Answer:
64.6 km/h
Step-by-step explanation:
18:14 = 18h 14'
1h = 60'
18h = 17h + 60'
18h14' = 17h + 60' ´14' = 17h 74'
then:
17h 74'
-17h 22'
= 0h 52'
the train travelled 56km at 52 minutes
56km/52minutes
1 hour = 60 minutes
52 minutes = 52/60 = 0.86667 hours
then:
56km/52minutes = 56km/0.86667hours
= 64.615 km/hours
(a^3b)^2 • 4ab^3
a^6b • 4ab^3
4a^6b+1b^3
You are given
z+9/2 = -3. You are required to get the value of z. Since the equation is an example
of an equality, you can easily get the value of z. The solution of the problem
is,
Z + 9/2 = -3
Z = -3 – 9/2
<u>Z = -15/2
or -7.5</u>

Answer:
45°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosB = 
= 
= 
, hence
B = 
( ) = 45°
