Answer:

Step-by-step explanation:

let number be x

CASE 1) when x>13

2(x-13) = 4

2x - 26 = 4

2x = 30

x = 15

CASE 2) when x<13

2(13 - x) = 4

26 - 2x  = 4

26 - 4 = 2x

22 = 2x

11 = x

Answer:

x-(-0.9)

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation::3*x+7*x-(9-18)=0

Solve::10x+9 = 0

Subtract 9 from both sides of the equation::10x = -9

Divide both sides of the equation by 10::x = -9/10 = -0.900

Answer:

Step-by-step explanation:

3x+7x=9-18

10x = -9

x = -9 / 10

x = -0.9

Answer:

x= 1.6 degrees

Step-by-step explanation:

to find the missing angle 180 degrees - 151 degrees

29° is the missing angle at the bottom ryt of the triangle.

all angles in triangle add upto 180°

so, 20x-3°+11x-1°+29°= 180°

31x=180°-25°

x= 1.6°

A polygon with three edges and three vertices is called a triangle.

x=1.6° is its value.

Based on the lengths of its sides, triangles can be categorized into one of three groups: Scalene. Isosceles. Equilateral.

The trigon, a 3-sided polygon, is sometimes (though not often) referred to as a triangle. Every triangle has three sides and three angles, some of which might be the same.

The triangle's angles are created by joining its three sides end to end at a single point. The sum of the three angles of the triangle is 180degrees.

To identify the omitted angle between 180 and 151 degrees

The triangle's bottom right corner lacks a 29° angle.

triangle's angles sum up to 180°

so, 20x-3°+11x-1°+29°= 180°

31x=180°-25°

x =1.6 degree

The  value  is [tex]E =19.6 [/tex]

Step-by-step explanation:

From the question we are told that

  The mean of Jo  cows is  [tex]\= x_1 = 1350[/tex]

  The standard deviation of Jo cow is  [tex]s_1 =  50[/tex]

  The mean of Val  cows is [tex]\= x_2  = 1420 [/tex]

   The standard deviation of Val  cows  is  [tex]s_2 =  50[/tex]

    The sample size for both Val  and  Jo  is  n = 25

Let assume that the level of significance is  [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the margin of error is mathematically represented as  

      [tex]E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }[/tex]

Hence margin of error for Jo is  

=>   [tex]E = 1.96 *  \frac{50}{\sqrt{25} }[/tex]

=>   [tex]E =19.6 [/tex]

Answer:

-1.8x² - 1.61x - 37.45 > 0

Step-by-step explanation:

Pattie's Produce charges $2.29 for a package of strawberries. On average, Pattie's Produce sells 95 packages of strawberries daily. They estimate that for each 20-cent increase in the cost of a package of strawberries, 9 less packages will be sold each day. Let x represent the number of 20-cent increases in the cost of a package of strawberries. Which inequality represents the values of x that would allow Pattie's Produce to have a daily revenue of at least $255 from selling the packages of strawberries?

Answer:

The cost of packaging 95 packages of strawberries is $2.29(95)=$217.55.

20-cent increase in the cost of a package of strawberries leads to 9 less packages to be sold. If x represent the number of 20-cent increases in the cost of a package of strawberries. the cost of packaging is:

Cost = (2.29 + 0.2x)(95 - 9x)

For a revenue of atleast $255:

(2.29 + 0.2x)(95 - 9x) > 255

217.55 - 20.61x + 19x - 1.8x² > 255

-1.8x² - 1.61x + 217.55 > 255

-1.8x² - 1.61x + 217.55 - 255 > 0

-1.8x² - 1.61x - 37.45 > 0

Answer:

384

Step-by-step explanation:

No. of students in the club last year = 320

No. of students in the club this year increased by 20%

To find the actual increase, 20% is multiplied by the number of students in the club last year which is 320 and to find the number of students in the club this year add the answer to 320 (the number of students in the club last year)

That is,

= 20% * 320

= 20/100 * 320

= 64

Finding the number of students in the club this year

320 + 64 = 384 students

NOTE : Increase means addition that is why the number of students in the club last year is added to the actual increase
