/-7
c. 7/-6
d. -6/-7

The inequality can be used to determine the number of hours, h, that the technician will work on his next job is 22.5h + 35 ≥ 215 , with a solution of h ≥ 8

1.

flat fee = $35

hourly rate = $22.50

Total earnings = atleast $215

number of hours = h

The inequality:

35 + 22.50h ≥ 215

22.50h ≥ 215 - 35

22.50h ≥ 180

h ≥ 180 / 22.50

h ≥ 8

2.

flat fee = $3

cost per mile = $1.80

Total amount = atleast $25

number of miles = m

The inequality:

3 + 1.80m ≥ 25

1.80m ≥ 25 - 3

1.80m ≥ 22

m ≥ 22/1.80

m ≥ 12.2

A. $3 + 1.80m ≥ $25

3.

-6 over 7

= -6/7

Therefore, the equivalent value to -6/7 is 6/-7

1.Multiply the hourly rate by the number of hours worked ( 22.5h) add that to the flat fee ( 22.5h +35) and that needs to be equal to or greater than what he expects to make:

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

2.Same method as number 1:

C.$3 + 1.80m ≤ $25

3.Each fraction would need 1 negative sign and have the same numerator and denominator, so the answer would be B.6/-7

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
