Answer:
Mme Q spent more time answering emails from students by 10 minutes
Step-by-step explanation:
Here we have
Time spent by Mme Q in answering mails on Friday given by
5/6 Hour = 50 minutes and
7/12 Hour = 35 minutes
Total time spent on Friday = 85 Minutes or
5/6 + 7/12 = 17/12 Hours
Time spent by Mme F in answering mails on Friday given by
1/2 Hour = 30 minutes and
3/4 Hour = 45 minutes
Total time spent on Friday by Mme F = 75 Minutes or
1/2 + 3/4 = 5/4 Hours
Therefore, Mme Q spent more time answering emails from students by 85 - 75 = 10 minutes.
Answer:
Well as a fraction it would be 2/5, if you would like it as a number you divide 300 by 3/5 and use the leftovers.
Answer:
Since the question requires you to give the answer in terms of steps/minute, the first step would be to convert hours to minutes: 12.5 hours = 750 minutes. Next, if he took 775 steps in 750 minutes, how many would he take in 1 minute? This requires you to set up the question as a proportion: (775 steps/ 750 minutes) = (x steps/1 minute)
Step-by-step explanation:
Answer: Mckenzie is correct
<em>I had to reformat this section with the way it was typed, please let me know if I did anything wrong.</em>
<u>Mckenzie's Work</u>
a² + b² = c²
25 + 169 = c²
194 = c²
Square root 194 equals square root c squared.
c ≈ 13.93
<u>Cara's Work</u>
a² + b² = c²
25 + b² = 169
b² = 144
Square root b squared equals square root 144.
b ≈ 12
[] Right away we can tell that <u>Cara is not correct.</u>
-> Cara solves for b. We already have a b value, we need to solve for "c" in the equation.
[] Now let's look at Mckenzie.
-> Mckenzie does solve for the right variable, so let's see if she did it correctly.
-> First, she sets is up using a² + b² = c² since this is a right triangle. Next, she squares 5 to 25 and 13 to 169. Both correct.
-> Now they are added together. 25 + 169 do equal 194 so this looks correct.
-> Last, we square both sides. 
≈ 13.928388 which rounds to 13.93, so it looks like <u>Mckenzie is correct</u>.
Have a nice day!
