A² + b² = c²
30² + 72² = c²
<u />900 + 5,184 = c²
6084 = c²
(Square root both sides)
c = 78 m
<u />
so.... since the number after .81 is 1, it doesn't really round up to .82, so is just that, 15.81.
Answer:
Step-by-step explanation:
Divide: 1
3 : 14 = 13 · 4 1 = 1 · 4 3 · 1 = 43
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 1
4 is 4 1
) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - one third divided by one quarter = four thirds.
