Answer:
The 80th term would be 647
Step-by-step explanation:
In order to find the 80th term, you need to find the rule for the sequence. You'll notice that the numbers are going up by 8. Since there is no 0th term, the first term would be 8 more than the base.
15 - 8 = 7
Therefore the base is 7. As a result, you can model the sequence as:
An = 8n + 7
In which n is the number in the sequence. Now knowing this, we can plug in 80 and get the answer.
An = 8n + 7
An = 8(80) + 7
An = 640 + 7
An = 647
Answer: 1h and 25min
To find how long you can drive in a minute we do 48 divided by 32 = 1.5. So it takes 1 min to drive 1.5km
Then we 146 divided by 1.5 = 97 and a third to find out how long it takes to drive 146km.
Then we convert it to hours to get 1h and 57min.
Then we - 32 because we already drove 32min. 1h and 57min - 32 = 1h and 25min

Answer:
4 : 7
Step-by-step explanation:
The area ratio is the square of the side length ratio. So, the side length ratio is the square root of the area ratio.
side length ratio = √16 : √49 = 4 : 7
