Answer:

The change in available disk space is −6% per episode

Step-by-step explanation:

Given that :

Available disk space changed from 81% to 9% after recording 12 episodes of a show

Each episode requires the same amount of disk space

Change in disk space =

Final % = 9%

Initial percentage = 81%

Change = final value - initial value :

(9 - 81)% = -72%

72% reduction in disk space

Space taken up per episode :

Reduction in space / number of episodes

= -72% / 12

=- 6%

Celina can walk 4 miles in 1 hour and can run 8 miles in 1 hour. What percent of Celina’s average running speed is her average w
Valentin [98]
Okay. So, we're looking for the percentage of Celina's running speed as her walking speed. Her running sped is 8 mph and her walking speed is 4mph. All we have to do is 4/8 = x/100. You put change/original and x/100, because we're looking for the percent of change from running speed to walking speed.  Cross multiply the values to get 400 = 8x. Divide each side by 8 to isolate the "x". 400/8 is 50. x = 50. Celina's walking speed is 50% of her running speed. The answer is B: 50%.

A spherical container has a radius of 9 centimeters. It is filled with a solution that costs $2.10 per cubic centimeters.
vitfil [10]
Hello! For this question, first, we have to find the area of the spherical container. The formula for finding the area of a sphere is 4/3πr³. We raise the radius to the 3rd power and multiply it by pi (3.14). The radius is 9 cm. 9³ is 729. There's that number. Now, we multiply 81 by 3.14 to get the total area of the square. 729 * 3.14 is 2,289.06. Now, multiply that by 4/3. 2,289.06/1 * 4/3 is 3,052.08. The volume of the sphere is 3,052.08 cubic centimeters. Which brings us to the next part. Now, we can find the price of the solution by multiplying the area by the price. 3,052.08 * 2.10 is 6,409.368 or 6,409.37 when rounded to the nearest cent. The total value of the solution in the container is $6,409.37.
