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
Answer:
72°
Step-by-step explanation:
Given that the radius(r) of the circle is 10 units and the length of arc ABC is 16π
The length of arc ABC = 
Where θ is the central angle in degrees.
Since the length of arc ABC is 16π,

The angle in a circle = 360°, therefore:
Central angle for arc AB (θ) = 360 - Central angle for arc ABC = 360 - 288 = 72°
Therefore the arc measure of arc AB is 72°
Answer: 4 kilograms of dough and will continue preparing 1 kilogram of dough every hour.
Step-by-step explanation:
Answer:let x be the number of cars, and 7-x be the number of trucks.
25x + 30(7-x) = 195
25x + 210-30x = 195
5x = 15
x = 3
So, 3 cars were not rented. If 7 total vehicles were not rented, 7 - 3 cars = 4 Trucks
4 Trucks were not rented.
