40 = 5%
? = 100%
To find the ? you multiply 40 by 20 to get 800 people.
Answer:
see below
Step-by-step explanation:
cos(420°) = cos 60 = 1/2
sin(450°) = sin 90 = 1
120 degrees the sum of all is 720
9We have such eqation
Q

/*9 (multiply both sides by 9)
9Q+5=

/-5 both sides
9Q=

9Q=

9Q=

9Q=-

/:9 divide both sides by 9
Q=-

Q
![\frac{21}{6*9} =- \frac{21}{54}=[tex] \frac{7}{18}](https://tex.z-dn.net/?f=%20%5Cfrac%7B21%7D%7B6%2A9%7D%20%3D-%20%5Cfrac%7B21%7D%7B54%7D%3D%5Btex%5D%20%5Cfrac%7B7%7D%7B18%7D%20)
- its the answer
Add 26 and 73 = 99 then divide 99 by 6 = 16.5 which is 17 vases
