Write the mixed numbers as improper fractions.
Rewrite thedivision problem using the improper fractions.
So to divide mixed numbers you should change the fractions to improper fraction and the convert the problem to a multiplication question.
Answer:
First option: 3
Step-by-step explanation:
To solve for side 'a', use the Pythagorean Theorem
<em>a² + b² = c² </em>
where "c" is always the longest side called the hypotenuse,
"a" and "b" are the two shorter sides called legs.
<u>Substitute </u><u>c = 5</u><u> (hypotenuse) and </u><u>b = 4</u>
a² + b² = c²
a² + (4)² = (5)²
<u>Square the numbers you know</u>
a² + 16 = 25
<u>Subtract 16 on both sides to isolate 'a'</u>
a² = 25 - 16
a² = 9
<u>Find the square root on both sides</u>
a = √9
a = 3
1) 6 - 5.55 = 0.45 feet (the difference between 6 and 5.55)
2) 0.45/6 * 100 = 7.5% (the percentage of error in Celina's measurement)
4m+4n=36
2m2=32
So ans is 4 which is m
