What is a rational number with a denominator of 7 that is between 7–√ and 8–√. Write your answer as an improper fraction.(1 point)
To find the rational number between 7–√ and 8–√, we need to add the two numbers and divide by 2.
(7–√ + 8–√)/2 = (15–2√)/2 = 15/2 – √2
Therefore, the rational number with a denominator of 7 that is between 7–√ and 8–√ is 15/2 – √2.

Low Temperatures in Milwaukee, Wisconsin (°F)
Monday Tuesday Wednesday Thursday Friday Saturday Sunday
28 36 39 30 22 18 35
What is the range of temperatures over the seven days?
(1 point)
°F
To find the range of temperatures, we need to subtract the lowest temperature from the highest temperature.
Highest temperature: 39°F
Lowest temperature: 18°F
Range = Highest temperature - Lowest temperature
Range = 39°F - 18°F
Range = 21°F
Therefore, the range of temperatures over the seven days is 21°F.
