ValentinkaMS [17]

Answer:

<u>The French restaurant did not use cream this year, due to a menu update.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount of cream used by a French restaurant last year = 92.870 ounces

Amount of cream used by the French restaurant this year = 100% less

2.  How much cream did the restaurant use this year?

The answer is zero and we calculated it this way:

92,870 - 100% (92,870) = 92,870 - 92,870 * 1 = 92,870 - 92,870 = 0

<u>The French restaurant did not use cream this year, due to a menu update.</u>

Alan's go kart travels 1750 feet per minute and Barry's go kart travels 21 miles per hour whose go kart travels faster round you
krok68 [10]

Answer:

Barry's kart is faster as he goes 21 Mph while Alan only goes 19.89 Mph.

Step-by-step explanation:

First to get this answer we need to convert feet per minute to miles per hour. So we multiple 1750 feet per minute by 60 to get a hour. This gets up 105000 total feet in a hour. Now we need to divide this by 5280, which is how long a mile is, to get 19.89 miles which is how many miles he travels in a hour making him travel 19.89 mph which is less than 21 making Barry faster.
