Answer:
150 degrees
Step-by-step explanation:
- Let the supplement = x
- So the angle you want is 5x
- Then [x + 5x] = 180 because they are supplementary.
- Solving. 6x = 180. Then x = 30.
- So the angle is 5x = 5×30 = 150 degrees
Answer:
they got -21 when they were supposted to get +21
and they also got +6x when they were supposted to get -6x
Step-by-step explanation:
that's because -3 and 2x are multiplied together and when you are multiplying negative and positive number you need to get negative result.
when you are multiplying negative with negative number, you will get positive number.
C is your answer
4 x 2 is pretty much 4 groups of 2
hope this helps
Answer:
Step-by-step explanation:
P(A) = 0.70
P(B) = 0.20
P(A n B) = P(A) x P(B)
P(A n B) = 0.70 x 0.20
P(A n B) = 0.14
"Or" means that they are mutually exclusive, which it does not specifically mention, therefore B and C are out.
This creates a cone! :) the formula for volume of it is 1/3 pi R^2 (h) just in case!
