Answer:
Step-by-step explanation:
To find an equal ratio, you can either multiply or divide each term in the ratio by the same number (but not zero). For example, if we divide both terms in the ratio 3:6 by the number three, then we get the equal ratio, 1:2.

D) Indefinatley Many
Step-by-step explanation:

One revolution is completed when a fixed point on the wheel travels a distance equal to the circumference of the wheel, which is 2π (13 cm) = 26π cm.
So we have
1 rev = 26π cm
1 rev = 2π rad
1 min = 60 s
(a) The angular velocity of the wheel is
(35 rev/min) * (2π rad/rev) * (1/60 min/s) = 7π/6 rad/s
or approximately 3.665 rad/s.
(b) The linear velocity is
(35 rev/min) * (26π cm/rev) * (1/60 min/s) = 91π/6 cm/s
or roughly 47.648 cm/s.
A) -3.5*2^2*3=-14*3=-42
c) -3*y*z^2=-3*(-4)*3^2=12*9=108
6x*y^2=6*2*(-4)^2=12*16=192
P=2*(108+192)=2*300=600
b) 5/2*(-4)^2=5/2*16=40
