Answer:

let cp = x

now ,

sp= x-5%ofx

212= 4x/5

x=265$

Answer 2

Answer: Cost price 265$

Step-by-step explanation: Loss% = 20.

The length of a rectangle is three times the width. The perimeter is 96 cm. Find the length and width of the rectangle.

Answers

Answer:

Length = 36cm

Width = 12 cm

Step-by-step explanation:

Perimeter = all the sides added up.

Perimeter of a rectangle = L + L + W + W OR  2L + 2W

We are given that the length = 3 times the width. So L = 3W

P = 2L + 2W

96 = 2 (3W) + 2W

96 = 6W +2W

96 = 8W (divide both sides by 8)

W = 12 cm

To find the length-  we know the length is 3 times the width.

So L = 3 x 12 = 36 cm

What is the slope of the line y = 3?

Answers

Answer:

m = 0

Step-by-step explanation:

Using the slope intercept form. The slop is 0

Answer: m = 0

Explanation: The equation y = 3 can be thought of as y = 0x + 3.

So our line has a slope of 0 and a y-intercept of 3.

When the equation of any line reads "y = a number",

it's graph will always be a flat or horizontal line.

Whenever we have a horizontal line, the slope is always 0

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

All the different natural numbers that each leave a remainder of 2 when divided into 83.

Since, The remainder is 2

So, The value of number = 83 - 2

                                       = 81

Now, All the factors of 81 are,

⇒ 3, 6, 9, 81

Thus, All the natural number which divides the 83 and leave the remainder 2 are,

⇒ 3, 6, 9, 81

Esta pregunta esta incompleta

Pregunta completa

El señor Juan tiene una tienda de abarrotes y sus ventas son al mayoreo y al menudeo. La semana pasada recibió dos toneladas de azúcar en 40 sacos de 50 kg cada uno.

Con el azúcar de un saco empacó bolsas de 250 cada una.¿cuantas bolsas en paco​

Answer:

200 bolsas.

Step-by-step explanation:

Se nos dice en la pregunta,

La semana pasada recibió dos toneladas de azúcar en 40 bolsas de 50 kg cada una.

Esto significa

1 bolsa = 50 kg de azúcar.

1 kg = 1000 gramos

50 kg = 50 × 1000 gramos

= 50000 gramos

Por tanto, 1 bolsa contiene = 50000 gramos de azúcar.

A partir de la pregunta anterior, se nos pregunta cuántas bolsas de azúcar obtendría si cada bolsa contuviera 250 gramos.

Por lo tanto:

50000/250 gramos

= 200 bolsas.

Por lo tanto, obtendría 200 bolsas.

We have to given that,

To find a number which is 175% of 56.

Let us assume that,

A number which is 175% of 56 is, x

Hence, We can write as,

x = 175% of 56

x = 175/100 × 56

x = 1.75 × 56

x = 98

Find a polynomial function of degree 3 with real coefficients that has the given zeros.
- 2, 3, -4

Answers

Polynomial functions' standard form is f(x)=ax^n+bx^n-1...+k

However, polynomials can also be written in intercept form

f(x)=(x-x1)(x-x2)(x-x3)...(x-xn) for roots/zeros x1,x2,x3,...,xn

With the three numbers that you have -2, 3, -4 you can write function

f(x)=(x-(-2))(x-3)(x-(-4))

Then you can simplify and distribute

f(x)=(x+2)(x-3)(x+4)

f(x)=(x^2-x-6)(x+4)

f(x)=x^3+3x^2-10x-24

A company has two machines MI and M2. MI produces 60% of its product and M2 produces 40% of its product. M1 produces 5% defective units and M2 produces 4% defective units. A unit is selected at random from the whole product. A) Find the probability that it is defective. B) What is the probability that it was manufactured by machine M2​

Answers

Step-by-step explanation:

Consider the problem

Let, E 1 and E 2

​  be the respective events of items produced by machine A and B.

And let x be the event that the produced item was found to be defective.

