Answer:
44.73 (C)
Step-by-step explanation:
Because 6.3 and 7.1 multiplyed together is 44.73 this answer is correct
Only 2 times!
36*2 = 72
86-72 = 14 which is less than 36
So only 2 times.
answer:
the mean for this is 27
step-by-step explanation:
all you have to do is add up all of the times
15, 18, 20, 22, 28, 37, 49
which would have given you
189
then you divide that number by how much times were written down
7 would be that number so
189/7 = 27
and this is what it is written in one equation
(15+18+20+22+28+37+49)/7
hope this helps you! :)
distance = speed × time
The distance traveled downwind is 14x. The speed upwind is 4 mph less than 14 mph, so is 10 mph. The distance traveled in x hours upwind is 10x. That distance is 6 miles short of the downwind distance, so we can write the equation ...
... 10x = 14x -6
... 0 = 4x -6 . . . . . subtract 10x
... 0 = x -1.5 . . . . . divide by 4
... 1.5 = x . . . . . . . the downwind travel time is 1.5 hours.
The remaining distance upwind is 6 miles, and it is covered at 10 mph, so will take ...
... (6 mi)/(10 mi/h) = 0.6 h
Then the total trip takes x hours downwind plus x hours upwind plus 6/10 hours to finish the upwind trip:
... 2x+0.6 = 2(1.5) +0.6 = 3.6 . . . hours
Answer:
5 + i
Step-by-step explanation:
The complex conjugates theorem states that if (a + ib) is a root of a polynomial equation then the complex conjugate (a - ib) will also be its root.
Now, in our case (5 - i) is a root of a polynomial.
The complex number (5 - i) has conjugate and it is (5 + i).
Therefore, (5 + i) will also be a root of the same polynomial. (Answer)
