The veryy basic rule of annual compounding:

F = P (1 + r )^n

P: original amount invested = $11,600,
r: interest rate = 10%,
F: Future value of P = $30,052 (don't get misled with terms,...

q = 113 joules (energy required to evaporate all liquid water in 1m3 of fog)

* refer to your other post on how we calculated this energy.

if it is given that sun can supply Q =40 J s-1, then...

first thing is to calculate how much liquid water is there in 1m3 of fog. Fog has 0.05 g/m3 liquid water density => in 1m3 of fog there is 0.05 g of water.

and q = m Hv,

43 inches of circumference and 1 feet length.

circumference: 2*pi*r = 43 inches ---> r = 6.847 inches

good luck again.

1 revolution = 2 pi radians
and pi = 3.14
so 4 revolutions = 4 * 2 * 3.14 radians
dont have a calculator, rest is very obvious.

first step is to determine which side to simplify, first obvious thing to do is to relate to this: (a^4 - b^4) = (a^2 - b^2) * (a^2 + b^2),
so we have to...

simply use the formula: cos(A+B) = cos(A)cos(B) - sin(A)sin(B)

in your question let A = 5x and B = -2x (because 5x - 2x = 3x)

so cos (5x+ (-2x)) = cos(5x)cos(-2x) - sin(5x)sin(-2x)
where,...

Final amount = original amount + interest
-F: final value
-P: present value
-r: interest rate (per year)
-t: time in years
F = P * (1 + r * t )
F = 18800 (1+0.08(3)) = $ 23,312.

The given is not really clear!

What I understood..
(a+4) + (b-4) + (c*4) + (d/4) = 60
a+b+4*c+0.25*d = 60
then you have many solutions for a, b, c, and d.
one can be:
a = 10
b= 12
c = 4

yeah sorry forgot the time variable!

(m/t) = ρ*V*A... right side kg/sec (kg/m^3 * m/sec * m^2 = kg/sec)

m = ρ*V*A

V = m / ( ρ* A )
V = 500 / (1.3 * 30 ) = 12.8205 m/sec

you are confused if the answer is 4*10 or 10/4

The statement clearly says: Blank is 4 times the 10 = 4*10 = 40

The other way around would be: 10 is 4 times as many as blank (in this case...

There is one solution.

For the first case: t1 = 1/v.. hr
For the second case (speed increase): t2 = 1/(v+8.4)... hr

The time difference is 14 sec = 14/3600 hr
