In Jaunary your Verizon cell phone bill costs $12 for 80 minutes and in March your bill costs $9 for 60 minutes.

A) Determine whether the rate at which you are being charged for your phone bill is proportional to the amount of minutes being used. Explain.

Answers

Answer 1

Both rates are same when you divide them. 80/12= 6.6667 and 60/9= 6.667.

So, 6.6667 is the rate for each minute

Do 2 or more shapes with the same perimeter have to have the same area? Explain with examples. AND Do 2 or more shapes with the same area also have to have the same perimeter? Explain.

Answers

Yes. Take for example a square and an ellipsis with the same perimeter. The family of ellipses with the same perimeter can have any area between that of a circle to zero (if it is extremely “thin” i.e. if its eccentricity is large). The circle has the maximum area of any other shape with the same perimeter, so the square has the same area of one of the intermediate ellipses.

Miley and Cole ended up making the same number of biscuits for a bake sale at school, even though Miley made them in batches of 7 biscuits and Cole made them in batches of 11 biscuits. What is the smallest number of biscuits each must have baked?

Answers

Answer:

The smallest number is 77

Step-by-step explanation:

The LCM of 7 and 11 is 77 and I did LCM because it says "smallest number" which means I have to do LCM.

Answer:

77

Step-by-step explanation:

They each start at 0. Miley will be making them in groups of 7 and Cole 11.

Miley: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77.

Cole: 11, 22, 33, 44, 55, 66, 77.

The answer is 77.

Mark's bill for lunch at a restaurant is $14.50, and he wants to leave a 18% tip.
How much should he leave for the tip?

A. $2.18

B. $2.61

C. $11.60

D. $261.00

Answers

It’s B because you divide 18 percent from 14.50 dollars.
It would be B. Because 14.50 times .18 equals 2.61. Just put a decimal on it and move it to the right twice and multiply that by 14.50. If you need a better explanation you can message me! Hope this helps!:)
