Your answer of "Answer.12= 4/6" makes no sense, 12 ≠ 4/6, nor does it actually answer the question. Jane ate 4/6 or 8/12 of the pizza. Since the pizza had 12 slices, she ate 8 of them. So Eric must have eaten 4 slices.

Thank you for using the Jiskha Homework Help Forum. What are you asking for? If it is a synonym of "dynamics" you should state that. It is not in the Thesaurus, but "dynamic" is: Main Entry: dynamic Function: adjective Text: 1 having active strength of body or mind <a ...

Dynamics
F(force)= dP/dt (rate of change of momentum) So, F*dt(impulse)= dP (change in momentum in the small time dt) If impact means force, then the force multiplied by the time duration it is applied on a body equals impulse.

Math
12 x + 8 = y^2 - 4 y add 4 to both sides 12 x + 12 = y^2 - 4 y + 4 so (y-2)^2 = 12 (x+1) = 4*3 (x+1) opens right vertex at (-1,2) focus to vertex = 3 so focus at (2,2) directrix to vertex = 3 so directrix at x = -4

1.Increasing the resistance by a factor of 15 means multiplying the resistance by 15. Since the current is inversely proportional to the resistance,when the resistance is multiplied by 15, the current is divided by 15. So the current is decreased by a factor of 15. 2. ...

x^2+x=12 Since you do not ask a specific question, I assume that you want to find the factors. x^2 + x - 12 = 0 From the above, for the center term, you are looking for two values whose product is -12 and whose sum is +1. (x + 4)(x - 3) = 0 I hope this helps. Thanks for asking.

Let the middle number be x, then the first would be x-1 and the largest would be x+1 so (x-1)(x)(x+1) = -1716 x(x^1 - 1) = -1716 x^3 - x + 1716 = 0 Looking at that tells me that x would be around the cube root of 1716 which is approximately 12, since you said "integer" I will ...

Quiz style answer: Take half and half, if there is too much, change a 12 for a 6. 5*6+5*12=90, 6 volts too much, so it is 6*6+4*12=84. Serious answer: Let S = the number of 6 volts be 10-S = the number of 12 volts 6S + 12(10-S) = 84 Solve for S.

Because Torque is a cross product of radius vector(r) and Force vector(F). If r =Ax+By+Cz & F = ax+by+cz (where x,y and z are unit vectors in x,y and z directions) then x-component of torque Tx is : Tx = (Bc-Cb) = 3*0-3*4 = -12 Therefore x-comp. of the Torque is nagative (-12)
