You divide 5 and 16 to get the answer: 0.3125.
If the number of downloads of the standard version is x, and the high quality is x, 2.1*x+4.1*y=2761 (not 1010 due to that this is multiplied by 2.1 and 4.1, therefore representing the total amount of megabytes) In addition, there are 1010 total downloads, and it's either 2.1 MB or 4.1 MB, so x+y=1010.
We have
2.1x+4.1y=2761
x+y=1010
Multiplying the second equation by -2.1 and adding it to the first equation, we get 2y=2761-1010*2.1=640 and by dividing both sides by 2 we get y=320 downloads of the high quality version
Answer: 64 mph
We can see that after every hour, the car has traveled 64 miles. So the speed rate is 64 miles per hour.
Answer:
5/6
Step-by-step explanation:
The sides numbered 1,2,5 are green and 2,4,6 are even
We cannot count the 2 twice, so there are 5 unique possibilities of getting either a green or an even
There are 6 total possibilities when rolling the die 1,2,3,4,5,6
P (green or even) = green or even/ total
= 5/6
Let u = 5x+1. Then du = 5·dx, and your integral is
