At a campground, a rectangular fire pit is 3 feet by 2 feet. What is the area of the largest circular fire that
can be made in this fire pit? Use 3.14 for it. Round to the nearest square Inch.
The area of the largest circular fire pit is 452 square inches.
Explanation:
Given that at a campground, a rectangular fire pit is 3 feet by 2 feet
The radius is given by 1 feet.
Area:
The area of the largest circular fire is given by
[tex]A=\pi r^2[/tex]
Substituting the values in the formula, we get,
[tex]A=(3.14)1^2[/tex]
[tex]A=3.14 \ ft^2[/tex]
Thus, the area of the largest circular fire is 3.14 square feet.
To convert feet to inches:
The feet can be converted into inches by multiplying by 12.
Thus, we have,
[tex]1 \ft= 12 \ inches[/tex]
Hence, we have,
[tex]Area= 3.14\times 12^2[/tex]
Simplifying,we get,
[tex]Area= 3.14\times144[/tex]
[tex]Area=452.16 \ in^2[/tex]
Rounding off to the nearest square inch.
Thus, we have,
[tex]Area= 452 \ in^2[/tex]
Thus, the area of the largest circular fire pit is 452 square inches.

Find the sum of the interior angles of a decagon
Answer:
1440 degrees
Step-by-step explanation:
The sum of the interior angles of a polygon can be found by
(n-2)*180
where n is the number of sides
a decagon has 10 sides, so n=10
(10-2) *180
8*180
1440
The sum of all the interior angles of a decagon is calculated as (n-2) × 180°. For a decagon, where n is 10, the sum is 1440°.
The correct option is (C).
The sum of all the interior angles of a decagon can be found using the formula for calculating the sum of interior angles of any polygon, which is (n-2) × 180°, where n is the number of sides of the polygon. In the case of a decagon, n is 10. Therefore, the sum of all the interior angles of a decagon is (10-2) × 180° = 8 × 180° = 1440°. Thus, the correct answer is C.1440°.

people gathered to watch a baseball game.
While talking, they realized that 11
of them were Toronto Blue Jays fans.
What is the probability that a randomly selected person from the group is a Toronto Blue Jays fan?
Type the answer in simple fraction form.
Answer: 11/30
Step-by-step explanation: looking at this question that was given to us and to find the probability, then we will go by saying that;
Probability of an event (E) = number of outcome of Event E/total number of all event
Prob(Basebase player)=11/30
Going by this, then we are going to have our answer as 11/30
The probability that a randomly selected person from the group is a Toronto Blue Jays fan is 11/30.
Explanation:The question asks for the probability that a randomly selected person from the group of 30 people at a baseball game is a Toronto Blue Jays fan, given that 11 out of the 30 people are fans of that team. To calculate the probability, you divide the number of Blue Jays fans by the total number of people in the group.
Number of Toronto Blue Jays fans: 11Total number of people: 30Probability = Number of Toronto Blue Jays fans ÷ Total number of people
Probability = 11 ÷ 30
The probability can be simplified into the simple fraction form of:
Probability = 11/30
Use the Distributive Property to solve the equation
4(x+2)=16
Answer:
Step-by-step explanation:
4(x+2) = 16
4x + 8 = 16
4x =16-8
4x = 8
x = 8/4
x = 2
The solution to the equation 4(x + 2) = 16 is x = 2.
The Distributive Property states that a(b + c) = ab + ac. Apply this to the equation:
4(x + 2) = 4 * x + 4 * 2.
Thus, the equation becomes:
4x + 8 = 16.
To solve for x, first subtract 8 from both sides of the equation:
4x + 8 - 8 = 16 - 8
4x = 8.
Divide both sides of the equation by 4:
4x / 4 = 8 / 4
x = 2.

Answer: [tex](-9,-3)[/tex]
Step-by-step explanation:
Given the following system of equations:
[tex]\left \{ {{2x=-78-20y} \atop {-x=-51-20y}} \right.[/tex]
In order to solve the System of equations, you can use the Substitution method. The steps are:
1. You can solve for "x" from the second equation:
[tex]-x=-51-20y\\\\x=51+20y[/tex]
2. Substitute the equation obtained into the first original equation:
[tex]2x=-78-20y\\\\2(51+20y)=-78-20y[/tex]
3. Now you must solve for "y":
[tex]102+40y=-78-20y\\\\40y+20y=-78-102\\\\60y=-180\\\\y=\frac{-180}{60}\\\\y=-3[/tex]
4. Substitute the value of "y" into the equation [tex]x=51+20y[/tex] and evaluate:
[tex]x=51+20(-3)\\\\x=51-60\\\\x=-9[/tex]
Then, the solution is:

