A box office sells balcony seats, ground-level seats, and VIP passes for shows on tour. The table shows the numbers of each type of ticket sold and the revenues for the first three shows of a tour. What is the price of each type of ticket?
Answer:
The price of one Balcony seat = $50
The price of one Ground level seat = $90
The price of one VIP seat = $180
Step-by-step explanation:
Let the price of one Balcony seat = $[tex]x[/tex]
Let the price of one Ground level seat = $[tex]y[/tex]
Let the price of one VIP seat = $[tex]z[/tex]
As per the given table:
[tex]135x+280y+29z=37170 ....... (1)\\150x+270y+58z=42240 ....... (2)\\130x+265y+29z=35570 ....... (3)[/tex]
Multiplying (1) with 2 and subtracting (2) from it:
[tex]120x+290y=32100 \\12x+29y=3210..... (4)[/tex]
Subtracting (3) from (1):
[tex]5x+15y=1600\\x+3y=320 ....... (5)[/tex]
Multiply equation (5) with 12 and subtracting (4) from it:
[tex]7y=630\\\Rightarrow y =\bold{90}[/tex]
By equation (5), putting value of [tex]y[/tex]:
[tex]x=\bold{50}[/tex]
By equation (1), putting the values of [tex]x, y:[/tex]
[tex]135\times 50+280\times 90+29z=37170\\\Rightarrow 29z=37170-31950\\\Rightarrow 29z=5220\\\Rightarrow z =\bold{180}[/tex]
Therefore, the answers are:
The price of one Balcony seat = $50
The price of one Ground level seat = $90
The price of one VIP seat = $180

2(3b-2)=2(2b+12)
Answer:
14
Step-by-step explanation:
Step 1:
2 ( 3b - 2 ) = 2 ( 2b + 12 ) Equation
Step 2:
6b - 4 = 4b + 24 Multiply
Step 3:
6b = 4b + 28 Add 4 on both sides
Step 4:
2b = 28 Subtract 4b on both sides
Step 5:
b = 28 ÷ 2 Divide
Answer:
b = 14

yes just multiply it once more by -1
Step-by-step explanation:
Find the error and and the correct answer
Answer:
Error: Multiplied both sides by 3/4 instead of 4/3.
Solution: x = 16
Step-by-step explanation:
The error is that you multiplied both sides by [tex]\frac{3}{4}[/tex] instead of dividing both sides by [tex]\frac{3}{4}[/tex].
This is an error because:
[tex]\frac{3}{4} *\frac{3}{4} x\neq x[/tex]
Actually:
[tex]\frac{3}{4} *\frac{3}{4} x=\frac{9}{16} x[/tex]
What you want to do instead is divide both sides by [tex]\frac{3}{4}[/tex]. Remember, dividing both sides by [tex]\frac{3}{4}[/tex] would be the same as multiplying both sides by [tex]\frac{4}{3}[/tex].
Now, lets find the correct answer:
[tex]\frac{3}{4}x=12[/tex]
Multiply both sides by 4/3.
x = 16
So the correct answer would be x = 16.
I hope this helps. Happy studying.
There are 55 black balls and 88 red balls in an urn. If 44 balls are drawn without replacement, what is the probability that no more than 11 black ball is drawn
Answer:
[tex]Probability = \frac{70}{143}[/tex]
Step-by-step explanation:
Given
[tex]Black = 5[/tex]
[tex]Red = 8[/tex]
[tex]Total = 13[/tex]
To solve the required probability, we need to determine the number of available selections:
There are two possible scenarios;
1: All 4 selections are red.
2. 1 selection is black, while 3 others are red
Scenario 1: All Red
[tex]^8C_4 = \frac{8!}{(8-4)!4!}[/tex]
[tex]^8C_4 = \frac{8!}{4!4!}[/tex]
[tex]^8C_4 = \frac{8*7*6*5*4!}{4!4!}[/tex]
[tex]^8C_4 = \frac{8*7*6*5}{4!}[/tex]
[tex]^8C_4 = \frac{8*7*6*5}{4*3*2*1}[/tex]
[tex]^8C_4 = \frac{1680}{24}[/tex]
[tex]^8C_4 = 70[/tex]
Scenario 2: 1 Black, 3 Red
Selecting Black:
[tex]^5C_1 = \frac{5!}{(5-1)!1!}[/tex]
[tex]^5C_1 = \frac{5!}{4!1!}[/tex]
[tex]^5C_1 = \frac{5*4!}{4!*1}[/tex]
[tex]^5C_1 = 5[/tex]
Selecting Red:
[tex]^8C_3 = \frac{8!}{(8-3)!3!}[/tex]
[tex]^8C_3 = \frac{8!}{5!3!}[/tex]
[tex]^8C_3 = \frac{8*7*6*5!}{5!3*2*1}[/tex]
[tex]^8C_3 = \frac{8*7*6}{6}[/tex]
[tex]^8C_3 = 8*7[/tex]
[tex]^8C_3 = 56[/tex]
Number of Selection = 5 * 56
[tex]Selection = 280[/tex]
Total Available Selection is calculated as thus:
[tex]Available\ Selection = 70 + 280[/tex]
[tex]Available\ Selection= 350[/tex]
Next, is to calculate the number of possible selections:
i.e 4 balls out of 13
This is calculated as:
[tex]^{13}C_4 = \frac{13!}{(13-4)!4!}[/tex]
[tex]^{13}C_4 = \frac{13!}{9!4!}[/tex]
[tex]^{13}C_4 = \frac{13 * 12 * 11 * 10 * 9!}{9!4*3*2*1}[/tex]
[tex]^{13}C_4 = \frac{13 * 12 * 11 * 10}{4*3*2*1}[/tex]
[tex]^{13}C_4 = \frac{17160}{24}[/tex]
[tex]^{13}C_4 = 715[/tex]
[tex]Probability = \frac{Available\ Selection}{Possible\ Selection}[/tex]
[tex]Probability = \frac{350}{715}[/tex]
[tex]Probability = \frac{70}{143}[/tex]

which table represents a linear function?
Answer:
the third one
Step-by-step explanation:
You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear. You can find the constant rate by finding the first difference

Describe the parametric equations which traces the unit circle starting (-1,0) in a clockwise direction.
Step-by-step explanation:
There are several ways we can do this.
x = cos t, y = sin t, t ≥ 0 traces the unit circle in a counterclockwise direction starting at (1, 0).
To change the direction, we can multiply one of these by -1. Then choose an initial value of t so that the starting point is (-1, 0).
x = -cos t, y = sin t, t ≥ 0
x = cos t, y = -sin t, t ≥ π
Or, we can change the direction by switching the equations.
x = sin t, y = cos t, t ≥ 3π/2
We can also multiply both by -1:
x = -sin t, y = -cos t, t ≥ π/2
Of these four examples, I would say the first is the simplest and most straightforward, but all of them achieve the same result.

the correct increasing order of integers of 18,-20,- 30, 70, 20 is
Answer:
-30, -20, 18, 20 and 70
Step-by-step explanation:
The given numbers:
18, -20, - 30, 70, 20
The more negative an integer is, the smaller it is. Let us rearrange the set of numbers:
-30, -20, 18, 20 and 70
Based on increasing order of integers, the numbers are:
-30, -20, 18, 20 and 70
y-3=2(x+1) please please help
Answer:
y=2x+5
Step-by-step explanation:
distribute 2 to x and 1, do this by multiplying each.
you should get y-3=2x+2.
then you have to move the -3 from the left to the right. but when you do this you have to change the -3 to a positive 3. then combine 3 and 2.
you then get the answer, y=2x+5.
