Answer:
R = 23.9
Step-by-step explanation:
formula for circles circumfrence is, C = 2*3.14*R
in this one we have to work backwards so we plug wut we have.
150 = 2* 3.14*R
we divide 150 by 2 so it will be
75 = 3.14R
now we divide 75 by pi so wwe get
23.8732414638 = R
Now we round it to nearest tenth
R = 23.9
Whats the product of 2/3 × 36
Answer:
24 :)
Step-by-step explanation:
2 / 3 x 36 = ?
First of all, note that 36 is the same as 36/1 since 36 divided by 1 is 36. Therefore, start by setting up the problem like this:
36 / 1 x 2 / 3
Multiply the numerators together (36 x 2 = 72) and multiply the denominators together (1 x 3 = 3) and make it into one fraction like so:
72 / 3
The greatest common factor of 72 and 3 is 3. Minimize the fraction by dividing the numerator and the denominator by its greatest common factor to get:
24 / 1
Convert the improper fraction above to a whole number to get the answer:
24
Hope this helps :)

The glee club needs to raise money for the spring trip to Europe, so the members are assembling holiday wreaths to sell. Before lunch, they assembled 15 regular wreaths and 15 deluxe wreaths, which used a total of 135 pinecones. After lunch, they assembled 15 regular wreaths and 20 deluxe wreaths, using a total of 160 pinecones. How many pinecones are they putting on each wreath?
Answer:
5 pinecones on the deluxe wreath and 4 pinecones on the regular wreath
Step-by-step explanation:
Answer:
Regular: 4
Deluxe: 5
Step-by-step explanation:
15x + 15y = 135
15x + 20y = 160
5y = 25
y = 5
15x = 135 - 15(5)
15x = 60
x = 4
Grandma says Baby Bertha (BB) should get $1000 at birth plus $50 per year. Grandpa disagrees; he thinks BB should get $1000 at birth plus an additional 4% of the accumulated amount each year. Grandma and Grandpa will continue to contribute additional funds into the account as long as BB doesn’t make a withdrawal. Which option should BB’s parents select? Why?
BB's parents should choose Grandpa's option, where Baby Bertha (BB) receives $1000 at birth plus an additional 4% of the accumulated amount each year.
Explanation:In Grandpa's option, the annual contribution grows dynamically with the accumulated amount, creating compounding growth. Let's denote the accumulated amount at the end of year \(n\) as A_n. The contribution at year \(n\) can be expressed as \(0.04 \times A_n\). BB's total amount at the end of year \(n\) can be written as:
\[A_n = 1000 \times (1 + 0.04)^{n}.\]
This formula considers the initial $1000 and the 4% annual growth on the accumulated amount. With compounding, this option ensures that BB's fund grows significantly over time.
Grandma's option, on the other hand, provides a fixed annual amount of $50, which does not consider the potential growth through interest or investment. Over time, the fixed contribution might not keep up with inflation, and the fund may not accumulate as much as Grandpa's option.
In summary, Grandpa's option is financially advantageous due to compounding growth, allowing BB's fund to grow more substantially over the years. This strategy aligns with long-term financial planning, providing a better financial foundation for Baby Bertha's future.

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.

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,

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]

Thus, we have,
[tex]Area= 452 \ in^2[/tex]
Thus, the area of the largest circular fire pit is 452 square inches.
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.

Make the denominator same
[tex]\frac{4s \times 30 }{30} + \frac{1s \times 5}{6 \times 5} + \frac{13s \times 6}{5 \times 6}\\\\\frac{120s}{30} + \frac{5s}{30} + \frac{78s}{30}\\\\\frac{203}{30} = 6.7667[/tex]

An=a^1*r^n-1 that’s the formula for the equation I kinda dunno how to exactly solve it though
Answer:
see explanation
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]

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

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
A computer programmer worked for 10 hours and earned $70,which is a rate of dollars per hour.
When a programmer works for 10 hours and earns $70, the rate of dollars per hour earned by the programmer is $7.
A computer programmer worked for 10 hours and earned $70.
To calculate the rate per hour, we divide the total earnings by the number of hours worked. In this case,
$70 ÷ 10 hours = $7 per hour.
Therefore, the programmer earned $7 per hour.
