As we know 1 kilometer = 39370.079 inches

and, 8.39 kilometer = 330,315 inches.

Kilometers: - It is a unit of length in the international system of units (SI) equal to one thousand meters. It is now the measurement unit used for expressing distances between geographical places on land in most of the world.

Inches: - It is a unit of length in the British imperial and united states customary system of measurement. It is equal 1/36 yard or 1/12 of a foot.

To convert a kilometer measurement to an inch measurement, multiply the length by the conversion ratio.

Since 01 kilometer = 39,370.07874 inches,

We can use this simple formula to convert:

          inches = kilometers × 39,370.079

Now, according to the question:

inches = 8.39 × 39370.079

The probability that a 3 will be rolled would be 0.125 and the expected number of 6's roll would be 68.

What is probability?

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

The events' estimated probabilities are as follows, according to the exponential probability theory:

P(3) = 0. 125

P(6 in 500 rolls) = 68 rolls

Number of times event occurs / number of trials

A number of attempts = sum of frequency:

(12+35+11+23+7+12) = 88

So the probability that a 3 will be rolled as

⇒ number of 3's / number of attempts

⇒ 11/88 = 0.125

The number of 6's probable in 500 rolls

⇒ (12 /88) × 500

⇒ 68.18 = 68

Therefore, the expected number of 6's roll would be 68.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

In the isosceles triangle,

Two sides are,

⇒ PR = 5n and QR = (32 + n)

Now,

Since, The triangle is an isosceles triangle.

So, Two sides are equal.

We formulate;

5n = 32 + n

5n - n = 32

4n = 32

n = 8

Thus, The length of side PR = 5n

The two equations for this system are C = 0.60f + 15 and C = 0.80f + 13.

The number of fish for which the cost is the same is 10 fishes.

The cost of this fish is equal to $21.

In order to write a system of linear equations to model and describe this situation, we would assign variables to the number of fish and the cost of fish respectively, and then translate the word problem into algebraic equation as follows:

Note: 1 dollar is equal to 100 cents.

Since the starter aquarium kit costs $15 plus 60 cents per fish at wet pets, we have:

C = 0.60f + 15     ........equation 1.

Since the starter aquarium kit costs $13 plus 80 cents per fish at gills and frills, we have:

C = 0.80f + 13          ........equation 2.

Next, we would solve the system of equations as follows:

0.80f + 13 = 0.60f + 15

0.80f -0.60f = 15 - 13

0.20f = 2

Number of fish, f = 2/0.20

Number of fish, f = 10 fishes.

From equation 1, we have:

Cost of fish, C = 0.60f + 15

Cost of fish, C = 0.60(10) + 15

Cost of fish, C = 6 + 15

Cost of fish, C = 21 dollars.

Answer:

235.15 sq.cm

Step-by-step explanation:

Perimeter of a triangle is sum of all three sides.

    Ratio of sides = 5 : 6 : 7

Sides are 5x , 6x , 7x

  Perimeter = 72 cm

5x + 6x + 7x = 72

Combine like terms.

             18x  = 72

Divide both sides by 18,

                x = 72÷ 18

               x = 4

5x = 5*4 = 20 cm

6x = 6*4 = 24 cm

7x = 7*4 = 28 cm

Sides: 20cm , 24 cm , 28 cm

So, it is a scalene triangle.

   To find the area of scalene triangle use Heron's formula.

a = 20 cm  ; b = 24 cm and c = 28 cm

   [tex]\sf s = \dfrac{a + b+ c}{2} \ where \ s \ is \ the \ semi \ perimeter.[/tex]

      [tex]\sf =\dfrac{72}{2}\\\\\\ = 36 \ cm[/tex]

    s - a = 36 - 20 = 16 cm

   s -b   = 36 - 24 = 12 cm

   s - c  = 36 - 28 = 8 cm

          [tex]\sf \boxed{Area = \sqrt{s(s-a)(s-b)(s-c)}}[/tex]

The two numbers that we requires are; y=−3+3√5 or y=−3−3√5

We know that in this question, we are required to obtain the two numbers that multiply to -36 and add up to -6. Now we have to write the problem into a system of simultaneous equations.

Thus;

Let the numbers by x and y

x + y = -6 ---- (1)

xy = -36 ------ (2)

x = -36/y ------ (3)

If we substitute (3) into (1)

-36/y + y = -6

-36 + y^2/y = -6

Multiply through by y

-36 + y^2 = -6y

The value of (5 - 6b)² when it is expanded is 25 -60b + 36b² (third option).

The square of a number is the value derived when a number is multiplied by itself. Multiplication is the mathematical operation that is used to determine the product of two or more numbers. The sign that is used to represent multiplication is x.

The square of a number is denoted by the power 2. For example, the square of 2, 2² is 4 (2 x 2).

Thus, (5 - 6b)² is the same as (5 - 6b) x (5 - 6b).

When multiplied, the expression becomes:

(5 - 6b) x (5 - 6b)

d. The standard form of the line is 3y - 5x = -44

The equation of a line can be represented in different form such as slope intercept form, standard form, general form and point slope form.

The standard form of an equation is represented as follows;

A x + By  = C

where

Therefore,

let's find the slope of the line passing through (7, -3) and (4, -8).

m = slope = - 8 + 3 / 4 - 7

m = -5 / -3

m = 5 / 3

The point slope form is represented as follows;

y - y₁ = m(x - x₁)

using (7, -3)

y + 3 = 5 / 3 (x - 7)

Let's rearrange the equation into standard form.

y + 3 = 5 / 3 (x - 7)

y + 3 = 5 / 3 x - 35 / 3

y - 5 / 3 x  = - 35 / 3 - 3
