The average is 130 parts per hour.
Step-by-step explanation:
Given,
Parts being made at factory = 521
521 parts are made in = 4 hours
Average parts per hour = ![\frac{Parts\ made}{No.\ of\ hours}\\](https://tex.z-dn.net/?f=%5Cfrac%7BParts%5C%20made%7D%7BNo.%5C%20of%5C%20hours%7D%5C%5C)
Average parts per hour = ![\frac{521}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B521%7D%7B4%7D)
Average parts per hour = 130.25 parts
Rounding off to nearest whole number
Average parts per hour = 130 parts
The average is 130 parts per hour.

5 x 21 = 1.05 10 x 12 = 1.20
Nickels: 21 Dimes: 12
1.05 + 1.20 = 2.25
If I had 25 nickels, I would have 12 dimes, and a extra 5 cents.

Answer:
Car A blinks 36 more times than Car B
Step-by-step explanation:
To figure out how many times Car A blinks, you have to divide 60 / 5 which equals 12. Since it blinks 7 times per 5 seconds, you would have to multiply 7 by 12, which equals the answer for the first part, 84 times per minute.
To figure out many times Car B blinks, it's the same way. But this time, you multiply 12 by 4, since it blinks 5 times every 4 seconds. Which in that case is 48 times per minute.
So, 84 - 48 = 36 times more than Car B
