Answer:

G. \frac{3.2}{2} = \frac{a}{8}

Step-by-step explanation:

Given that figure I and figure II are similar, it follows that the ratio of their corresponding side lengths are equal and the same.

Thus:

\frac{3.2}{2} = \frac{a}{8} = \frac{8}{5} = \frac{6.4}{b}

Therefore, the proportion that must be true is:

✔️\frac{3.2}{2} = \frac{a}{8}

 what is 16/10 as a mixed number in simplest form. I don't get it?
Ivenika [448]
16/10 as a mixed number is 1 6/10.

I got this answer by finding out how many times 10 goes into 16, evenly. I got 1, and put that as a whole number. 6 was leftover, so I put that for the numerator. Then, I kept the denominator same, which was 10.


1 6/10 simplified is 1 3/5.

I got this answer by finding out what number goes both into 10 and 6, evenly. The GCF, or Greatest Common Factor, was 2. I divided 6 by 2 and 10 by 2. I then got 3 and 5.
3 was the numerator, and 5 is the denominator.

Again, 16/10 in simplest form is 1 3/5.

The dimensions of a rectangular piece of paper are 8.5 inches and 11 inches. Veronica folded the piece of paper along its diagon
Mashutka [201]

Answer:

D) 13.9 in

Step-by-step explanation:

The diagonal of a rectangle is longer than the longest side. It will never be more than 42% of the shortest side longer than the longest side.

Here, the longest side is 11 inches. 42% of the shortest side is about 3.6 inches, so the diagonal length will be between 11 and 14.6 inches. Only one answer choice is in that range: 13.9 in.

Of course, the length of the diagonal can be figured to any desired accuracy using the Pythagorean theorem.

... √(8.5² +11²) = √193.25 ≈ 13.9014 . . . . inches

_____

<em>Comment on the solution</em>

For this multiple-choice problem, it is sufficient to estimate the length of the diagonal. The estimate we suggested was to add 0.42 times the short side to the long side.

An even closer estimate can be had by multiplying that value (.42×short side) by the ratio of the short to long sides prior to adding it to the long side. This will get you within 1.5% of the correct value without the need for a square root.
