The answer is the second option, 52°.

To find the answer, I plugged the different answer options into my calculator until I found the one that was equivalent to what the question was asking for.

Alternatively, you could take the inverse cosine of 0.616 to solve for the angle whose cosine is equivalent to that number.

Answer:

$24.3

15% of 18 = 0.15 x 18 = 2.7

Cost of Dinner:

Tip + Cost of meal = total price

2.7 + 18 = 20.7

Money Remaining:

45 - 20.7 = 24.3

Missing part of the question

Determine the number of handshakes, i, that will occur for each number of people, n, in a particular room. (people)

Answer:

$S_n = \frac{n}{2}(n - 1)$

Step-by-step explanation:

Given

For 5 people

$\begin{array}{cc}{People} & {Handshakes} & {5} & {4} & {4} & {3} & {3} & {2} & {2} & {1} & {1} & {0} &{Total} & {10} \ \end{array}$

Using the given instance of 5 people, the number of handshakes can be represented as:

$(n - 1) + (n - 2) + (n - 3) + ........ + 3 + 2 + 1 + 0$

The above sequence is an arithmetic sequence and the total number of handshakes is the sum of n terms of the sequence.

$S_n = \frac{n}{2}{(T_1 + T_n})$

Where

$T_1 = n - 1$ --- The first term

$T_n = 0$ --- The last term

So:

$S_n = \frac{n}{2}(n - 1 + 0)$

$S_n = \frac{n}{2}(n - 1)$

to read a book. It's .10 + .15 = 25%.

C) 70 females were surveyed out of 200 people.

Explanation) Add up .15 + .5 + .15 to get .35. Put .35 multiplied by 200 to get 70.
