Answer:
100
Step-by-step explanation:
Round 9304 to 9300. 9300/93 is just 100 since 100 * 93 = 9300 (this is something easily recognizable).
Answer:
Average speed =
miles per hour
Step-by-step explanation:
Formula to calculate the average speed of an object is,
Average speed = 
If I travel with the speed of x mph for t hours,
Total distance covered = Speed × Time
=
=
miles
Similarly, if I travel with the speed y mph for t hours,
Total distance covered =
miles
Total distance covered by me =
miles
Total time taken to cover this distance = 
=
hours
Therefore, expression for the average speed will be,
Average speed = 
= 
=
miles per hour
Step-by-step explanation:
1) if (0;0) if point A, (1;2) is point B; (-1;-2) is C, (2;1) is D, then
2) the vector AB is (1;2); vector AC is (-1;-2) and vector AD is (2;1), then
3) the length of AB, AC and AD are:



4) if the lengths above are equal, then it means that (0, 0) is equidistant from (1, 2), (-1, -2) and (2, 1).
