the diagonal squared = base squared + altitude squared.
5280 - 10 = 5270 ft, traveled by the 2nd place runner
5280 - 23 = 5257 ft, traveled by the 3rd place runner
Use a ratio equation5280/5270 = x/5257
Cross multiply:
5270x = 5280 * 5257x
= 27756960/5270x
= 5266.975 traveled by the 3rd place runner when the 2nd place runner crosses the finish line.
5280 - 5266.975
= 13.025 ft is the distance the 2nd place runner beats the 3rd place runner.
This makes sense because they were 13 ft apart when the winner crossed the line, the 3rd place runner is 13 ft behind the 2nd runner because he runs slower.
Answer:
i THINK YOU SHOULD SPILT IT HALF
Step-by-step explanation:
first u need the value of any one variable
3√10 + 7√15 - 6√10 - 4√15
3√10 - 6√10 + 7√15 - 4√15
-3√10 + 3√15
The answer is B.
