Answer:

<h2><u><em>a = 13/4</em></u></h2>

Step-by-step explanation:

√(5²+12²) = ∛(64a³)

√(25+144)=√(64a)

√169 = √(64a)

13 = 4a

Rewrite the fraction in the sentence below as a percentage.
scoray [572]

Answer:

86%

Step-by-step explanation:

A percentage is a number or a ratio expressed as a fraction over 100. For example, 50% in fraction form is known as 50/100. 45% is known as 45/100.

Lets say the fraction was 43/50. We already know that a percentage is a number expressed as a fraction over 100, in order to convert this fraction into a percentage, we would have to multiply the denominator by a certain number in order to make it 100.

43/50 = x/100

If we multiply 50 × 2 = 100, so now we have to do the same for the numerator, and also multiply it by 2.

43 × 2 = 86

50 × 2 = 100

Now we know that the fraction is 86/100, now in order to convert it into percantage form, it would just be 86%
