Enter your answer as a simplified fraction formatted like this: 42/53
expeople1 [14]

Answer:

\displaystyle -0.\overline{37}=-\frac{37}{99}

Step-by-step explanation:

<u>Convert a Repeating Decimal to a Fraction </u>

We need to convert the following decimal to a fraction:

-0.\overline{37}

Let's call x to the given number:

x=-0.\overline{37}

The number has two repeating (periodic) decimals, thus we multiply by 100:

100x=-37.\overline{37}

Note the decimals continue to repeat exactly like the original number.

Subtracting both expressións, the repeating decimals are simplified:

100x - x = -37

Operating:

99x=-37

Dividing by 99:

\displaystyle x=-\frac{37}{99}

The fraction cannot be simplified, thus:

\mathbf{\displaystyle -0.\overline{37}=-\frac{37}{99}}

PLZZZZZ NEED HELP!!!!!!
mylen [45]

Remember the rules of Sohcahtoa (Sine, cosine, tangent). For this problem we take the cosine of 38 because the labeled sides are the adjacent leg and the hypotenuse.

Cos(38)=79/x

Cosine of 38 is about 0.7880

0.7880=79/x

Next we multiply both sides by the denominator

(x) 0.7880=79 (x)

Then divide.

<u>0.7880x</u>= <u>79</u>

0.7880 0.7880

X=100.25

Hope this helped :)
