1.50*12 = $18
18 < 1800 so that is not true, she made a mistake.
So 1 hour=60 min.,
So 10/1*60/1=600 min. That means 10 hours = 600 min.,
Then add the 39 min. to this equation= 639 min.,
Then you solve for the seconds, 24/1*1/60=0.4,
So 24 seconds is 0.4 (40%) of a minute,
Then it mean that it would take 639.4 minutes for Saturn to make a full rotation.
Hope This helps!!!

Answer:
At both 0.78 and 1.3 seconds, to the nearest hundredth, the ball will be at 20 feet.
Step-by-step explanation:
We can use two approaches to finding the answer: Calculation and Graphing.
<u>Calculation:</u>
Set h to 20 feet and solve the equation using the quadratic formula.
h= 4 + 33t - 16t^2
20= 4 + 33t - 16t^2
- 16t^2 + 33t + 4 = 20
- 16t^2 + 33t + -16 = 0
Solve using the quadratic formula. I find solutions of 0.779 and 1.28 seconds.
<u>Graphing:</u>
See the attached graph.
The ball is at 20 feet at 0.783 seconds on the way up and 1.28 seconds on the way back down.
===
Both approaches agree: 0.78 and 1.3 seconds, to the nearest hundredth, the ball will be at 20 feet.
<u>Answer:</u>
<h2>
A = 64.5 in²</h2>
<u>Steps:</u>
A = 13 × 6.5 - ((4 × 3×2)-2²)
A = 84.5 - (24 - 4)
A = 84.5 - 20
A = 64.5 in²
