there are 800 seats in the varsity theater. during regular preformances, all seats cost $12 each. It costs the owner $275 to pay his preformers for each show. a: write an expression that could predict the owners profit if "n" people buy tickets for a preformance b: if the profit is $1,213, how many people attend? c: If the same number of people attended but the owner's expenses changed to $375, would the profit increase or decrease and by how much?
Answer:
The correct answers are the following:
A) P=12n-275
B) 124
C) Decrease by $100
Step-by-step explanation:
A) P=12n-275 - Each person (n) pays $12, then the cost/expense ($275) is subtracted from the income to get the profit.
B) 1,213=12n-275 - Plug in the value for P ($1,213).
1,488=12n - Add $275 to both sides.
124=n - Divide both sides by $12.
n=124 - This the number (n) of people that attended.
C) P=12n-375 - Change the value for expense to $375.
P=12(124)-375 - Plug in the value for n (124).
P=1488-375 - Simplify and find the difference.
P=1,113 - This is your profit.
1,113-1,213=-100 - $100 reduction/decrease of profit (or -$100 to profit)

I need to solve 12r-6s=t for r
Answer:
Simplifying
12r + -6s = t
Solving
12r + -6s = t
Solving for variable 'r'.
Move all terms containing r to the left, all other terms to the right.
Add '6s' to each side of the equation.
12r + -6s + 6s = 6s + t
Combine like terms: -6s + 6s = 0
12r + 0 = 6s + t
12r = 6s + t
Divide each side by '12'.
r = 0.5s + 0.08333333333t
Simplifying
r = 0.5s + 0.08333333333t
Step-by-step explanation:
sorry if this doesnt help
Answer:
r=s/2+t/12

You are helping your dad build a rectangular dog park. The length of the dog park feet can be represented by
8x + 2 and the width in feet can be represented by 2x - 12. If your dad bought 160 feet of fencing
(perimeter), what is the length of the dog park?
Answer:
The length of the dog park is 74 feet.
Step-by-step explanation:
Given that,
Length of park = (8x+2)..(I)
Width of park = (2x-12)...(II)
Perimeter = 160 feet
We need to calculate the value of x
Using formula of perimeter of rectangular park
[tex]P=2(l+w)[/tex]
Where, l = length
w = width
Put the value into the formula
[tex]160=2(8x+2+2x-12)[/tex]
[tex]160=20x-20[/tex]
[tex]x=\dfrac{160+20}{20}[/tex]
[tex]x=9[/tex]
We need to calculate the length of the dog park
Using equation (I)
[tex]l=8x+2[/tex]
Put the value of x
[tex]l=8\times9+2[/tex]
[tex]l=74\ feet[/tex]
Hence, The length of the dog park is 74 feet.

6) A demand curve for a product is the number of items the consumer will buy at different prices. At a price of $2 a store can sell 2400 of a particular type of toy truck. At a price of $8 the store can sell 600 such trucks. If x represents the price of trucks and y the number of items sold, write an equation for the demand curve.
Given :
When price is $2 dollars he sells 2400 units .
When price is $8 dollars he sells 600 units .
To Find :
If x represents the price of trucks and y the number of items sold, write an equation for the demand curve.
Solution :
Two points are given :
[tex](x_1,y_1)=(2,2400)[/tex]
[tex](x_2,y_2)=(8,600)[/tex]
Now , slope is given by :
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\\\m=\dfrac{2400-600}{2-8}\\\\m=\dfrac{-1800}{6}\\\\m=-300[/tex]
Now , the equation of line containing these two points and slope -300 is :
[tex](y-y_1)=m(x-x_1)\\\\y-600=-300(x-8)\\\\y=-300x+2400+600\\\\y=-300x+3000[/tex]
Therefore , equation for the demand curve is [tex]y = -300x +3000[/tex] .
Hence , this is the required solution .

[tex]V=\dfrac{P}{I}\\\\V=\dfrac{25}{1.5}\\\\V=16.67\ V[/tex]
Voltage of the motor is 16.67 volts
Let R is the resistance of the motor. Using Ohm's law to find it as follows :
V=IR
[tex]R=\dfrac{V}{I}\\\\R=\dfrac{16.67}{1.5}\\\\R=11.113\ \Omega[/tex]
Hence, this is the required solution.

~AnonymousHelper1807Lin spent 80 minutes doing homework on Monday. Each day from Tuesday
through Friday, Lin spent half as much time doing homework as the day before.
How much total time did Lin spend doing homework, from Monday through
Friday? Explain how you know. *
Answer:
240 minutes
Step-by-step explanation:
Half of 80 is 40. So multiply 40 by 4 which is 160 minutes then add the 80 which equals 240 minutes
Overall 240 minutes Lin spend doing homework from monday to friday.
What is an expression?
Expression in mathematical is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Since Lin spent 80 minutes on monday doing homework and from tuesday to friday he is doing half the work before which means he will be doing in 40 mintues now for 4 days that is from tuesday to friday.
Now overall time in mintues he spend on homework will be sum of mintues spent on monday and mintues spent from tuesday to friday :
overall = 80 + 40x4
= 240 minutes
Therefore, overall 240 minutes Lin spend doing homework from monday to friday.

