To find the LCM of the denominators 8 and 32, we prime factorize them, identify the highest power of each prime number, and multiply these together. The LCM of 8 and 32 is 32.
To find the Least Common Multiple (LCM) of the denominators from the fractions 6/8 and 4/32, follow these steps:
Identify the denominators: 8 and 32.
Prime factorize each denominator:
8 = 2 × 2 × 2 (2³)32 = 2 × 2 × 2 × 2 × 2 (2⁵)Identify the highest power of each prime number that appears in the factorizations. Here, the highest power of 2 is 2⁵.
Multiply the highest powers of all the primes together to find the LCM: LCM = 2⁵ = 32.
So, the LCM of the denominators 8 and 32 is 32.

How do i find quartiles, 1,2 and 3
Lower quartile=25% of total frequency/numbers in the data set
Median=50% of total frequency/numbers in the data set
Upper quartile=75% of total frequency/numbers in the data set
Hope this helps:)
Answer:
see explanation
Step-by-step explanation:
To obtain the quartiles arrange the data in ascending order
38, 47, 54, 60, 67, 68, 76, 77, 84, 89
Q₂ is the median
The median is the middle value in the data set. If there is no exact middle value then it is the average of the 2 values either side of the middle
Q₂ = [tex]\frac{67+68}{2}[/tex] = 67.5
Q₁ is the lower quartile and is the middle value of the data to the left of the median
Q₁ = 54
Q₃ is the upper quartile and is the middle value of the data to the right of the median
Q₃ = 77

a fish tank is shaped like a rectangular prism. It has a length of 5 feet, a width of 2 feet, and a height of 3 feet. what is the volume of the fish tank?
Answer:
30 ft
Step-by-step explanation:
It is 30 because to find the volume of a rectangular prism, you do
length x width x height.
So, 5 x 2 x 3 = 30.
To find the volume of a rectangular prism, multiply its length, width, and height. Thus, the volume of the fish tank measuring 5 feet in length, 2 feet in width, and 3 feet in height is 30 cubic feet.
Explanation:The volume of a rectangular prism such as a fish tank can be calculated by multiplying its length, width, and height together. For a fish tank with a length of 5 feet, a width of 2 feet, and a height of 3 feet, the volume calculation would look like this:
Volume = Length × Width × Height
Volume = 5 ft × 2 ft × 3 ft
Volume = 10 ft × 3 ft
Volume = 30 ft³
Therefore, the volume of the fish tank is 30 cubic feet.

Answer:
A: 700
B: 6400
C: 50
Step-by-step explanation:
A: You can multiply by 5
B: You can just multiply by 20.
C: Every 10% is 5, because 15(30%)/3 is 5. 5 times 10 is 50.
Answer:
a. h = 700
b. j = 6400
c. g = 50
Step-by-step explanation:
Translate each statement into an equation and solve the equation. Remember that to change a percent to a decimal, you divide the percent by 100, which is the same as moving the decimal point two places to the left. Also, a percent of a number means a percent times the number.
a. 20% of h is 140
20% * h = 140
0.2h = 140
Divide both sides by 0.2
h = 700
b. 5% of j is 320
5% * j = 320
0.05j = 320
Divide both sides by 0.05
j = 6400
c. 30% of g is 15
30% * g = 15
0.3g = 15
Divide both sides by 0.3
g = 50

A coin is tossed twice. Let H represents heads, T represents tails, and the combination of the two letters represent the outcome of both tosses (e.g., if the coin landed heads on the first toss and tails on the second, we'd represent that with HT). Which of the following sets includes all possible outcomes of both tosses?
Answer:
{HH, HT, TH, TT}
Step-by-step explanation:
The set of all possible outcomes in tossing a coin twice is;
{HH, HT, TH, TT}
In the first toss the coin may land Heads. In the second toss the coin may land Heads or Tails. This can be represented as;
HH, HT
Heads in the first and second tosses. Heads in the first toss followed by a Tail in the second toss.
In the first toss the coin is also likely to land Tails. In the second toss the coin may land Heads or Tails. This can be represented as;
TH, TT
Tails in the first toss followed by a Head in the second toss. Tails in the first and second tosses.
Combining these two possibilities will give us the set of all possible outcomes in tossing a coin twice is;
{HH, HT, TH, TT}

