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
J=justin
marcella=m
aimee=a
j is 2 older than 1/3 of m
'of' means multiply
j=2+1/3m
a is 4 younger than 2 times j
a=-4+2j
represent justin's age?
dunno
ok so I can solve if I know m=63
j=2+1/3m
j=2+1/3(63)
j=2+21
j=23
subsitute
a=-4+2j
a=-4+2(23)
a=-4+46
a=42
justin is 23 and aimee is 42 if marcella is 63
For number 7 it’s basically 4x3 and 4x6 and for number 8 it’s 4x7 and 2x7
For number 9 it’s 5x3, 5x6, 5x2
Answer:
-128
Step-by-step explanation:
(-2)^2 * (-2)^5 <---
First, add the exponents
(-2)^7<----
If you evaluate this you will get
