It is so easy.

It's a long time.

The last answer should just be in "Meters" not m/s.

You didn't state the distance to the Andromeda galaxy!?. I just happen to know that it's about 2.5 million lightyears away. But your car is travelling at ONLY 30,000,000m/s or 1.08×10^8 km/h.

Since the speed of light is 10 times faster than your car, it will take it about 10 longer to get to Andromeda, or about 25,000,0000 light years to get there!(A light year is about 3 X 10^8 X 3,600 X 24 X 365=9.4608 X 10^15m/s)

The answer is 64.

The answer is:

i √46. This is called a "Complex Number"

ALL electromagnetic waves(including radio waves) travel at the speed of light, which is about 3 X 10^8 meters per second.

Wavelength=Speed of light / Frequecy,

Wavelength=3 X10^8/500,000=600 meters

P.S. Your first answer should be 300,000,000m/s. You got wrong by 10.

If this is

(3/4) (1 + 1/3)  + (1 + 1/3)  =

(3/4)(4/3) + (1 + 1/3 ) =

1 +  (1 + 1/3)  =  

2 + 1/3 =

7/3

If this is 

(4/3) [ (1 + 1/3) + (1 + 1/3)] =

(4/3) [ 4/3 + 4/3 ] =

(4/3) [ 8/3]  =

32/9

3/4 of 1 1/3 + 1 1/3

The result is=7/3

99 factors as 9 x 11

117 factors as 9 x 13

Thus, we could use 9 trays, each holding  11 hot dogs and 13 buns

This type of problem is solved using graphing. The other way that it can be solved is called "Interpolation", which is an advanced way of solving these kinds of problems. You learn this in late High School or at University math courses.

Guest...it would be difficult to solve this by using Algebra........we can use a Calculus technique, but it's a little difficult........

Here's a graphical solution :   https://www.desmos.com/calculator/xh6bf1qslg

The solution is that p = about 1.395

Thannk you 

but I want to know the process of solving this types of equation .

Cos=Adjacent side/Hypotenuse

how to solve equation 2^p-3^p=-2

The answer is p=1.39495.......etc.

(0.75-x)/x={(2%-0.25%)/1+2%)

x=60/83

The faster rummer completes 1/4 of a lap in one minute when the slower runner completes 1/19  of a lap in one minute

So  

(1/4 - 1/19)T = 1

(15/76)T = 1    multiply both sides by  76/15

T = 76/15 min  = about 5.066 min

Proof

In 5.066min the faster runner runs  5.066(1/4)   = 1.266 laps

In 5.066min the slower runner runs 5.066(1/19)  = .266 laps

Thus....the first runner runs one more lap in 5.066 min

83 / 52= 1 31/58

The number π is a mathematical constant, the ratio of a circle's circumference to its diameter, commonly approximated as 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as "pi".

147 / (8 + 1/6)   = 

147 / (49/6)  =

(147) x (6/49)  =

147/49  x 6  =

3  x 6 =    18 mi/gal

The car got 147 /  (49/6)= 147 X (6/49)=882/49=18 gallons per mile.
