The difference would be 10.
Change the mixed leading number into an improper fraction...a b/c=(ac+b)/c
19/7-7/8 the least common multiple of the denominators is 56 so:
(19/7)(8/8)-(7/8)(7/7)
(152-49)/56
103/56 now we can change back into a mixed number...
(56+47)/56
1 47/56
Answer:
C.
Step-by-step explanation:
According to theorem, "the measure of central angle of minor Arc of a circle is doubleto that of the angle subtended by the corresponding major Arc."
So
m<AOB = 2(m<AZB)
m<AZB = M<AOB / 2
m<AZB = 68/2
m<AZB = 34°
7x20=140. 7x2000=14000. The only thing that changes the product of these numbers is the amount of zeros behind the 2. Since the only two numbers that affect the answer is the 7 and the 2. (7x2=14). The number of zeros behind the 2 affect how many zeros will be included in the product.
