Answer:
4x+5 ft
Step-by-step explanation:
1/2(4x²+29x+30) = 1/2 (x+6) * Height
Height = (4x²+29x+30) / (x+6) = (x+6) (4x+5) / (x+6) = 4x+5
There would be 260 lifegurads
The easy way is to divide 18.2 by 0.07 to get your answer
If my answer is wrong pls let me know i try my best to edit and make it right
Triangle A:
y = 57.5°
x = 57.5°
Triangle B:
y = 5
x = 6.5
Triangle C:
... I apologize but I do not know what Triangle C is. Sorry!!
Triangle D:
z = 30°
x = 90°
(x+20) = 110°
SORRY THAT TOOK SO LONG--
The angles of a triangle always equal to 180 degrees.
Knowing this, you can solve this by this equation
Angle A + Angle B + Angle C = 180
43 + 85 + Angle C = 180
Angle C = 180 - 43 - 85
Angle C = 52
Class B has the most consistant sleep because there is less of a difference between 6.87 and 3.65 than the other classes.
