Length of train : 100
length of bridge : 400
distance covered by the train to cross the bridge : (100 + 400) = 500
time taken by the train to cross : 30
speed = distance / time
speed = 500/30
speed = 16.67 meters per second <===
An addition sign between 978 and 842 would make the equation true!
Exponent rules : (a^m)^n = a^(mn) and a^0 = 1
(4^9)^5 * 4^0 =
4^45 * 1 =
4^45 <==
Answer:
A=B*H
Step-by-step explanation:
multiply B (base) by H (height)
2 ounces
using the conversion
1 pound = 16 ounces ⇒
= 8 ounces
