Answer:
Option 4.
Step-by-step explanation:
Reciprocal of the second fraction turns the product into the division of the two fractions, which equals to 1.
Two fractions are said to be the reciprocal or multiplicative inverse of each other, if their product is 1.
Step-by-step explanation:
it is a multiple of 21.
the highest common factor of 2 numbers is the longest combination of prime factors they have in common.
the prime factors of 21 are simply
3×7
if another number A shares this as the longest combination of prime factors, that means it contains 3×7 itself in its prime factors.
and that means this number A can only be a multiple of 3×7 (= 21), as other prime factors present would be the factor of 21.
In order for them to work the same amount of time, you would have to make Lucas work for five hours (so he could have the same minimum time as Jonathan). So multiply Lucas's 30 minutes by five, and that equals a total of 2 hours and 30 minutes. So when Jonathan works for five hours he plays for three hours, but when Lucas works for 5 hours he only plays for 2 hours and 30 minutes. So Jonathan spends more time playing video games.
The answer would be c, a line is different from a line segment because a line continues on in both directions
(r^10)-2 would be the expression
