At 7 pm, the temperature was 66*F
Temp = 78 - 3x where x = number of hours
78 - 3(7-3)
78 - 12 = 66
Answer:
1) Distance=Speed*time
90=(x+1)*(x)+(2x+5)(x-1)
90=x^2+x+2x^2-2x+5x-5
3x^2+4x-95=0
2) 3x^2+4x-95=0. Using quadratic formula, we get
x=(-4±sqrt(16-4*3*(-95)<u>)</u>)/6, x=5 or - 19/5 but since x also represents time, it can't be negative.
3) Total time take she took for the journey is x+x-1=2x-1=2*5-1=9 hours
Answer:
339604.65 cubic feet
Step-by-step explanation:
We are given that 1 m is equal to 3.3 ft.
1 m = 3.3 ft
This means that if we find the volume of a cube of 1 m, we have its volume as:
In the same way, the volume of a cube of 3.3 ft (1 m) is:
This means that:
The Kuroshio sea tank has volume of 
. Its volume in cubic feet is therefore:
The volume of the tank is 339604.65 cubic feet.
