Answer:

After a translation, the measures of the sides and angles on any triangle would be the same since translation only involves changing the coordinates of the vertices of the triangle.

After a rotation, the measures of the sides and angles of a triangle would also be the same. Similar to translation, the proportion of the triangle is unchanged after a rotation.

After a reflection, the triangle's sides and angles would still be the same since reflection is a rigid transformation and the proportion of the sides and angles are not changed.

Step-by-step explanation:

Rigid transformations, i.e. translations, rotations, and reflections, preserve the side lengths and angles of any figure. Therefore, after undergoing a series of rigid transformations, the side lengths and angle measures of any triangle will be the same as the original triangle, generally speaking, in another position.

Answer:

They are all congruent or equal. The angles and side lengths are preserved through the rigid transformations.

Length of a text can be measured with ruler. Therefore, option C is the correct answer.

Everything around us has a measurement value, from the amount of sugar you put in a cake to the size of a football field. Each thing is measured differently based on its length, weight, volume, or duration. With these measurements, the idea of "Metric System" is introduced.

A ruler, sometimes called a rule, line gauge, or scale, is a device used in geometry and technical drawing, as well as the engineering and construction industries, to measure distances or draw straight lines.

Length of a text can be measured with ruler.

Step-by-step explanation:

560 divided 70 = 56 tens divided 7 tens is a true statement as RHS is equal to LHS.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, 560 divided 70 = 56 tens divided 7 tens, which can be numerically expressed as,

560/70 = 56×10/7×10.

560/70 = 560/70.

logarithm, the exponent or power to which a base must be raised to yield a given number.

                Hope this helps!

Note that the limit of the expression as x approaches infinity is 1/2.

start by multiplying both the numerator and denominator by the conjugate  expression

√ (x ² - 9x + 1) + x,

this will eliminates the root in the numerator

lim x->∞ [(√(x ² - 9x + 1) - x)  * (√(x² - 9x + 1) + x)] / (√(x² - 9x + 1) + x)

Expanding the numerator

lim x- >∞ [(x² - 9x + 1) - x^2] / (√(x² - 9x + 1) + x)

Simplifying further:

lim x->∞ [(1 - 9/x + 1/ x²)] / (√(1 - 9/x + 1 /x²) + 1)

we can see that the 1/x ² term approaches zero, and the expression simplifies to

lim x->∞ [(1 - 0)]  / (√(1 - 0) + 1)

= 1/2

So it is correct to state that the limit of the expression as x approaches infinity is 1/2.

Step-by-step explanation:

The brand C detergent has the best value.

The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations.

As per the given data in the question:

The information regarding the quantity and cost of 3 detergents is given in the question.

We have to find out which detergent is the most economical.

The detergent with the lowest cost/quantity will be the most economical.

For Brand A

Cost = $14.99

Quantity = 40 ounces

cost/quantity = 14.99/40 = 0.374 dollar/ounce

For Brand B

Cost = $19.99

Quantity = 50 ounces

cost/quantity = 19.99/50 = 0.399 dollar/ounce

For Brand C

Cost = $21.99

Quantity = 1/2 gallon = 64 ounces

cost/quantity = 21.99/64 = 0.343 dollar/ounce

The brand C detergent has the best value.

Hence, The brand C detergent has the best value.

The most appropriate choice for binomial distribution will be given by-

Mean of binomial distribution= 20

Standard deviation of binomial distribution = 16

What is binomial distribution?

Let there are n number of success or failure experiment called Bernouli trial and let p be the probability of success. Binomial distribution with parameters n and p is the probability distribution of p successes in n number of Bernouli trials.

Probability mass function of Binomial distribution

P(x = k) = \(n \choose k\)\(p^k(1-p)^k\)

Here,

n = 100,

p = \(\frac{1}{5}\\\)

1 - p = \(1 - \frac{1}{5}\)

       = \(\frac{5-1}{5}\)

       = \(\frac{4}{5}\)

Mean of binomial distribution = np

                                                 = \(100 \times \frac{1}{5}\\\)

                                                 =20

Step-by-step explanation:

Answer:

-6/1 or just -6

Step-by-step explanation:

15/4 ÷ (-5/8) is -6/1 .

Find the reciprocal of the divisor

Reciprocal of (-5/8) : (-8/5)

Now, multiply it with the dividend

So, 15/4 ÷ (-5/8) = 15/4 × (-8/5)

= 15 × (-8)  = -120

   4 × (-5)   =  -20

After reducing the fraction, the answer is -6/1 or just -6.

240 soldiers were transferred to the other camp. Let's assume the number of soldiers transferred to the other camp is "x." we can solve for the unknown variable representing the number of soldiers transferred.

Initially, the food provision was planned for 800 soldiers for 35 days. This means that the total food supply is equal to 800 soldiers multiplied by 35 days, which gives us a total of 28,000 soldier-days of food.

After some soldiers were transferred, the remaining soldiers had enough food to last for 50 days. So the food supply for the remaining soldiers can be calculated as the product of the number of remaining soldiers and the number of days, which gives us (800 - x) * 50 soldier-days of food.

Since the amount of food remains the same, we can set up the following equation:

\(28,000 = (800 - x) * 50\)

Now, let's solve this equation to find the value of x, representing the number of soldiers transferred to the other camp:

\(28,000 = 50 * 800 - 50x28,000 = 40,000 - 50x50x = 40,000 - 28,00050x = 12,000x = 12,000 / 50x = 240\)

By setting up the equation based on the total food supply for the initial and remaining soldiers, we can solve for the unknown variable representing the number of soldiers transferred. In this case, 240 soldiers were transferred to the other camp.

The length of a rectangular plot is 8 feet more than its width.

The Area of the rectangular plot is 609 square feet.

If the length of the rectangular plot is a then the width will be (a - 8) since it is given that length is 8 feet more than its width.

Now recall that the area of rectangular shape is given by

Where w is the width and l is the length.

We have

l = a

w = (a - 8)

A = 609

Substituting these values into the formula

you can also write it as

So option (B) is a correct option.

Now let us simplify the above equation

So option (E) is also a correct option.

Therefore, the following equations can be used to find the length (a) of the rectangular plot.

The measure of the height of the triangle is 3 / 8 units.

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

The trigonometric functions, also known as circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given that the triangle has sides, 3 / 4 cm, 1 cm, and 5 / 4 cm.

The angle of the triangle is,

tanθ = ( 1 ) / ( 3 / 4 )

tanθ = 1.33

θ = 53.6°

The height will be,

h = ( 3 / 4 ) x sin53.4

h = 0.6

h = 4 / 5 cm

The black market refers to the illegal trade of goods and services that are not permitted by law, such as drugs, counterfeit items, and stolen goods. Producers and consumers in the black market are motivated by a variety of factors, including:

High profits, Producers in the black market can earn higher profits than they would in legal markets due to the lack of regulation and taxes.

Escaping legal consequences: Producers and consumers may participate in the black market to avoid legal consequences, such as fines or imprisonment, for engaging in illegal activities.

Limited availability, Some goods and services are only available on the black market due to legal restrictions or limited supply.

Low prices, Consumers in the black market can often purchase goods and services at lower prices than in legal markets due to the lack of taxes and regulations.

Desire for anonymity, The black market can provide anonymity for both producers and consumers, allowing them to engage in illegal activities without fear of detection or retribution.
