Yes. There is the square root of 1. The square root of 1 is 1. The square root of 1 is always taken with positive sign. Square root of 1 is a rational number.

The square root of any number is an inverse mathematical operation of a square. square root is the the value which gives the number when it is multiplied by itself. The symbol √ is used to indicate the square root. A number is said to be a rational number that can be made by dividing an integer by an integer. It can be written as a fraction. There are so many ways to find square roots. whose square and the square root are equal is 1. It is neither prime nor composite. Square root of 1 is never be a negative number.

Answer:

(a) 7.68 dollars

(b) 1927.07 pesos

Step-by-step explanation:

Setting up a conversion factor will be helpful in helping us solve this problem. A conversion factor shows the relationship between two different units, and and is used to convert from one unit to the other.

Our conversion factor is 1 U.S. Dollar = 19.61 Mexican pesos. To convert units, we can turn the conversion factor into a ratio (U.S. dollar ÷ 19.61 Mexican pesos or vice versa) and then multiply the given amount by the ratio. The unit that we want to end up with should always be in the numerator, and the unit we want to convert from should always cancel out in the denominator. This will be demonstrated when we solve the problems below:

(a) We want to convert from pesos to dollars, so we will multiply by the conversion factor (1 dollar / 19.61 pesos).

(b) Now we want to convert from dollars to pesos, so we will multiply by the conversion factor (19.61 pesos / 1 dollar).

N(b) =75 because p(b) =n(b) /n(s)

0.75=n(b)/100

n(b)=0.75*100=75

The original price of the TV is $4691.5

percentage, a relative value indicating hundredth parts of any quantity.

Given that You walk into a store and see a sign that says "Tv: 47% off, only pay $1,500 today!"

We have to find the original price of the TV.

Convert 47% to decimal value.

47/100=0.47

Now multiply 0.47 with x which gives 1500

0.47x=1500

Divide both sides by 0.47

x=1500/0.47

x=$3191.48

Now add $1500 and $3191.5 to find the original price.

1500+3191.5

$4691.5

Hence, the original price of the TV is $4691.5

Answer:

√21 is irrational

Step-by-step explanation:

√21 = 4.58257569495584 which is a non-terminating decimal.

Therefore √21 is irrational.

Answer: No, it cannot be a rational number.

Step-by-step explanation:

A rational number is defined to be a whole number (ex. 1, 2, 3) or can be decimals that continuously repeat the digits after the point. In the case of a square root, they can be rational--but this only applies to perfect squares: √100, √64, √16, etc, which would give an outcome of a whole number. Therefore, √21 is not a rational number, as the decimal value is 4.57257, and is not continuous (ex. 3.666666).

The length of the shadow of Hayden is approximately 32 inches.

Charlie and Hayden are standing outside.  Charlie is 64 inches tall and casts a shadow of 30 inches.

Hayden is 68 inches tall. The length of the shadow of Hayden can be calculated as follows:

Using proportion,

64 / 30 = 68 / x

where

x = length of the shadow of Hayden

Therefore,

64 / 30 = 68 / x

cross multiply

64x = 68 × 30

64x = 2040

divide both sides by 64

x = 2040 / 64

x = 31.875

Hence,

In geometry and trigonometry, a right attitude is an angle of precisely ninety stages radians similar to 1 / a 4 turn. If a ray is placed in order that its endpoint is on a line and the adjacent angles are equal, then they may be right angles. The time period is a calque of Latin angulus rectus; here rectus manner "upright", regarding the vertical perpendicular to a horizontal baseline.

Closely related and crucial geometrical concepts are perpendicular strains, which means lines that form right angles at their factor of intersection, and orthogonality, which is the assets of forming right angles, usually implemented to vectors.

the triangles can be proved similar by AA congruence.

What is congruent of the triangle?

The shapes maintain their equality regardless of how they are turned, flipped, or rotated before being cut out and stacked. We'll see that they'll be placed entirely on top of one another and will superimpose one another. Due to their identical radius and ability to be positioned directly on top of one another, the following circles are considered to be congruent.

Any two figures can be perfectly positioned over one another to demonstrate their congruence. The relationship between two figures that are said to be congruent is described using the word "congruence."

As both the triangles are right angle so the left side triangle the angles are 90, 54 and 38.

The equation which represents the same line as the points in the table is y = -3/4 x + 2. (Option C)

The equation of the points given in the table can be determined by using the slope-intercept form which is given by:

y = mx + b

where m is the slope of the line and b is the y-intercept.

The slope of the line can be determined by:

m = rise/run = Δy/ Δx = (y2 – y1)/(x2 – x1)

Hence, taking two points from the table say (-4, 5) and (0, 2)

m = (2 – 5)/(0 – (-4)) = -3/4

y intercept is the value of y when x = 0

From the table, y-intercept b = 2

Where,

x is the logarithm of a number ‘b.’

‘a’ is the base of the log function.

Now,

Let us discuss how to find the value of log 2 using a common log function and natural log function.

The volume of a rectangular prism is given by the product of its length, width, and height, which is V = l * w * h, where l is the length, w is the width, and h is the height.

We are given that the volume of the prism is 3w^3 + 14w^2 + 8w. We can use this information to find the height of the prism by dividing the volume by the product of the length and width.

We know that the length of the prism is 2 more than three times the width (l = 3w + 2). Therefore, the product of the length and width is l*w = (3w + 2) * w = 3w^2 + 2w

Now we can divide the volume by the product of the length and width to find the height of the prism:

V / (l * w) = (3w^3 + 14w^2 + 8w) / (3w^2 + 2w) = 3w + 14 + 8/3w^2 + 2w

So, the height of the prism is 3w + 14 + 8/3w^2 + 2w

Which is a simplified expression for the height of the prism, in terms of the width.

So the value of x is 4.8

15x + 48= 120

Now we send the 48 on the right side.

15x= 120-48.

Here we subtract 48 from 120 we get

15x= 72

In the next step we divide the both sides with 15

15x/15= 72/15

x=4.8
