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}}

Given X(4, -7). What are the coordinates of X" if
Vika [28.1K]
<h3>Answer:</h3>

B. (0, 9)

<h3>Step-by-step explanation:</h3>

Reflection across x=a is represented by the transformation ...

... (x, y) ⇒(2a-x, y)

Reflection across y=b is represented by the transformation ...

... (x, y) ⇒ (x, 2b-y)

The double reflection, across x=2, y=1 will result in the transformation ...

... (x, y) ⇒ (2·2-x, y) ⇒ (4-x, 2·1-y) ⇒ (4-x, 2-y)

For (x, y) = X(4, -7), the transformed point is ...

... X''(4-4, 2-(-7)) = X''(0, 9)

Carrie is buying bulk candy for a high school fundraiser. She buys 1000 candy bars for $350. What is the unit cost per candy bar
liubo4ka [24]
1000 candy bars ... $350
1 candy bar ... $x = ?

If you would like to know what is the unit cost per candy bar, you can calculate this using the following steps:

1000 * x = 350 * 1
1000 * x = 350    /1000
x = 350 / 1000
x = $0.35

Result: She can buy 1 candy bar for $0.35, so the correct result would be B) $.35.
