Answer:
67.5
Step-by-step explanation:
this gives you the basis of the problem, 2 pages every 3 minutes, so that means that you have to divide 45 by 2, this will give you 22.5
then you multiply by 3 because 22.5 is how many sets of 2 Ella has to read, and if we remember every set of 2 pages takes 3 minutes, so 22.5 times 3 is 67.5, but if you want the answer in time it would be 67 minutes and 30 seconds because a minute is 60 seconds and half of that is 30
Out of the 6 answers you have, the correct answers are 1, 3, 4, and 6.
Answer:
The father is 40 and the son is 4.
Step-by-step explanation:
40 + 5 = 45.
4 +5=9.
45 divided by 5 = 9
100/25 = 4
4*3 = 12
The answer is 12%
Hope this helps! :)
Answer:
Step-by-step explanation:


Volume = 
find partial derivatives using product rule

i.e.
Using maximum for partial derivatives, we equate first partial derivative to 0.
y=0 or x+y =6
x=0 or x+4y =12
Simplify to get y =2, x = 4
thus critical points are (4,2) (6,0) (0,3)
Of these D the II derivative test gives
D<0 only for (4,2)
Hence maximum volume is when x=4, y=2, z= 4/3
Max volume is = 4(2)(4/3) = 32/3
