We want to find the speed of the hyper loop if it takes 11 minutes from Dubai to Abu Dhabi. We will find that the speed is 761.75 km/h
<h3>
Working with speeds.</h3>
Remember the relation:
speed = distance/time.
Here we know that the time is 11 minutes (the time in which the distance is traveled) and the distance will be the distance from Dubai to Abu Dhabi, which we can find online.
The distance is 139.4 km
Now, we know that:
1 hour = 60 minutes.
Using this we can write the time in hours.
11 min = (11 min/60min) hours = 0.183 hours
Now we can just compute the speed:
S = (139.4 km)/(0.183 h) = 761.75 km/h

Answer:
{x:x>6}
Step-by-step explanation:
x-3>3
Add 3 to each side
x-3+3>3+3
x>6
{x:x>6}
Answer:
20
Step-by-step explanation:
Since that is a true equation, you can substitute 7x - 7 y for 4 and simplify.
5(7x - 7y)
5(4)
20
Answer:
Step-by-step explanation:
PV = $2500
r = 6%
Compounded semi annually for ten years => number of periods: 10*2 = 20
a. the balance of account at end of peroid (FV)
FV = PV = 2500 = 8017.8386
b. How much interest is earned; FV - PV = 8017.8386 - 2500 = 5517.8686
c. what is effective rate of interest :
0.45 liters water was evaporated
Step-by-step explanation:
Given
The water in flask = 1.5 litres
Water int he flask after boiling = 70%
If the water in flask is 70%, then
100-70 = 30% water has been evaporated.
So,
Evaporated water in liters:
Hence,
0.45 liters water was evaporated
