Step-by-step explanation:

The brown cows produced more milk than the white cows in the given situation.

"Same amount" means that two or more quantities are equal to each other in terms of their numerical value or quantity.

To find out whether the brown cows produce more milk or the white cows, we can make a ratio of milk produced by both the herds in one day.

For this, let’s assume the amount of milk produced by a white cow in one day is “w” and the amount of milk produced by a brown cow in one day is “b”.

Then, The amount of milk produced by eight white cows in 1 day = 8w.

The amount of milk produced by six brown cows in 1 day = 6b.

The amount of milk produced by six white cows in 1 day = 6w.

The amount of milk produced by ten brown cows in 1 day = 10b.

According to the given condition, both herds produce the same amount of milk in one day.

Therefore, 8w × 10 = 6w × 86w × 5/3

                               = 10b5w/4 = 5b/2b

                               = (5w/4) × (2/5)

                               = w/2

We can say that a brown cow produces double the milk produced by a white cow. Hence, brown cows produced more milk than the white cows in the given situation.

The year in which the approximate cost of a pizza was of $9 is given as follows:

2000.

The rule of 72 is a quick and simple mathematical formula that is used to estimate the number of years it takes for an investment or a debt to double, given a fixed annual interest rate. The rule states that if you divide 72 by the annual interest rate (expressed as a percentage), the result will give you an approximate number of years it takes for the investment or debt to double.

Hence the equation is given as follows:

Time to double = 72/Rate.

The rate for this problem is of 3.25%, hence the time to double is given as follows:

T = 72/3.25

T = 22 years.

Hence the pizza cost half of what it cost in 2022 in 22 years before, hence:

2022 - 22 = year of 2000.

The area of each small triangle is equal to √(7)/8 times the square of the length of one side of the square.

First, we need to find the area of the larger triangle that is created by placing the two small triangles on top of the square. Let's call the base of the larger triangle "b" and the height of the larger triangle "h".

To find "b", we can use the length of one side of the square since the two small triangles are placed on top of the square. Let's call the length of one side of the square "s".

Since the two small triangles are congruent, we know that the base of each small triangle is equal to half of one side of the square, which is s/2. Therefore, the total base of the larger triangle is equal to the sum of the bases of the two small triangles, which is s/2 + s/2 = s.

To find "h", we need to use the Pythagorean theorem since the larger triangle is a right triangle. Let's call the hypotenuse of the larger triangle "c". Since the hypotenuse is the diagonal of the square, we know that its length is √(2)*s.

Using the Pythagorean theorem, we can find the height of the larger triangle:

h² + (s/2)² = c² h² + (s/2)² = (√(2)s)² h² + s²/4 = 2s² h² = 7s²/4 h = √(7)/2 x s

Now that we have found "b" and "h", we can use the formula for the area of a triangle:

Area = 1/2 x base x height

Area of the larger triangle = 1/2 x s x √(7)/2 x s = √(7)/4 x s²

Finally, we can find the area of each small triangle by dividing the area of the larger triangle by two:

Area of each small triangle = 1/2 x (√(7)/4 x s²) = √(7)/8 x s²

Step-by-step explanation:

In this question, we are asked to find the natural log of 28.1 and the log base 10 of 2/5, rounded to the nearest thousandth.

The natural log of a number x is what power the constant e is raised to to get x.

For example,

ln(e²) = 2

We can approximate ln(28.1) by inputting it into a calculator.

ln(28.1) ≈ 3.33576957634

Then, we can round this to the nearest thousandth.

ln(28.1) ≈ 3.336

Notice how the 7 in the ten-thousandths place is greater than or equal to 5, so we round the thousandths place digit up to 6.

Answer:

6√3 cm.

Step-by-step explanation:

The angle between the length of a rectangle and its diagonal is 30°. If the length of the rectangle is 6cm, find the length of the diagonal.

