A cell phone company charges a monthly fee of $50 for 300 minutes. Each addition minute costs $0.05. Determine if the function is linear or no linear and explain your reasoning.

Answers

Answer:

linear

Step-by-step explanation:

The graph would be linear since it's .05 every minute, which would mean that every minute it would cost .05 --> adding up minutes. The flat fee at the beginning is trying to trick you up, don't get fooled ;)

It is linear because the y intercept would start at 50 dollars on a graph and then be constant, making a line

Kevin is creating a target for a game that will be played at the school's carnival and needs to put red tape in the shape of an "x" as shown below. If the area of the square board is 25 square feet, how many feet of tape will he need?

Answers

Answer:Kevin need 14.14 feet of red tape  

Step-by-step explanation:

Given: (Figure Attached)

Area of Square  = 25 square feet

As we know

Area of square = length x width = a x a = 25

a * a = 25

a =  ±5 by taking square root both sides

It means a = 5 as the length can not be negative

Now we know the length of sides of square and as shown in figure we can break the figure in two triangles,

By using Pythagoras theorem on one triangle we will find the length of one line of x and then multiply the x with 2 to get the overall feet of tape.

 =  

=  

x = ± 7.07 It means x = 7.07

Now the total tape required is 2 * x = 2*7.07 = 14.14

Then, i did 0 x 2 and 2 x 0 to get 0, then i added and moved the decimal from 2.2 one time to make it 15.4. To check my work, i did 15.4 divided by 7 to get 2.2.

Answers

Answer:

We are given that:

variables x and y vary directly, this means that:

y = kx where k is the constant of proportionality

Now, we are also given that:

y = 45 at x = 40.

We will use these values and substitute in the above relation to get k as follows:

y = kx

45 = 40k

k = 45/40 = 9/8 = 1.125

Based on the above calculations, the equation that relates x and y is:

y = 1.125x
