A full-service salon charges $15.00 for a haircut and $0.45 per hair roller used in a perm. What is the minimum number of hair rollers that your
budget will allow if you must spend more than $34.00, but less than $50.00 on the haircut and perm?
Answer:
43 hair rollers.
Step-by-step explanation:
The cost of the haircut ($15.00) and the hair rollers (0.45*43) would equal $34.35, just passing the minimum amount of $34.00.
A rental car company charges $68.64 per day to rent a car and $0.12 for every mile driven. Jaxon wants to rent a car, knowing that:
•He plans to drive 500 miles
•He has at most $210 to spend
What is the maximum number of days that Jaxon can rent the car while staying within his budget?
Answer:
Step-by-step explanation:
x is the number of miles driven, and I'm assuming that's supposed to say that he plans on driving 500 miles per day and has $210 to spend. We need a cost equation for his trip. $68.64 is the flat fee the company charges regardless of how many miles, x, are driven. If they charge $.12 per mile, that's the rate per mile of the equation which is the same thing as the slope of the linear equation. The cost equation is
y = .12x + 68.64
If he has $210 to spend, let's see how many miles he can go on that by subbing in 210 for y:
210 = .12x + 68.64 and
141.36 = .12x so
x = 1178
He can drive a total of 1178 miles with $210. If he drives 500 miles per day, 1178/500 = 2.356 days. So depending upon when he has to return the car and assuming it's in the morning, he can keep the car for 2 full days and stay within his budget.

look at the rectangle and the square. ada says the length of diagonal SQ is two times the length of diagonal OM. is ada correct? justify your answer and show all of your work your work should state the serum you use to find the length of the diagonals.
Answer:
No Ada is not correct
Step-by-Step Explanation:
The length of diagonal SQ is not two times the length of diagonal OM. When you split the rectangle using the diagonal you can make a right triangle and use the Pythagorean Theorem to the rest of it.
This would be the Rectangle:
a^2+b^2=c^2
8^2+16^2=c^2
64+256+c^2
320=c^2
√320
17.8
This would be the Square:
a^2+b^2=c^2
8^2+8^2=c^2
64+64=c^2
128=c^2
√128
11.3
Now when I divide these answers that I came up with I get 1.7 which is not equal to 2 therefore SQ is not two times bigger than OM.

math question:
simon believes that 3^0 • 3^2 is equal to 1 because 0 • 2 = 0 and any number raised to a power of 0 is 1. Is Simon correct? Justify your response.
Answer:
Simon is incorrect
Step-by-step explanation:
3^0 is not 0, it is 1.
A way of thinking about this is if to get from 3^2 to 3^1, you need to divide by 3, then to get from 3^1 to 3^0 you need to divide by 3 again. 3 divided by 3 is 1.
This means 3^0*3^2=1*9=9

Find the Z-score for Tiffany's exam grade. Round to two decimal places.
Answer:
0.85
Step-by-step explanation:
The Z-score for Tiffany's exam grade will be 0.85. The value of Z score for the different distribution is different.
What is the z score?The z-score is a numerical assessment of a value's connection to the mean of a set of values, expressed in terms of standards from the mean, that is used in statistics.
The Z score is found as;
[tex]\rm Z= \frac{x-\mu}{\sigma} \\\\ Z=\frac{80-77}{3.5} \\\\ Z=0.85[/tex]
Hence,the Z-score for Tiffany's exam grade will be 0.85.

Sally paid $1.50 for pounds of apples at the Grocery Mart. Fred paid $1.95 for 3 pounds of apples at the Corner Fruit Stand. How much did Sally pay per pound of apples? (enter in the format of money, do not use the $ sign) Answer value'
Part A: Sally paid less money per pound than Fred did
Part B: John paid $3.58 for 5.5 pounds of apples at the Grocery Mart
Part C: y = 0.65x
Step-by-step explanation:
Part A:
Sally: 1.5/2.5 = x/1
cross multiply: 2.5x = 1.5*1
simplify: 2.5x = 1.5
divide both sides by 2.5: x = 0.6
Fred: 1.95/3 = x/1
cross multiply: 3x = 1.95*1
simplify: 3x = 1.95
divide both sides by 3: x = 0.65
Fred paid 65¢/pound while Sally paid 60¢/pound
Part B:
price/pound*amount John bought: 0.65/1 = x/5.5
cross multiply: 1x = 0.65*5.5
simplify: x = 3.575
Part C:
y = 0.65x

You've decided you want a plant for your room. At the gardening store, there are 444 different kinds of plants (tulip, fern, cactus, and ficus) and 444 different kinds of pots to hold the plants (clay pot, plastic pot, metal pot, and wood pot).
If you randomly pick the plant and the pot, what is the probability that you won't get a clay pot or a cactus?
Answer:
56.25%
Step-by-step explanation:
First, we need to find the total number of possible outcomes. We do this by multiplying the total number of plants by the total number of pots like so...
4 * 4 = 16 outcomes
Now we need to do the same but removing the cactus and clay pot from the list...
3 * 3 = 9 outcomes.
Now, to find the probability we need to divide the number of outcomes that do not include cactus and clay pot by the total original number of outcomes.
9 / 16 = 0.5625 or 56.25%
Finally, we can see that the probability of not getting a clay pot or cactus is 56.25%

Janelle has a babysitting job for the sunumer. She works from 7 AM to 2 P.M. with a 30-minute, unpaid break in the middle of the day. She is paid $4.50 per hour. How much money does Janelle make in 5 days?
Answer: $146.25
Step-by-step explanation:
To solve the question, we need to first calculate the number of hours between 7 AM to 2 P.M which is 7 hours but we are told that there is a 30 minutes break. Therefore, he works for 6 hours 30 minutes which is 6 1/2 hours.
She's paid $4.50 pee hour, therefore the amount paid per day will be:
= 6 1/2 × $4.50
= 6.50 × $4.50
= $29.25
The amount that she'll make in 5 days will be:
= $29.25 × 5
= $146.25
