The theater group sold adult and student tickets for the play. They sold a total of 560 tickets. Each adult ticket was $8 and each student ticket was $3.50. The group took in a total of $3166. How many of each type of ticket was sold for the play?
Answer:
268 adult and 292 student tickets sold
Step-by-step explanation:
a = number adult tickets sold
s = number student tickets sold
a + s = 560
8a + 3.50s = 3166
a = 268 adult tickets
s = 292 student tickets
And so another math question appears, wooooo,,

Answer:
LV = OE =34
Step-by-step explanation:
Due to the rectangle theory,
LV = OE
3x + 10 = 5x-6
-2x = - 16
x = 8
LV = 3(8) +10 = 34
OE= 5(8)-6 = 34

Steve manages a skate park and he has been analyzing the attendance data. Steve finds that the number of visitors increases exponentially as the temperature increases, and this situation is represented by the function f(x) = 5x. Steve also finds a linear equation that models the number of people who leave the park early depending on the change in temperature, and it is represented by g(x) = −x 6. The graph of the two functions is below. Find the solution to the two functions and explain what the solution represents.
Answer:
See the Analysis
Step-by-step explanation:
Solution: From the problem
[tex]\left \{ {{f(x)=5^{x} } \atop {g(x)=-x+6}} \right.[/tex]
From 1 and 2
[tex]5^{x}=-x+6\\ x=1, y=5[/tex]
It means that the temperature is leaving as many people as it is increasing.

Answer:
The length of the missing leg is six
Step-by-step explanation:
Assuming that this is a right triangle, you can use the Pythagoras theorem
12^2+x^2=sqrt180^2
144+x^2=180
x^2=36
x=6
Therefore, the length of the missing leg is six.
Answer:
Taking the above as a right angled triangle...
Pythagoras' rule can be applied to get the Missing side.
It goes...
Hyp² = Opp² + Adj²
Which translates to Hypotenuse, Opposite and Adjacent respectively.
Hyp = √180
Opp= 12
So we're missing Adj
Making adj the subject.
Adj = √ Hyp² – Opp²
= √[(√180)² – (12)²
= √ [ 180 – 144]
= √36
Adj = 6ft.
The area of a rectangle is (x4 4x3 3x2 – 4x – 4), and the length of the rectangle is (x3 5x2 8x 4). If area = length × width, what is the width of the rectangle?.
The width of the rectangle, for which area and length provided in polynomial equation form is,

What is the area of a rectangle?Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,
[tex]A=a\times b[/tex]
Here, (a)is the length of rectangle and (b) is the width of the rectangle
The area of the given rectangle is,
[tex]A=(x^4 +4x^3 +3x^2 - 4x - 4),[/tex]
The length of the given rectangle is,
[tex]L=x^3+ 5x^2 +8x+ 4).[/tex]
As, the area of a rectangle is the product of the length and the width of the rectangle. Let suppose the width of the rectangle is f(x). Therefore,
[tex](x^4 +4x^3 +3x^2 - 4x - 4)=(x^3+ 5x^2 +8x+ 4)\times f(x)[/tex]
Solve it further as,
[tex]f(x)=(x^4 +4x^3 +3x^2 - 4x - 4)-(x^3+ 5x^2 +8x+ 4) \\f(x)=(x^4 +4x^3 +3x^2 - 4x - 4-x^3+ 5x^2 +8x+ 4[/tex]
Separate the like terms with same power of variable as,
[tex]f(x)=x^4 +4x^3-x^3 +3x^2 + 5x^2- 4x +8x- 4 + 4\\f(x)=x^43x^3+8x^2+4x[/tex]
Hence, the width of the rectangle, for which area and length provided in polynomial equation form is,
[tex](x^43x^3+8x^2+4x)[/tex]

help me with angle sum theorem please what is y
Answer:
y = 140
Step-by-step explanation:
All angles inside the triangle will equal 180
Set your formula up as
180 = x + 120 + 20
180 - 120 - 20 = x
40 = x
y+x will also equal 180, therefore
180 = y + x
180 = y + 40
180 - 40 = y
140 = y

Use the function: g(x) = (x + 2)(x - 1)(x - 2) a) Find the zeros of the function. b) Find the y-intercept of the function.
Answer:
The zeros are -2, 1, and 2
Step-by-step explanation:
You have to set each individual equation equal to zero.
ex: (x+2) x+2=0 move the number to the right hand side to get x alone x=-2
as for the y intercept I don't know
Answer:
see explanation
Step-by-step explanation:
g(x) = (x + 2)(x - 1)(x - 2)
To find the zeros let g(x) = 0 , then
(x + 2)(x - 1)(x - 2) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 1 = 0 ⇒ x = 1
x - 2 = 0 ⇒ x = 2
The zeros are x = - 2, x = 1, x = 2
To find the y- intercept substitute x = 0 into g(x)
g(0) = (0 + 2)(0 - 1)(0 - 2) = 2(- 1)(- 2) = 2 × 2 = 4
The y- intercept is 4 or (0, 4 )

i need help really bad im slow
Answer:
Always try to isolate the variable by doing the INVERSE operation of the given.
so x-5=6
So its -5
You add 5 since its the inverse of it.
So add 5 to both sides or (c)
Answer:
C.) Add 5 to both sides.
Step-by-step explanation:
x - 5 = 6
Add five to both sides.
x - 5 = 6
+ 5 + 5
-5 and +5 cancel out. 6 + 5 is 11.
x = 11

the area of the rectangle shown is 66m^2
width = 4 2/5
length = x
work out the missing length x
Answer:
143cm
Step-by-step explanation:
Area=2(l+b)
Substitute the values for the variables.
66=2(l+22/5)
66=2xl+2x22
5
66=2l+44
5
Cross multiply
66x5=2l+44
330=2l+44
Collect like terms
-2l = 44-330
-2l = -286
-2l = -286
-2 -2
l=143
The missing length is 143m.
Jake has 3 more than twice the number of marbles that Kylie has. Let m represent the number of marbles Kylie has.
The expression ____represents the number of marbles Jake has.
Answer:
2m + 3
Step-by-step explanation:
Jake has 3 more than twice the number of marbles that Kylie has. Let m represent the number of marbles Kylie has.
3 + twice of Kylie's marbles = twice of Kylie's marbles + 3
The amount of marbles kylie has is represented with m, making it (2 x m) + 3 = 2m + 3.
A cell phone company conducted a survey to determine if customers were satisfied with their cell phone service. The survey sample consisted of all customers who had contacted the company within the past year and who agreed to participate. Of the 420 customers surveyed, 65% reported that they were not satisfied with their service.
Which statement about this sample is true?
A Exactly 65% of all customers are not satisfied with the cell phone service.
B The sample includes all customers who made complaints to the company within the last year, and therefore is representative of the population. ,
C The sample might not be representative of the population because, in general, satisfied customers have no reason to contact the company.
D No generalizations can be made from this sample because the sample size is too small.
The statement that is true about the given sample is that;
B. The sample includes all customers who made complaints to the company within the last year, and therefore is representative of the population. ,
Sample Statistics Interpretation
We are given;
Sample size; n = 420
Sample proportion; p^ = 65%
Now, from the sample size and proportion, we can say that;
Exactly 65% of the surveyed customers were not satisfied with the cell phone service. Now, this only represents those surveyed and not the entire population. Thus it is not exactly 65% of all customers that are not satisfied with the cell phone service.
Option B is correct because the 420 customers surveyed is a sample from the population of all their customers within the last year.
