Answer:
54
Step-by-step explanation:
144 divided by 8 is 18
so that means that their hourly rate 18 pizzas per hour
so multiply 18 by 3 and get 54
If you start with all the sides of the hexagon being congruent, you can then figure out angle measures, then you can conclude that all the sides of polygon GBHE are congruent, so it is a rhombus.
Each angle at vertices H and G measures 120 deg.
Each angle at vertices E and B measures 60 deg.
Answer:
6.4 kmph
Step-by-step explanation:
12.8/2=6.4 kmph
The first step in solving this question is to split the journey into 2 parts. In the first part of the journey, 
miles are covered at a speed of 40 mph. In the second part the journey 5 miles are covered at a speed of 60 mph.
The equation to compute the time of a journey given the speed and distance is 
where 
is the time, 
is the speed and 
is the distance.
The time for the first part of the journey is calculated as shown below,
.
The time for the second part of the journey is calculated as follows,
.
The total time is the sum of the times taken to cover each part of the journey and is calculated as shown below,
The time to cover the journey is a third of an hour or 20 minutes.
Convert it into the y=a(x-h)+k form and the values of h and k are your vertex.
You can convert by completing the square method.
