Answer:
option D; 20/3 OR 6 2/3
Step-by-step explanation:
CONVERT THE HOURS INTO MINUTES;
3/4 × 60 = 45 mins
1hour = 60 mins
45 mins = 5 miles
60 mins = ??
cross multiply;
60 by 5 ÷ 45 to get 20/3.
Answer:
x = -1 + sqrt(78)/6
x = -1 - sqrt(78)/6
Step-by-step explanation:
Zeros are the x-values where the function is 0
f(x) = 0
6x² + 12x - 7 = 0
a = 6, b = 12, c = -7
Using Quadratic formula:
x = [-12 +- sqrt(12² - 4(6)(-7)]/2(6)
x = [-12 +- sqrt(312)]/12
x = [-12 + 2sqrt(78)]/12
x = -1 +- sqrt(78)/6
It would be a 3 out of 7 chance. Altogether there are 8 marbles. The problem states that 1 marble was taken out of the bag, now making the total amount of marbles 7. There are only 3 blue marbles. So the answer is 3/7.
