Answer:
He can make 12 batches of pancake
Step-by-step explanation:
Total amount of milk = 9 cups
One batch of pancake uses 3/4 cup of milk.
y batch of pancake uses 9 cup of milk.
Therefore ( y ) x (3/4) = 9

Answer:
C. 48 cubic units
If you fill up the whole prism and it takes exactly 48 cubes then you did it correctly.
Step-by-step explanation:
To find the volume of a rectangular prism you have multiply the base by the height by the width.
So the volume is b*h*w = 8*2*3 = 48
C. 48 cubic units
Since 1 cube takes 1 unit that means it takes 48 cubes to fill up the whole thing.
If you fill up the whole prism and it takes exactly 48 cubes then you did it correctly.
This is an exponential decay function, or it can also be viewed as a geometric sequence, either way, it can be expressed in this circumstance as:
f=ir^t, f=final amount, i=initial amount, r=common ratio or rate, t=times ratio is applied or time.
In this case i=2000 and r=(100-7)/100=0.93 so
f=2000(0.93^t)
We are asked to find when f=600 so:
600=2000(0.93^t) divide both sides by 2000
0.3=0.93^t, take the natural log of both sides
ln0.3=t*ln0.93 divide both sides by ln0.93
(ln0.3)/(ln0.93)=t
t≈16.59
So in about 16.5 years she will own only 600 square miles. (round as appropriate for your answer)
