Answer:
BC = 5.87
Step-by-step explanation:
Reference angle = 50°
Side Opposite to reference angle = 7
Adjacent side = BC = ?
Apply trigonometric function, TOA, thus:
Tan 50 = Opp/Adj
Tan 50 = 7/BC
BC × Tan 50 = 7
BC = 7/Tan 50
BC = 5.87369742 ≈ 5.87 (nearest hundredth)
You replace the p in the given expression by -2 and the m by 3 and simplify
So its (-2)^ / 4 - 3
= 4/4 - 3
= 1 - 3 (note the division 4/4 is done first according to the order of operations rule)
= -2 answer
Answer: d
Step-by-step explanation:
The probability of not being purple is the probability of the three other colors. Suppose the number of purple marbles is x. Then we have 20+30+40+x = 90 + x marbles. Then the probability of not being purple is 90/(90+x). If this fraction can have a lowest term for some value of x, then the numerator of this lowest term must be a factor of 90.
Checking through the options, only option D has a non-factor of 90 as its numerator.
1/10 of 30000 is 3000 because 30000 divided by 10 is 3000.
