Answer:

28 hours

Step-by-step explanation:

6x28=168

To earn atleast $168, Hermes should do babysit for atleast 28 hours.

Inequality is just like an equation showing relationship between two or more variables but this is expressed in greater than ,less than form.

It defines a range of value of the relationship.

We have been given that Hermes earns $6 per hour for babysitting and he wants to earn atleast $168 for a new video game. We have to calculate the minimum number of hours that he should do babysit in order to earn $168.

We know that total revenue will be number of hours* payment of 1 hour.

let the number of hours that he does babysit is x.

The inequality will be :

6x>168

x>168/6

x>28

Hence to earn atleast $168 he should work for atleast 28 hours.

Answer:

you can decide if you want this answer or not  :D

Step-by-step explanation:

1st  , notice that our problem is about an eight part whole.  I mean,  the questions are around an object of 8 parts.  so start thinking 1/8 ths

A) asks about P(7)  ... they want to know.. how often the spinner will land on 7. so if it's totally random, 7 will happen just as likely as any of the other numbers so 7 will happen  1/8 th of the time

as a fraction  it's  1/8  as a decimal it's 0.125 and as a percent it's 12.5 %

B) asks about  P(2 or 6 )   [ btw, p here stands for probability ]  

so it's  1/8 + 1/8 =  1/4  or one quarter of the time we would get a 2 or a 6

as a fraction it's  1/4  , as a decimal it's 0.25  and as a percent it's 25%

C)   asks  about P( greater than 4)  or  P( >4)   so that's the whole left side of the circle :0  

as a fraction it's 1/2  as a decimal it's 0.5  and as a percent   it's 50%

D) P( not a 5) or P( ~=5)  so every thing but a 5

as a fraction that's 7/8  as a decimal it's 0.875 and as a percent that 87.5 %

I'll take the odds on that last one to win the lottery plz  :)

Answer:

2m + 3.10 = 21.10

m = 9

Step-by-step explanation:

First Step

2m + 3.10 =21.10

Subtract 3.10 from both sides

Second Step

2m = 18

Divide 2 from both sides

m = 9

The equation is 2m + 3.10 = 21.10

And, the number of miles in the taxi ride is m = 9.

Here,

Joseph took a taxi from his house to the airport. The taxi company charged a pick-up fee $3.10 plus $2 per mile. The total fare was $21.10.

Now,

The equation is written as,

2m + 3.10 = 21.10

Subtract 3.10 from both sides

2m = 18

Divide 2 from both sides

m = 9

Hence, The equation is 2m + 3.10 = 21.10

And, the number of miles in the taxi ride is m = 9.