Let's call the width of the rectangle "w" and the diagonal "d". We know that the angle between the length and diagonal is 30 degrees, which means that the angle between the width and diagonal is 90 - 30 = 60 degrees (since the angles in a triangle add up to 180 degrees).

Now, we can use trigonometry to find the length of the diagonal. Specifically, we can use the sine function, which relates the lengths of the sides of a right triangle to the angles opposite them:

sin(angle) = opposite/hypotenuse

In this case, the angle we're interested in is 60 degrees, the opposite side is the width "w", and the hypotenuse is the diagonal "d". So we can write:

sin(60) = w/d

Solving for "d", we get:

d = w/sin(60)

Now we just need to find the width of the rectangle. Since we know the length of the rectangle is 6cm, we can use the fact that the opposite sides of a rectangle are equal to each other to write:

w = length*sin(30) = 6sin(30)

We can simplify sin(30) to 1/2, so:

w = 6/2 = 3

Now we can substitute this value of "w" into our expression for "d" to get:

d = w/sin(60) = 3/sin(60)

We can simplify sin(60) to √3/2, so:

d = 3/(√3/2) = 6/√3 = 2√3 * 2

So the length of the diagonal is 2√3 times the length of the width, or approximately 3.46 times the length of the width. Therefore, the length of the diagonal is:

d = 2√3 * 3 = 6√3 cm.

Abbey's acceleration is 0 m/s². Acceleration is the rate of change of velocity with respect to time.

If Abbey is running down the field at a constant speed of 10 m/s, then her velocity is not changing. Therefore, her acceleration is 0 m/s².

Mathematically, we can represent acceleration using the equation:

a = (v₂ - v₁) / t

Where,

a = acceleration

v₁ = initial velocity

v₂ = final velocity

t = time

In Abbey's case, her initial velocity (v₁) and final velocity (v₂) are the same, since she has a constant speed. Therefore,

v₂ - v₁ = 10 m/s - 10 m/s = 0 m/s

And since there is no change in velocity, her acceleration is 0 m/s².

So, Abbey's acceleration is 0 m/s².

What is meant by marginal frequency?

By dividing the sum or total of a row or the sum or total of a column by the total number of observations in a dataset, one can get the marginal relative frequency of a data set. This dataset is presented as a two-way table for ease of understanding. Although the percentage value is typically chosen, the marginal relative frequency can be stated as either a decimal or a percentage number.

Here,

The total number of middle school students = 21

Number of middle school students playing sports = 21 - 16 = 5

Number of high school students watching movies = 19-16 = 3

Total number of high school students = 11 + 3 = 14

Total number of students = 14 + 21 = 35

Now,

The marginal frequency of middle school students who chose to play sports = 5 / 35 = 0.143

The marginal frequency of high school students who decided to watch movies/TV = 3/35 = 0.0857

The marginal frequency of students in high school = 14/35 =0.4

The marginal frequency of students who chose to play sports = 15/35

                                                                                                     = 0.429

Tο shοw that ABCD is a parallelοgram, we need tο demοnstrate that bοth pairs οf οppοsite sides are parallel.

Let's begin by finding the slοpe οf each side using the fοrmula:

slοpe = (change in y) / (change in x)

Slοpe οf AB = (3 - (-1)) / (1 - 2) = 4/-1 = -4

Slοpe οf BC = (5 - 3) / (6 - 1) = 2/5

Slοpe οf CD = (1 - 5) / (7 - 6) = -4

Slοpe οf DA = (-1 - 1) / (2 - 7) = -2/5

Nοw, we can use the fact that twο lines are parallel if and οnly if their slοpes are equal. Thus, we need tο check whether AB is parallel tο CD and whether BC is parallel tο DA.

AB is parallel tο CD if their slοpes are equal. Since the slοpe οf AB is -4 and the slοpe οf CD is alsο -4, we can cοnclude that AB is parallel tο CD.

BC is parallel tο DA if their slοpes are equal. Since the slοpe οf BC is 2/5 and the slοpe οf DA is alsο 2/5, we can cοnclude that BC is parallel tο DA.
