Letter E is correct.
Area of equilateral trianlge= (1/2) tiime a^2 square root 3
Equation for the base is = x^2+y^2 =9
at x ,
y= square root (9-x^2)
Side of triangle a= 2y
d times Volume = (1/2)a^2 square root 3 dx
d times V= (square root 3) (9-x^2) dx
V= square root 3 INT (9-x^2) dx
-3V= 2square root INT (9-x^2) dx
0
V= 2 square root 3 ( 9x-x^3/3)
V=2 square root 3 ( 27-9)
V= 36 square root 3
The answer is E.
Im thinking 8 and a half but could be wrong
Answer: 30 pounds
Step-by-step explanation:
Let the weight 3 month ago be X.
20% more than x is:
1.2x
We now have the following equation:
1.2x = 36
x = 36/1.2
x = 30 pounds
Hope that helps! Have a good day :)
90/135 = 0.666666667
0.666 x 100 = 66.6 %
