c=30+50
c=80
Answer: C, c = $80
Step-by-step explanation:
c = 3h + 50

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.

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.

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

Which one of the following does not describe Aaron Burr?
made unwise decisions
was wanted for murder in two states
led the Senate
had a law practice
a brilliant politician
Answer:
Aaron Burr wasn't a brilliant politician.
Step-by-step explanation:
Aaron Burr was an American politician and the third Vice President of the United States from 1801 to 1805. In 1800, he ran for the Democratic-Republicans with Thomas Jefferson. Jefferson was supposed to be president and Burr vice president, but the then presidential election rules gave Jefferson and Burr equal votes in the Electoral College, and the election was ultimately decided in the House of Representatives. There, it were Jefferson and Burr's political rivals, the Federalists, who made the difference. Alexander Hamilton, the leader of the Federalists, eventually urged his party to back Jefferson, which helped make Hamilton and Burr deadly rivals. Burr had to settle for vice president under Jefferson.
On July 11, 1804, Burr challenged Hamilton to a duel in which Burr would fire the deadly shot. Burr was charged with murder in two states, but never prosecuted. After a short flight south, Burr returned to Washington to serve his term as vice president.
After his term, Burr was suspected of involvement in a plot to create a separate republic in the then Southwestern US, headed by himself. For this he was arrested in 1807. He was tried for treason but was acquitted. After a stay abroad, Burr returned to New York in 1812 and resumed his career as a lawyer. He died in 1836 at the age of eighty and was buried in Princeton, New Jersey.
