<h3>Answer: 12</h3>

Explanation:

Multiply 0.66666667 with 18 to get

0.66666667*18 = 12.00000006

The 6 at the very end is due to rounding error. In reality the 6's in 0.66666667 should go on forever. That 7 is from rounding up.

Anyways, the result 12.00000006 should be 12 exactly.

Note how

12/18 = 0.66666667

when using a calculator.

When the dilation is centered on the origin, you can multiply each of the individual coordinates by the scale factor.

All the coordinates are ±5 and the scale factor is 1/5. Multiplying those gives ±1. The only selection with all coordinates being ±1 is
.. Selection A.

You can check to see if the signs agree in detail. (They do.)

satela [25.4K]

Answer:

The answer is B. 14.7%.

Step-by-step explanation:

Given:

Estimated time need to complete project 17h.

Actually time needed 19\frac{1}{2}h=\frac{39}{2}h.

Difference between the time ET-AT= \frac{39}{2}- 17\\=\frac{39}{2} -\frac{34}{2}\\ =\frac{5}{2}=2.5h.

So, the percentage error is \frac{2.5}{17}\times100\\ =\frac{250}{17} \\=14.70%.

Therefore, the answer is B. 14.7%.
