Answer:
100 not so good seats
50 good seats
Step-by-step explanation:
Let x represent good seats and y represent not so good seats
[i] 3x + 2y = 350
[ii] x+y = 150
[iii] y = 150 - x
substitute this to equation [i]
3x + 2y = .350
3x + 2 (150-x ) = 350
3x + 300 - 2x = 350
3x-2x = 350 - 300
x = 50 good seats
now substitute what you got to equation [iii]
y = 150 - 50 = 100 not so good seats
when we check the answer by using equation [i] we find that it is correct:
3x + 2y = 350
3(50) + 2(100) = 350
150 + 200 = 350
350 = 350
Add all the displacement vectors together, then find the magnitude of this vector sum.
Summing these vectors gives the resultant displacement
and we have
so the plane ends up about 81.9 km away from its starting position.
The answer is C because it’s the one that makes most sense
Answer:
19.635
Step-by-step explanation:
A=pie Radius^2
The sum and product of two functions 
and 
, i.e. 
and 
respectively, are simply defined as the sum and product of the expressions that define each function.
So, as for exercise 13, we have
Similarly, as for exercise 20, we have
