Answer:

Step-by-step explanation:

perp. -1/2

y + 3 = -1/2(x - 3)

y + 6/2 = -1/2x + 3/2

y = -1/2x - 3/2

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $13 monthly fee

Tpy6a [65]

Answer:

With 250 minutes of calls the cost of the two plans is the same

Step-by-step explanation:

We must write an equation to represent the cost of each call plan.

<u>For the first plan</u>

Monthly fee

$ 13

Cost per minute

$ 0.17

If we call x the number of call minutes then the equation representing the cost c for this plan is:

$c = 13 + 0.17x$

<u>For the second plan</u>

monthly fee

$ 23

Cost per minute

$ 0.13

If we call x the number of call minutes then the equation representing the cost c for this plan is:

$c = 23 + 0.13x$

To know when the cost of both plans are equal, we equate the two equations and solve for x.

$13 + 0.17x = 23 + 0.13x\\\\0.17x -0.13x = 23-13\\\\0.04x = 10$

$x = \frac{10}{0.04}$

$x = 250\ minutes$

With 250 minutes of calls the cost of the two plans is the same: $55.5

What 3 numbers have 3 factors?.

Softa [21]

We are aware that the numbers 4, 9, 25 and 49 are among those between 1 and 100 that have precisely three elements.

Given,

What number has three components?

In fact, the squares of primes are the only positive integers with precisely three factors. For instance, 1, 3, and 9 are the factors of 9, and 1, 7, and 49 are the factors of 49.

If a given number, such as x2, is perfect square, and its square root is prime, it must have precisely three different factors.

Here,

We are aware that the numbers 4, 9, 25 and 49 are among those between 1 and 100 that have precisely three elements.

1, 2, and 4 are the four factors. 1, 3, and 9 are the factors of 9.

I have a circular piece of fabric I am going to make a tablecloth. The radius of the fabric is 2 meters. What is the area of the

Bond [772]

Answer:

$4\pi$

or

12.57

Step-by-step explanation:

I have a <u>circular</u> piece of fabric I am going to make a tablecloth. The <u>radius</u> of the fabric <u>is 2 meters</u>. What is the <u>area</u> of the tablecloth I can make

Essentially, you are attempting to find the area of a circle with a radius of 2 meters.

The formula for an area of a circle is $\pi r^2$ , or pi times radius squared.

Plugging in 2 meters as your radius, that gets your answer to be $4\pi$ , or 12.57 in decimal.
