How do I find a least common denominator? ​

Mathematics

Answer:

Below.

Step-by-step explanation:

You can find this by first finding the prime factors of the numbers.

For example, find the LCD of 12 and 16:

12 = 2 * 2 * 3

16 = 2 * 2 * 2 * 2

There are 2 pairs of 2's in the list so only 2 of these four are included in the calculation. All other factors are included.

The LCD is:

2 * 2 * 2 * 2 * 3

= 16*3

= 48.

Find the LCD of  3 and 6

6 = 2 * 3

3 = 3

- so only one of the 3's is included:

LCD = 2*3 = 6.

Answer:

to find the least common denominator list out the multiples of both denominator until you find the smallest multiple that is shared by both

4: 4,8,12,16,20,24,28,32,

7:14,21,28,35,

because 28 is the first shared multiple of 4 and 7,it most be the least common denominator for these two fractions.

Step-by-step explanation:

the area of a rectangular decks is 680 square feet. the decks width is 17 feet. what is its perimeter ?
Ket [755]
The perimeter is 114 square feet. To solve this, first you divide 680 by 17, which equals 40. So the length is 40. The formula for perimeter is 2L+2W. This means you take the length and multiply it by 2, and do the same for the width, then add them together. So the equation would be:
2(40)+2(17)=Perimeter
80+34=Perimeter 
The final answer is 114 square feet.

Abraham is writing a recursive function for the geometric sequence:
zaharov [31]

Answer:

a1 = 24

an = an-1 × 1/2, n >1

Step-by-step explanation:

a geometric sequence is a sequence where we multiply every previous term by a certain factor to create the next term.

so, we multiply 24 by something to get 12.

and then 12 by the same something to get 6.

and then 6 by the and something to get 3.

do you see the pattern ? hmmm ?

right, we always divide by 2 (or multiply by 1/2).

the starting value a1 = 24

so,

an = an-1 × 1/2, n>1

or

an = a1 \times  {(1 \div 2)}^{n - 1}

n>1

In the figure shown, what is the measure of angle x?
mojhsa [17]
Angles in a triangle must add up to 180, so the missing angle inside the triangle is 180 - (70 + 40), which is 70.

Angles on a straight line (i.e. the line BD) must add up to 180, and because we know part of that angle is 70, x must be 180 - 70, which is 110.

Hence, x is 110 degrees.
