Answer:
471.2 cm³ missing
Step-by-step explanation:
jars are cylinders
volume of cylinder = π * r² * h
h=10
r=5
v=785.4 cm³ of a full jar
r stays the same = 5
h = 4
v= 314.2 cm³ left in the jar
whats missing is the full-left
785.4-314.2=471.2 cm³ missing
We have been given that an account is opened with a balance of $3,000 and relative growth rate for a certain type of mutual fund is 15% per year.
In order to tackle this problem we have to find the value of mutual fund after 5 years. For our purpose we will use compound interest formula.
,where A= amount after t years, P= principal amount, r= interest rate (decimal) and t= number of years.
After substituting our given values in above formula we will get
Now we will solve for A
Therefore, after 5 years mutual fund is worth $6034.07.

Answer:
Step-by-step explanation:
Volumes of two spheres A and B = 648 cm³ and 1029 cm³
Things to remember:
1). Scale factor of two objects = [ and are the radii of two circles]
2). Area scale factor =
3). Volume scale factor =
Volume scale factor Or Volume ratio =
Therefore, scale factor =
≈ 6 : 7
Area scale factor Or area ratio =
=
≈ 36 : 49
Volume scale factor or Volume ratio =
=
≈ 216 : 343
The answer is down below following the order 6~9
