Hey there! I'm happy to help!
We see that Noah rides his motorcycle 90 miles is 2 hours and 30 minutes, which is 150 minutes. We want to find his mph. To find this his mph, we want to find how far he has gone in one hour.
How much bigger is 150 than 60?
150/60=2.5
150 is 2.5 times bigger than 60. This means that we need to divide 90 by 2.5 to figure out how far Noah rode in 1 hour.
90/2.5=36
Therefore, Noah's average speed is 36 mph.
Have a wonderful day! :D
Answer:
a) To find the other missing length we must be given an area and a length
We then divide the total area by the given length
so
6534/99 = 66 is the missing width
Given:
The graph of a function.
To find:
The domain and range of the given graph.
Solution:
Domain is the set of x-values or input values.
From the given graph it is clear that, the graph is defined for the interval (-4,4).
But there is a closed circle at x = -4 and an open circle at x = 4. It means, -4 is included and 4 is not included in the solution set.
Domain: [-4,4)
Domain: 
Range is the set of y-values or output values.
From the given graph it is clear that, the output values are lie in the interval (-3,4).
But there closed circle at x = -3 and x = 4. It means, -3 and 4 are is included in the set of output values.
Range: [-3,4]
Range: 
Therefore, domain is
and range is
.
