The approximate length of each side of the park is 85m .

Pythagoras Theorem states that the sum square of two sides of triangle is equal to the  square of longest side.

According to the question

given that the park is a square

and in square the longest side is it's diagonal and the diagonal is  given to be 120m.

In square all sides of square is same .

let the side be x.

By Applying Pythagoras Theorem in the given ΔABC

[tex]AB^{2} +BC^{2} =AC^{2}[/tex]

Substituting the values  we get

[tex]x^{2} +x^{2} =120^{2}[/tex]

[tex]2x^{2} =120^{2} \\ \\ 2x^{2} =14400\\ \\ x^{2} =7200[/tex]

[tex]x=\sqrt{7200} =60\sqrt{2}[/tex] = 84.85 ≅ 85

The property that justifies the following statement, 5(3 x+1)=15 x+5 is the distributive property.

Distributive property can be described as one of the properties of multiplication which states that if we multiply two or more values that are added together with a number then the result will be the same even if we multiply each value separately with that number and then add them together. This can be given as:

x(y + z) = xy + xz

Therefore, as 5 x 3 = 15 and 5 x 1 =5, we can write the equation 5(3x+1) as 15x + 5 as the result will be the same in both circumstances.

The distributive property not only justifies the equations when two or more values are added but also justifies the equations in which they are subtracted which can be given as:

x(y-z) = xy - xz

So, according to the distributive property, the statement, 5(3 x+1)=15 x+5 is valid.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The proportion of young men to young ladies on the school field trip was 3:1. assuming there were 10 a larger number of young men than there were young ladies.

Let 'B' be the number of boys and 'G' be the number of girls. Then the equations are given as,

B/G = 3/1

B = 3G                 ....1

B = G + 10          ....2

From equations 1 and 2, then we have

3G = G + 10

2G = 10

G = 5

Then the number of boys is given as,

B = 5 + 10

B = 15

Then the total number of students who went on the field trip will be given as,

⇒ 5 + 15

⇒ 20

Answer:

[tex]\frac{613}{1000}[/tex]

Step-by-step explanation:

When dividing 28 by 263.2, the approximate quotient is 0.1062 (rounded to four decimal places).

To divide 28 by 263.2, we can perform the division operation as follows:

Dividend ÷ Divisor = Quotient

Here, the dividend is 28, and the divisor is 263.2.

To simplify the division, we can remove the decimal point by multiplying both the dividend and divisor by a power of 10. In this case, we can multiply by 10 to eliminate the decimal point.

28 * 10 = 280

263.2 * 10 = 2632

Now, we can perform the division:

280 ÷ 2632 ≈ 0.10621761658

Hence, when dividing 28 by 263.2, the approximate quotient is 0.1062 (rounded to four decimal places).

In summary, to divide a number by another number, we divide the whole numbers and the decimal numbers separately, considering the appropriate place values, and then combine the results to obtain the final quotient.

By solving a system of equations we can see that the quadratic equation is:

y = x^2 + 3x + 10

A general quadratic equation is given by:

y = a*x^2 + b*x + c

We want this quadratic equation to pase through the points (-2, 8), (1, 14), and (0, 10).

using the last point, we know that when x = 0, we must have y = 10, then:

10  = a*0^2 + b*0 + c

10 = c

So our quadratic equation is:

y = a*x^2 + b*x + 10

Now we use the other two points to write a system of equations:

8 = a*(-2)^2 + b*(-2) + 10

14 = a*(1)^2 + b*1 + 10

If we simplify these, we get:

-2 = 4*a - 2b

4 = a + b

Isolating a in the second equation we get:

a = 4 - b

Now we replace that in the other equation:

-2 = 4*(4 - b) - 2b

-2 = 16 - 4b -2b

-2 - 16 = -6b

-18/-6 = b = 3

Now that we know the value of b, we replace it in the equation for a:

a = 4 - b = 4 - 3 = 1

A linear equation is an algebraic equation in which each term has an exponent of one and when graphed produces a straight line. That's why it is considered a 'linear equation.'

Let a represent paid downloaded songs.

Total cost of songs downloaded = a x cost of each additional download.

a x $0.59 = $0.59a

The overall cost of downloaded songs is $15.34.

$15.34 =   $0.59a

Divide both sides of the equation by  $0.59.
