Answers:
Question 19: 177 bpm
Question 20: 95˚F

Explanations:
Question 19:
You had the formula set up properly like this:
$R = \frac{885 \sqrt{25} }{25} = \frac{885(5)}{25} = \frac{4425}{25}$
This is where you went wrong - I don't know exactly what you did, but your division of 4425 ÷ 25 is wrong. You should have ended up with 177 which is the correct answer.
Question 20:
You had the formula set up correctly again, and merely used the wrong sign when adding 32.
$F = \frac{9(35)}{5} + 32 = \frac{315}{5} + 32$
This is where you went wrong. You subtracted 32 from 63 when you should have added it. (See red circle on your subtraction.)
63 + 32 = 95˚F

mike drove to a frineds house at the rage of 40 mph. he returned hoke by the dsne route at 45 mph the driving time for the round

wolverine [178]

Let the distance be x miles

Time = Distance / speed

Time taken by Mike to go to his friend's house = x / 40 hours

Time taken by him to return = x / 45 hours

Total time = x / 40 + x / 45 = 4 hours

= 9x + 8x = 1440 miles

17x = 1440

= x = 1440 ÷ 7

= x = 84.706

Time taken to return home = 84.706 /45= 1.882 hours .

Therefore , Mike took 1.882 hours to reach home .
