LCM is 240
GCF is 6
long explanation
Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor.
LCM(a,b) = ( a × b) / GCF(a,b)
We will now calculate the prime factors of 30 and 48, than find the greatest common factor (greatest common divisor (gcd) of the numbers by matching the biggest common factor of 30 and 48.
Step-1: Prime Factorization of 30
30 = 2^1 × 3^1 × 5^1
Step-2: Prime Factorization of 48
48 = 2^4 × 3^1
Step-3: Factors of 30
1, 2, 3, 5, 6, 10, 15
Step-4: Factors of 48
1, 2, 3, 4, 6, 8, 12, 16, 24
Final Step: Biggest Common Factor Number
We found the factors and prime factorization of 30 and 48. The biggest common factor number is the GCF number.
So the greatest common factor 30 and 48 is 6.

The scale factor of 1 inch = 150 miles is 1/150.
Option D is the correct answer.
What is a scale factor?A scale factor is defined as the ratio between the scale of a new object and the scale of the original object,
We have,
1 inch = 150 miles
150 miles is the original dimension
1 inch is the new dimension
Now,
Scale factor.
= New dimension / Original dimension

Answer:
D. [tex]Rate = -\frac{49}{4}^{\circ} /\frac{7}{2}\ hr[/tex]
Step-by-step explanation:
Given
[tex]T_1 =0^{\circ}[/tex]
[tex]T_2 =-12\frac{1}{4}^{\circ}[/tex]
[tex]Time = 3\frac{1}{2}\ hr[/tex]
Required
Determine the change in temperature per hour
This is calculated as:
[tex]Rate = \frac{T_2 - T_1}{Time}[/tex]
[tex]Rate = \frac{-12\frac{1}{4}^{\circ} - 0^{\circ}}{3\frac{1}{2}\ hr}[/tex]
[tex]Rate = \frac{-12\frac{1}{4}^{\circ} }{3\frac{1}{2}\ hr}[/tex]
Convert to improper fractions
[tex]Rate = \frac{-\frac{49}{4}^{\circ} }{\frac{7}{2}\ hr}[/tex]
Express as:
[tex]Rate = -\frac{49}{4}^{\circ} /\frac{7}{2}\ hr[/tex]

Answer:
1st Square - 1.65
2nd Square - 0.546
3rd Square - 0.546
4th Square - 2000
(got it right on edmentum)
for better understanding of what I mean please take your time to look at the picture below↓Step-by-step explanation:
The margin of error for the 90% confidence interval with a probability of success of 0.546 is 0.0183.
What is the margin of error?The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.
Jamie is an analyst at an education technology company. She gathered data on the results of a certain type of question. Of the 2,000 responses she looked at, 1,092 responded correctly.
Then the value of p will be

And the z-value for the 90% confidence interval will be
[tex]\rm z = 1.645[/tex]
And N = 2000
Then the margin of error (ME) will be
[tex]ME = z \times \sqrt{\dfrac{p(1-p)}{N}}\\\\ME = 1.645\times \sqrt{\dfrac{0.546(1-0.546)}{2000}}\\\\ME = 0.0183[/tex]

Answer:
$37623.04
Step-by-step explanation:
The formula we'll use for this is the simple interest formula, or:
[tex]I=p*r*t[/tex]
Where:
P is the principal amount, $1088.00.
r is the interest rate, 839.5% per year, or in decimal form, 839.5/100=8.395.
t is the time involved, 4....year(s) time periods.
So, t is 4....year time periods.
To find the simple interest, we multiply 1088 × 8.395 × 4 to get that:
The interest is: $36535.04
Usually now, the interest is added onto the principal to figure some new amount after 4 year(s),
or 1088.00 + 36535.04 = 37623.04.
Celso's house is on the market for $220,000. Last year is was on the market for $240,000 but didn't sell. What is the percent decrease in the price of his house
Answer:
91.66666666666667
Step-by-step explanation:
240,000/100 = 220,000/x
220,000 x 100 = 22,000,000
22,000,000 divided by 240,000 = 91.66666666666667
Answer:
This type of problem requires you to calculate the Percentage decrease
Step-by-step explanation:
Formula: Percentage Decrease=
Starting Value minus Final Value / Starting Value x 100
240,000 - 220,000 = 20,000
so 20,000/240,000 = 0.0833333333
so 0.0833333333 x 100 =8.33333333%
ans. 8.33333333% decrease in the price of the house.

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Algebra I
TermsStep-by-step explanation:
Step 1: Define Equation
10x - 6 + 2x = 4(3x - 1) - 2
Step 2: Solve for x
Combine like terms: 12x - 6 = 4(3x - 1) - 2Distribute 4: 12x - 6 = 12x - 4 - 2Combine like terms: 12x - 6 = 12x - 6Add 6 on both sides: 12x = 12xDivide 12 on both sides; x = xHere we see that x does indeed equal x.
∴ any value x would work as a solution to the equation, hence we have infinite amount of solutions.
Answer:
The answer is infinite.
Step-by-step explanation:
So if you first simplify the problem you would have:
12x - 6 = 4 ( 3x - 1 ) - 2
I just combined like terms.
Then you distribute the 4 to the 3x and the negative 1.
So you would have 12x - 6 = 12x - 4 - 2
So once again you would combine like terms and get 12x - 6 = 12x - 6
If you simplified it out and subtracted like terms from both sides you would get 0 = 0 which is true so there is infinite solutions.

Answer:
Step-by-step explanation:Triangles can be classified by their sides and by their angles. When classifying a triangle by its sides, you should look to see if any of the sides are the same length. If no sides are the same length, then it is a scalene triangle. If two sides are the same length, then it is an isosceles triangle.

jeremiah makes 4/5 of the free throw shots he attempts in basketball. Jeremiah likes to shoot free throws until he misses one. Let F be the number of shots it takes Jeremiah to miss his first free throw. Assume that the results of each shot are independent.
Answer:
Mean - 5
Standard Deviation - 4.5
Step-by-step explanation:
Just got it correct on Khan Academy :)
80% is her free throw shooting percentage.
What is Fraction?A fraction represents a part of a whole.
We can construct a fraction in which the numerator is how many shots she makes, and the denominator is how many shots she took overall.
We now have the following fraction:4/5
To convert this to a percentage, we want the denominator to be 20/20
4/5×20/20
80/100
0.8
Now multiply 0.8 with 100
0.8×100=80
Hence, 80% is her free throw shooting percentage.
