A 2.2 GB game is being downloaded onto your laptop. When you have downloaded half a gigabyte, you notice that your computer has

zzz [12365]

Answer:

$0.01m +\frac{1}{2} \geq 2.2$

Step-by-step explanation:

Let m denote the number of minutes required to download the entire game.

The computer downloads at a speed of 0.01 GB per minute, and since half a gigabyte has already been downloaded, we can express this as 0.01*m + 0.5 equaling 2.2, as the game's total size is 2.2 GB.

We will determine the minimum number of minutes necessary to completely download the game.

$0.01m +\frac{1}{2} \geq 2.2$

$0.01m +0.5\geq 2.2$

$0.01m \geq 2.2-0.5$

$0.01m \geq 1.7$

$m\geq \frac{1.5}{0.01}$

Thus, $0.01m +\frac{1}{2} \geq 2.2$ represents our sought inequality.

The formula for distance is d=rt. If Eddie covers 72 meters in 12 seconds, his rate is 6 meters per second.

d=rt
72=r·12
r=6
d=6t

The answer is c.

A flower vendor sells roses for 50 cents each. How much does she pay per flower is she makes $6.00 on every twenty dollars worth

tester [12383]

A single rose sells for 50 cents, so buying two will cost $1 (50 cents multiplied by 2).

With 2 roses per dollar, spending $20 allows for the purchase of 40 roses.

They make $6 profit on $20 sales, which means they spend $14 on the 40 roses ($20 minus $6).

Dividing $14 by 40 roses gives a cost of $0.35 per rose.

Therefore, the vendor pays 35 cents for each rose.
