Answer:
68
Step-by-step explanation:
divide 1292 by 19 and you should get 68
Hey!
-----------------------------------------------
Steps To Solve:
67% = 0.67
108 x 0.67 = 72.36
100 - 67 = 33% of student's passed.
33% = 0.33
108 x 0.33 = 35.64
72.36 = 72 students got an F.
35.64 = 36 students got an A.
72 + 36 = 108
So our rounding is pretty accurate!

=108
Answer:
Step-by-step explanation:
First of all, we have to know that complex roots can happen only in pairs, because they are based on the square root of a negative number.
On the other hand, a third degree polynomial can only have 3 roots as solution, because the degree of the polynomial specifies how many roots would have.
So, if we only can have 3 roots, and complex roots can only happen in pairs, then f(x) would have zero complex roots or two complex roots only, those are the unique scenarios.
The speed of the boat in still water will be 30 miles per hour and the speed of the current will be 6 miles per hour.
The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
Let the speed of the boat in still water be x and the speed of water be y.
A boat traveled 504 miles downstream and back. The trip downstream took 14 hours. Then the equation will be
x + y = 504 / 14
x + y = 36 ...1
The trip back took 21 hours. Then the equation will be
x - y = 504 / 21
x - y = 24 ...2
Add equations 1 and 2, then the value of x will be
2x = 36 + 24
2x = 60
x = 30 miles per hour
Then the value of y will be
30 - y = 24
y = 6 miles per hour
The speed of the boat in still water will be 30 miles per hour and the speed of the current will be 6 miles per hour.

Answer:
The speed of the boat in still water is 30 mph, and the speed of the current is 6 mph.
Step-by-step explanation:
Let's say b is the speed of the boat in still water, and c is the speed of the current.
Distance = rate × time
Going downstream:
504 = (b + c) × 14
36 = b + c
Going upstream:
504 = (b − c) × 21
24 = b − c
Two equations, two variables. Solve with substitution or elimination. To use elimination, add the equations together.
60 = 2b
b = 30
Plug into any equation to find c.
36 = b + c
36 = 30 + c
c = 6
The speed of the boat in still water is 30 mph, and the speed of the current is 6 mph.
