Answer:
6 mph
Step-by-step explanation:
Use formula

where
D = distance
r = rate
t = time
In your case,
D = 12 mi
<u>Dina:</u>
D = 12 mi
r = 8 mph
t = ?
So,

<u>Masha:</u>
D = 12 - 3 = 8 mi
r = ?
t = 1.5 hours
Then

If you would like to know how much money you must save for an emergency fund of 6 months, you can calculate this using the following steps:
36% of $3,076.45 = 36% * 3,076.45 = 36/100 * 3,076.45 = $1,107.522
6 months * $1,107.522 = 6 * 1,107.522 = $6,645.132
The correct result would be $6,645.132.
86 and 94 :) supplementary angles add up to 180 degrees while complementary add up to 90 degrees
The Second gear will complete 75 revolutions.
Hope this helps. I tried using my past knowledge.
