Answer:
A (Elise needs 7 quarts of ice cream)
Step-by-step explanation:
Okay so we know that Elise is serving 42 people, since she's making 42 chocolate ice cream sundaes.
Since it takes 3 quarts to serve 18 people, we know that the amount of people divided by 6 will equal the quarts.
So 42 people divided by 6 equals 7 quarts.
i hope this helps !!
Answer:
Step-by-step explanation:
y=ar^x
(ar^5)/(ar^3)=72/432
r^2=1/6
Since r^2 < 1
This is exponential decay.
The comparison may be done by the dimensional analysis and the proper conversion factor. That is,
(7.8 x 10^5 m/h) x (1 km / 1000 m) x (24 h / 1 day) = 18720 km / day
The scientific notation of the answer is 1.872 x 10^4 km/day. Thus, the answer is letter D.
After 20% reduction the price is $48 which means $48 is only 80% of the original price...so let x= original price
<span>48=.8x </span>
<span>60=x </span>
<span>it was $60
