The distance between earth and Saturn is 1.2 billion km(746 miles) so if 28,000= 1 hr then 1,200,000,000÷28,000 is 42857.14286 or 42,857.14 (1,785.71 days. or 4.89 years)
Answer: $58.33 (Rounded bc it ends up in becoming a decimal)
Explanation: Let's make an equation for this problem. We know that if she works 3 hours for $25, 3*2=6 with 1 hour leftover. We can substitute those 6 hours for 2 sets of the 3 hours, giving us $50 so far. For the last hour, we have to divide 25 by 3 because it's only 1 hour instead of 3, meaning she'll get paid a third of the original pay rate. 25/3 equals 8.33333333334, so we'll just round that to 8.33, since it's cash. 50+8.33=$58.33. So, you'd earn 58 dollars and 33 cents for working for 7 hours.
Step-by-step explanation:
<h2>1. kinetic energy = 1/2 mass× velocity²</h2>
mass= 5.2. velocity =2.4
thus, 1/2 × 5.2×2.4×2.4
<h3>= 14.97joule</h3>
<h2>2. potential energy = mass× acceleration × height </h2>
mass=5.2. height=5.8 g=9.8
=5.2×5.8×9.8
<h3>= 295.5 joule</h3>
<h2>3. mechanical energy = potential energy + kinetic energy </h2>
= 295.5+14.97
<h3>=310.47 joule</h3>
hope it helps :)
Answer:
The estimate is less than the actual length of the CD.
Step-by-step explanation:
Consider the provided information.
Maurice's new CD has 12 songs. Each song lasts between 3 and 4 minutes.
That means the minimum length of the CD should be: 12×3=36 minutes.
The maximum length of the CD should be: 12×4=48 minutes
He estimates that the whole CD is about 30 minutes long.
30 minutes is less than 36 minutes.
That means, the estimate is less than the actual length of the CD.
Hence, the correct statement is: The estimate is less than the actual length of the CD.
The next answer to the next step is simplify y
