For a Saturday matinee, adult tickets cost $7.50 and kids under 12 pay only $6.00. If 80 tickets are sold for a total of $525, how many of the tickets were adult tickets and how many were sold to kids under 12?
They sold ___ adult tickets and _____ kids tickets.
Answer:
They sold 30 adult tickets and 50 kids tickets.
Step-by-step explanation:
This question is solved by a system of equations.
I am going to say that:
x is the number of adult tickets sold
y is the number of kids tickets sold.
80 tickets are sold
This means that [tex]x + y = 80[/tex], or also, [tex]x = 80 - y[/tex]
For a Saturday matinee, adult tickets cost $7.50 and kids under 12 pay only $6.00. Tickets were sold for a total of $525.
This means that:
[tex]7.5x + 6y = 525[/tex]
Since [tex]x = 80 - y[/tex]
[tex]7.5(80 - y) + 6y = 525[/tex]
[tex]600 - 7.5y + 6y = 525[/tex]
[tex]1.5y = 75[/tex]
[tex]y = \frac{75}{1.5} = 50[/tex]
[tex]x = 80 - y = 80 - 50 = 30[/tex]
They sold 30 adult tickets and 50 kids tickets.

Answer:
To find the radius, just take half of the diameter. The answer is 2.
Step-by-step explanation:
Semicircle Area and Perimeter
Area (A)
6.2832in²
A = πr²/2 = 2 * π [in²] ≈ 6.2832 [in²]
Perimeter (L)
10.2832 in
L = πr + d = 2 * π + 4 [inch] ≈ 10.2832 [inch]

The radius of the semicircle is 2 kilometers.
What is a diameter?A straight line that runs through the sideways of a body or figure, particularly a circle or sphere, is called as a diameter of a circle or sphere.
Given:
The diameter of a semicircle is 4 kilometers.
Then the radius of the semicircle,
= diameter / 2
= 4/2
= 2 kilometers.

You were born, your mother deposited 2000 in an account that pays 5% simple interest. How much would the balance be in your account when you enter college 18 years after?
A. 18000
B. 1800
C. 3800
D. 20000
Answer:
C
Step-by-step explanation:
the formula for simple interest is given as A=P(1+rt), where A is the final balance, P is the initial principal balance (the amount of money that you start out with), r is the annual interest rate, and t is the time
we know that the mom deposited 2000 into an account when the person was born. This is our initial principal balance (the amount of money started out with)
substitute that value into the formula to get:
A=2000(1+rt)
we also know the rate, which is 5% and the time, which is 18
5%=0.05 (we need it as a decimal)
so substituting the values into the equation:
A=2000(1+0.05*18)
A=2000(1+0.9)
A=2000(1.9)
A=3,800
therefore the answer is C

Which of the following rational functions is graphed below?
Answer:
[tex]A = \frac{1}{(x-1)(x+1)}[/tex]
Step-by-step explanation:
Looking at the dashed lines in the graphic, these functions have two discontinuities, at x = -1 and at x = 1.
A discontinuity in a rational function is a point in which the denominator of the function is 0.
For these options, the denomiator is 0 at both x = -1 and x = 1 for only option A, so the answer is:
[tex]A = \frac{1}{(x-1)(x+1)}[/tex]

Find the surface area of a number cube if the height is 3cm.
Answer: 54 cm²
Step-by-step explanation:
To find the area we have to:
1) Multiply 3 x 3= 9 (we do this because a cube has equal sides so if the height is 3 then the base will be 3).
2) Then take 9 and multiply it by the number of sides of a cube (6 sides)
so, do 9 x 6 = 54cm²
Hope that helped! :)
Answer:
54 cm^3
Step-by-step explanation:
here's your solution
==> surface area of cube = 6a^2
==> a = 3 cm
==> surface area = 6*3^2
==> surface area = 6*9
==> surface area of cube = 54 cm^3

Hey yall!! How do I do this ???
Answer:
Step-by-step explanation:
just pick three values (numbers) into the function and calculate the other unknown
You can pick an X or you can pick a Y, then solve for Y or X respectively.
Record these x,y pairs in the table
once you have at least two points you can graph the function
y = mx + b y-intercept form of the line function
m = slope b is the value of y when x = 0
y = -5x/2 -5 let x = 0 solve for y
y = -5(0)/2 -5
y = 0 - 5
y = -5
y = -5x/2 -5 solve for x
y + 5 = -5x/2 - 5 + 5 add 5 to both sides
y + 5 = - 5x/2
(y +5 )(-2/5) = (-5x/2) (-2/5)
(y +5 )(-2/5) = x let y = 0
(0) +5)(-2/5) = x
5(-2/5) = x
-2 = x
I'll let you have the third variable to pick and solve for the dependent variable. The dependent variable is just wha it sounds like, it is dependent on which ever independent (the value you randomly pick) variable.
Pick either x or y then solve for y or x
y = -5x/2 -5 solve for y
x = (-2/5) (y +5) solve for x

Answer:
62° & 54°
Step-by-step explanation:
Answer 21 :-
We know that the measure of a straight line is 180° .
x + 118° = 180° x = 180° - 118° x = 62°Answer 22:-
2x + 1 + 71 = 180 2x = 180 - 72 2x = 108 x = 54°Answer:
62° & 54°
Step-by-step explanation:
Answer 21 :-
We know that the measure of a straight line is 180° .
x + 118° = 180°
=> x = 180° - 118°
=> x = 62°
Answer 22:-
2x + 1 + 71 = 180
=> 2x = 180 - 72
=> 2x = 108
=> x = 54°
