Answer:
Mass of planet B is larger than A by 500 times
Step-by-step explanation:
Mass of planet A= 8*10^24
Mass of planet B= 4* 10^27
Larger Mass= Mass of planet B
Mass of planet B/Mass of Planet A= 4* 10^27/8*10^24
=1*10^(27-24)/8
=(1*10^3)/2
=1/2*10^3
=1000/2
Therefore by, 500 times.
-3x/2 - 9 = -27
-3x/2 = -27 + 9
-3x/2 = -18
-3x = -18 * 2
-3x = -36
x = 36/3
x = 12
*negative thirty-six turned into negative thirty-six over three, but since both numbers were negative, we had to make it positive in order to simplify, so that's why the answer is twelve, and not negative twelve.
Answer:
-9:8
Step-by-step explanation:
8-1-(18-2):8
Subtract 2 from 18
8-1-16:8
subtract 1 from 8
7-16:8
subtract 16 from 7
-9:8
The vertical height traveled is given by
h = ut +- (1/2)g*t^2
where
u = 57 ft/s, initial speed
t = tme, s
g = 32 ft/s^2
After 3 seconds,
h = (57 ft/s)*(3 s) - (1/2)*(32 ft/s^2)*(3 s)^2
= 171 - 144
= 27 ft
Answer: 27 ft
