Answer:
90
Step-by-step explanation:
<u>Given:</u>
The volume of a cylinder =15
Height of cone = Height of either cylinder
Radius of cone=Radius of either cylinder
<u>Formula:</u>
Volume of a cone =
Volume of a cylinder =
<u>To find: </u>Combined volume of both cylinders.
The volume of a cylinder =15
=15
=15 * 3
=45
[As
Height of cone = Height of either cylinder
Radius of cone=Radius of either cylinder<u>]</u>
=45 is the volume of one cylinder.
Combined volume of cylinder = 2* Volume of cylinder = 2*45 =90

Answer:
Total number of quarters=10
Total number of nickels=19
Step-by-step explanation:
The expression for the total value of money you have is;
Quarters have a value of= $0.25
Nickels have a value of= $0.05
Total value=(value of quarters×number of quarters)+(value of nickels×number of nickels)
where;
Total value=$3.45
Value of a quarter=$0.25
number of quarters=x
Value of a nickel=0.05
number of nickels=y, but y=x+9
replacing;
3.45=(0.25×x)+0.05(x+9)
3.45=0.25 x+0.05 x+0.45
3.45=0.3 x+0.45
0.3 x=3.45-0.45
0.3 x=3
x=3/0.3
x=10
y=x+9=10+9=19
Total number of quarters=10
Total number of nickels=19
