Answer:
400 passengers
Step-by-step explanation:
To solve the problem, a proportion would be best!
First, let's set up the left side of the proportion. Percents, when used in parts, are always part of 100%, making 100% a whole. We'll use both 10% and 100% as our first fraction, which should look something like this:
(with <em>p </em>standing for <em>part </em>and <em>w</em> standing for the <em>whole</em>)
Next, let's set up the right side of our proportion. We'll use the 40 for our part and x for our whole since that is the number we are solving for. The proportion should now look like this:
To solve, just cross multiply and divide! Multiply 40 by 100 to give you 4,000. Next, divide 4,000 by the remaining 10 to give you a final answer of 400. If 40 passengers on the flight are in first class, then there are 400 total passengers. Hope this helps!
The set of number can all be related to each other. They may all have more factors that are greater than 1.
Answer:
A) False
B) True
Step-by-step explanation:
For A) First let's do x/11 = 15. If you solved it by now, you will know that the answer is 0.7333333. So now you just do 11x15. Because the answer is different then the answer we got when doing the division, the answer for A is false
For B) B is definitely true because equation are any mathematical sentences that have an equation symbol. So it's like saying 8x3=24 and 6x4=24. These two equations end up with the same answer so B is true.
I hope this helped you find out the rest :)
Answer:
B.
Step-by-step explanation:
Given,
The time for set up the game = 
minutes,
Also, the time for each level of game is 
minutes,
If there are l levels of games,
Then the time taken in all levels of game = 
<em>
</em>
Hence, the total time ( in minutes ) = Set up time + time in all level
= 
We have 60-minute of free trial of the game,
So, the total time taken can not be exceed to 60 minutes,
= 
Which is the required inequality.
Option 'B' is correct.
