Answer:

11) x = 9

12) x = 9

Step-by-step explanation:

11) Corresponding segments are proportional, so ...

x/6 = 12/8

x = 6(12)/8 . . . multiply by 6

x = 9

12) Similar triangle relationships show you the geometric mean relationship that applies in this case.

long side/short side = x/3 = 27/x

x² = 3·27 . . . . . . cross multiply

x = √(3·27) . . . . geometric mean relationship

x = 9

Find the fourth term of a geometric sequence if a=6 and r=2. Use the formula an=ar^n-1

Vikentia [17]

Answer:

Step-by-step explanation:

here, we are using an = ar^n-1

so, we have to find a4= ar^4-1 = ar^3

now, putting the given values in the equation,

a4= (6)(2)^3 = 6(8) = 48

therefore, the 4th term is 48.

I have done this question previously on Gauthmath app, you can check that app out, really cool app.

All the best with your exam.

A conical paper cup has dimensions as shown in the diagram. How much water can the cup hold when full?

dusya [7]

By definition, the volume of a cone is given by:
 $V = (1/3)*( \pi)*(r^2)*(h)
$
 Where,
r: radius of the circular base of the cone.
h: cone height
The cone radius is given by:
 $r = d / 2 
$
 Where,
d: diameter of the circular base.
Substituting values we have:
 $r = 6/2 

r = 3 cm$ 
Then, the volume will be:
 $V = (1/3) * (3.14) * (3 ^ 2) * (10) 

V = 94.2 cm ^ 3$ 
Answer:
The volume of the cone is given by:
 $V = 94.2 cm ^ 3$