Write two different mixed numbers where the LCD (lowest common denominator) is 12
Two mixed numbers as [tex]\frac{5}{6}[/tex] and [tex]\frac{5}{12}[/tex] the least common denominator (LCD) is 12.
Step-by-step explanation:
The least common denominator (LCD) is the smallest number that can be a common denominator for a set of fractions. Also known as the lowest common denominator, it is the lowest number you can use in the denominator to create a set of equivalent fractions that all have the same denominator.
Steps to find the LCD of fractions, integers and mixed numbers:
Convert integers and mixed numbers to improper fractionsFind the LCD of all the fractionsRewrite fractions as equivalent fractions using the LCDLet's us have two mixed numbers as [tex]\frac{5}{6}[/tex] and [tex]\frac{5}{12}[/tex].
Equivalent Fractions with the LCD
[tex]\frac{5}{6}[/tex] = [tex]\frac{10}{12}[/tex]
[tex]\frac{5}{12}[/tex] = [tex]\frac{5}{12}[/tex]
For the denominators (6, 12) the least common multiple (LCM) is 12. Therefore, the least common denominator (LCD) is 12.
Final answer:
The mixed numbers 1 1/4 and 2 1/3 can be converted to have the lowest common denominator of 12, resulting in 1 3/12 and 2 4/12 respectively.
Explanation:
To write two different mixed numbers where the lowest common denominator (LCD) is 12, we can choose denominators that are factors of 12 and numerators that result in proper fractions (where the numerators are less than the denominators). An example would be 1 1/4 and 2 1/3. Here's how these mixed numbers have 12 as their common denominator:
For 1 1/4, the denominator 4 is a factor of 12. To convert 1/4 to a denominator of 12, multiply the numerator and denominator by 3. So, 1 1/4 becomes 1 3/12.For 2 1/3, the denominator 3 is also a factor of 12. To convert 1/3 to a denominator of 12, multiply the numerator and denominator by 4. So, 2 1/3 becomes 2 4/12.Now we have two mixed numbers with the LCD of 12.

Y=3x+13
Y=x-3
Answer:
x = -8
Y = -11
Step-by-step explanation:
Given
Y = 3x + 13
Y = x - 3
Substitute x - 3 for Y in the first equation
We have
Y = 3x + 13
x - 3 = 3x + 13
Add 3 to both sides
x - 3 + 3 = 3x + 13 + 3
x = 3x + 16
Subtract 3x from both sides
x - 3x = 3x - 3x + 16
-2x = 16
Divide both sides by -2
x = 16/-2
x = -8
Now substitute -8 for x in any of the above equations to get Y.
Using the second equation, we have
Y = x - 3
Y = -8 - 3
Y = -11

what are the factors of x^2 – 100?
Answer:
(x - 10)(x + 10)
Step-by-step explanation:
x² - 100 is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
Thus
x² - 100
= x² - 10²
= (x - 10)(x + 10)
The expression x² - 100 can be factored using the difference of squares rule in algebra. The factors are (x - 10) and (x + 10).
Explanation:
The question asks for the factors of the polynomial expression x² – 100. This is a special kind of polynomial that can be factored using the difference of squares rule, a powerful tool in algebra which states that any expression in the form a² - b² can be rewritten as (a - b)(a + b).
In our case, a would be x (since x² is the first term) and b will be 10 (since 10² equals 100, the second term).
Applying the difference of squares rule to your expression, we get:
x² – 100 = (x - 10)(x + 10)
The factors of the expression are therefore x - 10 and x + 10.

Step-by-step explanation:
The n th term of a geometric sequence is
[tex]a_{n}[/tex] = a[tex](r)^{n-1}[/tex]
where a is the first term and r the common ratio
Here a = 15, thus
[tex]a_{5}[/tex] = 15[tex](r)^{4}[/tex] = [tex]\frac{243}{125}[/tex] ( divide both sides by 15 )
[tex]r^{4}[/tex] = [tex]\frac{243}{1875}[/tex], thus
r = [tex]\sqrt[4]{\frac{243}{1875} }[/tex] = [tex]\frac{3}{5}[/tex]
Multiply the previous term by [tex]\frac{3}{5}[/tex] to obtain the next term
15 × [tex]\frac{3}{5}[/tex] = 9
9 × [tex]\frac{3}{5}[/tex] = [tex]\frac{27}{5}[/tex]
[tex]\frac{27}{5}[/tex] × [tex]\frac{3}{5}[/tex] = [tex]\frac{81}{25}[/tex]
[tex]\frac{81}{25}[/tex] × [tex]\frac{3}{5}[/tex] = [tex]\frac{243}{125}[/tex]
Thus the sequence is
15, 9, [tex]\frac{27}{5}[/tex], [tex]\frac{81}{25}[/tex], [tex]\frac{243}{125}[/tex]
