Given:
The selling price of a ratio set = 72.00
Profit percent = 8%
To find:
The cost price for the radio set.
Solution:
Let x be the cost price for the radio set.
Radio set is sold at 8% profit.
[tex]\text{Selling price}=x+\dfrac{8}{100}x[/tex]
[tex]\text{Selling price}=x+0.08x[/tex]
[tex]\text{Selling price}=1.08x[/tex]
The selling price of a ratio set is 72.00.
[tex]72=1.08x[/tex]
[tex]\dfrac{72}{1.08}=x[/tex]
[tex]x=66.666...[/tex]
[tex]x\approx 67[/tex]
Therefore, the cost price for the radio set is 67.

4. The Bulldog Theater charges $9.10 for each adult ticket and $7.75 for each student ticket. Mrs. Williams purchased 7 tickets (some students and some adult) for $56.95. Which system of equations could be used to find a, the number of adult tickets, and s, the number of student tickets purchased?
Answer:
Two adult tickets and 5 student tickets
Step-by-step explanation:
Let a=adult tickets Let s=student tickets
You know that each adult ticket is $9.10 and each student ticket cost $7.75. At the end, it cost $56.95 for both students and adults so the first equation should be 9.10a+7.75s=56.95. To get the second equation, you know that Mrs. Williams purchased 7 tickets in total that were both students and adults. Therefore, the second equation should be a+s=7. The two equations are 9.10a+7.75s=56.95
a+s=7.
Now, use substitution to solve this. I will isolate s from this equation so the new equation should be s=-a+7. Plug in this equation to the other equation, it will look like this 9.10a+7.75(-a+7)=56.95. Simplify this to get 9.10a-7.75a+54.25=56.95. Simplify this again and the equation will become 1.35a=2.70. Then divide 1.35 by each side to get a=2. This Mrs. Williams bought two adult tickets. Plug in 2 into a+s=7, it will look like this (2)+s=7. Simplify this and get s=5. This means Mrs. Williams bought five adult tickets. Therefore she bought 2 adult tickets and 5 student tickets.
Hope this helps
Would be great if someone could solve this for me I’m not too sure how to do it .

Mr. Carlevato and Mr. Burrows get into a debate about two different expressions. · Mr. Carlevato says "2(2x + 3) is equal to 4x + 6". · Mr. Burrows says "Nope, wrong, those are clearly different expressions" Try substituting x=5 into both expressions. Do you get the same answer for both expressions? Show your work!
Answer:
Yes, the same answer is obtained.
Step-by-step explanation:
According to Mr. Carlevato, [tex]2(2x+3)[/tex] is equal to [tex]4x+6[/tex]. However, [tex]2(2x+3)[/tex] is not equal to [tex]4x+6[/tex] according to Mr. Burrows.
Put [tex]x=5[/tex] in [tex]2(2x+3)[/tex]
[tex]2[2(5)+3]=2(10+3)=2(13)=26[/tex]
Put [tex]x=5[/tex] in [tex]4x+6[/tex]
[tex]4x+6=4(5)+6=20+6=26[/tex]
Therefore,
[tex]2(2x+3)=4x+6[/tex]
Yes, the same answer is obtained.
The downtown trolly travels around town on a rectangular route stopping at 4 different tourist destinations if the length of the rought was 5.5 miles and the with was 4 miels how far is one complete trip anser
Answer:
19 miles
Step-by-step explanation:
Given that :
Shape of route is rectangular :
Length of route = 5.5 miles
Width of route = 4 miles
Distance of one complete trip = perimeter of the rectangular route :
Perimeter of a rectangle :
P = 2(length + Width)
P = 2(5.5 + 4)
P = 2(9.5)
P = 19 miles
Hence one complete trip is 19 miles long.

Step-by-step explanation:
Last year you drove your car 11,452 miles. You kept track of all your expenses for the year.

What was your cost per mile to operate your car?
A swing hangs from a beam 10 feet high, with the seat hanging 2 feet above the ground. In motion, the swing moves back and forth from -130° to -50° to the horizontal. How far forward and back does the swing move along the ground at the extremes?
Answer:
11.17 ft
Step-by-step explanation:
Since the swing hangs from a beam 10 feet high with the seat hanging 2 feet above the ground, the swing moves in an arc of radius r = 10 ft - 2 ft = 8 ft.
Now, since the swing moves back and forth from -130° to -50° to the horizontal, the length of arc L it moves in is given by
L = Δθ/360 × 2πr where Δθ = change in angle of the swing = θ₂ - θ₁ where θ₁ = -50° and θ₂ = -130°. So, Δθ = θ₂ - θ₁ = -130° -(-50°) = -130° + 50° = -80°.
Substituting r and Δθ into L, we have
L = -80°/360° × 2π(8 ft)
= -8/36 × 16π ft
= -32π/9 ft
= -100.53/9 ft
= -11.17 ft
Ignoring the negative sign, the length of arc L = 11.17 ft. So, the swing moves back and forth 11.17 ft
2 numbers a and b vary directly if ab =k, k is a constant is it correct

The value of x is ___, and the value of y is ___.
Answer:
I think x is 60 and y is 50.
Step-by-step explanation:
70 + 50 = 120
180 - 120 = 60
x = 60
50 + 50 = 100
70 + 60 = 130
130 + 100 = 230
230 - 180 = 50
y = 50
I hope this helps u! :D
Answer:
x=60 y=50
Step-by-step explanation:
180 is equal to the whole triangle so 50+70=120 and 180-120= 60
the other triangle has a missing value by doing the same thing before we can figure out that the missing value is 70. 70+x which is 60 equals 130. A straight line is equal to 180 so 180-130= 50.
Hope I could help!
Ethan hits 4 ringers in 10 attempts while throwing horseshoes. What does an experimental probability of 2/5 describe?
Your answer:
O P (horseshoes)
O P (missed shots)
O P (attempts)
O P (ringers)
Answer: P (ringers)
Step-by-step explanation:
This probability is simplified from 4/10 to 2/5
Since he got 4 ringers out of 10 attempts
we can tell that this probability stands for Ringers

Answer:
[tex]\Huge\boxed{x=53}[/tex]
Step-by-step explanation:
Hello There!
Once again we need to use trigonometry to solve for X
Here are the Trigonometric Ratios:
Sin = Opposite divided by hypotenuse
Cos = adjacent divided by hypotenuse
Tan = Opposite divided by adjacent
We are given the adjacent side of x (45) and the hypotenuse (75) so we need to use cos
Remember cos = adjacent divided by hypotenuse
Now we create an equation
[tex]cos(x)=\frac{45}{75}\\\frac{45}{75} =.6[/tex]
now we have
[tex]cos(x)=.6[/tex]
like always we want to get rid of cos
to do so we take the inverse of cos (arccos^-1) and apply that to each side
[tex]arccos^-^1(cos(x))=x\\arccos^-^1(.6)=53.13010235[/tex]
finally we round to the nearest degree
we're left with x = 53
