15.31

Step-by-step explanation:

solve both sides separately

6x+78/67-78x

x cancles out

becomes 84/-11

becomes -7.64 rounded

the case of napkins contained 45 packs with a total of 10,125 napkins. each napkin contained the same number of napkins. write a
Pavlova-9 [17]
You would need to do 10,125/45 = n, and in which case we just solve. 
10,215/45=227, so there are 227 napkins in each box.


Hope this helps and have a nice day:)

Find the coordinates of the point (a, b).
Leviafan [203]

Answer:

a = \frac{1}{\sqrt{2} } and b = \frac{\sqrt{2} }{2}

Step-by-step explanation:

As we know, the radius of the unit circle is 1 unit (it is the hypotenuse in the right triangle, the blue line)

We use trigonometric formulas to find out a and b

  • Sin(45) = opposite side / hypotenuse

<=> Sin(45) = b / 1

<=> b= Sin(45)*1 = \frac{\sqrt{2} }{2}

  • Cos(45) = adjacent side / hypotenuse

<=> Cos(45) = a / 1

<=> a =  Cos(45)*1 = \frac{1}{\sqrt{2} }

So: a = \frac{1}{\sqrt{2} } and b = \frac{\sqrt{2} }{2}
