Complete question :
Sam knows that his MP3 player has 40% of its battery life left and that the battery
charges by an additional 12 percentage points every 15 minutes. What percent of
the mp3's battery will be charged when Sam and his family leave? If mp3 was plugged in an hour before his family plan to leave.
Answer:
88%
Step-by-step explanation:
Time before leaving = 1hour
Current percentage = 40%
Charge rate = 12% every 15 minutes
Therefore,
Charge rate per minute :
12% / 15 = 0.8% per minute
Charge recieved after one hour (60 minutes) :
0.8% * 60
= 48%
Therefore, total charge after just before leaving is:
Current percentage + percentage received
40% + 48%
= 88%
Answer:
Where is M??
Step-by-step explanation:
Step-by-step explanation:
7. ∆ABC = ∆ILH by SSS
as, AB = IL , BC = LH , CA = HI
8. ∆DEF = ∆AMS by ASA
as , angle D = angle A, EF = MS , angle F = Angle S
9. ∆JKL = ∆HAT by SAS
as, JK = HA , KL = AT , angle L = angle T
10. ∆ABC = ∆KPG by ASA
as , CA = GK, Angle c = angle G and Angle B = angle P
11. ∆ABC = ∆YDE by ASA
as , angle A = angle Y, AB = YD , angle B = angle D
12. ∆MNO = ∆SAK by ASA
as , Angle M = angle S, NO = AK, angle O = angle K
