Answer:what grade is this
Step-by-step explanation:
Answer: If he gives Al 42, then he gives Bob 21 and Carl 84. Do those add up to 210? 42 + 21 + 84 = 147–that’s too small! Go bigger.
Step-by-step explanation:
So Since (D) is odd, shoot right to (E). If he gives Al 60, then he gives Bob 30 and Carl 120. Does that add up to 210? Yes, yes it does. 60 + 30 + 120 = 210.
Answer: 750 Joules.
Step-by-step explanation:
Use the equation: K = 1/2 x m x s^2
1/2 x 60 = 30.
30 x (5 x 5) 25 = 750
Lance's kinetic energy when he runs at this speed is 750 Joules.
Answer:
m = 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 4x + 7 is in this form with slope m = - 4
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
=
Hence the value of m =
