An equilateral triangle is a triangle which has sides of equal length. Therefore the perimeter would be the sum of these sides and will reduce to three times the side length. We calculate x as follows:

P = 63 = 3(x-10)
21 = x-10
x = 31 units

Tanisha and Rebecca are signing up for a new cell phone plan to only charge for the number of minutes and everything else includ

xeze [42]

Answer:

see the explanation in the procedure

Step-by-step explanation:

The complete question is

Tanisha and Rebecca are signing up for the new cellphone plans that only charge for the number of minutes and everything else is included in a monthly fee. Their plans are as follows:

Tanisha s Plan: $0.15 per minute used talking and a $25 monthly fee

Rebecca s Plan: $0.10 per minute used talking and a $18.50 monthly fee

After how many minutes will the two plans charge the same amount?

Let

x ----> the number of minutes

y ---> the total charge in dollars

we know that

Tanisha s Plan

$y=0.15x+25$ -----> equation A

Rebecca s Plan

$y=0.10x+18.50$ -----> equation B

To find out after how many minutes will the two plans charge the same amount, equate equation A and equation B

$0.15x+25=0.10x+18.50$

solve for x

$0.15x-0.10x=18.50-25$

$0.05x=-6.5$

$x=-130\ min$

therefore

They will never pay the same amount , because the time cannot be a negative number.

Rebecca s Plan is better than Tanisha s Plan because it has smaller fee and less cost per minute

Find all possible values of the expression 1/y if: .125

34kurt

Answer:

The possible values for 1/y of the expression 0.125 < y < 0.25 are in the range

4 < 1/y < 8

Step-by-step explanation:

The given information are;

The range of values of y are 0.125 < y < 0.25, therefore, we have;

The boundaries of the function, y are 0.125 and 0.25

The inverse of the boundaries of the function, y are 1/0.125 = 8 and 1/0.24 = 4

Therefore;

The limits of the inverse of the function y are ;

The inequality that represents 1/y is therefore;

1/0.25 < 1/y < 1/0.125 or 4 < 1/y < 8

The possible values of 1/y for the expression 0.125 < y < 0.25 are therefore;

4 < 1/y < 8.
