I recorded a video of myself explaining it hope it helps ;)
Step-by-step explanation:
Answer:
1 /1 ; 360°
Step-by-step explanation:
Start time = 2:30 pm
Stop time = 3:30 pm
Minute hand makes a complete revolution per hour ;
This means that the minutes hand revolves round the whole circle in one hour, hence fraction of the circle covered by the minute hand between 2:30 pm - 3:30 pm is 1/1 = 1
The angle turned by the minutes hand :
1 complete revolution = 360°
A circle covers 360°
1 /1 fraction of a circle = 1/1 * 360° = 360°
Hence, angle turned by the minute hand = 360°
replace the numbers given for x & y so
the equation becomes 3*(-3) + 2*(-4) =
3*-3 = -9
2*-4 = -8
-9 + -8 = -17
The ratio between the masses of Jupiter and Venus is
We can separate the coefficient and the powers of ten:
Use the exponent rule
to simplify the powers of 10:
So, the ratio is
So, Jupiter has a mass that is approximately 400 times greater than Venus's.
