Answer:

$59

Step-by-step explanation:

So, there is 500 minutes for $39.

Each additional minute costs 40 cents.

There is 50 extra minutes.

50 x 40 = 2000, so 20 extra dollars. Add that on to $39.

$39 + $20 = $59

The total is $59 before tax is added.

How many triangles can be formed with segments measuring 4. 72 yd, 6. 31 yd, and 1. 67 yd? none one more than one.
scoray [572]

The triangle inequality theorem is not followed,  no triangle can be formed.

<h3>Triangles</h3>

In Geometry, a triangle is a three-sided polygon that consists of three edges and three vertices.

The triangle inequality theorem describes the relationship between the three sides of a triangle.

According to the triangle inequality theorem, the sum of any two sides must be greater or equal than the length of the third side.

Here, the sides are 4.72 yds, 6.31 yds, and 1.67 yds.

4.72 + 6.31 = 11.02  >  1.67  (theorem followed)

4.72 + 1.67 = 6.39  > 6.31    (theorem followed)

6.31 + 1.67 = 7.98 > 4.72 (theorem not followed)

Since the triangle inequality theorem is not followed,

Hence, no triangle can be formed.

PLEASE HELP I HAVE NO IDEA WHAT IM DOING!!!

Answer: 28.26


Step-by-step explanation:

What your looking for is called the annulus (or the difference of two concentric circles). You can find the annulus by subtracting the area of the inner circle from the area of the outer circle. Volume of a circle= πr²

You are given the diameter in these problems, so you need radius.

For the first circle (8 in one) :

8/2=4    r=4

A=3.14(4)²

A=50.24

For the second one (10 in one) :

10/2=5   r=5

A=3.14(5)²

A=78.5

To find the measure of the annulus, you subtract those numbers, getting 28.26
