A. 44
B. 58
C. 16
D. 32
Answer:
D. 32
Step-by-step explanation:
Median is the middle number
I.e. (34 + 30)/2
= 32
Answer:
D
Step-by-step explanation:
We need the formula for arc length (in radians) to solve this problem. The formula is:
Where
s is the arc length
r is the radius of the circle
is the intercepted angle
In this diagram, we can see that is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20
Also, if we look, we see that the radius is 5 cm, so r = 5
Now, we substitute into formula and find :
This is given in radians, so is 4 radians
D is the correct answer choice.
The length of each segment can be determine by subtract the length of three commercial.
The length of each segment is 5 minute 37.5 seconds.
Given:
Duration of TV program is 30 minute.
Duration of TV commercials is .
Calculate the total length of three commercials.
Subtract 7.5 from total 30 min TV program.
Now calculate the equal length of entertainment segments.
Thus, the length of each segment is 5 minute 37.5 seconds.

b) 2w (squared) -19w
d) 3w-19
The expression that represents the area of the classroom floor is 2w -19w
'A plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.'
According to the given sum,
Width = w
Length = 2w - 19
Area of a rectangle = length × width
= w × (2w - 19)
= 2w ( squared ) - 19w
Hence, we can conclude that the expression that represents the area of the classroom floor is 2w (squared) - 19w.

Answer:
B
Step-by-step explanation:
The area is calculated by length×width. In this case you don't know the length or width precisely so you say 2w (squared) because it's the width×width and you subtract 19 because then you actually have width×length.
