Answer:

Step-by-step explanation:

Assuming the ramp is against a wall or building at a 90 degree angle, then the 3 angles formed by the triangle within the ramp and wall are 9 +90 + x = 180 so 99 + x = 180 so x=81

The probability that it will snow on Sunday is 3/5. The probability that it will snow on both Sunday and Monday is 3/10. What is

skad [1K]

Answer:

1/2

Step-by-step explanation:

Probability of snowing on both Sunday and Monday= probability that it will snow on Sunday × probability that it will snow on Monday.

(and usually means multiply the probabilities while or implies addition of the probabilities).

Let probability of snowing on Monday be P

Hence 3/10=3/5× P

Hence P=(3/10) divided by (3/5) = 1/2

Can you factories them

For each part A through D below, the idea is to find the common factor between the terms, which you'll then use the distributive property to pull out.

==================================

Part A

3x + 18 = 3(x+6)

Note how we pulled out a 3. If we distribute it back in, we end up with 3x+18 again. The other problems are done in a similar fashion

==================================

Part B

2x - 14 = 2(x - 7)

==================================

Part C

6x + 4 = 2(3x + 2)

==================================

Part D

9x - 15 = 3(3x - 5)
