Answer:
The answer is "$13".
Step-by-step explanation:
The entrance fee for a show is [tex]\$8[/tex] for an adult, [tex]\$5[/tex] for children under 13, and [tex]\$3[/tex] for matinees (before 6 pm).
In our event, Janelle is a child as she's underneath the age of 13 who pays [tex]\$5[/tex] while she's an older person and therefore she's going to pay [tex]\$8[/tex].
[tex]\$ 8 + \$ 5 = \$ 13[/tex], therefore the overall cost for the show is 13 dollars
Luke sold 4 times as many books as Maurice. If Maurice had sold 18 more books, he would have tied Luke for first place. How many books did Luke sell?
Answer:
24
Step-by-step explanation:
I guessed and checked but 24 -18 is 6 and 6 times 4 is 24
M + 18 = 4M
18 = 4M - M
18 = 3M
M = 18/3 = 6
4M = 4(6) = 24 sold by Luke
0.32 as a mixed number

At a certain middle school, there are 200 5th graders, 220 6th graders, 180 7th graders, and 150 8th graders. The Dean of Students chooses a scholar at random to help run Community Circle. What is the probability that a 7th grader is chosen?
Answer:
6/25
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
probability that a 7th grader is chosen = total number of 7th graders / total number of students
total number of 7th graders = 180
total number of students = 200 + 220 + 180 + 150 = 750
180 / 750
To transform to the simplest form. divide both the numerator and the denominator by 30
6 / 25

YOUR ASSIGNMENT: Desert Temperatures
In this assignment, you may work alone, with a partner, or in a small group. Discuss the results of your work and/or any lingering questions with your teacher.
Temperature in the desert can be modeled by the function C(t), where t represents hours after midnight (0 ≤ t ≤ 24), and C is the temperature measured in degrees Celsius. Examine what happens to the graph when you transform the function to degrees Fahrenheit.
Circle the desert you picked:
Sahara Desert
Patagonian Desert
Death Valley California(I choose this one)
Exploring Degrees Celsius
1. Fill out the following chart to find the temperatures for t = 12 (noon) and t = 24 (midnight). (2 points: 1 point for each row)
t
C(t) = –0.30(t – 12)2 + 40
0
12
C(t) = -0.30 (12 - 12)² + 40
C(t) = -0.30 (0)² + 40
C(t) = 40
24
C(t) = -0.30 (24 - 12)² + 40
C(t) = -0.30 (12)² + 40
C(t) = -0.30 × 144 + 40
C(t) = - 43.2 + 40
C(t) = -3.2
2. Plot the three points from the chart onto the graph below. Use the plotted points to sketch the graph of C(t) = –0.30(t – 12)2 + 40. (3 points: 2 points for correct coordinates, 1 point for correct shape)
Convert the Function to Degrees Fahrenheit:
3. Suppose you want to represent the desert temperature in degrees Fahrenheit instead. How would you transform the function C(t) to make the new function, F(t)? (2 points: 1 point for each transformation)
Note: The conversion rule for Celsius to Fahrenheit is .
F(t)=9/5{–0.30 (t – 12)² + 40}+32
F(t) = -0.54 (t – 12)² + 72 + 32
F(t) = -0.54 (t – 12)² + 104
4. Take your values from the previous chart (in question 2) and convert them from Celsius to Fahrenheit. Follow the example below, and use the conversion rule to fill out the chart for degrees Fahrenheit when t = 12 and t = 24. (2 points: 1 point for each row)
t
0
12
24
5. Use the conversion formula to write the equation for the new function, F(t).
(4 points: 2 points for setting up the equation, 2 points for the answer)
Hint: Substitute the equation for C(t) into .
6. Plot the points from the Fahrenheit chart in question 4 onto the graph below. Use the plotted points to sketch out the graph of F(t). (3 points: 2 points for correct coordinates, 1 point for correct shape)
7. Compare the graph in question 6 (F(t)) with the graph in question 2 (C(t)). What changes were made to the graph of C(t) to transform it to F(t)? (1 point)
Answer:
Part 1
Given equation:
C(t) = -0.30 (t – 12)² + 40
For t = 0
C(t) = -0.30 (0 - 12)² + 40
C(t) = -0.30 (-12)² + 40
C(t) = -3.2
For t = 12 (noon)
C(t) = -0.30 (12 - 12)² + 40
C(t) = -0.30 (0)² + 40
C(t) = 40
For t = 24 (midnight)
C(t) = -0.30 (24 - 12)² + 40
C(t) = -0.30 (12)² + 40
C(t) = -0.30 × 144 + 40
C(t) = - 43.2 + 40
C(t) = -3.2
Part 2
attached below
Part 3
C(t) = –0.30(t – 12)² + 40
F(t)=9/5C(t)+32
Substituting the values:
F(t)=9/5{–0.30 (t – 12)² + 40}+32
F(t) = -0.54 (t – 12)² + 72 + 32
F(t) = -0.54 (t – 12)² + 104
5, 6 and 7, should be simplish
good luck, i hope this helps :)

