Part C:

y = total cost

M = minutes


You can talk on the phone only 100 minutes per month

Company A:

y = 0.04M + 5

y = 0.04(100) + 5

y = 4 + 5

y = 9             $9 per month


Company B:

y = 0.10M + 2

y = 0.10(100) + 2

y = 10 + 2

y = 12          $12 per month


Company A offers the best deal because at Company A you have to pay $9 for 100 minutes per month, and at Company B you have to pay $12 for 100 minutes per month, so you have to pay $3 less.


Part D:

1.) With a budget of $30, Company A would allow me to talk longer on the phone. I know this because for Company A, you pay $3 less per month for the same amount of minutes as Company B. This means that I will save more money with Company A, and I can buy more minutes. (something like this)

1.Un cazador ubicado en la coordenada C (-5,8) y un venado ubicado en las coordenadas V (7,1). Escala 1 unidad = 10 ma)Determina
True [87]

The distance between the coordinates in meters is 138.92m

Using the distance formula to calculate the distance between the coordinates as shown:

D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\

Given the coordinate points C(-5, 8) and V (7, 1)

Substitute the given coordinates into the formula

D = \sqrt{(7+5)^2+(1-8)^2} \\D = \sqrt{(12)^2+(-7)^2} \\D = \sqrt{144+49} \\D = \sqrt{193} \\D=13.892 units

Given that 1 unit = 10metres

D = 13.892 * 10

D = 138.92 meters

Hence the distance between the coordinates in meters is 138.92m

How many minutes does it take the duck to fly 1 kilometer?
andreyandreev [35.5K]

Answer:

0.25 minutes

Step-by-step explanation:

It will take 1/12 the time for the duck to fly 1/12 the distance. Therefore, it will take 3 * 1/12 minutes which is 0.25 (1/4 in fraction form).

Hope this helps :)

What does a supplementary angle look like
Keith_Richards [23]

Answer:

It has no special appearance.

Step-by-step explanation:

Any angle of measure 180° or less is supplementary to some angle. A supplementary angle is one that is the difference between 180° and the angle you have. That is, two supplementary angles total 180°.

__

Supplementary angles are readily identifiable in a number of geometries. Adjacent angles of a parallelogram are supplementary; linear angles are supplementary. Same-side interior angles where a transversal crosses parallel lines are supplementary.
