Answer:
Step-by-step explanation:
(1/2)/3 = x/4
1/6=x/4
x=4/6 = 2/3
30.007
300/10=30
7/1000=.007
30+.007=30.007
Answer:
A.) in 6 hours Rovan can make 288 tarts
B. at this rate it'll take Rovan about 2 and a half hours to make 120 tarts
Step-by-step explanation:
so if Rovan can make 48 tarts an 1 hour take 48 and multiply it by the hours to find out how many tarts he can make
48 x 1 =48
48 x 2 =96
48 x 3 =144 .....
48 x 6 =288

Total number of marbles in the bag =20
Number of blue marbles =4
Now we just want two blue marbles out of four.
Probability of taking out first marble which is blue =4/20
Now after we took out one blue marble , number of blue marbles left are 3.
Probability of taking out second marble which is blue =3/20
Total probability = 4/20 *3/20 = 12/400
So probability of taking out two blue marbles is 0.03 or 12/400.
