Free_Kalibri [48]3 years ago
7 0

Answer:

28

Step-by-step explanation:

So in order to get this answer you want to use the combination formula which is \frac{n!}{(n-r)!r!}

Now you want to use the numbers given to you in the problem which is ₈C₂ and plug those into the equation

so your going to have something looking like this \frac{8!}{(8-2)!2!}  now if you have a calculator nearby and you plug in ₈C₂ your going to get 28 which is the answer.

hope this somewhat helps.

The first thing we do in a problem like this is let arc AB equal X. X is the magic letter, anything you need to find name it x. We also know that all arcs in a circle must add up to 360, so arc ALB is equal to 360 - x.

There's this theorem saying that when two tangents intersect from a point outside a triangle, the measure of the angle formed by the intersection of the tangents (angle P) is equal to the half the difference of the arcs. 
This basically means:

angle P = 1/2(360 - x) - x.
plug in the value of angle P
84 = 1/2(360 - x - x)
168=360 - 2x
2x = 192
x = 96

arc AB=96

Suppose Carson worked as a babysitter for '8' hours one week. What is the minimum number of full hours he would need to work at
liubo4ka [24]

Answer:

The minimum number of full hours did Carson need to work at his father's business is 8 hours and 15 minutes  

Step-by-step explanation:

Given as :

The total number of hours did Carson spent as baby sitting on one week = 5 hours

The rate at which he earn for baby sitting = $6 per hours

The rate at which he earn as job = $8 per hours

The total amount he will earn that week = $96

Let The minimum number of full hour he need to work = h

Now, According to question

The total amount he will earn that week = total number of hours did Carson spent as baby sitting on one week ×The rate at which he earn for baby sitting  + The rate at which he earn as job × The minimum number of full hour he need to work

I.e $96 = $6 × 5 + $8 × h

Or, $96 = $30 + $8 × h

Or, 8 × h = 96 - 30

Or, 8 × h = 66

∴  h =  

i.e h = 8.25 hours

So, The number of hours = h = 8 hours and 15 minutes

Hence,The minimum number of full hours did Carson need to work at his father's business is 8 hours and 15 minutes  .
