Answer:
(2,4)
Step-by-step explanation:
I painfully counted every square to find that a 1 by 1 square is divided into an 8 by 8 square.
K is one square above 1/2, for the second coordinate is 4.
K is also 2 to the left of 0, so the first coordinate is 2.
Therefore, the coordinates of K are (2,4).
How much is 1 foot in 1 centimeters?
First we need to know:
1 foot = 12 inches
1 inch = 2.54 cm
Those are the things that we need to know beforehand.
Then, we can start converting.
= 1 ft * (12 in / 1 ft) * (2.54 cm / 1in)
= 30.48 cm
So 1 foot is just equal to 30.48 cm
The percent error of Shirley's estimate is 21.74%
<h3>Calculating pecent error</h3>
Given the following parameters
- Actual length = 23 inches
- Estimated length = 18in
% error = actual-estimated/actual * 100
% error = 23-18/23 * 100
% error = 500/23
% error = 21.74%
Hence the percent error of Shirley's estimate is 21.74%
