Answer:
- 16,965 mm/min
- 90π ≈ 282.7 radians/min
Step-by-step explanation:
The circumference of the CD is ...
C = πd
C = π(120 mm) ≈ 376.99 mm
This is the distance a point on the edge of the CD will travel when making one revolution. It will travel 45 times this far when making 45 revolutions:
(376.99 mm/rev)(45 rev/min) ≈ 16,965 mm/min
__
There are 2π radians in each revolution, so the angular speed is ...
(2π rad/rev)(45 rev/min) = 90π rad/min ≈ 282.7 rad/min
The answer is 1500g. There are 1000 grams in a kilogram so 1.5 x 1000 = 1500.
Answer:
`18. x=9

21. x=3
22. x=3,5
23. x=10
Step-by-step explanation:
If Blake knows that one of the answers to x2, then the only correct answer there is is X equals four
Answer:
0.69*100=69
3/13=4.3= 4.3*100= 430
Step-by-step explanation:
All you are doing is taking the number and transforming it, if it is a decimal then multiplying the decimal by 100 and you get ur answer. When you are doing a fraction, you need to change it into a decimal and do the same.
I hope this helped you :)
