Answer:
184320 Cubic Cenimeters
Step-by-step explanation:
Answer:
3mph
Step-by-step explanation:
Boat speed x
current speed 2
against current x-2 mph
with current x+ 2 mph
Distance= 5 miles
Time against + time with = 6 hours
5 /( x + 2 ) + 5 /(x - 2 ) = 6
LCD = (x - 2 ) ( x + 2 )
5 *( x - 2 ) + 5 (x + 2 ) = 6
5 x - 10 + 5 x + 10 = 6 ( x ^2 - 4 )
10 x = 6 x ^2 - 24
6 x ^2 - -10 x - 24
Find the roots of the equation by quadratic formula
a= 6 , b= -10 , c= -24
b^2-4ac= 100 + 576
b^2-4ac=676
x1=(10+26)/12
x1=3
x2=(10-26)/12
x2= -1.33
Ignore negative value
Speed of boat is 3 mph
The answer would be C) 4,000 per year because if you add 4 to 8 its 12 add 4 to 12 its 16 then 4 to 16 is 20 then 4 to 20 equals 24
