You have 2 angles measurements of 16 degrees and 80 degrees 16+80=96. So now you need it to add up to 180 so do 180-96 which equals 84.

So your answer is B.84

Answer:

Option C is correct

The most precise measurement is, $\frac{2}{32}$ in

Explanation:

A numbers after the decimal point is a fraction of the number 1.

Therefore, more numbers you have after the decimal the smaller the fraction, and more precise that fraction will be.

Given: $\frac{2}{32}$ in , $\frac{3}{12}$ in , $\frac{1}{12}$ ft or $\frac{1}{36}$ yd

First convert : $\frac{1}{12}$ ft into inches

Use conversion: 1 ft = 12 inches

then,

$\frac{1}{12}$ ft $\rightarrow$ $\frac{1}{12} \times 12$ in =1 in

Similarly, Convert $\frac{1}{36}$ yd into inches.

Use conversion: 1 yard = 36 inches

then,

$\frac{1}{36}$ yd $\rightarrow$ $\frac{1}{36} \times 36$ in = 1 in.

Now, convert all the fraction $\frac{3}{32}$ in , $\frac{3}{12}$ in , 1 in or 1 in. into decimal.

$\frac{2}{32}$ in = 0.0625

$\frac{3}{12}$ in = 0.25 in.

1 in.

From the above only 0.0625 in. is the most precise.

Find the number of permutations of the first 10 letters of the alphabet, taking 3 letters at a time.

allsm [11]

Answer:

720

Step-by-step explanation:

The permutation looks like this for that set of data:

$_{10}P_{3}$

and the formula to solve it like this:

$_{10}P_{3} =\frac{10!}{(10-3)!}$

which simplifies down to

$_{10}P_{3} =\frac{10!}{7!}$

Since every number less than 8 in the numerator cancels out with the denominator, we have

$_{10}P_{3}=10*9*8$

which equals 720
