Answer:
30
Step-by-step explanation:
Prime factorization of the numbers:
2 = 2 × 1
6 = 2 × 3
15 = 3 × 5
LCM(2, 6, 15)
= 2 × 3 × 5
= 30
Answer:
6/21
Step-by-step explanation:
1. First, check all the possible combinations for a pair of dice:
1-1
1-2 2-2
1-3 2-3 3-3
1-4 2-4 3-4 4-4
1-5 2-5 3-5 4-5 5-5
1-6 2-6 3-6 4-6 5-6 6-6
(Those are the numbers of the dice, separated by hyphons.)
2. Next, find out the products, since that is the info we need to go off of.
1
2 4
3 6 9
4 8 12 16
5 10 15 20 25
6 12 18 24 30 36
(those are all the products based on the same chart we saw above.)
3. Now, let's calculate the probability.
- Find the amount of prime numbers. (1, 2, 3, 5) Looks like there are four total.
- Find the amount of numbers that end in a five. (15, 25) There are two. I've skipped 5 because that is already on the list.
- Find the total amount of numbers. There are 21 in our case.
4. There are 6 numbers that will satisfy our needs. (prime or ending in 5)
There are 21 total.
6/21
If you need decimal form, there is a
0.2857 chance.
Hope this helped.
2x + 5y = -8 . . . (1)
-133x - 4y = -8 . . . (2)
(1) * 4 => 8x + 20y = -32 . . . (3)
(2) * -5 => -665x + 20y = 32 . . . (4)
(3) - (4) => 673x = 0
x = 0
From (1), 2(0) + 5y = -8
5y = -8
y = -8/5
We need more information. You don't give us enough information....? Provide an image please. Or at least name the polynomials...
Your answer is correct. Both base angles for that triangle are equal, meaning it is an isosceles triangle, and both the sides will have the same measure.