A car of m = 1200. kg collides with a tree while traveling 60.0 mph. The collision occurs over a time period of 0.0500 seconds. Determine the magnitude of the force exerted on the car as it comes to rest during the collision. (1 m/s = 2.24 mph) 1.58 × 10 3N 1.44 × 10 6N 3.60 × 10 3N 6.4331 × 10 5N
Answer:
6.4331 × 10 5N
Step-by-step explanation:
Given the following :
Mass (m) of car = 1200kg
Initial Velocity (u) of car = 60 mph
Final velocity = 0 ( comes to rest)
Velocity in m/s = 60 / 2.24 = 26.785 m/s
Time (t) = 0.0500
Using the relation :
Ft = m(v - u)
Where,
v = final velocity ; u = initial velocity ; t = time ; F = force
F*0.05 = 1200(26.785 - 0)
0.05F = 32142.86 - 0
F = 32142.86 / 0.05
F = 642857.14 N
F = 6.43 × 10^5 N

Substitute values for RS, ST and RT
[tex]13y - 1 = 6y + 2 + 5y + 9[/tex]
Collect Like Terms
[tex]13y - 6y - 5y = 1 + 2 + 9[/tex]
[tex]2y = 12[/tex]
Divide both sides by 2
[tex]y = \frac{12}{2}[/tex]
[tex]y = 6[/tex]
Solving (b):
The value of RS
Substitute 6 for y in [tex]RS = 6y +2[/tex]
[tex]RS = 6 * 6 + 2[/tex]
[tex]RS = 36 + 2[/tex]
[tex]RS = 38[/tex]
The value of ST
Substitute 6 for y in [tex]ST=5y + 9[/tex]
[tex]ST = 5 * 6 + 9[/tex]
[tex]ST = 30 + 9[/tex]
[tex]ST = 39[/tex]
The value of ST
Substitute 6 for y in [tex]RT= 13y - 1[/tex]

find the base of isolation triangle whose area is 60 CM square and length of one of its equal side is 13 cm
Answer:
base = 10 cm
Step-by-step explanation:
The height from the vertex is a perpendicular bisector of the isosceles Δ
This line divides the triangle into 2 right triangles with hypotenuse 13
Thus each right triangle is a 5- 12- 13 with legs 5 and 12
The height is 12 cm and the base 5 cm
Then the base of the isosceles Δ = 2 × 5 cm = 10 cm
Note Area = 0.5 × 10 × 12 = 60 cm²

five number are in the ratio 1:2:3:4:5 and the sum is 585.find the numbers
Answer:
39, 78, 117, 156 and 195.
Step-by-step explanation:
If the lowest number is x then we can write the numbers as:
x, 2x, 3x, 4x and 5x, so:
x + 2x + 3x + 4x + 5x = 585
15x = 585
x = 39.
So the second number is 39 * 2 = 78
So all numbers are 39, 78, 117, 156 and 195.

Paul takes a random sample of 50 students in his seventh-grade class and finds that 20 of the students in the sample prefer chocolate ice cream over vanilla ice cream. There are 200 students in the seventh grade. Based on the sample proportion, about how many students in the seventh grade would be expected to prefer chocolate ice cream over vanilla ice cream? 40 80 50 200 I am confused. Please explain a step by step explanation
Answer:
80 students.
Step-by-step explanation:
Since there were 50 students, and 20 students wanted the chocolate icecream, that makes a proportion of 2/5. Then, there are 200 students in this whole seventh grade, and imagine that they have the same proportion of the 50 students. So, you should do 2/5 × 200, and the answer is 80.

An object travels 8 miles in 20 minutes at a constant speed. What is the object's speed in miles per hour
Answer:
24miles/hourStep-by-step explanation:
Speed is the change in distance of a body with respect to time.
Speed = Distance/tIme
Given parameters
Distance = 8miles
TIME = 20minutes
Convert minutes to hour
since 60minutes = 1hr
20 min = x
cross multiply
20 = 60x
x = 20/60
x = 1/3
Hence 20mins = 1/3 hr
Speed = 8miles/(1/3)hr
speed = 8 miles * 3/1 hr
speed = 24 miles/hr
Hence the object's speed in miles per hour is 24miles/hour
The object's speed in miles per hour is 24 miles per hour.
Distance = 8 miles
Time = 20 minutes = 20/60 = 1/3 hour
The speed of an object is calculated as:
= Distance / Time
= 8 ÷ 1/3
= 8 × 3
= 24
In conclusion, the object's speed in miles per hour is 24 miles per hour.
