Answer:
27
Step-by-step explanation:
if the theater sold 36 adult tickets and the ratio of adult to children was 4:3, we already know that they sold more adult tickets than children tickets. to turn 36 into 4, we divide 36/4 to get 9, 4*9=36 so we have to do this to the 3, 3*9=27. 36:27 is equal to 4:3.

Use the function f(x) to answer the questions. f(x) = −16x2 + 60x + 16 Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)
Step-by-step explanation:
x intercept y=0
0 = 16x^2 - 60x -16
0 = 16x^2 + 4x - 64x - 16
0 = 4x (4x + 1) - 16 (4x + 1)
0 = (4x - 16) (4x + 1)
4x - 16 = 0 or 4x +1 = 0
4x = 16 or 4x = -1
x = 4 or x = -1/4
(4,0) and ( -1/4,0)
Answer:
x intercept y=0
0
= 16x^2 - 60x -16
0 = 16x^2 + 4x - 64x - 16
0 = 4x (4x + 1) - 16 (4x + 1)
0 = (4x - 16) (4x + 1)
4x - 16 = 0 or 4x +1 = 0
4x = 16 or 4x = -1
x = 4 or x = -1/4
(4,0) and ( -1/4,0)
Step-by-step explanation:
0 = 16x^2 - 60x -16
0 = 16x^2 + 4x - 64x - 16
0 = 4x (4x + 1) - 16 (4x + 1)
0 = (4x - 16) (4x + 1)
4x - 16 = 0 or 4x +1 = 0
4x = 16 or 4x = -1
x = 4 or x = -1/4
(4,0) and ( -1/4,0)
Lauren has a points card for a movie theater.
She receives 60 rewards points just for signing up.
She earns 5.5 points for each visit to the movie theater.
She needs 104 points for a free movie ticket.
Write and solve an equation which can be used to determine xx, the number of visits Lauren must make to earn a free movie ticket.
Multiply points per visit x number of visits, using x for the number of visits:
5.5x
Add that to the points she already has:
5.5x + 60
This needs to equal a total of 104 points:
5.5x + 60 = 104
Now solve for x
5.5x + 60 = 104
Subtract 60 from both sides
5.5x = 44
Divide both sides by 5.5
X = 8
She needs 8 more visits

Royce is folding a piece of paper to make an origami figure. Each time he folds the paper, the thickness of the paper is doubled. The paper starts out flat, with a thickness of 2 millimeters.
A. Write a list of six ordered pairs showing the output as the thickness of the paper when the input is the number of times it is folded. Explain how you came up with your ordered pairs.
B. Is this relation a function? Explain why or why not using the ordered pairs you came up with in Part A.
(Answer to get 50 pts and brainly)
Answer:
A.
(0, 2) (1,4) (2,8) (3,16) (4,32) (5,64)We start with (0,2) because before it's folded it has a thickness of 2mm. each consecutive fold doubles the y value.
B.
Yes it is a function because no x value is repeated
The list of six ordered pairs are {(0, 2), (1,4), (2,8), (3,16), (4,32), (5,64)}, and it is a function.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
Royce is folding a piece of paper to make an origami figure. Each time he folds the paper, the thickness of the paper is doubled.
Let y be the total thickness and x be the number of folds:
[tex]\rm y = 2^{x+1}[/tex]
Plug x = 0, 1, 2, 3, 4, 5,
Wea get list of six ordered pairs:
= {(0, 2), (1,4), (2,8), (3,16), (4,32), (5,64)}
This is an exponential function that passed the vertical test, it is a function.
Thus, the list of six ordered pairs are {(0, 2), (1,4), (2,8), (3,16), (4,32), (5,64)}, and it is a function.

