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%

<span>If the range of the answer should be +/- 10% of the particular value, then you have to solve for the percentage of that particular value. Since the value given is 1.8, we thus want to find 10% of that:
1.8 * 10/100 = 0.18
Then, add this value to the original value of 1.8:
1.8+0.18 = 1.98
Next, subtract .18 from from the original value of 1.8:
1.8-0.18 = 1.62
The range will be between these two numbers, so the range is from 1.62 to 1.98.</span>
If the length, height, and width of the volume are L, W, and H, respectively. Then the volume would be equal to V = L(W)(H) = LWH.
Given that the length and width have tripled, then the new length and width of the prism would be 3L and 3H. Thus, the volume of the new prism is V = (3L)(3H)(W) = 9LWH.
Comparing this to the original volume, we can clearly see that the volume has increased 9 times after the changes.
Answer: Volume becomes 9 times larger.
3x + 2y = 0
- 3x - 3x
2y = -3x
2 2
y = -1.5x
The gradient of the straight line of the function is -1.5.
