Answer:
9.43 m/s
Step-by-step explanation:
Fred runs 200 metres in 21.2 seconds
FIND: Work out Fred’s average speed
aver speed =<u> 200 m </u>
21.2 s
= 9.43 m/s
8 . 9 10^(5+3) is the answer (B)
The 8 and 9 are multiplied and you add the exponents when you multiply 10^3 and 10^5.
19-2x=3x-16
19+16=3x+2x
5x=35
Therefore, x=7.
19-2x=3x-16
19+16=3x+2x
5x=35
Therefore, x=7.
As angle /_ABC is 19-2x,
angle /_ABC is 19-2(7)=5.
20397 / 1000
