Answer:
a = 51
b = 51 (??not so sure)
c = 20 cents
Step-by-step explanation:
a) 25 x 408 = 10200
10200 ÷ 200 = 51 square ft is one one roll.
b) the surface area of an average gift is 51 sq ft (?)
c) 40 ÷ 200 = 0.2
each roll costs $40 dollars. each roll can wrap 200 gifts so 40 ÷ 200 = $0.20/ 20 cents
I think the answer is A. 7 5/6
18 points scored for a pair was 40 % of the final score
then final score is 100%
therefore if 40 % accounts for 18 points
100 % = 18 / 40% *100%
= 45 points is the final score
if we back calculate = 18 /45 *100 = 40%
Therefore the final score is 45 points
The first answer we see is true the other is based on personal experience
To solve this problem, you need to use the Exterior Angle (Out) equation which for this problem would be

. After correctly solving the problem with this equation, you will figure out that the answer is 79.
mHJ= 79°
Hope this helped :)
