390-35=355
355-10w
355/10=35.5
355-10(35.5)
35 and a 1/2 weeks
36 weeks to have the full amount needed
Chance of a 2: 1/10. Chance of a 3: 1/10. These are disjoint events (they can’t happen at the same time) but we need the probability that either can happen. So 1/10+1/10=2/10=1/5.
This intuitively makes sense since there are 2 numbers out 10

Answer:
Letter A is 12*12*12*12*12*12*12*12*12*12*12*12*12*12*12=180
Letter B is y
,
x
=
2
Step-by-step explanation:
Answer:
S = 1/2 . x^2 + 11/2 . x + 15
Step-by-step explanation:
- Let S = the area of the shaded region
- From the figure we see that S = 1/2 the area of the rectangle
- The area of the rectangle is (x+5)(x+6) = x^2 + 11x + 30
--> S = 1/2 (x^2 + 11x + 30)
--> S = 1/2 . x^2 + 11/2 . x + 15
