Answer: 49.09 cm2
Step-by-step explanation:
Hi, to answer this question we have to apply the next formulas:
Circumference of a circle = π x diameter = 3.14159x 3 1/8 = 9.81746 in
The circumference of the can is equal to the length of the rectangular label:
Surface area (S)= circumference(length) x height
Replacing with the values given:
S = 9.81746 x 5 = 49.09 cm2
Feel free to ask for more if needed or if you did not understand something.

Answer is A
Answer:
450 people paid the discounted fare and 750 people paid the regular fare.
Step-by-step explanation:
let r be regular fares paid and d be discounted fares paid
Total fares = 0.8r + 0.4d = 780
Since 1200 people paid the fares,
r + d = 1200 = Total people
Rearrange this formula:
r = 1200 - d
Substitute r into Total Fares formula
Total fares = 0.8r + 0.4d
780 = 0.8(1200-d) + 0.4d
780 = 960 - 0.8d + 0.4d
780 = 960 - 0.4d
0.4d = 180
d = 450
Sub d=450 into Total people formula
r + d = 1200 = Total people
r + 450 = 1200
r = 1200-450
r = 750
450 people paid the discounted fare and 750 people paid the regular fare.
She will need a minimum of 38 hours, at 38 hours she will make 456, plus the 300 she already has, so that in total is 756.
