How many even numbers can be formed from the digits 1,2 3 4 5?

The cost price of an article is Rs.600 and the profit of dealer is Rs.200

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given;

An article marked at Rs.800 sold at a discount of 10%.

That means,

selling price = 800 - 10% 0f 800

                 =  800 - (10 x 800 / 100)

                 = 800 - 80

                 = 720

The dealer makes a profit of 20% means is selling the article at 120%.

120%=720

1%=6

Hence, 100% = 600

Thus, the cost price of article = 600

Profit= SP-CP = 800-600 = 200

Therefore, Rs.600 is the cost price and the profit is Rs.200

Answer: Carrots cost(s) the most per pound

Step-by-step explanation:

Answer:

Below

Step-by-step explanation:

To find the number of games g that the team could lose and still be eligible for the playoffs, we can write the inequality:

g / 18 ≤ 40%

g / 18 ≤ 0.4

g ≤ 7.2

We can round down to 7 to get the maximum number of games the team could lose and still be eligible for the playoffs.

If the baseball team loses 8 of its remaining games, they will not advance to the playoffs. This is because 8 is greater than the maximum number of games they could lose and still be eligible for the playoffs, which is 7.

Difference in miles travelled by Bus X and Y is  12.8 miles in distance

Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is travelling along a route. In other words, velocity is a vector, whereas speed is a scalar number.

The direction of a body or object's movement is defined by its velocity. In its basic form, speed is a scalar number. In essence, velocity is a vector quantity. It is the speed at which distance changes. It is the displacement change rate.

The size or extent of the displacement between two points is referred to as distance. Keep in mind that the distance between two points and the distance traveled between them are not the same. The length of the entire journey taken to go from one point to another is the distance traveled. Travel distance is not a vector.

Bus X travels 40 miles in 1 hour

Distance travelled in 2 hrs = 40*2 = 80 miles

Bus Y travels 60 miles per hour

Distance travelled in 1.12 hrs = 60*1.12 = 67.2 miles

Difference in miles travelled by Bus X and Y is = 80 - 67.2 = 12.8 miles

Answer:

To find the solutions of the equation x^2+4x+3=0, you can use the quadratic formula:

x = (-b +/- sqrt(b^2 - 4ac)) / (2a)

where a, b, and c are the coefficients of the quadratic equation. In this case, a = 1, b = 4, and c = 3. Plugging these values into the formula gives:

x = (-4 +/- sqrt(16 - 413)) / (2*1)

x = (-4 +/- sqrt(4)) / 2

x = (-4 +/- 2) / 2

This means the two solutions for x are (-4 - 2) / 2 = -3 and (-4 + 2) / 2 = -1.

So the biggest and lowest numbers you can get with the number x^2+4x+3=0 are -3 and -1, respectively.

Answer: The biggest number is  x= -1 and

                   the lowest number is    x= -3 .

Step-by-step explanation: Solution

or, x^2+4x+3=0

or, x^2+ ( 3+1 )x+3=0

or, x^2+3x + x +3=0

or, x (x + 3)+ 1(x + 3)=0

or, (x + 3) (x + 1)=0

Either,

        (x + 3)= 0  ,    (x + 1)= 0

     or, x= -3       ,    x= -1

Therefore, The biggest number is  x= -1 and

Using the same-side exterior angles theorem, the value of y is: 92°.

The same-side exterior angles theorem states that if two lines are cut by a transversal, and the alternate interior angles are congruent (equal in measure), then the same-side exterior angles are supplementary (add up to 180 degrees).

The image shows two angles that are same-side interior angles, which are (x + 1) and (x - 3) degrees. Therefore, their sum would be equal to 180 degrees. This means that:

(x + 1) + (x - 3) = 180 [based on the same-side exterior angles theorem]

x + 1 + x - 3 = 180

2x - 2 = 180

2x = 180 + 2

2x = 182

2x/2 = 182/2

x = 91

Thus, based on the alternate interior angles, we also have:

x + 1 = y

WXYZ can be a parallelogram with one pair of sides measuring 15 mm and the other pair measuring 9 mm.

A quadrilateral is defined as a two-dimensional shape with four sides, four vertices, and four angles. There are two main types: concave and convex. There are also various subcategories of convex quadrilaterals, such as trapezoids, parallelograms, rectangles, rhombi, and squares.

If quadrilateral WXYZ is a parallelogram, the opposite sides will be equal, in length from which the value of x will satisfy the two equations.

Given,

WXYZ can be a parallelogram with one pair of sides measuring 15 mm and the other pair measuring 9 mm.

The length of the opposite sides of a parallelogram are equal, which gives;

2x - 5 = x + 2

2x - x = 2 + 5

x = 7

Similarly, we have;

x + 8 = 15

x = 15 - 8 = 7

The lengths of the opposite sides are therefore;

2·x - 5 = 2 × 7 - 5 = 9 and x + 8 = 15

Therefore the answer is d) WXYZ cannot be a parallelogram because the value of x that makes one pair of sides congruent does not make the other pair of sides congruent.

A parallelogram is a quadrilateral with two pairs of parallel sides. This means that the sides of the quadrilateral are arranged such that opposite sides are parallel and have the same length. In other words, if you draw a line through one pair of opposite sides, the other pair of opposite sides will also be parallel to that line and have the same length.

So, to determine if a quadrilateral can be a parallelogram, we need to check if it has two pairs of parallel and congruent sides. It does not matter what the lengths of the sides are.

In this case, option (d) is the correct answer because it states that one pair of sides can be congruent, but the other pair of sides is not congruent, which means that the quadrilateral cannot be a parallelogram

The cost of the 12 units sold is, $224 - $144 = $80

Using the FIFO periodic inventory method, the cost of the 12 units that are sold is $120. This is because the first 12 units sold were the ones that were purchased on February 3 for $12 each. The total cost of these units is 12 units * $12/unit = $12*12=144. The remaining 8 units in the inventory were purchased on February 1 for $10 each, for a total cost of 8 units * $10/unit = $8*10=80. The total cost of the inventory is therefore $144 + $80 = $224. The cost of the 12 units sold is, therefore, $224 - $144 =$80.

Rounded to the nearest ten-thousandth, the solution is x of the logarithmic equation is 2.000.

To solve this equation, we can begin by isolating the logarithmic expression on one side of the equation. To do this, we can divide both sides of the equation by 3:

3 log 2x / 3 = 4 / 3

This simplifies to:

log 2x = 4/3

Now, we can use the property of logarithms that states that "log [tex]a^b[/tex] = b × log a" to rewrite the logarithmic expression on the left side of the equation:

log 2x = 4/3

log [tex]2^{(4/3)}[/tex] = 4/3

4/3 × log 2 = 4/3

This simplifies to:

log 2 = 1

D. 15211 weekly pounds per skilled worker

E. 4347 weekly pounds per unskilled worker

Partial derivative is the derivative of a function that has several independent variables, to one of the independent variables by holding the other independent variables as constants.

Now we take a look at the given problem. The production function is:

z = f(x, y) = 13000x + 3500y + 7x²y - 13x³, where

z = the weekly number of pounds of acetate fiber

x = the number of skilled workers at the plant

y = the number of unskilled workers at the plant

Weekly fiber that can be produced with 11 skilled workers and 45 unskilled workers:

z = f(x, y) = 13000x + 3500y + 7x²y - 13x³

  f(11,45) = 13000*11 + 3500*45 + 7*11²*45 - 13*11³

              = 143000 + 157500 + 7*121*45 - 13*1331

              = 143000 + 157500 + 38115 - 17,303
