There is a vendor at a carnival selling bags of cotton candy. Each bag of cotton candy has the same cost. She starts each day with a certain amount of money to give change when necessary. After she sells a total of 12 bags, she has $128. After she sells a total of 20 bags, she has $160.
How much does the vendor charge per bag of cotton candy?
Answer:
The cost of each cotton candy bag is $4.
Step-by-step explanation:
Consider the provided information.
Let, the vendor has [tex]x[/tex] dollar at the starting of each day.
Let, the cost of each cotton candy bag is [tex]y[/tex].
Now when she sells a total of 12 bags, she has $128.
[tex]x+12y=128[/tex] .....(1)
After she sells a total of 20 bags, she has $160.
[tex]x+20y=160[/tex] ....(2)
Subtract equation 1 from equation 2.
[tex](x+20y)-(x+12y)=160-128[/tex]
[tex]8y=32[/tex]
[tex]y=4[/tex]
Hence, the cost of each cotton candy bag is $4.

Azucena vende un automóvil en $37,500.00, sin embargo se devalúa el 18% por cuestiones de uso y degradación de los materiales. Determine el precio final de venta.
Answer:
$30,750
Step-by-step explanation:.
Paso uno:
datos dados
costo del auto = $ 37,500
% degradación = 18%
= 18/100 * 37,500
= 0,18 * 37,500
= $ 6750
Segundo paso:
deje que el costo total sea T
Por lo tanto
T = coste del coche-% de degradación
T = 37.500-6750
T = 30,750

Harold earns $10.50 per hour working at a doctor's office. On Monday he spent 1 5/12 hours filing paperwork, 1 3/4 sending emails and 2 1/3 hours making appointments. What were Harold's earnings? Round your answer to the nearest cent.
Answer:
the total earnings is $58
Step-by-step explanation:
The computation of earnings is shown below:
= Time spent in filling paperwork + time spent in sending emails + time spent in making appointments
= (1 5 ÷ 12 × $10.50) + (1 3 ÷ 4 × $10.50) + (2 1 ÷ 3 × $10.50)
= 14.875 + 18.375 + 24.50
= $57.75
Hence, the total earnings is $58
The same is to be considered

Complete the table of values for the function f(x) = (1/3)x for a, b, and c. x : -2, -1, 0, 1, 2. f(x) : a, b, c, 1/3, 1/9
Given:
The function is
[tex]f(x)=\left(\dfrac{1}{3}\right)^x[/tex]
To find:
The missing values for a, b, and c in the given table.
Solution:
We have,
[tex]f(x)=\left(\dfrac{1}{3}\right)^x[/tex]
At x=-2,
[tex]f(-2)=\left(\dfrac{1}{3}\right)^{-2}[/tex]
[tex]a=\left(3\right)^{2}[/tex] [tex]\left[\because \left(\dfrac{a}{b}\right)^{-n}=\left(\dfrac{b}{a}\right)^{n}\right][/tex]
[tex]a=9[/tex]
At x=-1,
[tex]f(-1)=\left(\dfrac{1}{3}\right)^{-1}[/tex]
[tex]b=\left(3\right)^{1}[/tex] [tex]\left[\because \left(\dfrac{a}{b}\right)^{-n}=\left(\dfrac{b}{a}\right)^{n}\right][/tex]
[tex]b=3[/tex]
At x=0,
[tex]f(0)=\left(\dfrac{1}{3}\right)^{0}[/tex]
[tex]c=1[/tex] [tex]\left[\because a^0=1, a\neq 0\right][/tex]
Therefore, the missing values of a,b and c are 9, 3, and 1 respectively.

What is the Pythagorean Theorem? Provide the equation and an explanation as to what it means.
Answer:
The Pythagorean Theorem is a squared + b squared = c squared. It is used to find out a side of a triangle if you already know the two others. C is always the H=hypotenuse, while the other two sides are a and b.
Answer: a^2+b^2 (factored) = c^2
Step-by-step explanation:
This only helps if you are solving for the hypotenuse.
