What is termed as the LCM?LCM is an abbreviation for "Least Common Multiple." The smallest multiple which two or even more numbers have now in common is defined as the least common multiple.The least amount divisible from both numbers is the LCM of two numbers.Discovering the lowest common denominator (LCD) of 2 or more fractions is a common application of LCM.To estimate the one caller to receive the all three prices, find the LCM of 15, 25 and 100.
LCM of 15, 25 and 100 is as follows;
3 15, 25, 100
----------------------
4 5, 25, 100
-----------------------
5 5, 25, 25
----------------------
5 1, 5, 5
-----------------------
1, 1, 1
LCM = 3×4×5×5
LCM = 300
Therefore, the radio station will first award all three prizes to the 300th caller.

Find the geometric mean between each pair of numbers.
18 and 1.5
Answers
The geometric mean between the pair of numbers, 18 and 1.5, is 3√3.
Geometric mean, like arithmetic mean, is a kind of average and a measure of central tendency.
To solve for the geometric mean, we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. In other words, geometric mean is the nth root of the product of n values.
The formula for the geometric mean is given by:
GM = n√x1 x2 . . . xn
Solving for the geometric mean between 18 and 1.5 using the formula:
GM = n√x1 x2 . . . xn
where n = 2, x1 = 18, and x2 = 1.5
GM = √(18)(1.5)
GM = √27
GM = 3√3

Find the missing term of each arithmetic sequence.14,..., 28, ...........
Answers
The missing terms of the given arithmetic sequence AP are 14, 21, 28, 35.
What exactly is arithmetic progression?An arithmetic progression (AP) is a sequence with the same distinctions between each successive term.
Each term (apart from the first) in an arithmetic progression is derived by adding a specific number to the term before the first one.For the initial term 'a' of an AP as well as the common difference 'd,' the very next arithmetic progression equations are frequently used to solve different AP problems.An AP's most common difference 'd': d = a2 - a1 = a3 - a2 = a4 - a3 =...... = a - an-1. nth term of an AP: an = a + (n - 1) dThe sum of an AP's n terms is: Sn = n/2(2a+(n-1)d) = n/2(a + l), where l is the AP's final term.Now, in response to the question;
The arithmetic sequence.14,..., 28, ............
There are total 4 terms in the series.
Let the initial term is 'a₁' is given as 14.
Let the second term is 'a₂'.
Let the third term be 'a₃' which is given as 28.
Ans, the let the fourth term is represented as 'a₄'.
As, we know that in the AP, the difference of the two consecutive terms is equal and called as common difference.
Thus,
d = a₂ - a₁ ........(equation 1)
d = a₃ - a₂ .......(equation 2)
Thus, equating the two equation;
a₂ - a₁ = a₃ - a₂
Substituting the values;
a₂ - 14 = 28 - a₂
Simplifying the equation;
2a₂ = 28 + 14
2a₂ = 42
a₂ = 21.
Put the obtained value in equation 1 and find d.
d = a₂ - a₁
d = 21 - 14
d = 7
Now, estimate a₄.
a₄ = a₃ + d
a₄ = 28 + 7
a₄ = 35
Therefore, the complete arithmetic sequence is 14, 21, 28, 35.

Notice that:
a(1) = x
a(2) = x+y
a(3) = x+2y
We can find the common difference:
d = a(2) - a(1)

Recall the formula for the nth term of an arithmetic series:
a(n) = a(1) + (n - 1) . d
Substitute n = 10, a(1) = x, and d = y into the formula:
a(10) = x + (10 - 1)y
a(10) = x+9y

Austin runs a farm stand that sells raspberries and apples. Each pound of raspberries sells for $4 and each pound of apples sells for $1.50. Austin made $267.50 from selling a total of 95 pounds of raspberries and apples. Determine the number of pounds of raspberries sold and the number of pounds of apples sold.
Answers
Answer:
50 pounds of raspberries and 45 pounds of apples is sold
Solution:
Let "a" be the number of pounds of raspberries sold
Let "b" be the number of pounds of apples sold
Cost of each pound of raspberry = $ 4
Cost of each pound of apple = $ 1.50
Austin made $267.50 from selling a total of 95 pounds of raspberries and apples
Therefore,
a + b = 95
b = 95 - a ------ eqn 1
Austin made $267.50. Therefore,
number of pounds of raspberries sold x Cost of each pound of raspberry + number of pounds of apples sold x Cost of each pound of apple = 267.50
4a + 1.50b = 267.50 --------- eqn 2
Substitute eqn 2 in eqn 1
4a + 1.5(95 - a) = 267.50
4a + 142.5 - 1.5a = 267.50
2.5a = 125
a = 50
Substitute a = 50 in eqn 1
b = 95 - 50
b = 45
Thus 50 pounds of raspberries and 45 pounds of apples is sold
