I believe its 45 because a right angle equals 90 degrees and if you multiply 45 and 2, it'll give you a right angle(90 degrees)
38.5 / 1.25 = 30.8 or 77/2 divide by 5/4 = 154/5 = 30.8
so, the unit rate is 30.8
Easy do 12 times 16 divided by two = 96
answer=96
C, both speed and It’s velocity
The answer is 84 7/12
You would convert the mixed fractions to improper fractions then multiply the numerators and denominators. Then you convert your answer back into a mixed fraction.
7 1/4 is equal to 29/4
11 2/3 is equal to 35/3
29/4 • 35/3
So 29 • 35 = 1015 and 4 • 3 = 12
Now you have the improper fraction 1015/12, which is 84 7/12 as a mixed fraction in its simplest form.
