Answer:
Mr. Nelson paid $48 befor tax.
Step-by-step explanation:
Let x be the price of the item before tax.
108 % * x - x = 3.84 (the tax itself)
27/25x - x = 3.84
2/25 x = 3.84
x = 48
The opposite of twelve is negative twelve.
Answer:
The hummingbird beats its wings 86 400 times in one hour.
Step-by-step explanation:
There are 60 minutes in an hour. There are 60 seconds in a minute.
1h = 60m
= 60 × 60s
= 3600s
1s = 24 times
3600s = 24 × 3600
= 86 400 times
Volume of right circular cone = 1/3 πr^2h
Since 2=3
And 3 and 7 are on a straight line so they add up to 180
You can say : x+ 2x= 180
3x=180
x=180/3
x= 60
Angle 2 is 60