Terri wrote the equation using slope-intercept form for the line that passes through the points (4, 6) and (–2, 3).
Which best describes Terri’s first error?
In step 1, the slope of the line should be 1/2.
In step 2, she should have substituted the point (4, 6).
In step 3, she should have subtracted 4 from both sides of the equation.
In step 4, the m and b values should be switched.
Answer:
Step 1 is incorrect.
Step-by-step explanation:
The slope = difference of y values / difference of x values so Step 1 is incorrect. The slope is (6-3)/ ((4 - (-2)) = 1/2. He worked out x differences / y differences.
Answer: A: In step 1, the slope of the line should be 1/2.
Find area of a cone
Show work
Answer: 138.16 in²
Step-by-step explanation:
You need to use this formula to calculate the surface area of the cone:
[tex]SA = \pi r^2 + \pi rl[/tex]
Where "r" is the radius, "h" is the height and "l" is the slant height.
To find the height you need to use the Pythagorean Theorem:
[tex]a^2=b^2+c^2[/tex]
Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.
In this case:
[tex]a=l=7in\\\\b=r=\frac{8in}{2}=4in\\\\c=h[/tex]
("r" is the radius and "h" is the height and "l" is the slant height.)
You need to find "h". Then, solving for "h", you get:
[tex]h=\sqrt{(7in)^2-(4in)^2}\\h=5.74in[/tex]
Then, substituting values into the formula, you get:
[tex]SA = (3.14)(4in)^2 + (3.14) (4in)(7in)=138.16in^2[/tex]

Step-by-step explanation:
Expand the expression (5x + 3)2, and write the result in standard form.
Expand
2 × 5x + 2 × 3
Simplify 2 × 5x to 10x
10x + 2 × 3
Simplify 2 × 3 to 6
= 10x + 6
The expanded expression in standard form for the given equation is [tex]\(25x^2 + 30x + 9\).[/tex]
To expand the expression [tex]\((5x + 3)^2\)[/tex], we use the distributive property, which states that for any real numbers [tex]\(a\), \(b\), and \(c\):[/tex]
[tex]\((a + b)^2 = a^2 + 2ab + b^2\).[/tex]
In this case,[tex]\(a = 5x\)[/tex] and[tex]\(b = 3\)[/tex]. Substituting these values into the formula, we get:
[tex]\[(5x + 3)^2 = (5x)^2 + 2(5x)(3) + 3^2\][/tex]
Now, let's compute each term:
1.[tex]\( (5x)^2 = 25x^2 \) (since \((a)^2 = a \times a\)).[/tex]
2. [tex]\(2(5x)(3) = 30x\) (by multiplying \(2ab\) where \(a = 5x\) and \(b = 3\)).[/tex]
3. [tex]\(3^2 = 9\).[/tex]
Now, summing up all the terms, we get:
[tex]\[ (5x + 3)^2 = 25x^2 + 30x + 9 \][/tex]
So, the expanded expression in standard form is [tex]\(25x^2 + 30x + 9\).[/tex]

letters on the bill have been received and
323 of these oppose the bill. What is the
sample size?
A. 684
B. 38
C. 361
D. 323
Answer:361
Step-by-step explanation:
The sample size in this scenario is defined by the total number of letters received by the member of Congress, regardless of their stance on the bill. Therefore, the sample size is 361.
Explanation:In statistics, the term 'sample size' refers to the number of observations or measurements used in a study or experiment. In this particular case, the member of Congress is interested in the views of her constituents on a proposed gun-control bill. The total number of letters received - regardless of whether those letters support or oppose the bill - forms the sample size.
In this context, the total number of letters is 361, so option C is the correct answer. It doesn't matter how many of these letters were in favor or against the bill; all of them constitute the sample. The number of letters opposing the bill (323) is a part of the total sample, not the sample size itself.

One cell phone plan charges $20 per month plus $0.15 per minute used. A second cell phone plan charges $35 per month plus $0.10 per minute used. Write and slice an equation to find the number of minutes you must talk to have the same cost for both calling plans.
Answer:
300 minutes
Step-by-step explanation:
Let
x----> the numbers of minutes used
y ---> the cost per month
we know that
First cell phone plan
y=0.15x+20 ---> equation A
Second cell phone plan
y=0.10x+35 ---> equation B
equate the equation A and equation B
0.15x+20=0.10x+35
Solve for x
0.15x-0.10x=35-20
0.05x=15
x=15/0.05
x= 300 minutes
Find the cost y
y=0.15(300)+20 =$65
That means
For x=300 minutes
The cost for both calling plans is y=$65
