A=B+C
2A=54000
A=27000 seats $30/seat=$810000
B+C=27000
24B+18C=571200
24B+18(27000-B)=571200
24B+486000-18B=571200
6B=85200
B=14200
C=12800
A=27000 seats, B=14200 seats, C=12800
Answer:
k = - 6.6667
Step-by-step explanation:
this is quite very simple to begin. I would encourage you take other practice questions similar to help with understanding it.
let us begin.
Given that ;
dT/dt = k ( Tm - T) where Tm is the temp of the medium
dT/dt = 5 degrees Celsius per minute when T = 70
so we have that, 5 = k ( 25 - 70)
remember to convert 5 degree celsius per minute to seconds
we have that;
5*60(sec) = k ( 25 - 70)
k = 5*60 / ( 25 - 70)
k = - 6.6667
note K is negative because we consider it for cooling process (temp decreasing).
cheers i hope this helps!!!
The answer is
2)40
3)y=3\2
Since 17 is the longest side, the "legs" of the triangle are 8 and 15 cm respectively...the area of a triangle is:
A=bh/2 where b is base length and h is height length,
A=8*15/2
A=60 cm^2
