<h2>Answer:</h2>

The total number of handshakes that would happen between the three people are:

                                    3

<h2>Step-by-step explanation:</h2>

There are three people at a party.

Let they be denoted by A,B and C.

Now, the total number of handshakes that would occur will be denoted by:

      AB, AC and BC

where AB denotes that A and B shake hands.

AC denote that A and C shake hands.

and BC denote that B and C shake hands.

Hence, total number of handshakes are:

                           3

Which is larger 12 1/6 or 75/6
xz_007 [3.2K]

Hello there! Your answer would be 75/6 is larger than 12 1/6.

Need an Explanation?:

Divide 75 by 6 to start so we can equally look at the numbers.

75/6 = 12.5

We know that .5 is equal to 1/2, so change .5 to 1/2.

That means we now have 12 1/2.

So, which is larger: 12 1/6 or 12 1/2?

Obviously 12 1/2 is larger, so this is the one you should choose.

<em>I hope this helps, and have a great day! Please don't hesitate to ask if you need more help with this specific question! </em>

tigry1 [53]

8.25 hours is our base number here. 1/3 of it is taken up when he stops at the gas station.

8.25, 4.125 is half of it, 2.75 is our answer for this,

8.25/3 gives you 2.75 due to 2.75 making it 5.5 when doubled and so on

so, the answer is 2 3/4 hours, D

Find the exact values of x and r
NemiM [27]

Answer:

Below

Step-by-step explanation:

You can use sine law to solve this : sina / A = sinb / B

We will first find side x

We know that since this is a special triangle that side will = 28, but we can prove this mathematically :

sin(45) / 28 = sin(45) / x

= 28 sin(45) / sin(45)

x = 28

Now to find side r just use Pythagorean theorem a^2 + b^2 = c^2 :

c^2 = 28^2 + 28^2

      = 1568

Square root this number

r = 39.597

The just round to however your teacher wants

If you didn't already know about special triangles, an isosceles right triangle like this one has a ratio which is the two legs will equal each other, while the hypotenuse is √2a . You could have also used this to solve.

Hope this helps! Best of luck.

Ayo can y’all help? No rush but it’s 25 points with brainliest
Sergio [31]

You know the answer is the third choice (C) because 7^2 is 49 and 8^2 is 56, the two closest squared numbers to 54.

49 < 54 < 56

The square root of 54 is  roughly 7.4

I hope that helps :)