The quadratic function h(t) = −4.9t^2 + 50t + 2 represents the height, in meters, of a toy rocket t seconds after launch. How many seconds will it take the toy to reach the ground? State your answer to the nearest whole second.
Answer:
The toy reaches the ground in 10 sec
Step-by-step explanation:
When the rocket hits the ground, h becomes zero (0). Thus, our problem here is to solve the equation h(t) = −4.9t^2 + 50t + 2 = 0,
Because of the fractional coefficient -4.9, it's best to use the quadratic equation here. The coefficients of the t terms are {-4.9, 50, 2}. Thus,
the discriminant is b^2 - 4ac = 50² - 4(-4.9)(2) = 2539.2, and the square root of this is 50.39.
The quadratic formula is as follows:
-b ± √discriminant
t = -------------------------------
2a
which here is:
-50 ± 50.39
t = ------------------------ Since t represents time, only the positive result
-9.8 is relevant here; it is 10.24 sec,
which rounds off to 10 sec
The toy reaches the ground in 10 sec

The volume would be...
The surface area would be....
Hi, sorry for a late response, but here are the answers if they are still helpful?
The volume would be about 4,188.79
(if rounded and if not the answer is below and so is the work.)
Volume = 4
—— πr3
3
= 4
—— ✖️ π ✖️ 103
3
= 4188.7902047864 centimeters^3
The surface area would be about 1,256.64
(if rounded and if not the answer is below and so is the work.)
Surface Area = 4πr2
= 4 × π × 102
= 400π
= 1256.6370614359 centimeters^2
Kirin is designing a doghouse. The base of the doghouse will be made of wood and shaped like a rectangle with a half-circle on each side as shown below. How much wood will Kirin need to build the base of the doghouse? Use 3.14 for π and round your answer to the nearest foot. Show all work.
Answer:
EASY WAY
Step-by-step explanation:
Length of rectangle= 13 feet
base of semi circle/ rectangle breadth = 1.6 feet
area =
13 into 1.6
=20.8f
semi circle= 1/2 pie r 2
1/2 x 3.14 x 0.8 x square

The theoretical probability of selecting a consonant at random from a list of letters in the alphabet is 21/26. Wayne opens a book, randomly selects a letter on the page and records the letter. He repeats the experiment 200 times. He finds p(consonant) = 60%. How does the theoretical probability differ from the experimental probability? What are some possible sources for this discrepancy. I will mark brainlest
Answer:
The theoretical probability in this case is calculated by taking the number of consonants in the alphabet and dividing it by total number of letters in the alphabet and the distribution of letters in the written language is different than the distribution of letters in the alphabet.

Answer:
C
Step-by-step explanation:
First find the area of the entire figure.
L= 36
W = 20
Area = 36 * 20 = 720
Find the area of the left right triangle.
Height = 20
Base = 1/2 * 36 = 18
Just as an aside, let me be a little grumpy for a moment. You should never have to guess what a dimension is on a diagram. It's sloppy. However for this problem you have no choice. But you could think to complain to your teacher.
Area = 1/2 * base * height
Area = 1/2 * 18 * 20 = 180
Find the area of the bottom right triangle.
The height is 1/2 20 = 10
The base is 36
Area of the lower triangle = 1/2 * 36 * 10 = 180
Area of the shaded figure = 720 - 180 - 180 = 360
Use 4's and any of the operations: +, -, × and ÷ to write number sentences.
Example: (4+4)÷(4+4)= 1
What equals 2?
What equals 3?
What equals 4?
What equals 5?
Answer:
Step-by-step explanation:
(4x4)÷(4+4) = 2
(4x4)÷ (4 +4) - 4= 4
(4+4)+(4÷ 4)- 4= 5
(4+4)- (4÷4) - 4= 3

When a spaceship full of scientists landed on Planet Q, they found that 3/8 of the 160 aliens had 3 eyes. The rest of the aliens had 5 eyes. How many eyes total do the 160 aliens have?
Answer:
680 eyes.
Step-by-step explanation:
160 · 3/8 = 60
60 aliens have 3 eyes. That means the other 100 aliens have 5 eyes.
60 · 3 = 180
100 · 5 = 500
500 + 180 = 680
Therefore, the 160 aliens have a total of 680 eyes.
