your cell phone carrier charges $0.18 for each extra minute over your limit.if the total shows that you owe $3.24 for extra minu
arlik [135]
If you have
\dfrac{1 \ min}{0.18 \ dollars}
as your cost,
and you paid
3.24 \ dollars,
then 
(\dfrac{1 \ min}{0.18 \ dollars})(3.24 \ dollars)=18 \ min.

Thankfully, most cellphone companies don't charge for minutes anymore!

How many cubic inches of material do you need to make a solid rubber ball with diameter<br> of 3
Lera25 [3.4K]

Answer:

Step-by-step explanation:

What we're looking for here is the volume of this ball, which is the volume of a sphere:

V=\frac{4}{3}\pi  r^3

If our diameter is 3, then the radius is 1.5:

V=\frac{4}{3}\pi  (1.5)^3

In terms of π, the solution is

4.5\pi which can also be expressed as \frac{9\pi }{2}

Or if you have to multiply in the pi, the solution is

V = 14.14 cubic inches

I need help on solving.
bulgar [2K]

Answer:

x =  - 1 \\  - 2 + 0.4y = 0.4 \\ 0.4y = 0.4 + 2 = 2.4 \\ y = 2.4  \div 0.4 = 6 \\ y = 1 \\ 2x + 0.4 = 0.4 \\ 2x = 0.4 - 0.4 = 0 \\  x = 0

The first two terms in a geometric series are 20, 22. To two decimal places, the sum of the first k terms of the series is 271.5
Triss [41]

Answer:

k=9

Step-by-step explanation:

First find r=22/20=1.1

The sum of the first k terms formula is a1•(1-r^k)/(1-r)

a1=20 and the sum is 271.59

Now plug in these values in the formula and find k.

271.59=20(1-1.1^k)/(1-1.1)

When you simplify this equation, you will get k=ln(2.358)/ln(1.1)

k=9

Find the lengths, if needed round to the nearest tenth
Elis [28]

Answer:

Step-by-step explanation:

Triangle ABC is a right angle triangle that is made up of 2 right angle triangle.

To determine y, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

15² = y² + 12²

225 = y² + 144

y² = 225 - 144 = 81

y = √81 = 9

To determine z,

20² = z² + 12²

400 = z² + 144

z² = 400 - 144 = 256

z = √256 = 16
