For the first one, since she earns $17 per hour, & she tutored for 12 hrs this month, all you have to do is multiply the amount she makes per hour by the hours she’s tutored for. so 12x17=$204 so she made $204 this month. For the second one, it’d be the same thing, just multiply 19.5 by 17, which would give you 331.5.
& For the second question, all you have to do is plug in the numbers to the equation above. so it’d be 540 gallons / 1 minute multiplied by 42 since that is the time the pool needs to be filled by. So, if you do that, you will get 22,680, so the answer will be : yes it will fill up on time.
Answer:
The final result is: n = 7/10 or n = 0.7.

Hello!
OK, so we need to find out 20 km = ? dam
What we know:
1 km = 100 dam
Now, lets multiply to get our answer:
20 × 100 = 2,000
This tells us that 20 km = 2,000 dam
Check:
2,000 ÷ 20 = 10
This tells us that we are CORRECT!
Answer: 20 km = 2,000 dam
Hope this helps! Good luck! (:
