The speed of light is 3*10^5 kilometers per second. if a light-year is the distance light travels in one earth year, how many kilometers are in one light-year? (one earth year=365.25)

9.46 X 10^12 kilometers

Step-by-step explanation:

We will solve this problem by applying s=vt formula.

Here, s= distance

v= 3X10^5 km/s

t= 365.25 days = 365.25 X 3600 X 24 = 31557600 seconds

Now, s=  3X10^5 km/s X 31557600 seconds =  9.46 X 10^12 kilometers

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
