Answer:
its most likely A
Step-by-step explanation:
Considering it goes at a steady rate with the second variable being reasonably scattered, the level of pure water would obviously go down not up,considering you are adding frogs. than again i havent really reached this degree of mathematics. But through reasoning i beleive it's A
Volume of a cone = (1/3) pi x r^2 x h
Volume of a cylinder = pi x r^2 x h
Volume of the cylinder = pi x 2^2 x 3 = 37.68 cubic inches
Now set the volume for the cone to the volume of the cylinder and solve for the height.
37.68 = (1/3) x pi x r^2 x h
37.68 = (1/3) x pi x 3^2 x h
37.68 = (1/3) x pi x 9 x h
37.68 = 9.42 x h
h = 37.68 / 9.42
h = 4
The height of the cone is 4 cm.
Answer:
Willie: 78 pounds
Ray: 118 pounds
Timothy: 130 pounds
solution: Let willy be x pounds
Ray : 40 + x pounds
Timothy: 12+(40+x) pounds
x+40+x+12+40+x=326
3x+92=326
326 - 92 =3x
234 = 3x
x = 234/3
x= 78
Willie weights 78 pounds, Ray weights 118 pounds, and Timothy weights 130 pounds..
this is ur answer hope it helps....
Answer:
44.40
Step-by-step explanation:
The correct answer is C and E
Explain
A. 8x+4x=0
Now simply it
12x = 0
Now divide by 12 on both both side
X= 0
So this equation has the solution x= 0
B. 6x+2 = 4x+2+2x
Now both sides
6x+2=6x+2
Now simply by 6x+2 both sides
X= 0
So this equation has infinity solution
C. 4x-8x-3=6-4x
Now simply both sides
-4x-3=6-4x
Now simply
-3x=6
This equation have no solution
D. 5x+1 =1-5x
Now add 5x-1 on both sides
10=0
Now divide by 10
X= 0
This equation have solution x= 0
E. 12x-3-5x = 9+7x-6
Now simply both sides
7x-3= 7x+3
And subtract 7x from both sides
-3 = 3
So the equation has no solution
I hope this help you :D
Good luck
