To find the least common denominator, or lcd, you have to find the least common multiple, or lcm. To do that you find the multiples of each number until they equal each other. I set up a chart like this,
6 -
8 -
and then I start listing multiples so,
6 - 6, 12, 18, 24,
8 - 8, 16, 24,
I stop after I find a number they are both equal to. So to get to that number I would multiply 8 by 3, and 6 by 4. This gives me 24 as the lcd. If you need the lcd to add the fractions together, then whatever you did to the bottom do to the top. So 5/6 would become 20/24 and 3/8 would become 9/24.
Answer: 24

Answer:
The question continues ; I take it is defined as a set of five white and one red number how many possible different Powerball tickets can be purchased how many possible different winning Powerball tickets are there
Step-by-step explanation:
he concept of combinatorics ( combination and permutation) is applied her
nPr = n!/(n-r)!
nCr = n!/(n-r)!r!
Hence number of possible different powerball tickets = number of ways of selection
= selecting 5 white ball from a total of 69 and selecting a red ball from a total of 26
= 69C5 x 26C1
using the formula above for combination
= 69!/(69-5)!5! x 26!/(26-1)!1!
= 292, 201, 338 ways
Answer:
-1458
Step-by-step explanation:
Let's find the rule of the sequence. It seems that each term is -3 times the previous term.
Let's continue the sequence.
486, -1458
-1458 is the 7th term
Answer:
Adult ticket = 80
Children ticket = 120
Step-by-step explanation:
Given that :
Cost of student ticket = $8
Cost of adult ticket = $10
Number of tickets sold = 200
Total amount collected = $1760
Let number of adult ticket sold = a ; children ticket = b
a + b = 200 _-_(1)
10a + 8b = 1760 ___(2)
a = 200 - b
10(200 - b) + 8b =. 1760
2000 - 10b + 8b = 1760
- 2b = 1760 - 2000
-2b = -240
b = 120
a = 200 - b
a = 200 - 120
a = 80
