Every year, Kate and her sister attend 'The Nutcracker' at the Bloomington Ballet. Last year, orchestra seating cost $50 per ticket. This year, each ticket was 8% cheaper. What was the cost of each ticket this year?
Answer: 6.25
Step-by-step explanation:
Answer:
$46
Step-by-step explanation:
8% of 50 = 4
50 - 4 = 46
Therefore, 50 - 8% is $46.
Please Help, i need to get this done right now
Answer:
16 minutes
Step-by-step explanation:
80% of 20 is 16, so thats your answer.
Answer:
25 Minutes.
Step-by-step explanation:
This can be solved simply by long division. First, change 80% into its decimal form, which is 0.80, and is simplified to 0.8. Then, divide 20 by 0.8.

An amusement park charges $8 for parking in addition to $1.25 per ride ticket. Write an equation to represent the total cost to visit the amusement park, then find the number of rides a person can go on, if they have $30. Identify your variables.
Answer:
Amount of rides = (30 - 8)/1.25
Answer:
c = 8 + 1.25r
the unit used is dollars
r = the amount of ride tickets purchased
c = total cost
a person could could go on 17 rides with 30$
Step-by-step explanation:
To develop the equation:
1. first, you want your total cost on one side. That is c (c =)
2. second, you need to identify the variable that changes the cost in the equation. That would be the amount of ride tickets because it changes the total cost based on how many a person buys. (c = 1.25r)
3. third, you add the variable that never changes, which is the eight dollars for parking (c = 1.25r +8)
In order to solve for a specific amount of money, you plug in the amount in place of your total cost (c) variable. In this case, you would solve 30 = 8 + 1.25r
It would look something like this:
30 = 8 +1.25r
(subtract 8 from both sides)
22 = 1.25r
(divide each side by 1.25)
r = 17.6
(round down because you can't buy a ride ticket with only 60 cents)
and you're done!
hope that helps!

Given the lines shown here, what are two possible equations for this system of equations?
Answer:
Blue line: either y=1/4x+1, y=1/5x+1, or y=1/6x+1 (depending on how u see where it intercepts in the x-axis.
Black line: either y=1/4x-10, y=1/5x-10, or y=1/6x-10 (depending on how u see where it intercepts in the x-axis.
Step-by-step explanation:
Well because they don't have the numbers it's hard to tell. But they will have the same slope which makes them parallel. So the Y intecept for the blue line would be 1 if it's how it's shown. Then the slope would be one over 4,5 or 6. Then again I cannot see numbers there so... anyways, the equation for the blue line would be about y=1/5x+1. For the black line, I think it intercepts on the -10 for the Y. So if the slope is the same so that they can be parallel then it would be y=1/5x-10. (WARNING: This answer might change if they give you the numbers of the actual line. THIS IS JUST AN ESTIMATE!! THEY ARE POSSIBLE ONES!!!!!) But remember when lines are parallel they have the same slope but different Y-intercept! Hope this helped a bit... ask me if u have any questions.
cause y=mx+b (m is the slope which is rise over run) (b is the y-intercept)

Which of the following could be the side measures of a right triangle?
A. 6 ft, 5 ft, 4 ft
B. 8 ft, 7 ft, 6 ft
C. 10 ft, 8 ft, 6 ft
D. 12 ft, 10 ft, 8 ft
Answer:
C
Step-by-step explanation:
First, let us try the first on:
sqrt (5^2+4^2)=sqrt 41 so it can't be A
Second one:
sqrt (6^2+7^2)=sqrt 85, no
Third one:
sqrt (8^2+6^2)=sqrt 100 = 10, so it is C
Answer:
C
Step-by-step explanation:
I will just say how to do C but it is the same for all of the other ones.
First I write a²+b²=c²
Then I put in the numbers and get 6²+8²=10²
After that I do the ² to all of them to get 36+64=100
Next I add 64 and 36, which equals 100
100=100

Answer: f(3) = g(3)
Step-by-step explanation:
ok so f and g are unknown numbers and 3 is equal to 3, since f and g are unknown they could be any number so that's why there the same.
Answer:
f(3) > g(3)
Step-by-step explanation:
add 3 into each equation.
f(x) = 4x^4 g(x) = 10 * 2^x
= =
f(3) = 4(3)^4 g(3) = 10 * 2³
Solve each equation.
f(3) = 4(3)^4 g(3) = 10 * 2^3
= =
f(3) = 12^4 g(3) = 20^3
= =
f(3) = 20,736 g(3) = 8,000
f(3) is greater than g(3)
f(3) > g(3)
Hope I helped.

!!Giving 15 points and will give brainliest!!Use the second list of random numbers to again calculate the experimental probability of a group having at least three girls. The results using the second list are
10%
the results using the first list.
Answer:
39% chance for only boys, 61% chance for only girls for the first two questions
the second is a bit trickier,you need a ratio for finding how many would be in 224 groups.
100:224 = 61:x, or 61/100 = x/224
Cross multiply; 100x=13664
Then, divide by 100; x=136.64, or about 137 groups would contain all girls

because 3/4 is 45 minutes.'
and 3/8 is 22.5 minutes.
45-22.5=22.5 minutes different.
is -5.1 greater than -4?
Answer:
-4 is greater than -5.1.
Answer:
No
Step-by-step explanation:
In integers, it's almost backwards. If you are looking at a scale, -4 would be further up, or closer to zero than -5.1.
So, if you are looking at negative numbers, basically, the closer the number is to zero, the greater it is.
