A phone company offers two monthly plans. Plan A costs $13 plus an additional $0.14 for each minute of calls. Plan B costs $24 p

Semmy [17]

Answer:

m = number of minutes calls

Plan A : 30 + 0.15 m

Plan B: 16 + 0.20 m

For what amount of calling do the two plans cost the same?

30 + 0.15m = 16 + 0.20m

0.05m = 14

m = 280

280 minutes of calling, the two plans cost the same

What is the cost when the two plans cost the same?

Plan A: 30 + 0.15 m = 30 + 0.15 (280) = 72

Plan B: 16 + 0.20 m = 16 + 0.20 (280) = 72

It's cost $72 when the two plans cost the same

B.

A cant be, because the square root of 3 isn't a rational number/perfect square.
C can't be because the square root of 5 isn't a rational number/perfect square.
D cant be because pi isn't a rational number.

However, B can be because the square root of 25 is a rational number/perfect square. Which is 5

A cone has a radius of r units and a height of h units. a cylinder has a ridius of 2r units and has the same volume as the cone.

algol [13]

Volume of a cone is calculated as:

$V_{cone}= \frac{1}{3} \pi r^{2} h
$

Volume of the cylinder is calculated as:

$V_{cylinder}= \pi R^{2}H$

The radius of cylinder is twice the radius of cone. So R=2r. The two volumes are given to be equal, so we can write:

$\frac{1}{3} \pi r^{2} h= \pi R^{2} H \\ \\ 
 \frac{1}{3} r^{2} h= (2r)^{2} H \\ \\ 
 \frac{1}{3} r^{2} h= 4r^{2} H \\ \\ 
 \frac{1}{3} h= 4H \\ \\ 
H= \frac{1}{12}h$

Thus, the height of the cylinder will be h/12
