Answer:
768 inches^2 (squared)
Step-by-step explanation:
Volume of a rectangular prism is Length x Width x Height
16 x 12 x 4
= 768 inches^2
Answer:
102
Step-by-step explanation:
You have to substitute x and y. Since x = 3 and y = 4, you would write the equation as 6(3) + 21(4). Multiply that, and you get 18 + 84. Add that together, and you get the answer 102.
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