Therefore,

Probability of items produced by machine A,P (E 1)=60%= 53

Probability of items produced by machine B,P (E 2)=40%= 52

And,

Probability that machine A produced defective items, P( E 1 x)=2%= 1002

Probability that machine B produced defective items, P( E 2 x)=1%= 1001

So, the probability that randomly selected items was from machine A is given by P( x E 1)

Now, Apply Bayes' Theorem

P( x E 1)= P(E 1)P( E 1x )+P(E 2)P( E 2x)P(E 1)P( E 1x)= 52× 1001 + 5

3× 1002

53× 100

2= 2+5

6= 11

6

Hence, the required probability of machine A is  

11

6

The required answers are,

A.) The probability that the unit is defective is 0.046

B.) The probability that it was manufactured by machine M2​ is 0.4

What is probability?

Probability is the extent to which an event is likely to occur, measured by the ratio of the favorable cases to the whole number of cases.

Now given that,

Product produced by machine M1 = 60%

⇒ P(M1) = 60% = 0.6

Defective units = 5%

⇒ P(D1) = 5% = 0.05

Product produced by machine M2 = 40%

⇒ P(M2) = 40% = 0.4

Defective units = 4%

⇒ P(D2) = 4% = 0.04

Now, a unit is selected at random from the whole product

So, probability that it is defective is given as,

P(D) = P(D|M1) * P(D1) + P(D|M2) * P(D2)

⇒ P(M1|M2) = (0.6 X 0.05) + (0.4 X 0.04)

⇒ P(M1|M2) = 0.03 + 0.016

⇒ P(M1|M2) = 0.046

And probability that it was produced on the first machine(M2).

P(M2|D1) = P(M2∩D1) / P(D1)

⇒ P(M2|D) = (0.4 X 0.04)/0.04

⇒ P(M2|D) = 0.016 / 0.04

⇒ P(M2|D) = 0.4

Thus, the required answers are,

A.) The probability that the unit is defective is 0.046

B.) The probability that it was manufactured by machine M2​ is 0.4

c. -1(1)/(2),(1)/(4),2
b. 1(1)/(2),(1)/(4),-2
d. -1(1)/(2),-(1)/(4),2

Answers

Answer:

Step-by-step explanation:

Rational zeros of f(x) = 8x³-6x²-23x +6 is equals to [tex]2, \frac{-3}{2} , \frac{1}{4}[/tex].

What are rational zeros?

"A rational zero of a polynomial P(x) is defined as when the variable x = p/q  and P (p/q) = 0 where p and q are any integers."

According to the question,

Given,

f(x) = 8x³-6x²-23x +6

Factor of 6 'p' =±1, ±2, ±3, ±6

Factor of 8 'q' = ±1 , ±2, ±4 , ±8

Using trial and error method x=2 is a common factor

Substitute x=2 in f(x) we get,

f(2) = 8(2)³ -6(2)² -23(2) +6

     = 64-24-46+6

      =0

(x-2) is a factor of f(x).

Divide f(x) by (x-2)

[tex]\frac{8x^{3}-6x^{2} -23x+6 }{(x-2)}[/tex]

= 8x²+10x-3

Factorize it we get,

8x²+12x-2x-3

= 4x(2x+3) - 1(2x+3)

= (4x-1)(2x+3)

For rational zeros ,Substitute f(x=(p/q)) =0

x-2=0

x=2

2x+3=0

x= -3/2

     = [tex]-1\frac{1}{2}[/tex]

4x-1 =0

x=1/4

Hence, Option (C) is the correct answer.

Plant food is indeed dung or a mix of nitrates that are also given to soil to make it fruitful. Plant fertilizers are available in a variety of formats in the market, including water-soluble plant fertilizer, sustained-release crop fertilizer, and many others. Natural organic food is the best option for fertilizing.

Feeding the plants on a normal basis ensures optimum growth, the production of attractive blossoms and fruit, and the developing resistance to harsh weather and disease.As only one amount of plant-based foods remains every day, this connection is not a function.
