What is the length of a phone call that would cost the same no matter what company is used?Company A - 0.35cents plus 0.3cents per minute
Company B - 0.45cents plus 0.2cents per minute

Answers

Answer 1
Answer:

Answer: The length of phone call is 1 minute that would cost the same for both the companies.

Step-by-step explanation:

Since we have given that

Company A - 0.35cents plus 0.3cents per minute

Company B - 0.45cents plus 0.2cents per minute

Let the number of minute be x.

So, our equation for company A would be

0.35+0.3x

our equation for company B would be

0.45+0.2x

According to question, length of phone call that would cost the same.

so, our equation becomes

0.35+0.3x=0.45+0.2x\n\n0.3x-0.2x=0.45-0.35\n\n0.1x=0.10\n\nx=(0.10)/(0.1)\n\nx=1

Hence, the length of phone call is 1 minute that would cost the same for both the companies.

8:4 6:4 8:2 6:3 biggest ratio

Answers

Easy, make the ratios as a decimal. 8:4=2, 6:4=1.5, 8:2=4, and 6:3=2. Now, we have 2, 1.5, and 4, and 2. We can eliminate 8:4 and 6:3 since they are the same ratios, 1.5 equals 1.50, 4=4. Ask your self. Is 1.50 greater than 4? Well your answer is no. 4 is greater than 1.50. So, the biggest ratio is 8:2
8:2 is the biggest ratio, because if you reduce each ratio to the smallest ratio 4:1 is the biggest. 8:4 = 2:1... 6:4 = 3:2...  8:2 = 4:1... 6:3= 2:1...
