Answer:
Statements (1),(2),(3),(4) are correct and statement (5) is not correct.
Step-by-step explanation:
To check the correct statement we go through the statements one by one and validate it from the given chart.
1). At time t=0 Melissa started from 8342 feet height and Corey started from 10004 feet so the statement is true that both started on different trails.
2). Melissa hiked up for 90 minutes and reached at 12921 feet and Corey hiked for 60 minutes to reach at 12921 feet so Melissa hiked for a longer period than Carey. Therefore this statement is true.
3). Third statement that Melissa and Corey crossed paths between 60 and 90 minutes is right. We can see that at when Melissa was going up from 11239 feet to 12921 feet Corey started descending from 12921 feet so they crossed their paths.
4). Corey started descending from t=60 but Melissa didn't so the statement is true.
5). As Melissa's time increased from 0 to 60 minutes her elevation increased consistently from 8342 feet to 11239 feet so the statement that her elevation decreased is wrong.
Answer:
52
Step-by-step explanation:
First find out how many beads cover 1 inch of the string which is 4 beads then multiply that number, 4, by the length of the string, 13. You should get 52.
X=18 (the answer is the second choice)
The speed was 4.1 MB/sec.
We first find the amount that was transferred within the first 125 seconds:
549-36.5=512.5
Now we divide this by 125, the number of seconds:
512.5/125 = 4.1
