Answer:
Step-by-step explanation:
The lateral area that Rachel needs to cover is 21 inches squared. You find this by first finding the area of one triangular side. To do this, you must half the base of one side, so it makes 2, and multiply it by the height, which gets you to 7. Then, you must half this, as the formula for the area of a triangle states, and then multiply this by two as you at first found the area of only HALF the triangle. This should still get you to 7. Now, there are three lateral sides, not including the base, so you must multiply 7 by 3. This gets you 21.
Answer:
0.56 m/s
Step-by-step explanation:
The average speed of a body tells how fast is the body moving; it is calculated as:
v=\frac{d}{t}v=td
where
d is the distance covered
t is the time elapsed
In this problem, we don't know the distance covered by Ben. Therefore, we will assume that it is 1 km:
d = 1 km = 1000 m
The time elapsed to cover this distance is:
t=30 min \cdot 60 =1800 st=30min⋅60=1800s
Therefore, Ben's average speed is:
v=\frac{1000}{1800}=0.56 m/sv=18001000=0.56m/s
Hope this helps
