Answer: 40
Step-by-step explanation:
You will take the miles he drove and divided it by the time it took him to get there
320/8=40
44.44
%
Explanation:
Take the absolute value of the difference fof the two and then divide by the first number:

Step-by-step explanation:
Given:
2x−y=7
Matching given equation with the variables,
a=2
and
b=−1 .
Swap "a" and "b"
-x + 2y = 7
Because b is negative, let's change that one:
x + 2y = 7
Is perpendicular to
2x−y=7
. Here is a graph to prove it:
The red line is
2x−y=7
The blue line is
x+2y=7
If you want the perpendicular line to go through a given point, then make the constant term on the right a variable (for example k)
x+2y=k
Now lets make the perpendicular line go through the point
(1,1)
by substituting 1 for x, 1 for y and the solving for k:
1+2(1)=k
k=3
The equation of the line that perpendicular to
2x−y=7 and goes through the point
(1,1)is:
x+2y=3
Please mark me as brainleist.
A² = b² + c²
30² = 18² + 24²
18, 24, 30
see screenshot
general formula is
r² = (x - x-center)² + (y - y-center)²
note that I choose a radius of 6 arbitrarily. you didn't provide the information about the radius, but just put in yours
