Yanka [14]

Answer:

Nate should leave a tip of $6.30.

Step-by-step explanation:

Since the total bill was $52.43, and Nate wants to leave a 12% tip, you would have to find out what 12% of 52.43 is. To find this out you would multiply 52.43 by 12%. This is 6.2916. So, to leave the waiter a 12% tip, Nate would leave about $6.30.

Ivanshal [37]

Answer:

The exact number would be 26.66666667 but it would be 26.

Step-by-step explanation:

Usually when dealing with decimals anything 5 and up would be rounded up but since we are dealing with money we don't round up. Since his friends lunch cost $3 every lunch the most he will be able to buy is 26. He will have about $2.5 left over which he cannot buy a lunch with so thats why you dont round up.

A cheetah runs 300 feet in 2.29 seconds. How would you convert the cheetahs speed to miles per hour?
xeze [42]

plain and short, an hour has 60 minutes, and a minute has 60 seconds, therefore an hour has 60*60 or 3600 seconds, and we can express that  rate as hr/3600s or the other way around 3600s/hr, depending on which version we need.

a mile has 5280 feet, again, we can use that rate as mile/5280ft or 5280ft/mile, as needed.


\bf \cfrac{300 ft}{2.29 s}\cdot \cfrac{3600 s}{hr}\cdot \cfrac{mi}{5280 ft}~\hspace{10em}\stackrel{\textit{using minutes as well}}{\cfrac{300 ft}{2.29 s}\cdot \cfrac{60 min}{hr}\cdot \cfrac{60 s}{min}\cdot \cfrac{mi}{5280 ft}}