Answer:
4^11
Step-by-step explanation:
[(4^3)(4^4)]÷(4^1+4^-4)
using laws of indices
(4^3)(4^4)=4^(3+4)
=4^7
(4^1 +4^-4)=4^(1-4)
=4^-3
4^7/4^-3,recalling about laws of indices if the exponentials are dividiy ,you subtract the powers give their base is equal
4^7/4^-3=4^(7-(-3)
=4^(7+3)
=4^11

Answer:
Hello! answer: 544
Hope this helps!
The surface area of the given triangular prism is 544 units³
What is a triangular prism?A triangular prism is a polyhedron made up of two triangular bases and three rectangular sides.
Given that are the dimensions of a triangular prism, we are asked to find its surface area,
Surface area = (perimeter × length)+(base area)
Surface area = [(10+10+12)×14]+(8×12)
= 32×14+96
= 448+96
= 544
Hence, the surface area of the given triangular prism is 544 units³

What is the measure of ∠A, the exterior angle of the triangle shown below? F. M∠A = 92°, because 180 – (50 + 38) = 92. G. M∠A = 272°, because 180 – (50 + 38) = 92 and 92 + 180 = 272. H.M∠A=78°,because 50–38=12and90–12=78. J. M∠A = 88°, because 50 + 38 = 88.
Answer: A is 88
Step-by-step explanation:
Sum of all angles is 180 degree.
Let the third interior angle be x.
38+50+x=180
88+x=180
x= 92
A and X are in linear pair.
A+X=180
A+92=180
A=88

What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
Given that A water tank is filled with a hose.
The table shows the number of gallons of water in the tank compared to the number of minutes the tank was
being filled.
The line of best for this data is g = 9m - 0.17.
We need to find when it is 45 minutes.
We have to put m value as 45 to find the number of gallons
g=9(45)-0.17
g=405-0.17
g=404.83
Hence, 405 gallons of water in the tank in 45 minutes.

ABCD is a cyclic quadrilateral (inscribed quadrilateral). Find the value of x and the measures of all the angles.

Step-by-step explanation:
The "trick" to this problem is knowing that opposite sides of the box add up to 180°
Now that you know that maybe you can solve this?
180= 7x+2 + 6x-4

2. Mercury High School is requiring students to purchase parking permits this year in order to
use campus parking lots. It costs the school a one-time fee of $500 to have the logo
designed. It also costs $2 per permit to print and cut out each one. They expect the average
cost of each permit to be $6.
a. Write a rational equation that describes the situation above.
b. How many parking permits does Mercury High School need to sell in order for the
average cost of a student's parking permit to be $6? Solve your equation from part (a)
to answer the question. Justify your solution as it relates to the context.
Answer:
a. $6 = ($500 + $2q) / q
b. 125
Average cost = ($500 + $2q) / q
($500 + $2x 125) / 125 = $6
Step-by-step explanation:
Average cost = total cost / quantity produced
total cost = fixed cost + variable cost
Fixed costs are costs that do not vary with output. e.g. the cost of the logo
Variable costs are costs that vary with production e.g. cost of printing and cutting
Variable cost = $2 x quantity of parking ticket sold
let q = quantity of parking ticket sold
variable cost = 2q
$6 = ($500 + $2q) / q
to determine the number of parking ticket to be sold for average cost to be $6, take the following steps
Multiply both sides of the equation by q
6q = 500 + 2q
collect like terms
6q - 2q = 500
4q = 500
q = 125
125 tickets have to be sold for average cost to the $125
to justify the answer, replace 125 in the first equation to confirm if $6 would gotten as the average cost
($500 + $2q) / q
($500 + $2x 125) / 125 = $6
