The speed of light is about 3x10^8 m/s what is the speed of light in kilometers per hour

Answers

Answer 1

Answer: $3*10^8 (m)/(s) \n\n 1m\to 10^(-3)km \n\n 1s\to 36*10^(-4) h \n\n\n 3*10^8* (10^(-3)km)/(36*10^(-4)s)= 10^8 * (10^(-3)*10^4km)/(12s)= \n\n =10^8* (10m)/(12s)= \n\n =10^8* 83*10^(-2) (m)/(s)=\n\n= \boxed{83*10^6 (m)/(s)}$

Answer 2

Answer: $3\cdot10^8 \ \frac{\big{m}}{\big{s}} =3\cdot10^5\cdot \frac{\big{10^3\ m\cdot 3600}}{\big{3600\ s}} =3\cdot10^5\cdot \frac{\big{3600\ km}}{\big{1\ hr}} =108\cdot10^7\ \frac{\big{km}}{\big{hr}}=\n\n=1.08\cdot10^9\ \frac{\big{km}}{\big{hr}}$

Someone help please.

Answers

Given:
Red = 1/3
Blue = 1/4
White = 5/12

1/3 + 1/4 + 5/12 ⇒ (1/3*4/4) + (1/4*3/3) + (5/12*1/1) ⇒ 4/12 + 3/12 + 5/12 = 12/12 = 1

Red: 4/12 = 0.33 ; Blue: 3/12 = 0.25 ; White: 5/12 = 0.42

Batch 1:
Red : 5.95 * 0.33 = 1.9635 ⇒ 2
Blue: 5.95 * 0.25 = 1.4875 ⇒ 1.5 or 1 1/2
White 2 1/2 given: 2.5 / 0.42 = 5.95 total

Batch 2:
Red: 9 * 0.33 = 2.97 ⇒ 3
Blue: 2 1/4 given: 2.25 / 0.25 = 9
White: 9 * 0.42 = 3.78 ⇒ 3 3/4

Batch 3;
Red: 3 1/3 ⇒ 10/3 ÷ 0.33 = 10.10
Blue: 10.10 * 0.25 = 2.525 ⇒ 2 1/2
White: 10.10 * 0.42 = 4.242 ⇒ 4 1/6

How many times greater is the value of the 6 in 560,984 than the value of the 6 in 85,560?

Answers

Each place value is 10 times higher than the one below it. The 6 in 560,984 is 3 place values ahead of the 6 in 85,560, and 10*10*10=1000, so it is 1000 times greater

After 1 month, the book club had 5 members. The number of club members doubled every month.How many members did the club have after 4 months?

[ ]

Answers

Alright, take it step by step...in month one, they had 5 members.
if the number doubles each month, then the second month they will have a total of ten members, right? in the third they will have twice the number before, or 2 times 10, 20. if you double 20, you have the number of people in the fourth month, giving you a grand total of 40.

Since you know that the number of club members doubled every month , you would multiply how much members in one month by 2
1 month= 5 members multiply by 2
2 month= 10 members multiply by 2
3 month = 20 members multiply by 2
4 month= 40 members

So, for each moth you multiply it by 2.
After 4 months there will be 40 members
