They're all used for differentiating types of measurement in mathematics and science.

9 to 11 = 9:11</span>
<span />If u times 2 you will get 18:22 which is equivalent to 9:11
<span>Next u could do 18:22 times 2 to get another equivalent answer to 9:11 </span>
<span /><span>You could just continue this to get more equivalent answer to 9:11</span>

2 times 10^4 means 2 with 4 zeroes after it or 20000
4 times 10^6=4 with 6 zeros after it or 400000
compare
20000 and 4000000
we can see that 4000000 is 200 times of 20000
therefor the answer is C
we can also do
(4 times 10^6)/(2 times 10^4)=4/2 times (10^6)/(10^4)=2 times 10^2=200
answer is C
Answer: 360ft
Explanation:
x = 18/1/20
x = 18 x 20
x = 360ft
Answer:

Step-by-step explanation:
Given,
Art electives = 3,
History electives = 4,
Computer electives = 5,
Total number of electives = 3 + 4 + 5 = 12,
Since, if a student chooses an art elective and a history elective,
So, the total combination of choosing an art elective and a history elective = 
Also, the total combination of choosing any 2 subjects out of 12 subjects = 
Hence, the probability that a student chooses an art elective and a history elective = 

Which is the required expression.
