Evan worked 9 hours and
made $85.50. Henry worked 6 hours and made $57.00. Are
these two rates proportional?
Answer:
yes both of them make 9.5 the hour I know this because 85.50 divided by 9 is 9.5 9 times 9 is 81 and .5 times 9 is 4.5 so 81+4.5=85.5 and then 57 divided by 6 is 9.5 as well you can do 6 times 9 and you get 54 and then 6 times 0.5 is 3 and 54+3=57

Which of the statements is true?
A. For every value of x, the rate of change of f(x) exceeds the rate of change of g(x).
B. As x increases, the rate of change of g(x) exceeds the rate of change of f(x).
C. At approximately x = 4.74, the rate of change of g(x) is equal to the rate of change of f(x).
D. As x increases, the rate of change of f(x) exceeds the rate of change of g(x).
A statement that is true include the following: B. As x increases, the rate of change of g(x) exceeds the rate of change of f(x).
How to determine the average rate of change?In Mathematics, the average rate of change of f(x) on a closed interval [a, b] is given by this mathematical expression:
Average rate of change = [f(b) - f(a)]/(b - a)
Next, we would determine the average rate of change of the function f(x) over the interval [0, 1]:
a = 0; f(a) = 1
b = 1; f(b) = 6
By substituting the given parameters into the average rate of change formula, we have the following;
Average rate of change = (6 - 1)/(1 - 0)
Average rate of change = 5/1
Average rate of change = 5
For g(x), we have the following:
Average rate of change = (216 - 0)/(1 - 0)
Average rate of change = 216/1
Average rate of change = 216

1. A group of students went to the movie theater.
Eighteen of the students bought popcorn.
The other 60% of the students bought candy.
How many students were in the group?
2.There are 21,000 fans at a football game cheering for the home team. The other 40% of the total people in attendance are cheering for the away team. How many people are in attendance at the game?
3.Ashley sees a book bag on sale in a store for $22. This is 20% off the original price. What was the original price of the book bag?
NUMBER 1
If 18 people is 40% that means the we need to start taking 40% off of numbers
40% of 20 is 12
40% of 25 is 15
40% of 30 is 18
So the answer is 30
NUMBER 2
If 21,000 people is 60% that means 20% is 7,000 people and 7,000x5=35,000 so there is a total of 35,000 people at the game
NUMBER 3
You should start taking 20% off of numbers.
20% of 25 is 20 too low so we need to go higher
20% of 26 is 20.8 still too low so lets keep going
20% of 27 is 21.60 closer but too low
20% of 28 is 22.40 which is too high lets go back since 27 is too low and 28 is too high lets start in between
20% of 27.5 is 22.00
So the answer is $27.5.
Simplify the expression by arranging the steps in sequence, based on the order of operations. 1/6(30x+24)-1/7(63-7x)
Answer:
[tex]\frac{42}{42}[/tex] * (6x-5)
Step-by-step explanation:
Factor out 1/42 from both fractions first:
=
1/42 * (7(30x+24) - 6(63-7x))
then distribute the multiplication and combine like terms:
= 1/42 * (210x + 168 - 378 +42x)
= 1/42 * (252x-210)
Factor:
= 1/42 * 42(6x-5)
= 42/42 * (6x-5)

Which of the following values for x is true for 4x > 10
x = 34
x = 2
x = 2.5
x = 3
help!
Answer:
2.5
Step-by-step explanation:
its just 4 x x so you just times 2.5 by 4
Answer:
you can put 34 or 3 your choice!
Step-by-step explanation:
Ok so how you would find this out is first you put 4(x)>10
and you'll swap out the x for each number choice and 2.5 is the one that fits...
4(34)>10 = 136>10 yes
4(2)>10 = 8>10 well no bc 8 is less than 10
4(2.5)>10 = 10 = 10 not 10>10 so no
4(3)>10 = 12>10 yes

Which of the following equations do not represent a proportional relationship? y = 4/3x y = 2x - 1 y = x y = 1.4x
Answer:
y = 2x - 1
Step-by-step explanation:
y = 2x - 1 wouldn't be a proportional relationship. You can tell because any equation with addition or subtraction is not going to be proportional.
Answer:
y=2x-1
Step-by-step explanation:
notice how the second option, y=2x-1 is the only option that has a constant. All other options only have a coefficient on the x term. This makes it perfectly proportional by the factor of the coefficient.
In a survey of 160 people who have reptiles as pets, 40% have a pet snake. Of those with a pet snake, 25% also have a pet lizard. Of those who do not have a pet snake, 75% have a pet lizard.
Part A
Enter the correct answers in the boxes to construct a two-way frequency table to display the data.
Part B
What percentage of those surveyed have a pet lizard?
Part C
What percentage of those surveyed have both a snake and a lizard?
Percentage of people having Lizard = 55% , Percentage of people having both Lizard & Snake = 10%
Important Information : Percentage people having pet snake = 40%
C] Percentage people having pet lizard, along with pet snake = 25% of those having pet snake = 25% of 40% = 10% {Percentage of people having both snake & lizard)
Percentage of people having pet snake only = 75% of those who don't have snake = 75% of ( total - 40%) = 75% of 60% = 45%B] Total percentage of people having pet lizard = 10% + 45% = 55%

Find the sales tax.
Please also show your work so I can understand it :)
Answer:
Sales tax: 3.5$
Total Price: 73.5$
Step-by-step explanation:
the percentage of tax is that much of the total price. if there is 50% sales tax (unrealistic) and the item costs 100 dollars without any tax, then the tax would be 50 dollars. To find this, turn the percent into a decimal (move the decimal place to the left twice) and multiply that by the price. To do this with this problem, use this strategy. 70 times .05= 3.5. Therefore the tax is 3.5$. hope this helps!!

Answer:
X = 4
Step-by-step explanation:
Which equation is NOT equivalent to 5 + n = 10. Select all that apply.
5 + n -n = 10 – n
5 + n – 5 = 10 - 10
5 + n – 5 = 10 - 5
5 + n + 3 = 10 + 3
5 + n – 10 = 10 - 5
Answer:
5 + n - 5 = 10 - 10
Step-by-step explanation:
if you do 5-5 that would equal zero, and if you do 10-10 it would equal 0 also, so all you would be left with is 0 + n= 0 and that is not equal to 5 + n = 10
Answer:
5 + n - 5 = 10 - 10
