A. A' (0,20), B' (16, 12), C'(8,4)
B. A'(0,10), B' (16,6), C'(8,2)
C. A'(0, 20), B'(8, 12). C'(4,4)
D. A'(0,5), B (4.3), C (2.1)

x = 23.78

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
