The quotient of 550six and 50six​ is obtained by the calculation to be   11 six

We know that the result that we obtain after we have carried out a division operation is called a quotient. In this case, we have been required to carry out the operation of division in base six.

We could start by converting the both values to base 10 as follows;

(5 * 6^2) + (5 * 6^1) + (0 * 6^0) = 180 + 30 + 0 = 210 ten

(5 * 6^1) + (0 * 6^0) = 30 + 0 = 30 ten

Then we carry out the division in base ten; 210 ten/30 ten = 7 ten

We convert back to base six to obtain 11 six

What is inequality ?

inequality, When two numbers or algebraic expressions are stated to be greater than, greater than or equal to, less than, or less than or equal to each other in order. Inequalities can be stated as either statements of fact in the form of theorems, which are solved using methods similar to those used to solve equations, or as questions. For instance, the triangle inequality states that the length of the remaining side is greater than or equal to the sum of the lengths of any two sides of a triangle. Many of these inequalities, including the Cauchy-Schwarz inequality, are used in the proofs of many of mathematical analysis' most significant theorems.

Answer:

35.224137931

Step-by-step explanation:

1266.66/35.96=35.224137931

Without the actual data for the average prices of gold in 2010 and 1970, I cannot provide the exact quotient. However, if we assume that we have the data, we can calculate the quotient by dividing the average price of gold in 2010 by the average price of gold in 1970. The resulting quotient would indicate how many times more expensive gold was in 2010 compared to 1970.

For example, if the average price of gold in 2010 was $1,500 per ounce and the average price in 1970 was $35 per ounce, then the quotient would be:

$1,500 / $35 = 42.86

This means that the average price of gold in 2010 was 42.86 times more expensive than the average price in 1970.

It is important to note that the actual quotient will depend on the actual data for the average prices of gold in 2010 and 1970.

The answer is

(a) the fixed cost when zero items are produced is $500 .

(b) cost for making 25 items is $750  .

(c) the domain and range of cost function is [0,100] and [500,1500] respectively  .

It the question ,

it is given that

the cost function is C(x)=10x+500  

Part(a)

to determine the fixed cost when 0 items are produced

Since 0 items are produced , we substitute the value x=0 in the cost function , we get

C(0)=10(0)+500

= 500

the fixed cost is $500.

Part(b)

to find the cost of making 25 items , we substitute x=25

On substituting the x=25 , we get

C(25)=10(25)+500

= 250+500

=750

the cost for 25 items is $750.

Part(c)

to find the domain of the cost function C(x)

Given that the maximum cost allowed is 1500

So, 1500=10x+500

10x=1500-500

10x=1000

x=100

So minimum 0 items and maximum 100 items can be produced ,

hence the Domain is [0,100]

to find the range

substituting x=0, the cost = $500

on substituting x=100 , the cost = $1500

the Range is [500,1500]

Therefore , (a) the fixed cost when zero items are produced is $500 .

(b) cost for making 25 items is $750  .

(c) the domain and range of cost function is [0,100] and [500,1500] respectively  .

The given question is incomplete , the complete question is

The cost in dollars of making x items is given by C(x)=10x+500. The fixed cost is determined when zero items are produced.

A brief definition of a triangle according to Euclidean geometry is shown below:

Closed figure consisting in three non-colinear, all of them coplanar, points named vertices and three line segments associated to each pair of points named sides.

To understand what a triangle is, we need to understand some basic concepts of the Euclidean geometry. There are three undefined terms, that is, fundamental elements that cannot be defined but are described in terms of its attributes. Those terms are point, line and plane. The atributes of each element are described below:

A line can be formed by knowing the location of two distinct points on a plane. Lines can be continuous lines (endless), line segments (lines with finite length) or semirrays (lines with only one endpoint).

Let suppose that we have three points not collinear to each other, then we construct line segments for each pair of collinear points. Then, we create a triangle, whose brief definition is shown below:

and b is the y-intercept

Rewriting the equation :

The equation will be y = 1/2 x + 4

the slope is m = 1/2

nd the y-intercept is b = 4

Note that parallel lines have the same slope.

So the slope of parallel line is m = 1/2

So the slope of perpendicular line to this line is m = -2

Equation of parallel line :

we have :

Let's say the line passes at the origin (0, 0)

If a line passes thru the origin, the y-intercept is always b = 0

Therefore, the equation of parallel line is y = 1/2 x
