The value of the variable r in 6r+ r- 4 will be 4/7.

Given,

To solve the polynomial,

6r + r- 4,

and find the value of the variable r,

we have to convert the polynomial in to a quadratic equation by equating it with 0, or, in other words, making the polynomial equal to zero.

So, the quadratic equation will be,

6r + r- 4 = 0

=> (6r+ r) -4 =0

=> 7r -4 = 0

=> 7r = 4

=> r = 4/7.

Thus, the value of the variable r in the polynomial 6r + r -4 will be 4/7.

-> x=-7.5

Answer:

-18 + -5

Step-by-step explanation:

Because -18 - 5 is an inverse equation, that means that we are doing one equation that looks like something it usually doesn't. When subtracting a negative and a positive in that order, the result will be the sign of the greater value(-18), so the result will be negative. Subtracting a big number that's a negative by a smaller number that's a positive is the same as adding the same numbers together as if they are both negatives. E.g, -4 - 2 = -4 + -2.

Answer:

Rs 80,0000 and Rs 100,000

Step-by-step explanation:

sum the parts of the ratio, 4 + 5 = 9 parts

divide the amount by 9 to find the value of one part.

Rs 1,80,000 ÷ 9 = Rs 20,000 , then

4 parts = 4 × Rs 20,000 = Rs 80,000 ← amount son receives

5 parts = 5 × Rs 20,000 = Rs 100,000 ← amount daughter receives

The sum obtained by the son is Rs. 80,000 and the daughter is Rs. 1,00,000.

Mr. Karki divided Rs. 1,80,000 in a ratio of 4:5 between his son and daughter.

Let the common multiple be x

∴ The son obtained Rs. 4x        --------1

And daughter obtained Rs. 5x        --------2

As the total sum is Rs. 1,80,000

∴ 4x + 5x = 180000

9x = 180000

x = 180000/9

∴ x = Rs. 20000

Putting the value of x in 1 and 2 we get,

The sum obtained by son = 4x = 4*20000 = Rs. 80000

And the sum obtained by daughter = 5x = 5*20000 = Rs. 100000

Thus, the son obtained Rs. 80,000 while the daughter obtained Rs. 1,00,000 which is in the ratio of 4:5.

According to the solving the area of the square is 68.0625.

As is common knowledge, a square is a four-sided, two-dimensional figure. It is also referred to as a quadrilateral. The total quantity of unit squares forming a square is referred to as the square's area. In other words, it is described as the area that the square takes up.

The box formed after cutting the square from each corner will have the dimensions as,

length = 104 - 2x, width = 39 - 2x, height = x.

∴ volume of the box = length × width × height

∴ v = (104 - 2x)(39 - 2x)(x) -----(i)

∴ v = (104 - 2x) (39x - 2[tex]x^{2}[/tex])

∴ v = 104(39x - 2[tex]x^{2}[/tex]) -2x(39x - 2[tex]x^{2}[/tex])

∴ v = 4056x - 208[tex]x^{2}[/tex] - 78[tex]x^{2}[/tex] + 4[tex]x^{3}[/tex]

∴ v = 4[tex]x^{3}[/tex] - 286[tex]x^{2}[/tex]  + 4056x

let f(x) =  4[tex]x^{3}[/tex] - 286[tex]x^{2}[/tex]  + 4056x  -----(ii)

To, find x for which f(x) is maximum,

⇒we should apply second derivative test ,

According to this test, first we should find critical points at which f'(x) = 0.

then if f''(x) < 0 for that critical point then f(x) is maximum at that critical point.

∴ let us consider, f'(x) = 0.

now, f(x) =  4[tex]x^{3}[/tex] - 286[tex]x^{2}[/tex]  + 4056x

⇒ f'(x) = 12[tex]x^{2}[/tex] - 572x + 4056.  -----(iii)

⇒ f'(x) = 4(3[tex]x^{2}[/tex] - 143x + 1014)

⇒ f'(x) = 0.

⇒  f'(x) = 4(3[tex]x^{2}[/tex] - 143x + 1014) = 0

⇒ x = (-b ± [tex]\sqrt{b^{2} - 4ac }[/tex])/2a    ; where a = 3, b = -143, c = 1014.

∴ x = (-(-143) ± [tex]\sqrt{(-143)^{2} -4(3)(1014)}[/tex])/2×3

∴ x = (143 ± [tex]\sqrt{8281}[/tex])/6.

∴ x = [tex]\frac{143 + 91}{6}[/tex]  , x = [tex]\frac{143 - 91}{6}[/tex]

⇒ x = 39, 8.25

the square of length 8.25 inch should be cut from each side to det contained with the maximum volume.

Area of the square is = [tex]x^{2}[/tex] = [tex]8.25^{2}[/tex]

Answer:

(a) $2.40

(b) Chips: 4/7

Drink: 3/7

(c) $9.60

Step-by-step explanation:

Polly buys a drink at a convenience store for $1. 80. She also buys a bag of chips.

