Answer:
8.5
Step-by-step explanation:
Given the expression 12.75/1.5. The technique in solving the division expression is as shown
First we can write the decimals as fraction as shown;
12.75 = 1275/100
1.5 = 15/10
12.75/1.5 = (1275/100)÷(15/10)
12.75/1.5 = 1275/100×10/15
12.75/1.5 = 1275/10 × 1/15
12.75/1.5 = 1275/150
12.75/1.5 = 8.5
Hence the result of the division is 8.5

Answer:
150,000*3^t for 6 hour increments (t=1 is 6 hours t=2 is 12)
150,000*3^(t/6) for hourly increments, each t is 1 hour.
Step-by-step explanation:
Well super simply you could do 150,000*3^t where t is measured in 6 hour intervals. so t=1 is 6 hours, and to get 1 hour you would need to do t=1/6
If you want t to be an increase of every hour you would just need to adjust, like I showed before 1/6 gets one hour so 150,000*3^(t/6) would be the model where every t increases by 1 hour.
Answer: 13
Althoug each round trip takes 9 minutes and can carry 5 people on the boat, you can not just divide the 20 minutes time by 9 and multiply by 5 to find the number of people that are saved without getting wet.
First trip:
5 people take the boat to the island but only 4 can stay, because one has to return with the boat to the ship to rescue other 4 people.
So, when 9 minutes have passed, 4 people are safe on the island and the boat is again by the ship.
Second trip:
In the second trip, other 4 people are rescued,along with "sailor" who returned in the boat to rescue them.
When it has passed 18 minutes, the boat is next to the ship agin to carry other 4 people before the boat sinks.
This is the last trip before the boat sinks. So, the total number of passengers rescued is 4 + 4 + 5 = 13
