Answer:
Year 1 and 2
36%
Step-by-step explanation:
Given the data :
Year ______1 ___ 2 ____ 3 ___ 4
Students __ 14 __ 19 ___ 25 __ 33
Greatest growth is observed between year 1 and 2
Growth percent :
(year 2 - year 1) / year 1 * 100%
(19 - 14) / 14 * 100%
5 / 14 * 100%
0.3571 * 100%
= 35. 71%
= 36%
The growth percent between year 1 and 2 is greater than between the other years
Year 2 and 3 = (6/19) * 100% = 31.57%
Year 3 and 4 = (8/25) * 100% = 32%
Answer:
B
Step-by-step explanation:
Answer:
- complement: 32.8°
- supplement: 122.8°
Step-by-step explanation:
The sum of an angle A and its complement C is 90°:
A + C = 90°
C = 90° -A . . . . . subtract A from both sides.
That is, the complement of an angle is found by subtracting the angle from 90°.
__
The sum of an angle and its supplement is 180°. This means the supplement of an angle is found by subtracting the angle from 180°. You may notice the supplement is 90° more than the complement.
A + S = 180°
S = 180° -A = 90° +(90° -A)
__
For the given angle, the complement is ...
C = 90° -57.2° = 32.8°
And the supplement is ...
S = 180° -57.2° = 122.8°
_____
<em>Additional comment</em>
We generally like angle measures to be positive (as with all measures in geometry). Hence, we might say that the complement of an angle greater than 90° does not exist. YMMV
