A boat traveled 240 miles downstream, then 240 miles back upstream. The trip downstream took 20 hours. The trip back upstream to
kotykmax [81]

Answer:

it takes longer for the boat to get back because it's moving against the current. to see how fast the boat is moving, you divide the amount of miles traveled, by how long it took.

240/20 = 12

in still water the boat travels it's 12 miles per hour

240/ 60 = 4

against the current, the boat travels 4 miles per hour

if you need to find the speed of the current, you need to find the resistance that's going against the boat making it slow down. you do that by doing        12 - 4 = 8 miles per hour is the speed of the current.

Step-by-step explanation:

I hope this helps :)

Temperature can be measured in two different common units: degrees Celsius and degrees Fahrenheit. F(C) returns the temperature
KiRa [710]

Answer: The freezing temperature of water in degrees Fahrenheit is 32.

Step-by-step explanation:

Hi, to answer this question we have to replace the value of the variable "C" in the formula F(C), by the value given in Celsius that water freezes.

Mathematically speaking:

F(C) = 32 +1.8 C

F (0) = 32 +1.8 (0)

Solving for F (Fahrenheit), since any number multiplied by zero equals zero:

F = 32

The freezing temperature of water in degrees Fahrenheit is 32.

A turtle moves an an average speed of 12 inches/hour. How long does it take the turtle to travel 8 inches?
Korvikt [17]

Answer:

40 minutes

Step-by-step explanation:

We can solve this problem through finding the proportion...

Let the time taken to travel 8 inches at the speed be x

Hence, 12:60 :: 8:x

We must multiply the extremes and the nears..

Hence,

12x=60×8

x=60×8/12

x=40 minutes

Use demovires theorem to write the complex number in trigonometric form.
Anastasy [175]
\sqrt3+i=2\left(\dfrac{\sqrt3}2+\dfrac12i\right)

\begin{cases}\cos\dfrac\pi6=\dfrac{\sqrt3}2\\\\\sin\dfrac\pi6=\dfrac12\end{cases}

\implies\sqrt3+i=2e^{i\pi/6}

By DeMoivre's theorem,

(\sqrt3+i)^3=(2e^{i\pi/6})^3=8e^{i\pi/2}=8\left(\cos\dfrac\pi2+i\sin\dfrac\pi2\right)=8i
