A number, x, rounded to 1 decimal place is 3.7
Write down the error interval for x.
Answers
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)

Answers
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.

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.
Answers
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.

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]

For starters, algebra is foundational for other classes. That means you’ll apply what you learn in algebra throughout school. Learning algebra helps to develop your critical thinking skills. That includes problem solving, logic, patterns, and reasoning. You need to know algebra for many professions, especially those in science and math. Not planning to go into those fields? You’ll probably still use algebra without even realizing it!
Consider these examples: It’s time to fill up your car’s gas tank. The price of gas per gallon is $3 and you only have $25 to spend. How much gas can you purchase? This can be answered by the algebraic equation, “3x = 25.” You must divide each side of the equation by 3 in order to isolate x. In this equation, x is equal to 25 divided by 3, which is 8.33 gallons of gas. If you need 10 gallons of gas, how much money do you need? When you solve that equation, you have algebra to thank!
There are many other examples of real-world uses of algebra, from comparing prices on similar products in a grocery store to figuring out what time you need to leave your house in order to meet a friend across town on time. If you ever WONDER why you need to learn something like algebra, don’t be afraid to ask your teacher or parent (or Wonderopolis!). Odds are, there’s a good reason!

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?
Answers
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]

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?
Answers
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.
