Answer: Time taken =1.25 x 10^1 hours 0r 4.5 x 10^4s
Step-by-step explanation:
Step 1
how long will it take the rocket to make the trip from Earth to the satellite = Time taken for the rocket to make the trip from Earth to the satellite
Speed = Distance / Time ,
Time = Distance / speed
Step 2-- solving
Time = Distance / speed
Time=2.5×10^5 miles/2.0×10^4 miles per hour
=12.5 hours = 1.25 x 10^1 hours
or 1.25 x 10^1 hours x 3600 = 45,000 seconds = 4.5 x 10^4s
Answer:
Step-by-step explanation:
<u>Given information</u>
Paid = $15.00 / hour
Paid (Last 4 hours) = Doubled the usual pay rate
Total hour = 12 hours
<u>Given expression</u>
Wage = Pay rate × hours except for the last 4 hours + Double Pay rate × 4 hours
<u>Substitute values into the expression</u>
Wage = (15) × (12 - 4) + (15 × 2) × (4)
<u />
<u>Simplify values in the parenthesis</u>
Wage = 15 × 8 + 30 × 4
<u>Simplify by multiplication</u>
Wage = 120 + 120
<u>Simplify by addition</u>

Answers:
Biggest = 100 inches
Smallest = 31 inches
=======================================================
Work Shown:
Replace d with 132 to get,
Tmax = 3d/4 + 1
Tmax = 3*132/4 + 1
Tmax = 396/4 + 1
Tmax = 99 + 1
Tmax = 100
The biggest size they should buy is a 100 inch tv.
Do the same for the minimum size equation.
Tmin = d/4 - 2
Tmin = 132/4 - 2
Tmin = 33 - 2
Tmin = 31
The smallest tv they should buy is a 31 inch tv.
