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:

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:

Therefore, Ben's average speed is:

Answer:
(5/6)x²
Step-by-step explanation:
The area of a triangle is given by the formula
A = (1/2)bh
Here, the base is 5/3x, and the height is x. So, the area is ...
A = (1/2)(5/3x)(x) = (5/6)x²
Answer:
arc NO has measure 48
Step-by-step explanation:
We assume all measures are in consistent units (degrees or something similar). The two inscribed angles intercept the same arc, so are congruent:
9x -3 = 4x +12
5x = 15 . . . . . . . add 3-4x
x = 3 . . . . . . . . . divide by 5
The measure of the inscribed angle is then ...
4x +12 = 4(3) +12 = 24
That is half the measure of the arc, so the measure of arc NO is ...
arc NO = 2·24 = 48
U see the box in the triangle is 90 so use it solve it
<h3>Why isn’t a good idea to study in bed?</h3>
Answer: Working or doing homework in bed will reduce one's focus because most people tend to associate their beds with comfort and sleep. Doing such activities in bed can lead to a deviation of the brain to become more lazy and possibly fall asleep.
