Answer:
0.9%
Step-by-step explanation:
We have been given that Rich measured the height of a desk to be 80.7 cm. The actual height of the desk is 80 cm.
We will use percentage error formula to solve our given problem.
Therefore, Rich's percent error in calculation is 0.9%.
Answer:
Equation of line 1 is 3 X - 4 Y = 20
Equation of line 2 is 3 X + 4 Y = 20
Step-by-step explanation:
Given co ordinates of points as,
( -4 , 8) and (0 , 5)
From the given two points we can determine the slop of a line
I. e slop (m) =
Or, m =
So, m =
Now equations of line can be written as ,
Y - y1 = m ( X - x1)
<u>At points ( -4 , 8)</u>
Y - 8 = (X + 4)
So , Equation of line 1 is 3 X - 4 Y = 20
<u>Again with points ( 0 , 5)</u>
Y - 5 = ( X - 0)
So, Equation of line 2 is 3 X + 4 Y = 20
Hence Equation of line 1 is 3 X - 4 Y = 20 and Equation of line 2 is 3 X + 4 Y = 20 Answer
The answer is c so i would pick that beacuse its sounds like a correct answer.
