Answer:
5% each hour
Step-by-step explanation:
in 1.5 hours she loses 7.5% of battery
get the percentage of loss for a half hour.
divide 1.5 and 7.5 by 3.
That gives a loss of 2.5% for every half hour.
Which gives a loss of 5% percent an hour.
36 + h = 75...subtract 36 from both sides
h = 75 - 36
h = 39
-176 = h + (-219)
-176 = h - 219....add 219 to both sides
219 - 176 = h
43 = h
Not sure how simplified you need it...

The answer is probably 590,000 because isn't it subtraction
Answer:
The actual speed of the car is either 57 mph or 63 mph
Step-by-step explanation:
Given as :
The measured speed o the car = 60 mph
The percentage error in speedometer = 5 %
Let The actual speed of car = x mph
Now, percentage error =
× 100
So,
= 
or,
× 60 = x - 60
Or, 3 = x - 60
∴ x = 63 mph
Hence The actual speed of the car is either 57 mph or 63 mph . Answer
