Phantasy [73]

Answer: Ari watched 5/12 of the movie at night.

Step-by-step explanation:

Let x represent the portion of the movie that Ari watched at night.

Ari watched 1 4 of a movie in the morning, and she watched some more at night. It means that the total portion she has watched already is 1/4 + x

The portion of the movie remaining for her to watch is

1 - (1/4 + x) = 1 - (1 + 4x)/4

By the end of the day, she still had 1 3 of the movie left to watch. It means that

1/3 = 1 - (1 + 4x)/4

1/3 = (4 - 1 - 4x)/4

1/3 = (3 - 4x)/4

Cross multiplying by 3, it becomes

1 = 3(3 - 4x)/4

Multiplying through by 4, it becomes

4 = 3(3 - 4x)

4 = 9 - 12x

12x = 9 - 4

12x = 5

x = 5/12

The question and answer choices are listed in the picture.

Given:
$L=2 \pi r( \frac{x}{360})$

Solution:
If we want to find the solution for r, we need to move the r to the left side first. So I reverse the side
$2 \pi r( \frac{x}{360})=L$

Move 2π to the right side. Because on the left side 2π acts as numerator, after it's moved to the right side, it becomes denominator.
$2 \pi r( \frac{x}{360})=L$
$r( \frac{x}{360})= \frac{L}{2 \pi }$

Move 360 to the right side. Because on the left side 360 acts as denominator, after it's moved to the right side, it becomes numerator.
$r( \frac{x}{360})= \frac{L}{2 \pi }$
$r(x)= \frac{360L}{2 \pi }$

Move x to the right side. Because on the left side x acts as numerator, after it's moved to the right side, it becomes denominator.
$r(x)= \frac{360L}{2 \pi }$
$r= \frac{360L}{2 \pi x}$

Then simplify the fraction
$r= \frac{360L}{2 \pi x}$
$r= \frac{180L}{ \pi x}$

The answer is second option
