Step-by-step explanation:
1.) Apoorva got 105 points removed. If 15 points are removed for each missed target, they want you to find out how many times 15 points were removed/ how many times 15 goes into 105. 15 goes into 105 7 times, so, your answer is that she missed 7 targets.
2.) The length of the island is changing by the same amount each year. We know that it changes -255 cm every 15 years, but, since we're trying to find out how much it changes per year, we have to change the time amount. Since we have to divide 15 years by 15 to get it to 1 year, we will also have to divide the distance by 15 to find the yearly change. When you do this, you find out that the island changes -17 cm per year.
Sorry if this doesn't make sense, but, if it does, please mark it as the brainliest answer!!!
