Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $3,142 was collected on the sale of 1,330 tickets. How many of each type of ticket were sold?
The basketball game sold
______adult tickets and
_______student tickets.
Answer:
453 adult tickets and 877 student tickets were sold.
Step-by-step explanation:
Given that adult tickets to a basketball game cost $ 5 and student tickets cost $ 1, and a total of $ 3,142 was collected on the sale of 1,330 tickets, to determine how many of each type of ticket were sold the following calculations must be performed:
5 - 1 = 4
1330 x 1 = 1330
3142 - 1330 = 1812
1812/4 = 453
1330 - 453 = 877
877 x 1 + 453 x 5 = X
877 + 2265 = X
3142 = X
Therefore, 453 adult tickets and 877 student tickets were sold.

Which are the solutions of x^2 = 19x + 1?
Answer:
x = [tex]\frac{19+\sqrt{365}}{2}, \frac{19-\sqrt{365}}{2}[/tex]
Step-by-step explanation:
1. Move everything to one side of the equation.
x^2 - 19x - 1 = 0
2. Use the quadratic formula where a = 1, b = -19, and c = -1.
x = (-b +- sqrt(b^2-4ac)) / 2a
If you plug those numbers into that formula, you will get the result listed above
Answer:
B
x₁ = [tex]\frac{19-\sqrt{365}}{2}[/tex], x₂ = [tex]\frac{19+\sqrt{365} }{2}[/tex]

In triangle FGH shown below, what is the measure of < F degrees?
Record your answer and fill in the bubbles on your answer document. Be sure to use
the correct place value.
Answer:
∠F = 19.5°
Step-by-step explanation:
The sum of all of the angles in a triangle is 180°
∠F + ∠H + ∠G = 180°
∠F + 127° + 33.5° = 180°
∠F + 160.5° = 180°
-160.5° -160.5°
∠F = 19.5°

Answer:
Step-by-step explanation:
1) Regular price = $ 20
Reduction = 18% of regular price
= 0.18 * 20
= 3.6
Discount price = 20 - 3.6 = $ 16.4
2) Regular price = $ x
Reduction = 18% of regular price
= 0.18 * x
= 0.18x
Discount price =$ (20 - 0.18x)
3) Discount price = $ 18.45
Let the regular price be x
(100 - 18)% of x = 18.45
82% of x = 18.45
[tex]\frac{82}{100}*x=18.45\\\\ x = 18.45* \frac{100}{82}\\\\ x = 22.50[/tex]
Regular price = $22.50

Answer:
7×10⁻¹ +6×10⁻² +5×10⁻³
Step-by-step explanation:
Place value in any place-value number system increases by a factor of the base for each place to the left of the "decimal" point. It is reduced by a factor of the base for each place to the right of the "decimal" point.
For base-10 numbers, the powers of 10 are -1, -2, -3, ... as you go to the right of the decimal point. Hence the number 0.765 decomposes as ...
7×10⁻¹ +6×10⁻² +5×10⁻³

Answer:
68 in^2
Step-by-step explanation:
the shape is a trapezoid
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs
Characteristics of a trapezoid
It has 4 vertices and edges
If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram
Area of a trapezoid = x (sum of the lengths of the parallel sides) x height
the dimension of the height is not given. We have to determine the value of the height using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
10² = 6² + height²
100 = 36 + height²
height = 64
the square root of 64 is 8
the height is 8
1/2 x (8 + 9) x 8 = 68in^2

Step-by-step explanation:
The correct answer is ''B. 5(2x + 5)''
Justin is marking a border for a garden. He walks 200 feet to the east, then turns and
walks 120 feet due south, before finally walking in a straight line back to his original
starting point. To the nearest foot, how far does Justin walk in all?
Answer
feet
Answer:
d = 233.23 feet
Step-by-step explanation:
Given that,
Justin walks 200 feet to the east, then turns and walks 120 feet due south.
We need to find the total distance walked by Justin. Let the distance be d.
We can use the Pythagoras theorem to find it such that,
[tex]d=\sqrt{d_1^2+d_2^2} \\\\d=\sqrt{200^2+120^2} \\\\d=233.24\ feet[/tex]
So, he walk 233.23 feet in all.
Krysta knit a total of 16 centimeters of scarf over 8 nights. How many nights will Krysta have
to spend knitting in order to knit a total of 46 centimeters of scarf? Assume the relationship is
directly proportional.
nights
Answer:
23 nights
Step-by-step explanation:
What does "Proportional" Mean? Proportional means that the ratio is the same throughout.
Step One: First, to set this up, we will put the 16 centimeters for the numerator and then the 8 nights on the bottom. The bottom is the independent variable because we can't physically change the number of nights. 16/8.
Step Two: Now, we have to scale this up to 46. Because the 46 is the centimeters, we have to do 46/16 to see how much we need to scale it by: 46/16= 2.875.
Step Three: Lastly, we can multiply 8 by 2.875 to see how many nights it took: 8 times 2.875 is 23 nights.

ZABC and ZQRS are supplementary angles.
If the measure of ZABC = 140°, what is the
measure of ZQRS?
MZQRS = [?]
Answer:
m<QRS = 40
Step-by-step explanation:
180 - 140 = 40
The measure of angle m∠QRS which is supplementary to m∠ABC is determined as 40⁰.
What is a supplementary angle?A supplementary angle is a pair of angles that add up to 180 degrees.
That is to say, if we have two angles and their measures sum up to 180 degrees, then they are supplementary angles. Each angle in a supplementary pair is called the "supplement" of the other angle.
The measure of angle QRS is calculated by applying the following formula as follows;
m∠QRS + m∠ABC = 180 (supplementary angles add up to 180)
m∠QRS + 140 = 180
m∠QRS = 180 - 140
m∠QRS = 40⁰
Thus, the measure of angle m∠QRS which is supplementary to m∠ABC is determined as 40⁰.

Mike, a local auto mechanic, charges a certain amount to diagnose and repair a car. He bases his price on the amount of time that it takes for the repair. Use the graph shown below to fill out the missing representations. Then, answer the questions that follow.
Can you also answer questions and 2 at the bottom.
Answer:
Okay ill do it from the ones given
Verbal Description:
Well it seems like Mike is charging a one time fee of 50 dollars each no matter what and after that its 30 dollars per hour.
Equation:
Assuming X is hours and C is total cost
50+30x= C
Table: (this will be in the order of hours, process and total)
0- (50+30*0) -0
1- (50+30*1) -80
2- (50+30*2) -110
3- (50+30*3) -140
4- (50+30*4) -170
5- (50+30*5) -200
6- (50+30*6) -230
Graph:
There are no instructions or questions for graph but if there is let me know in the comments
Questions:
#1) The rate of change for the graph is 30 dollars per hour or 30/1. Since for every hour its +30 plus the one time fee.
#2) The y-intercept here is 50 or in this case the one time payment fee.

Answer:
Yes, Chris will score.
Step-by-step explanation:
To get the ball in the goal, the ball must be below 8ft (the height of the goal) when the ball passes the 25ft mark; ie, Chris will score if f(x)<8 when x=25:
f(x)=-0.05(x-16)²+11
f(25)=-0.05(25-16)²+11
=-0.05(9²)+11
=-0.05(81)+11
=11-4.05
=6.95
Since 6.95<8, we can see that Chris will score if Deshawn doesn't block the ball.
