Elena is making greeting cards, which she will sell by the box at an arts fair. She paid $54 for
a booth at the fair, and the materials for each box of cards cost $9.50. She will sell the cards
for $11 per box.
At some point, she will sell enough cards so that her sales cover her expenses. How much will
the sales and expenses be? How many boxes of cards will that take?
Elena's sales and expenses will both be $
if she sells
boxes of cards.
Submit
Answer:
Elena's sales and expenses will both be $
396
if she sells
36
boxes of cards.
Step-by-step explanation:
The number of greeting cards are 36 and Elena's sales and expenses will both be $396.
Elena paid $54 for a booth at the fair, and the materials for each box of cards cost $9.50.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number of cards be x.
At some point, she will sell enough cards so that her sales cover her expenses.
So, 54+9.50x=11x
⇒ 11x-9.50x=54
⇒ 1.50x=54
⇒ x=54/1.50
⇒ x=36
Thus, sales=expenses= 11x
= 11×36
= $396
Hence, the number of greeting cards are 36 and Elena's sales and expenses will both be $396.

The ratio of dogs to cats in a veterinarian's office is 9:7. What is the ratio of the number of dogs
to the total number of dogs and cats in the veterinarian's office?
Answer:
The ratio of the number of dogs to the total number of dogs and cats in the veterinarian's office is 9:16.
Step-by-step explanation:
Ratio:
The ratio of a to b is given by:
[tex]a:b = \frac{a}{b}[/tex]
The ratio of dogs to cats in a veterinarian's office is 9:7.
This means that for each 9 dogs, there are 7 cars.
What is the ratio of the number of dogs to the total number of dogs and cats in the veterinarian's office?
9 dogs
9 + 7 = 16 dogs and cats. So
The ratio of the number of dogs to the total number of dogs and cats in the veterinarian's office is 9:16.
A can of tomato soup has a circular base with a diameter of 7 cm. If the surface area of the can is 104.3 cm. What is the height of the can?
Answer:
1.243 cm
Step-by-step explanation:
The surface area of a cylinder is the sum of the area of the two congruent circular bases and the rectangular lateral area.
[tex] SA = 2\pi r^2 + 2 \pi rh [/tex]
[tex] SA = 2\pi r(r + h) [/tex]
We are given the surface area and the diameter.
r = d/2 = 7 cm / 2 = 3.5 cm
We can solve for h, the height.
[tex] SA = 2\pi r(r + h) [/tex]
[tex] 2\pi r(r + h) = SA [/tex]
[tex] r + h = \dfrac{SA}{2\pi r} [/tex]
[tex] h = \dfrac{SA}{2\pi r} - r [/tex]
[tex] h = \dfrac{104.3~cm^2}{2(3.14159)(3.5~cm)} - 3.5~cm [/tex]
[tex] h = 1.243~cm [/tex]

Solve (x - 2)^2 - 3 = 1 graphically. That is graph y = (x - 2)^2 - 3 and y = 1 on the same set of axes and find the x-value(s) of any points of intersection. Then use algebraic strategies to solve the equation and verify that your graphical solutions are correct.
Check the attachment(s) for the graphs pertaining to the question
No. 1) Check graph [first attachment]
No. 2) y = (x - 2)^2 - 3, y = 1
(x - 2)^2 - 3 = 1,
(x - 2)^2 = 4
x - 2 = √4, x - 2 = - √4
x = 4, x = 0
Substitute back to determine the respectively y-value:
y = (4 - 2)^2 - 3 = (2)^2 - 3 = 4 - 3 = 1
Check: y = (0 - 2)^2 - 3 = (-2)^2 - 3 = 4 - 3 = 1
So the points of intersection are (4, 1) and (0, 1). According to the graph, that is correct.

A number, x, rounded to 1 decimal place is 3.7
Write down the error interval for x.
Answer: (3.65, 3.74)
Step-by-step explanation:
Now, when we round a number to a given decimal place, we need to look at the decimal to the left of the decimal place where we are rounding.
if it is 5 or more, we round up
if it is smaller than 5, we round down.
Then for example, if we want to round:
4.534
to the first decimal place, we need to look at the second decimal place.
we can see that it is a 2.
Then we round down, and get:
4.5
Now we know that, when rounding to the first decimal place, we have:
x = 3.7
Then the maximum value that x could have is:
x = 3.74 (because here we round down to 3.7)
and the minimum value that x could have is:
x = 3.65 (because here we round up to 3.7)
Then the error interval for x is:
(3.65, 3.74)

You've decided to give your best friend a
bag of marbles for his birthday.
Since you know that your friend likes
green marbles better than red ones, the
bag has twice as many green marbles as
red.
The label on the bag says it contains a
total of 84 marbles.
How many green marbles are in the bag?
Number of green marbles in the bag is equals to [tex]56.[/tex]
What is number?
" Number is defined as the count of any given quantity as per condition."
According to the question,
Given,
Total number of marbles [tex]= 84[/tex]
[tex]'x'[/tex] represents the number of red marbles
As per given condition,
[tex]'2x'[/tex] represents the number of green marbles
Required equation we have,
[tex]x + 2x = 84\\\\\implies 3x =84\\\\\implies x = \frac{84}{3} \\\\\implies x = 28[/tex]
Substitute the value of [tex]'x'[/tex] to get number of green marbles ,
Number of green marbles [tex]2x = 2\times 28[/tex]
[tex]= 56[/tex]
Hence, number of green marbles in the bag is equals to [tex]56.[/tex]

An international company has 25,800 employees in one country. If this represents 31.1% of the companies employees, how many employees does it have in total?
Answer:
Rounded to the nearest integer, the company has a total of 82,958 employees.
Step-by-step explanation:
Given that an international company has 25,800 employees in one country, if this represents 31.1% of the companies employees, to determine how many employees does it have in total, the following calculation must be performed:
31.1 = 25,800
100 = X
100 x 25,800 / 31.1 = X
2,580,000 / 31.1 = X
82,958.1 = X
Thus, rounded to the nearest integer, the company has a total of 82,958 employees.
