Therefore, the value of x in the right triangle is 24 cm.

A triangle is a two-dimensional geometric shape that has three straight sides and three angles. It is formed by connecting three non-collinear points. The sum of the interior angles of a triangle is always 180 degrees, and the measure of each angle depends on the lengths of the sides and the type of triangle. There are different types of triangles based on their side and angle measures, such as equilateral, isosceles, scalene, acute, right, and obtuse triangles. Triangles have various properties and formulas that are used in geometry and other fields.

Here,

In a right triangle, the side opposite to the right angle is the longest side and is called the hypotenuse. Therefore, in this case, 25 cm is the hypotenuse of the triangle.

Using the Pythagorean Theorem, we can find the missing length x:

a² + b² = c²

where a and b are the lengths of the legs of the right triangle and c is the length of the hypotenuse.

In this case, a = 7 cm, b = x, and c = 25 cm.

Substituting these values into the Pythagorean Theorem, we get:

7² + x² = 25²

49 + x² = 625

x² = 625 - 49

x² = 576

x = √576

x = 24

The perimeter of the pond is 2.92 meters.

A right-angled triangle is a triangle in which one of the angles measures exactly 90 degrees, also known as a right angle.

The side opposite the right angle is called the hypotenuse, and the other two sides are called the legs.

The perimeter of a right-angled triangle is the sum of the lengths of its three sides.

Here we have

The Hypotenuse of the triangle is 1.46 m    

The angle between hypotenuse and perpendicular height = 73°

From triagonometric ratios,

=> cos A = Perpendicular height/ Hypotenuse.

=> cos (73) = Perpendicular height/1.46

=> Perpendicular height = 1.46 × 0.29 = 0.42 m

As we know from Pythagoras' theorem,

Hypotenuse² = side² + side²    

Side = √Hypotenuse² - side²  

= √[(1.46)²- (0.42)²]  = 1.04

Therefore, the sides of the pond are 1.46 m, 0.42 m, and 1.04

Hence, perimeter of the pond =  1.46 + 0.42 + 1.04 = 2.92 meters  

Therefore,

The perimeter of the pond is 2.92 meters.

Using the arrangements formula, it is found that the number is in position 697.

-----------------------

The number of possible arrangements of n elements is given by:

\(A_n = n!\)

In this problem, the numbers are sorted as:

Number of elements which we do not start with 8.

Thus:

\(n = 5 \times 5! = 600\)

Numbers that start with 8, and the second element is not 7.

Thus:

\(n_2 = 4 \times 4! = 96\)

Total:

\(600 + 96 = 696\)

872456 is the first number which starts with 87, thus it is at position 697.

a. To determine whether the proportion of adults using social media is equal for all four countries, we can conduct a hypothesis test. The null and alternative hypotheses are as follows:

H0: The proportion of adults using social media is equal for all four countries

Ha: The proportion of adults using social media is not equal for all four countries

For the test, we will use a 0.05 level of significance.

b. The sample proportions for each of the four countries are as follows:

United Kingdom: P1 = 480 / (480 + 320) = 0.60

China: P2 = 215 / (215 + 285) = 0.43

Russia: P3 = 343 / (343 + 357) = 0.49

United States: P4 = 640 / (640 + 360) = 0.64

c. To conduct multiple pairwise comparison tests among the four countries, we will use the following formula:

Pi - Pj / √(P(1-P)(1/n1 + 1/n2))

Where Pi and Pj are the proportions for two countries, n1 and n2 are the sample sizes for two countries.

United Kingdom vs. China: Diff = 0.60 - 0.43 / √(0.51*0.49*(1/800 + 1/600)) = 0.17 / 0.03 = 5.67

United Kingdom vs. Russia: Diff = 0.60 - 0.49 / √(0.51*0.49*(1/800 + 1/700)) = 0.11 / 0.03 = 3.67

United Kingdom vs. United States: Diff = 0.60 - 0.64 / √(0.51*0.49*(1/800 + 1/1000)) = -0.04 / 0.03 = -1.33

China vs. Russia: Diff = 0.43 - 0.49 / √(0.57*0.43*(1/500 + 1/700)) = -0.06 / 0.04 = -1.50

China vs. United States: Diff = 0.43 - 0.64 / √(0.57*0.43*(1/500 + 1/1000)) = -0.21 / 0.04 = -5.25

Russia vs. United States: Diff = 0.49 - 0.64 / √(0.51*0.49*(1/700 + 1/1000)) = -0.15 / 0.03 = -5.00

Since the level of significance is 0.05 and all of the calculated differences in proportions are less than the critical value (1.96), we fail to reject the null hypothesis and conclude that there is no significant difference between the proportion of adults using social media in the four countries.

