Answer:

21

Step-by-step explanation:

6(y^2) - 24y -51 = 6 4 - 24y - 51

(6 4) - (24y) - 51 = 24 - -48 - 51

(24 - -48) - 51 = 72 - 51

72 - 51 = 21

Y= 80.55% approximately, 80.6% rounded up

Calculations:

The percent (percentage) of a given number p/q can be found, for the most part, without a calculator by a slight change in the notation:

y=the number 29/36 expressed as a percent becomes

y=[29(2.7777777778 approx.)]/[36(2.7777777778 approx.)]

y=0.8055 approx. (Express the decimal numeral as a percent)

y=0.8055(100)

y=

80.55% approx., which is 80.6% rounded up to the nearest tenth percent

4.63 repeated in simplest form ( please reply quickly)
Natasha_Volkova [10]

Answer:

<u>4.63 as simplified fraction is</u>

<u>463/100</u>

Step-by-step explanation:

<em>4.63 as a fraction in simplest form</em>

<em>To convert 4.63 to fraction, follow these steps:</em>

<em />

<em>First write down the decimal number divided by 1 like this:</em>

<em />

<em>4.63/1</em>

<em />

<em>As we have 2 digits after the decimal point in the numerator, we need to multiply both the numerator and denominator by 10² = 100, so that there is no decimal point in the numerator</em>

<em />

<u><em>4.63 × 100</em></u>

<em>    1 × 100</em>

<em> = </em>

<em>463/100</em>

<em />

<em>As the numerator is greater than the denominator, we have an improper fraction, so we can also express 4.63 as a mixed number, thus 463/100 is equal:</em>

<em />

<em>4 63/100</em>
