A restaurant manager recorded the drinks ordered by 150 customers. Each customer ordered one drink. The results are shown in the circle graph below. How many customers ordered juice, tea or water?

82% of people ordered juice, tea, and water

Step-by-step explanation:

123 customers

Step-by-step explanation:

12%tea+30%juice+(100-12-30-18=40) 40% water=

82%

82% of 150

150*0.82

123

The problem is as follow: which of the following is an extraneous solution of √(4x + 41) = x+5 a. x=-8 b. x=-2 c. x=2 d. x=8 solution: √(4x + 41) = x+5squaring both sides∴ 4x +41 = (x+5)²∴ 4x +41 = x² + 10x + 25∴ x² + 6x - 16 = 0∴ ( x + 8)( x - 2) = 0∴ x = -8  or    x = 2by substitution in the given equation: substitute with x = -8left hand side =√(4*-8+41) = √9 right hand side =-8 +5 = -3the basic principal of the square root is to give a positive answer.so, x =-8  ⇒ is not an extraneous solutionsubstitute with x = 2left hand side =√(4*2+41) = √49 right hand side = 2+5 = 7∴ x=2  ⇒ is an extraneous solutionthe correct choice is option  (c)c. x = 2
