1 Chicken have = 2 legs
1 Cow have = 4 legs
No of cows = x
No of chickens = y
Total no of legs = 4x + 2y = 210.............(1)
Total No of heads = x + y = 84................(2)
x = 84 - y....( from (2) )
Substituting the above equation in (1)
4 ( 84 - y) + 2y = 210
336 - 4y + 2y = 210
336 - 2y = 210
-2y = -126
= y = 63
No of cows = 84-63 = 21
∴ <u><em>Total no of cows = 21</em></u>
<u><em>Total no of chickens = 63</em></u>
So 2/3 of 36 is 24. So 24 that were filled and 2/3 of 40 is 80/3 which equals 26 2/3 to drain it. And then to fill the pool would be 36 hours. What's so hard...
Answer:
Independent Events
Step-by-step explanation:
Two events are mutually exclusive or disjoint if they cannot both occur at the same time.
Two events are independent if the probability of occurrence of one does not affect the probability of occurrence of the other.
The complement of any event B is the event [not B], i.e. the event that B does not occur.
Australia plays Argentina for the championship in the Rugby World Cup.
At the same time, Ukraine plays Russia for the World Team Chess Championship.
A = event that Argentina wins their rugby match.
B = the event that Ukraine wins their chess match.
The two events A and B are Independent as the outcome of one does not affect the outcome of the other

i got it correct on edge
The answer to this question is 24/99. 0.24 with 24 repeating in fractional form is 24/99. You put a 9 in the denominator for every repeating digit.
