How much wire will be needed to put a double fence around a square plot with 50m?

To find the ratio of the area of 11 million km² to the area of the Pacific Ocean (165 million km²), we can express it as a fraction:

Ratio = Area of 11 million km² / Area of the Pacific Ocean

Ratio = 11 million km² / 165 million km²

To simplify the fraction, we can divide both the numerator and the denominator by 11 million:

Ratio = (11 million km² / 11 million km²) / (165 million km² / 11 million km²)

Ratio = 1/15

Therefore, the ratio of the area of 11 million km² to the area of the Pacific Ocean is 1/15.

Emily can walk 3/4 of a mile in 1/4 of an hour. At the same rate, time taken to walk 1 mile =1/3 of an hour.

Mathematical representation

We know that, Emily can walk 3/4 of a mile in 1/4 of an hour.

Meaning,

Time taken to walk 3/4 of a mile = 1/4 of an hour

Distance covered = 3/4 mile

We need to find the time taken by Emily to walk 1 mile.

The rate is defined as the distance covered in unit time. So,

                        Rate = Distance / Time

We know that Rate of Emily = 3/4 ÷ 1/4

                                              = 3/4 × 4/1

                                              = 3 miles/hour

The rate of walking is 3 miles/hour.

Now we can find the time taken to walk 1 mile using rate formula.

             Distance = Rate × Time

We have to walk 1 mile and the rate of walking is 3 miles/hour.

             Time = Distance / Rate

Time taken to walk 1 mile = 1 / 3 = 1/3 hour.

Step-by-step explanation:

To enlarge a 4x6 photo with a ratio of 2:3, we can multiply the dimensions of the photo by the enlargement ratio to find the new dimensions.

Original photo dimensions: 4 inches x 6 inches

Enlargement ratio: 2:3

To find the new dimensions, we can multiply the original dimensions by the enlargement ratio:

New width = 4 inches x 2 = 8 inches

New height = 6 inches x 3 = 18 inches

Therefore, the new dimensions of the enlarged photo would be 8 inches x 18 inches.

The original price of the refurbished phone before the 35% discount was £120. If a refurbished phone is sold at a 35% discount with a final price of £78.

To find the original price of a refurbished phone before the discount of 35%, let's use the following formula:

discount = original price - discounted price

35% of the original price can be represented as 0.35 times the original price. This will result in the equation below:

0.35x = original price - 78

Where x is the original price. So, to find the value of x, we can rearrange the equation to get:

0.35x + 78 = original price

Now we substitute the given values into the equation above:

0.35x + 78 = original price

0.35x + 78 = x - 44.1 (if x represents the original price)

Let's subtract 0.35x from both sides to isolate the x variable:

78 = 0.65x

Then, let's divide both sides by 0.65 to solve for x (the original price):

To create a 40 L solution with a 45% acid concentration, a chemist combines a 25% acid solution and a 50% acid solution. Therefore, the chemist used 32 L of the 50% acid solution and (40 - 32) = 8 L of the 25% acid solution to create the 40 L solution with a 45% acid concentration.

Let's assume the chemist uses "x" liters of the 50% acid solution. Since the total volume of the mixture is 40 L, the remaining volume will be (40 - x) liters of the 25% acid solution.

The acid content in the 50% solution is 0.5x, while the acid content in the 25% solution is 0.25(40 - x).

To find the acid content in the final 45% solution, we multiply the acid concentration (0.45) by the total volume (40):

0.45 * 40 = 0.5x + 0.25(40 - x)

Simplifying the equation:

18 = 0.5x + 10 - 0.25x

Combining like terms:

0.25x = 8

Dividing both sides by 0.25:

x = 32

Cindy's current average score in Biology is:

(72 + 82 + 83 + 89) / 4 = 81.5

Since the final exam counts as two tests, we can calculate the total number of points Cindy can earn in the course as follows:

Total points = 4 tests + 2 tests = 6 tests

To earn a C in the course, her average score must be between 77 and 84. Let's assume she needs to score x on her final exam to achieve a C. Then her total points would be:

Total points = 72 + 82 + 83 + 89 + x + x

Simplifying this equation, we get:

Total points = 326 + 2x

To earn a C, Cindy's average score must be between 77 and 84. Therefore, we can set up an inequality:

77 <= (326 + 2x) / 6 <= 84

Multiplying both sides by 6, we get:

The mean, median, and range of Santos' train ride times for the week were as follows:

Mean: 49.4 minutes

The mean is calculated by adding up all the values and dividing the sum by the total number of values. In this case, the sum of the train ride times (48 + 51 + 48 + 48 + 50) is 245 minutes. Dividing this sum by the total number of days (5), we get the mean of 49.4 minutes.

Median: 48 minutes

The median is the middle value in a sorted list of numbers. To find the median, we arrange the train ride times in ascending order: 48, 48, 48, 50, 51. Since there is an odd number of values, the middle value is the median. In this case, the median is 48 minutes.

Range: 3 minutes

The range is the difference between the largest and smallest values in a set. To calculate the range, we subtract the smallest value (48 minutes) from the largest value (51 minutes). In this case, the range of the train ride times for the week is 3 minutes.

In summary, the mean train ride time for the week was 49.4 minutes, with a median of 48 minutes. The range of the train ride times was 3 minutes. These metrics provide insights into the average, central tendency, and variability of Santos' train rides throughout the week.

We can conclude that the relationship represented by the given equation is a function. Moreover, the pressure increases as the diver descends below sea level, which is shown by the positive slope (0.445) of the equation.

The equation y = 0.445x + 14.7 represents a situation where a diver descends below sea level. This equation gives the pressure (y) of the water at a depth of x feet below sea level. Here, y is dependent on x. It means that the pressure at a given depth is dependent on that particular depth. Therefore, we can say that the given equation represents a function because for each value of x, there is only one corresponding value of y.

A function is defined as a relation that maps each input value (x) to exactly one output value (y). In other words, it is a set of ordered pairs (x, y), where each value of x is paired with a unique value of y. The equation given above satisfies this definition of a function because it represents a one-to-one relationship between the depth (x) and the pressure (y) of the water.
