Answer:
a
Step-by-step explanation:
Well in the first you buy 5P+2B+3L
but then you buy 3P +1B+2L
and you add then up
By "-21x + 9 + y equals -24x + 8" I'm assuming you meant
"y = -21x + 9 AND y equals -24x + 8." Using " + " to indicate "and" could be confusing.
We then have the system of linear equations
y = -21x + 9
y = -24x + 8
The function with the greater slope is the 2nd: y = -24x + 8 (with the understanding that we're focusing on the magnitude of the slopes). Thus, it is this function that changes more quickly.
It is 72 1/10. This is because 72 is a whole number and point one would be tenths.
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
