Step-by-step explanation:
The same triangle ~
10/m = 6/9
10 = 6m/9
(10)(9)/6 = m
15 = m
m = 15
Rose 40%
original=100%, now it is 140%
140% of original=now
140% of orignal=350
1.4 of original=350
divide both sides by 1.4
original=250
answer is C
other way
350/140=x/100
35/14=x/100
times both sides by 1400
3500=14x
divie both sides by 14
250=x
C is answer
Step-by-step explanation:
Answer. The probability of picking a blue marble from the blue urn is 2/6=1/3. The probability of picking a blue marble from the black urn is 11/15. The two events are independent so the probability of a blue marble from each urn is the product of the two separate probabilities=1/3×11/15=11/45.
