Answer: The expression for the retail price of a silver chain is 1.4c.
Step-by-step explanation:
Let the amount of jewelry be c dollars.
Rate of mark up = 40%
So, Amount of mark up would be
[tex]\frac{40}{100}[/tex] times c
= 0.4c
So, Amount after mark up would be
c+0.4c
=1.4c
Answer: The expression for the retail price of a silver chain is 1.4c.
O cronograma de vacinação deste posto pretendia vacinar 1500 moradores do bairro, porém não conseguiu vacinar todos os moradores. Qual é a probabilidade de escolher ao acaso um morador do bairro que não tomou a vacina?
Questão completa:
O cronograma de vacinação deste posto pretendia vacinar 1500 moradores do bairro,
porém não conseguiu vacinar todos os moradores. Qual é a probabilidade de escolher
ao acaso um morador do bairro que não tomou vacina?
(eles so conseguiram vascinar 1000 pessoas )
Responda:
1/3
Explicação passo a passo:
Dado que :
Número total de pessoas = 1.500
Número total de vacinados = 1000
Conseqüentemente,
Número de não vacinados = (1500 - 1000) = 500
Portanto, a probabilidade de selecionar aleatoriamente alguém que é vacinado:
Probabilidade = (resultado necessário / número de resultados totais)
P (selecionando alguém que não foi vacinado) =
500/1500
= 1/3 ou 0,3333

Select the correct answer. Which set of coordinates satisfies the equations x − 2y = -1 and 2x + 3y = 12? A. (1, 2) B. (3, 1) C. (3, 2) D. (-3, -2) E. (3, -2)
Answer:
The coordinates that satisfy the equations will be: (3, 2)
Hence, option C is correct.
Step-by-step explanation:
Given the equations
[tex]x\:-2y\:=-1;\:2x\:+\:3y=12[/tex]
solving the equations to find the solution values (coordinates)
[tex]\begin{bmatrix}x-2y=-1\\ 2x+3y=12\end{bmatrix}[/tex]
[tex]\mathrm{Multiply\:}x-2y=-1\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:2x-4y=-2[/tex]
[tex]\begin{bmatrix}2x-4y=-2\\ 2x+3y=12\end{bmatrix}[/tex]
[tex]2x+3y=12[/tex]
[tex]-[/tex]
[tex]\underline{2x-4y=-2}[/tex]
[tex]7y=14[/tex]
so
[tex]\begin{bmatrix}2x-4y=-2\\ 7y=14\end{bmatrix}[/tex]
solve for y
[tex]7y=14[/tex]
[tex]y=2[/tex]
[tex]\mathrm{For\:}2x-4y=-2\mathrm{\:plug\:in\:}y=2[/tex]
[tex]2x-4\cdot \:2=-2[/tex]
[tex]2x=6[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}2[/tex]
[tex]\frac{2x}{2}=\frac{6}{2}[/tex]
[tex]x=3[/tex]
[tex]\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}[/tex]
[tex]x=3,\:y=2[/tex]
Therefore, the coordinates that satisfy the equations will be: (3, 2)
Hence, option C is correct.

A movie theater has a seating capacity of 249. The theater charges $5.00 for children, $7.00 for students, and $12.00 of adults. There are half as many adults as there are children. If the total ticket sales was $ 1806, How many children, students, and adults attended?
9514 1404 393
Answer:
126 children63 adults60 studentsStep-by-step explanation:
Let a represent the number of adults that attended. Then 2a is the number of children, and (249 -a -2a) is the number of students. The total revenue is ...
5(2a) +7(249 -3a) +12a = 1806
a +1743 = 1806 . . . . simplify; next, subtract 1743
a = 63 . . . . . . . . adults
2a = 126 . . . . . . children
249 -3a = 60 . . students
126 children, 63 adults, and 60 students attended.
Payton uses 1 1/2 cups of vinegar in her salad dressing recipe. How much vinegar would Payton use to make 4 2/3 recipes? Plsssssssssssssssss hurryyyyyyyyyy
Answer: 3 1/9 cups of vinegar
Step-by-step explanation:
From the question, we are informed that Payton uses 1 1/2 cups of vinegar in her salad dressing recipe.
To know how much vinegar Payton would use to make 4 2/3 recipes, we divide 4 2/3 by 1 1/2. This will be:
= 4 2/3 ÷ 1 1/2
= 14/3 ÷ 3/2
= 14/3 × 2/3
= 28/9
= 3 1/9 cups of vinegar

A group of 44 students is planning a train trip to Washington, D.C. They held many fundraisers and raised $10,880. Nathan said, “We should have enough money to pay for the train tickets. There are about 50 students going on the trip and one round trip ticket costs about $200. That makes the total cost of the tickets less than $10,000.” Does Nathan’s reasoning make sense?
Answer:
Yes
Step-by-step explanation:
Yes, Nathan's reasoning makes perfect sense because he is only stating that the money will be enough for the train tickets. Since a ticket for a single student is $200 round-trip and there are a total of 50 students going then that would mean that the total cost is indeed $10,000 (200 * 50). Since they raised a total of $10,880 with the fundraisers that would leave them with $880 ($10,880 - $10,000) after buying all the tickets that they need for all of the students.

Point F' is the image when point F is reflected over the line x= -2 and then over the line y = 3.
The location of F' is (3,7).
Which of the following is the location of point F?
A (-7,-1)
B (1,5)
C (1,7)
D (-7,7)
Answer:
Step-by-step explanation:
1. Graph the points
2. Connect the point 3,7
3. Reflect it over line x=-2 and y=3
THE ANSWER IS A (-7,-1)
The location of the point F should be considered as the option A. (-7,-1).
Calculation of the location:Since Point F' is the image when point F is reflected over the line x= -2 and then over the line y = 3. The location of F' is (3,7).
So here we have to do graph the points, then connected the points i.e. 3 and 7. And, then reflect it over the line i.e. x = -2, and y = 3
So here the answer should be (-7,-1)

What single decimal multiplier would you use to increase by 4% followed by a 4% decrease?
Answer:
if you increase by 4%, it means you will have a new total of 104%. In decimals it is 1.04 (divide your percentage by 100) after that you do the same with the 3% increase. you'll have a new total of 103%. In decimals 1.03. If you want to know what single multiplier you can use, you need to multiply the both decimals. So you get 1.04 x 1.03 = 1.0712
Step-by-step explanation:
The decimal multiplier would you use to increase by 4% followed by a 4% decrease is 1.0816.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
We have to find decimal multiplier would you use to increase by 4% followed by a 4% decrease.
So, (1+ 4%)(1+ 4%)
= (1 + 4/100)(1 + 4/100)
= (1 + 0.04)(1+0.04)
= 1.04 x 1.04
= 1.0816

Step-by-step explanation:
for x=5 for x=1/5
Apply;fraction:cross:multiply: 8/12=10/3 x then switch sides
8*3x =12*10 10/3 x = 8/12 cancel the common factor:4
simplify: 10/3 x = 2/3
24x=120 multiply both sides by 3
divide both sides by 24 3*10/3 x = 2*3/3
24x/24=120/24 simplify: 10x =2
simplified =5 divide both sides by 10: 10x/10=10/2
x=5 simplified = 1/5
