Alan needs to drive 400 miles to reach Madison. He is driving at a constant speed of 55 miles per hour. The function y = 400 − 5
5x represents Alan’s distance in miles from Madison in terms of the number of hours he drives. Andrew is also driving at a constant speed to reach Madison. The table represents Andrew’s distance in miles from Madison in terms of the number of hours he drives.
1 answer:
Question is not written properly but i think you are looking for the table of given equation y=400-55x. So I will explain about how to get that.
number of hours can't be negative so that means x must be 0 or more.
like x=0,1,2,3,...
we just have to plug these x-values into above equation to find the y-value in order to calculate table.
I will show you calculation for x=2
y=400-55x=400-55*2=400-110=290
so the point in table will be (2,290)
similarly we can find more point and get final table as shown below:

Answer:
Step-by-step explanation:
Volume of a cone:
Take as 3, as mentioned in the question
'r' is 'radius' ⇒ {diameter is given so divide by 2: 12/2 = 6}
'h' is 'height'
{multiply 108 with 5 and then divide the answer by 3}

Answer:
m = 10
Step-by-step explanation:
Given w is inversely proportional to m then the equation relating them is
w = ← k is the constant of variation
To find k use the condition w = 8, m = 25 , then
8 = ( multiply both sides by 25 )
200 = k
w = ← equation of variation
When w = 20 , then
20 = ( multiply both sides by m )
20m = 200 ( divide both sides by 20 )
m = 10
This is the answer .