(a) The ratio of the cost of the chips to the cost of the water is 4:3. Find the cost of the chips.

chips : water = 4 : 3

chips/water = 4/3

c/1.8 = 4/3

3c = 1.8 × 4

c = 0.6 × 4

c = 2.4

$2.40

(b) Polly has $6 to spend. Work out the total amount she spends on a drink and chips as a fraction of the $6. Give your answer in its lowest terms.

4 + 3 = 7

Chips: 4/7

Drink: 3/7

(c) The $6 is 37. 5% less than the amount Polly had to spend last week. Calculate the amount she had last week.

Last week it was 100%.

This week it is 37.5% less.

100% - 37.5% = 62.5%

This week, it is 62.5% of last week.

Let x = last week's amount.

62.5% of (last week's amount) = $6

62.5% × x = 6

0.625x = 6

Divide both sides by 0.625

x = 6/0.625

x = 9.6

Applying the definition of angle bisector, the value of x is: x = 3.

An angle bisector can be defined as a ray or line that divides an angle into two parts that are congruent or equal to each other in measure.

Since TR is the angle bisector that bisects angle ATS, it implies that angle ATS is divided into equal parts.

Given the following:

Measure of angle RTS = (17x - 5)°

Measure of angle ATS = (28x + 8)°

Therefore:

Measure of angle ATS = 2(measure of angle RTS) [definition of angle bisector]

Substitute

28x + 8 = 2(17x - 5)°

28x + 8 = 34x - 10

Combine like terms

28x - 34x = -8 - 10

-6x = -18

Divide both sides by -6

-6x/-6 = -18/-6

x = 3

Perimeter of the parallelogram is 20 units.

According to question,

3 + x = 2a - 4

     x = 2a - 4 - 3

    x = 2a - 7

Diagonals in a parallelogram bisects each other.

Therefore, 2a - 7 = 3

                       2a = 3 + 7

                       2a = 10

                          a = 10/2

                          a = 5

a - 1 = 4b - 6

5 - 1 = 4b - 6

    4 = 4b - 6

  4b = 4 + 6

   4b = 10

     b = 10/4

     b = 5/2

Opposite sides of a parallelogram are equal.

Therefore, c - 2 = 2b

                  c - 2 = 2(5/2)

                  c - 2 = 5

                       c = 5 + 2

Sides of parallelogram,

Side 1 = 12 - c

          = 12 - 7

          = 5

Side 2 = c - 2

           = 7 - 2

Perimeter of parallelogram = 2(length of side 1 + length of side 2)

                                             = 2(5 + 5)

                                             = 2 * 10

A p-value calculates the likelihood of getting the outcomes that were observed, presuming that the null hypothesis is correct. The statistical significance of the difference that was found increases with decreasing p-value. Statistical significance is commonly defined as a p-value of 0.05 or less. The sample data, test type, and sampling distribution of the test statistic under the null hypothesis are used to determine the p-value (lower-tailed test, upper-tailed test, or two-sided test).

Given,

Cook-it rice cooker has a mean time before failure of 38 months with a standard deviation of 4 months, and the failure times are normally distributed.

The 7th percentile, or X when Z has a p-value of 0.08, or X when Z = 0.4720, should serve as the warranty period.

Z = X - Mean/ standard deviation

Answer:

y = (2/3)y - 2

Step-by-step explanation:

Linear equations of the form y=mx+b, describe the slope, m, and the y-intercept, b (the value of y when x=0).  

Line K

y = -(3/2)x + 1 tells us that it has a slope of -(3/2) and crosses the y axis (x=0) at y = 1.  

Perpendicular Lines

Perpendicular lines have a useful property in that they have a slope that is the "negative inverse" of the line they are perpendicular to.  If, for example, we were ever asked  what is the slope of a line perpendicular to Line L (yes, it happens), we could, with minimal effort, respond "It is the negative inverse of -(3/2)," which is a slope of (2/3).

Line L

We just accidently answered a key question when we found the negative inverse of the slope for Line K, (2/3).  That will be the slope of Line L that will make it perpendicular to Line K.

Line L will have the form y = (2/3)x + b

This line will be perpendicular to Line K, no matter the value of b.  But we want a perpendicular line that goes through point (6,2), so we need to find a value of b that will force it to go through that point.

The role b has in our equation is simply moving it up or down.  If b were 0, the line will go through the origin (0,0).  If b were 5, it would interect the y axis at 5 (0,5).  We could draw a graph and get a pretty good idea what b would have to be for the line to go throgh (6,2), but most prefer the easier route:  Use the (x,y) value in the above equation and solve for b.  Its easy, and works great:

   y = (2/3)x + b for (6,2)

  2 = (2/3)(6) + b

   b = 2 - (2/3)*(6)

   b = 2 - 4

    b = -2

The equation for Line L is thus:  y = (2/3)y - 2