The equation that can be used to calculate the concrete weight, w = k·v, and the 740 pounds weight of 5 cubic feet concrete, gives the value of k (which is the density of the concrete) as 148 lb/ft³

The density of a material is the ratio of the mass of the material to its volume.

(b) The weight, w of the concrete is directly proportional to the volume, v of the concrete

The weight of 5 cubic feet = 740 pounds

The equation that can be used to calculate the weight of a given volume of concrete is; w ∝ v

Where;

k = The constant of proportionality

Which gives;

\(k = \dfrac{w}{v}\)

In a proportional relationship between two variables, one variable is a constant multiple of the other such that the ratio of the two variables is a constant, k, which can be found using the value for the data point in the question;

The correct expression is 5/a = 1. There is no need to introduce an additional variable "x".

In such a fraction, the value that appears above the horizontal line is referred to as the numerator.

It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.

The error in the reasoning is that it assumes that multiplying the second fraction by "x" will result in an equivalent expression to 5/a. However, this is not necessarily true.

To correct the error, we can use the property of reciprocals, which states that if a/b = c/d, then b/a = d/c. Using this property, we can rewrite the given equation as:

a/5 = b/3

5/a = 3/b (multiplying both sides by 5/a)

5/a = (b/3) * (3/b) (multiplying both sides by the reciprocal of b/3)

5/a = 1

Therefore, the correct expression is 5/a = 1. There is no need to introduce an additional variable "x".

We need to select the correct simplification for this.

We know that, \(\sqrt[a]{x} =x^{\dfrac{1}{a}}\)

So,

\(\sqrt[4]{2} =(2)^{\dfrac{1}{4}}\)

Also, \((x^a)^b=x^{a\times b}\)

So,

\((2^{\dfrac{1}{4}})^4=2^{\dfrac{1}{4}}\times 2^{\dfrac{1}{4}}\times 2^{\dfrac{1}{4}}\times 2^{\dfrac{1}{4}}\\\\=2^{\dfrac{1}{4}+\dfrac{1}{4}+\dfrac{1}{4}+\dfrac{1}{4}}\\\\=2^1\\\\=2\)

Question:

A company produces boxes of DVDs at a rate of 52 boxes per hour they begin to produce boxes when they first opened for the day and after 3 hours have 400 boxes in stock.

- How many boxes were in stock when they opened?

- Write a linear model for the amount of boxes, b, as a function of the number of hours since they opened, h.

- Use your model to predict the number of boxes in stock at the end of an 8 hour shift.

Answer:

1. \(Initial = 244\)

2. \(b = 244 + 52h\)

3. 660 boxes

Step-by-step explanation:

Given

\(Rate = 52\ per\ hour\)

\(Total\ boxes\ in\ 3\ hours = 400\)

Solving (a): Initial Number of boxes

First, we calculate the number of boxes made in 3 hours

\(Boxes = Rate * Hours\)

\(Boxes = 52 * 3\)

\(Boxes = 156\)

If they had 400 boxes at the 3rd hour.

Then, the number of boxes when they opened is:

\(Initial = 400 - 156\)

\(Initial = 244\)

Solving (b): Linear function

\(b = boxes\)

\(h = hours\)

Since, we have the rate and the initial number of boxes.

The linear function is:

\(Boxes = Initial + Rate * Hours\)

i.e.

\(b = 244 + 52 * h\)

\(b = 244 + 52h\)

Solving (c): Boxes at the end of the 8th hour

We have:

\(b = 244 + 52h\)

In this case:

\(h = 8\)

Substitute 8 for h

\(b = 244 + 52 * 8\)

\(b = 244 + 416\)

\(b = 660\)

Hence, there are 660 boxes at the end of the 8th hour
