This is a question of proportionality. However, it is not direct proportionality as it is expected that as the number of tractors increases, the work is finished faster as opposed to fewer number of tractors. This is referred to as inverse proportionality.
Therefore;
6 tractors ----- 10 days
18 tractors --- x days
Then,
x = (6*10)/18 = 10/3 days = 3 days, and 8 hours.
This means that 18 tractors will take 3 days and 8 hours to collect the same harvest.
Answer:
P(A|B) = 8/12 = 66.67%
Step-by-step explanation:
From 1 to 24, the number of odd numbers is 12, so event B has 12 possible values.
Among these 12 odd numbers in B, the ones that are prime are:
3, 5, 7, 11, 13, 17, 19, 23 (total of 8 numbers)
so given event B, the event A has 8 possible values inside the sample space of B.
So the probability of A given B, that is, P(A|B), is:
P(A|B) = 8/12 = 66.67%
The angle of elevation always stands on ground level. So, angle 8 is the answer.
Answer:
d 
-39
Step-by-step explanation:
d/13-3
multiply both sides by 13
d 
13(-3)
d -39
