What is the equation answer of 63.4 divided by 20?

The maximum profit of manufacturing company is  = $3150

If an equation is in ax + b = c and there is only one variable in the equation then it is called linear equation in one variable. a , b , c are real number and a is not equal to 0.

To maximize  profit, we must determine the number of trick  and slalom skis to produce each day, subject to the constraints of available labor hours.

Let x be the number of  skis and y be the number of slalom skis produced per day.

 The objective function to be maximized is:

Profit = 60x50 a

With the following limitations:

Production hours: 9x 6 a ≤ 432

Final hours: x y ≤ 63

Non-negativity constraints: x ≥ 0, y ≥ 0

We can solve this linear programming problem using graphical or algebraic methods. Here we  use algebraic methods:

From the second limit, we get y ≤ 63 - x.

If this inequality is replaced by the first limit, we get:

9 x 6 (63 - x) ≤ 432

3x ≤ 54

x ≤ 18

This means that the maximum production rate is 18 pieces per day. Replacing x = 18 by the inequality y ≤ 63 - x, we get:

y ≤ 63 – 18 = 45

So the maximum production is 45 slalom skis  per day.

 To verify that this is the correct solution, we need to ensure that it satisfies the non-negativity constraints:

x ≥ 0 and y ≥ 0 are already given in the assignment statement.  

Therefore, the maximum profit is:

Profit = 60(18) 50(45) = $3150

The biggest profit is when 18 trick skis and 45 slalom skis are made per day.

Answer:

mp = 37500

Step-by-step explanation:

let mp be x

D.A = 20×x/100

= 20x/100

=x/5

price after discount = mp - DA

= x-x/5 = 4x/5

VAT= 15%of 4x/5

= 15/100 × 4x/5

= 60x/500

sp with vat= 4x/5 +60x/500

= 460x/500

sp with vat - sp after discount = 4500

460x/500-4x/5=4500

60x= 4500×500

x= 37500

The answer of the given question based on graph is Part A: the unit rate of square feet painted per minute is 1.125, so the ordered pair that displays this unit rate is (1, 1.125) and Part B:  the points that lie on the line are (3.5,3.9375), (4,5), and (32,36).

Slope refers to the steepness of a line or a surface. More specifically, slope is defined as the ratio of the vertical change (rise) between two points to the horizontal change (run) between the same two points on a line or a surface. In other words, slope measures how much a line or a surface rises or falls as it moves horizontally.

Since the relationship between the minutes worked and the square feet painted is proportional, we can use the slope-intercept form of a linear equation to represent it:

To find the equation of the line, we can use the given point (16,18) and the fact that the relationship is proportional. If we let the unit rate be r (in square feet per minute), then we have:

18 = r(16)

r = 18/16

r = 1.125

So the equation of the line is:

y = 1.125x

Part A: The unit rate of square feet painted per minute is 1.125, so the ordered pair that displays this unit rate is (1, 1.125), since the slope represents the unit rate in a proportional relationship.

Part B: To determine which of the points lie on the line, we can plug in the x-values into the equation y = 1.125x and see if the resulting y-values match.

(y - 18) / (x - 16) = slope

Using the slope calculated above, we can simplify this equation to:

y = 1.125(x - 16) + 18

Now, we can plug in the x and y values for each point and check if they satisfy this equation:

(2,2.5): 2.5 = 1.125(2 - 16) + 18, not on the line

(3.5,3.9375): 3.9375 = 1.125(3.5 - 16) + 18, on the line

(4,5): 5 = 1.125(4 - 16) + 18, on the line

(32,36): 36 = 1.125(32 - 16) + 18, on the line

(10,11.5): 11.5 = 1.125(10 - 16) + 18, not on the line

(0,0): 0 = 1.125(0 - 16) + 18, not on the line

Therefore, the points that lie on the line are (3.5,3.9375), (4,5), and (32,36).

The test statistic is less than the critical value, so, we reject the null hypothesis and conclude that there is a statistically significant difference between the population means.

A two-sample t-test is used to compare the means of two samples to determine if there is a statistically significant difference between them.

To answer this question, we must conduct a two-sample t-test.

In this case, the null hypothesis is that there is no difference between the population means, and the alternative hypothesis is that there is a difference between the population means.

The test statistic is calculated using the following formula:

t = (x₁ - x₂) / (√((s₁²/n₁) + (s₂²/n₂)))

Where x₁ and x₂ are the sample means of the two samples, s₁ and s₂ are the sample standard deviations, and n₁ and n₂ are the sample sizes.

Plugging in the sample data, we get:

t = (22 - 26) / (√((4.3²/11) + (4.4²/8)))

= -1.98

The critical value of t for a two-tailed test at the 0.01 significance level is 2.58.

Since the test statistic is less than the critical value, we reject the null hypothesis and conclude that there is a statistically significant difference between the population means.

Answer: Let's assume that the width of the rectangular room is "x" meters. Then, according to the problem, the length of the room is 2 times the width, which means the length is "2x" meters.

The perimeter of the room is the sum of all four sides, so we can write:

Perimeter = 2 × (length + width)

Substituting the values, we get:

48 = 2 × (2x + x)

Simplifying the expression, we get:

48 = 2 × 3x

Dividing both sides by 2, we get:

24 = 3x

Solving for "x", we get:

x = 8

Therefore, the width of the room is 8 meters and the length is 2 times the width, which is 2 × 8 = 16 meters.

So the dimensions of the room are 8 meters by 16 meters.

Step-by-step explanation:

The width of the added strip is 10 meters.

What is Area?

Area is a measure of the amount of surface enclosed by a two-dimensional shape or figure. It is usually expressed in square units, such as square meters or square inches, and is calculated by multiplying the length of a side or a diameter by itself or by using an appropriate formula for the shape.

If the area of the skating rink is doubled by adding a strip of equal width along one side and another strip at one end, then the new dimensions of the skating rink would be

=>  (30 + x) × (20 + x),

where x is the width of the added strip.

According to the problem, the new area of the skating rink is double the original area, so we can set up the following equation:

=> (30 + x)(20 + x) = 2(30 ×20)

Expanding the left-hand side and simplifying, we get:

=> 600 + 50x + x² = 1200

Rearranging and solving for x, we get:

=> x² + 50x - 600 = 0

Factoring the left-hand side, we get:

=> (x + 60)(x - 10) = 0

Therefore, the possible values for x are x = -60 and x = 10. Since the width of the strip cannot be negative, we reject x = -60 and conclude that the width of the added strip is 10 meters.

The value of y for the given quadrilateral is 5.

A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees.

The Latin words quadra, which means four, and latus, which means sides, are combined to form the English term quadrilateral. A quadrilateral does not always have to have equal lengths on each of its four sides. As a result, depending on the sides and angles, we might have several sorts of quadrilaterals.

We know that the opposite sides of the quadrilateral have a sum of 180 degrees.

Thus,

23y + 13y = 180

36y = 180
