130 to base six

130=_____six

Please show work.

We construct  an equation and calculate that number as 7 .

The equals sign is a symbol used in mathematical formulas to denote the equality of two expressions. The word equation and its cognates can have slightly different meanings in different languages. For instance, in English, an equation is any well-formed formula that consists of two expressions linked by the equals sign, whereas in French, an equation is defined as containing one or more variables.

The equation's solutions are the values of the unknown variables that satisfy the equality, which are often referred to as the variables for which the equation must be solved.

let the number be x .

9 times the number is = 9x

5 times the number added to 3 is

(x + 3) × 5

Now let us set up an equation and find that number :

(x + 3) × 5 = 9x - 13

Simplifying the given equation we get :

5 (x + 3) = 9x - 13

5x + 15 = 9x - 13

5x - 9x = - 13 - 15

- 4x = - 28

x = - 28/-4

x = 7

Hence the required number calculated from the equation is 7 .

Take the prime factorization of both numbers to find the GCF. Then list the characteristics that they share. If they have more than one of the same factor (for example, two 2's), write them both down. Then multiply the factors they share.

A positive integer's prime factors are the prime numbers that divide it exactly. Finding these numbers is known as integer factorization or prime factorization. According to the fundamental theorem of arithmetic, every positive integer has a unique prime factorization.

The GCF (Greatest Common Factor) of two or more numbers is the greatest number among the given numbers' common factors. The greatest common factor (GCF) of two natural numbers x and y is the largest possible number that divides both x and y without leaving any remainder. GCF can be calculated in three ways: division, multiplication, and prime factorization.

Use the pythagorean theorem to find side C

The right answer is 6.4

The vertex form of a parabola is expressed as

y = a(x - h)^2 + k

where

a is the leading coefficient

h and k are the horizontal and vertical coordinates of the vertex.

Recall, the general expression for a quadratic equation is

y = ax^2 + bx + c

By comparing with the given equation,

a = - 2, b = 36, c = - 171

The formula for the x coordinate of the vertex is

x = - b/2a

x = - 36/(2 * - 2) = - 36/- 4 = 9

Substituting x = 9 into the equation, we have

y = - 2(9)^2 + 36(9) - 171

y =

The graph of the linear equation:

y = -3x + 4

Can be seen in the image at the end.

To draw a line, we just need to find two points that belong to the line, graph them, and then connect them with a  line.

Here we know that we have the line:

y = k*x + 4

Where k = -3, then:

y = -3*x + 4

By evaluating this in a value of x, for example, x = 0, we will get:

y = -3*0 + 4 = 4

Then we also have the point (0, 4) (and the given one, (2, -2))

So we can draw these two points and then connect them with a line (just use a ruler and draw a line that passes through both points).

The left side of the two-column proof should be filled as follows:

Statements                                             Reasons_______________

32 = 2x + 4y; x = 2          ⇒                       Given

32 = 2(2) + 4y                ⇒                     Substitution Property

32 - 4 = 4 + 4y - 4        ⇒                   Subtraction Property of Equality

28/4 = 4y/4                  ⇒                  Division Property of Equality

7 = y, y = 7                    ⇒                  Symmetric Property of Equality

The division property of equality states that when both sides (left and right) of an algebraic expression or equation are divided by the same (common) real number that isn't equal to zero (0), the quotients would always remain equal.

The subtraction property of equality states that the two (2) sides of an algebraic expression or equation would still remain equal even when the same number has been subtracted from both sides of an equality.

In conclusion, it has been proven that y is equal to 7 by using the two-column proof.

1. The mathematical expression that can be used to determine the total cost of mailing a package weighing p pounds is f(Tc) = 20 + 3p.

2. Since Betty spent $56 to mail her package, the weight in pounds of the mail must be 12 pounds.

A mathematical expression is a statement containing numbers, variables, and an arithmetic operation.

By substitute values in formula for volume of cuboid we get;

x² + 12x – 220 = 0

What is mean by Volume?

Volume of cuboid is defined as the amount of space occupied by the sides of cuboid in three-dimensional space.

Given that;

A cuboid with a volume of 924 cm' has dimensions,

4 cm, (x + 1) cm and (x + 11) cm.

Since, Volume of cuboid = Length x width x height

After substitute we get;

Volume of cuboid = 4 × (x + 1) × (x + 11)

924 = 4 (x² + 11x + x + 11)

924 = 4 (x² + 12x + 11)

Divide 4 both side;

231 = x² + 12x + 11

x² + 12x + 11 - 231 = 0

x² + 12x - 220 = 0

Thus, By the formula of volume of cuboid we get;

x² + 12x - 220 = 0

6 bottles are needed.

The unitary technique involves first determining the value of a single unit,  followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

given:

2 tablets 3 times per day

so, total tablets = 6 tablets

Total days = 14

so, total tablets in 14 days = 14 x 6 = 96

and, tablets per bottle= 15

Then, the number of bottles required = 96 /15 =6.4

(a) The area of the triangle = 6 cm squares

(b) The area of the whole shape = 76 cm squares

The shape given is formed by a triangle and a rectangle.

First we need to find the area of the triangle.

Height of the triangle = 3 cm

Base of the triangle = 4 cm

Area of the triangle = 1/2 x base x height

                                 = 1/2 x 4 x 3

                                 = 6 cm squares

Area of the whole shape = Area of the triangle + Area of the rectangle

Length of the rectangle = 10 cm

Width of the rectangle = 7 cm

Area of the rectangle = length x width

                                    = 10 x 7

                                    = 70 cm squares

Therefore, area of the whole shape = 6 + 70

The table which represents the transformation of function f given by g(x) = 3f(x) is:

x                   - 3   - 1     1    3

f(x)                - 5   - 1     3    7

The length and width of the rectangular box are 13 ft and 6 ft respectively.

The length of the batter's box on a softball field is 1 ft more than twice the width.

The area of the batter's box is 78 ft².

The length and width of the rectangular batter's box can be found as follows:

Therefore,

area of a rectangle = lw

where

Therefore,

area of the rectangular box = 78 ft²

l = 1 + 2w

Hence,

78 = (1 + 2w)w

78 = w + 2w²

2w² + w - 78 = 0

Hence,
