Answer:
120 ways
Step-by-step explanation:
This can be solved through analytical combination.
First, select the president; this implies selecting one person out of five people, which is in 5 ways.
Secondly, select the vice president, this implies selecting one person out of four people, since one position has been taken by the president already leaving only four people which is in 4 ways
Thirdly, select the secretary, this implies selecting one person out of three remaining people, which is in 3 ways
Lastly, select the treasurer, this implies selecting one person out of two remaining people, which is in 2 ways
Therefore, ways by which a president, vice president, secretary, and treasurer can be elected is
5 x 4 x 3 x 2 = 120 ways
Average speed for the entire journey was 62 miles per hour.
Total time of the journey was 5 hours.
In first 2 hours, her average speed was 60 miles per hour. This means, she covered 120 miles in first two hours, as
Distance = Speed x Time
The total distance of the entire journey was:
Total Distance = 62 x 5 =310 miles
Out of these 310 miles, she covered 120 miles in first two hours. So this means she covered (310 - 120) miles in next 3 hours.
Thus she covered 190 miles in 3 hours. So her average speed will be 190/3 miles per hour which is equal to 63.33 miles per hour.
So, the average speed for last 3 hours of the trip was 63.33 miles per hour
The surface area of a solid object is a measure of the total area that the surface of the object occupies
Cube SA=6s^2 s =length of the side
Prism SA= 2B + ph B = area of the base. P = perimeter of the base. H =height
Answer: 91 degrees
Step-by-step explanation:
you see 89, angle 2 is just a little bit more bigger than 89 so yeah
