A. 9 3/4 hours
b. i’m not too sure :)
= 0.10606
Step-by-step explanation:
Since we have only one digit in the numerator and the denominator has 2 digits, we have to 0 along with 7, so that it becomes 70, 1 time 66 is 66, 70 - 66 = 4 is the remainder, so the quotient is 0.1, then along with 4 we have to add one 0 , so it becomes 40 which is lesser than 66 so one more 0 is added and then it becomes 400, 6 times 66 is 396, 400 - 396 = 4 again the process going on. The quotient is 0.10606...
C. 2g-19.5=40 I think i'm right
The answer is 90 because 360/4 (since it is a quadrilateral) is 90 degrees
Here is the formula: b•h/2
