Answer:
The difference in the unit rates of the jars of peanut butter is 0.4.
Step-by-step explanation:
In order to find the unit rates, you have to divide each price for the amount of units purchased with that price, which is:
27.12/8=3.39
26.53/7=3.79
Now, that you have the unit rate for each case, you have to subtract 3.39 from 3.79 to find the difference in the unit rates:
3.79-3.39=0.4
According to this, the answer is that the difference in the unit rates of the jars of peanut butter is 0.4.

the domain of y=x^2 is
The range of y=x^2 is
Answer:
Domain is all real Numbers
Range is all numbers over 0 - (0,
∞
)
Explanation:
One thing that you have to remember is that when you are finding the domain of a polynomial, it is all real number. it runs from
(
−
∞
,
∞
)
For finding the range, in a quadratic formula, you have to find when the finction has it's vertex. That is the place that the max or min happens and then you can find the range from there.
in this situaltion we found that the vertex is at the the origin at (0,0)
therefore the range is (0,
∞
)
Answer:
the domain of y=x^2 is: all real numbers
the range of y=x^2 is: y >= 0

Answer:
86%
Step-by-step explanation:
28 were placed on suspension
200 are total (including that 28)
not placed on suspension are the rest, so 200-28=172
172 out of 200 = 86% not placed on suspension
Answer:
86% Pls consider marking brainliest if correct.
Step-by-step explanation:
Okie lets see
In all : 200
Removed : 28
To find percentage : 200-28/200
200 - 28 = 172
172/200 = (172/2)/(200/2)
I did this because 200 is 100x2, and because percentage is over 100
172/2 = 86
200/2 = 100
86/100 = 0.86 = 86%
Hermes earns $6 an hour for babysitting. He wants to earn at least $168 for a new video game system. Determine the number of hours he must babysit to earn enough money for the video game system. Then interpret the solution.
Answer:
28 hours
Step-by-step explanation:
6x28=168
To earn atleast $168, Hermes should do babysit for atleast 28 hours.
What is inequality?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.
How to form inequality?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.

I have no idea what set builder is, so I'll just solve it if that's okay.

First, to cancel out -3, you need to add it to both sides.

Joseph took a taxi from his house to the airport. The taxi company charged a pick-up
fee of $3.10 plus $2 per mile. The total fare was $21.10, not including the tip. Write
and solve an equation which can be used to determine m, the number of miles in the
taxi ride.
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.
