Answer:

The cost of one ounce of cereal is $0.24

Step-by-step explanation:

We are given the following information in the question:

Amount of cereals a box contain = 23.4 ounces

Cost of one box = $5.94

Cost of cereal per ounce =

Formula:

[tex]\text{Cost of one ounce of cereal} = \\\\\displaystyle\frac{\text{Cost of cereal}}{\text{Amount of cereal in a box}}[/tex]

Putting the values, we have:

[tex]\text{Cost of one ounce of cereal} = \displaystyle\frac{5.49}{23.4} = 0.2347 \approx 0.24[/tex]

Hence, the cost of one ounce of cereal is $0.24

Final answer:

The computer takes 15 minutes to download a 45-minute TV show, indicating a download speed of 3 minutes of video per 1 minute of download time. Applying this speed to a 2-hour (120 minutes) movie results in a download time of 40 minutes.

Explanation:

A particular computer takes 15 min to download a 45 min TV show. To find out how long it will take the computer to download a 2-hour movie, we need to establish the download speed based on the given information and apply it to the new download task.

The computer downloads a 45 min TV show in 15 min. This gives us a download ratio or speed of 3 minutes of video per 1 minute of download time (45:15 or, simplified, 3:1).

Since a 2-hour movie is 120 minutes, using the same download speed, we calculate the download time by dividing the movie's length by the speed ratio: 120 minutes / 3 = 40 minutes.

Therefore, it will take the computer 40 minutes to download a 2-hour movie.

The provided data is insufficient to accurately calculate the area of the polygon. With an assumption that the shape is a rectangle and the lengths are 15m and 8m, the area would be 120 square meters.

To calculate the area of a polygon, it's ideal to break down the polygon into simpler shapes like rectangles or triangles, for which we have well established formula for area. However, the information you've provided is inadequate to define a specific polygon shape like a rectangle or a square. Four sides could suggest a rectangle or a quadrilateral, but we don't know two essential properties: the arrangement of these sides and the measure of angles. For instance, if it was a rectangle, we'd look for pairs of equal lengths. If your shape is indeed a rectangle, and we assume that 15m and 8m are the length and width (or vice versa), we could calculate the area. For a rectangle, the area is calculated as length multiplied by width. In this case, it would be 15m*8m = 120 square meters.

Answer: The volume of water in the pool over time from when the hose is placed in the pool until the pool is full is defined by the equation [tex]V(t)=5000+1250t[/tex] and its graph is given below.

Explanation:

The total capacity of the pool is 20,000 gallon.

It is given that the pool contains 5000 gallons of water when a hose is placed in the pool and begins adding water at a rate of 1250 gallons per hour. So the initial volume of water is 5000.

Let the time is defined by t. So, the volume of water in the pool after time t is defined as,

[tex]V(t)=5000+1250t[/tex]

The capacity of the pool is 20,000 gallon, therefore the maximum value of V(t) is 20,000.

[tex]20,000=5000+1250t[/tex]

[tex]15000=1250t[/tex]

[tex]12=t[/tex]

The maximum value of t is 12, since the time is always positive, therefore we can say that,

[tex]0\leq t\leq 12[/tex]

The below graph representing the volume of water in the pool over time from when the hose is placed in the pool until the pool is full. The initial point is (0,5000) and the other point is (12,20000).

The plot of the graph representing the volume of water in the pool over time from when the hose is placed in the pool until the pool is full is shown below.

The volume of water in the pool over time from when the hose is placed in the pool until the pool is full is defined by the equation  [tex]V(t)=5000+1250x[/tex] and its graph is given below.

According to the question, [tex]\rm Volume=20,000\; gallons[/tex]

Let the time be defined by [tex]x[/tex].

So, volume of water is defined as,

[tex]V(t)=5000+1250x[/tex]

[tex]20000=5000+1250x[/tex]

[tex]x=12[/tex]

So, the range is

To find the measure of angle E in degrees that the sum of angles in a triangle is 180 degrees.

From the given triangle, two angles with measures 50 degrees each (angle A and angle B), and one angle with a measure of 80 degrees (angle D).

To find the measure of angle E, we can use the equation:

Angle E = 180° - (angle A + angle B + angle D)

Angle E = 180° - (50° + 50° + 80°)

Angle E = 180° - 180°

Final answer:

The distance between the points (9, -7) and (9, 4) is calculated by finding the absolute difference between the y-coordinates since the x-coordinates are the same. The distance is 11 units.

Explanation:

To calculate the distance between two points on a coordinate plane, you can use the distance formula, which is derived from the Pythagorean theorem. However, in this particular case, since the x-coordinates of the points (9, -7) and (9, 4) are the same, the distance is simply the absolute difference between the y-coordinates.

The formula to find the distance between two points (x1, y1) and (x2, y2) is:

d = √((x2 - x1)² + (y2 - y1)²)

So, substituting the known values:

d = √((9 - 9)² + (4 - (-7))²) = √(0 + 11²) = √121 = 11

Therefore, the distance between the points (9, -7) and (9, 4) on a coordinate plane is 11 units.
