Answer:
The voume of the cylinder is (pi)(x^2)(y)
Voulne of the cone is (1/3)(pi)(3x)^2(h). H is the unknown height of the con2
Since the volumes are equal
(pi)(x^2)y = (1/3)(pi)(9x^2)h
h= y/3
Step-by-step explanation:
If the ratio of boys to girls is 11:9 and there are 124 more boys than girls:
Let's say that the number of boys is 11x and the number of girls is 9x.
So, 11x = 9x + 124
2x = 124
x = 62
The total number of students = Number of boys + number of girls
= 11x + 9x
= 20x
= 1240 students
Thus, the total number of students attending the school is 1240.
Answer is A.
You start by adding the 7 to the opposite side. Giving you 19. You divide both sides by -2 which gives you x on one side and -9.5 on the other.
-2x-7=12
-2x=12(+7)
-2x=19
x=19/-2
x=-9.5
Answer: just plug in the values it gives you and then it's simple addition and subtraction.
