Answer:
55
Step-by-step explanation:
Original price = 50 and percent markup is 10%
The increase is the original price times the percent markup
increase = 50 * 10%
increase = 50*.10
= 5
The new price is the original price plus the increase
new price = 50 + 5
= 55

Answer:
7.8. 10 ^ 3 m / s
Step-by-step explanation:
The computation of the average speed in m/s is shown below:
The average speed equation is
= ΔS ÷ Δt;
As We know that
an entire revolution would be40,000 km
and a satellite takes 85 minutes to complete a revolution,
So,
ΔS = 40,000 km = 40,000,000 m
Δt = 85 min = 5 100 s
Now the average speed is
= 40 000 000 ÷ 5 ÷ 5 100
= 7843.14 m / s
= 7.8. 10 ^ 3 m / s
