Henry just got a job at the mall. His job pays an hourly rate of $10.25.

nadezda [96]

Answer:

A. He will have to work 40 hours to buy the headphones

B. 1200 ≤ 10.25x ≤ 2000 where x is # of hrs worked

He can work anywhere between 118 and 196 hours.

Step-by-step explanation:

A. Divide 399.95 by 10.25 to get 39.01 hours. But since you cant work 0.01 of an hour, you have to round up to the next hour

B. You want to make more than or equal to 1200, so put that in the inequality. You want to make less or equal to 2000, so you put that in the inequality. In the middle, you put 10.25 an hour multiplied by the number of hours, which is a variable.

To solve, I made 10.25x = 1200, and x equaled 117.07, which rounds up to 118 hours because you cant work a 0.07 of an hour. 118 hours is the low number of the spectrum.

To solve for the highest number on the spectrum, you do 10.25x = 2000, and x equals 195.12, but since you cant work 0.12 of an hour, it rounds up to 196 hours.

Secant jkl and jmn are drawn to circle o from an external point ,j. if jk=8,lk=4 and jm=6 what is the length of jn answer

Archy [21]

See the picture attached to better understand the problem

we know that
If two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.
so
jl*jk=jn*jm------> jn=jl*jk/jm

we have
jk=8,lk=4 and jm=6
jl=8+4----> 12

jn=jl*jk/jm-----> jn=12*8/6----> jn=16

the answer is
jn=16

A number cube is tossed and a spinner is spun. What is the probability of getting a 3 or 4 on the number cube and not getting 8

Rufina [12.5K]

Answer:

7/24

Step-by-step explanation:

Given in the question,

a number cube is tossed and a spinner is spun.

Cube have 6 in numbers

1 2 3 4 5 6

probability of having 3 or 4 = 2/6

= 1/3

Spinners are commonly made with 6, 8, 10 and 12 flat surfaces.

If a spinner has 8 flats then you have a 7/8 chance of not getting an 8.

Probability of getting a 3 or 4 on the number cube and not getting 8

"and" mean multiplication

7/8 x 1/3

-5(4m - 2) = -2/3 + 6m).

Anna35 [415]

Answer:

m=16/39

Step-by-step explanation:

-5(4m-2)=-2/3+6m

-20m+10=-2/3+6m

-20m-6m=-2/3-10

-26m=-2/3-30/3

-26m=-32/3

26m=32/3

m=(32/3)/26

m=(32/3)(1/26)

m=32/78

m=16/39
