Answer:
The percent error in the speeds are 7.1428 %.
Step-by-step explanation:
The percent error of any value is found by,
<em>Here, the reading value is 60 mph and the correct value is 56 mph.</em>
Hence inserting this value in above equation, we get
<em>Hence, the percent error in the speeds are, 7.1428 %.</em>
For your first answer z=60 because 360/6
For your second answer y=128 you must add the two sides then subtract the answer from 360 to get 128
For your third answer for x=120 and 2x=100
<u>Answer:</u>
Slope = 6
<u>Step-by-step explanation:</u>
Taking two points on line l to find its slope: (0, 3) and (6, 2).
Slope of line l =
We know that the slope of a line which is perpendicular to another line has a slope which is a negative reciprocal of the other line.
Therefore, the slope of the line which is perpendicular to line l will have a slope of 6.
Answer:
(-19/2, -5)
Step-by-step explanation:
Given the two equivalent equations
4x – 9y = 7 .... 1
–4x + 6y = 8 ....2
Adding both equations
-9y + 6y = 7+8
-3y = 15
y = -15/3
y = -5
Substitute y = -5 into 1
From 1; 4x - 9y = 7
4x - 9(-5) = 7
4x + 45 = 7
4x = 7 - 45
4x = -38
x = -38/4
x = -19/2
Hence the solution is (-19/2, -5)
