Step-by-step explanation:

No of teachers in the school = 5

Salaries they make =40000 to 70000

When one of the five teachers reduce salary to 20000/- per year, median may or may not shift one number to the left

Mean will definitely decrease by difference/5 = 4000 dollars

Thus mean will defintely change by reduction of 4000 dollars.

Median has a chance to remain the same or may shift left side one item.

Given :-

To Find :-

Solution :-

Given expression to us is ,

[tex](9^{2} )^{-1/3}[/tex]

We know that ,

[tex] 9 = 3^2[/tex]

So our expression becomes ,

[tex]\{ (3^2)^2\}^{\frac{-1}{3}}[/tex]

And , [tex] (a^m)^n =a^{mn}[/tex] . Using this ,

[tex] (3^4)^{\frac{-1}{3}}[/tex]

Again using the same law ,

[tex] 3^{\frac{-4}{3}}[/tex]

We know that , [tex] a^{-m}=\frac{1}{a^m}[/tex] . Therefore ,

[tex] (3^{-4})^{\frac{1}{3}}[/tex]

[tex]\\\bigg( \dfrac{1}{3^4}\bigg)^{1/3}[/tex]

[tex]\\ \dfrac{1}{\sqrt[3]{3^4}}[/tex]

Simplify ,

[tex] \dfrac{1}{3\sqrt[3]{3}}[/tex]

This is the simplified expression.

Answer:

9.9 millimeters

Step-by-step explanation:

To find the perimeter of a square,

Equation: 4 • length = P

So in this case, we're just working backwards. To find the length, divide.

39.6/4 = 9.9

Answer:

9.9 mm

Step-by-step explanation:

let [tex]x[/tex] = length of one edge of the square

perimeter of a square = 4[tex]x[/tex]

⇒ 39.6 = 4[tex]x[/tex]

⇒ [tex]x[/tex] = 39.6 ÷ 4 = 9.9 mm

Answer:

p=10

Step-by-step explanation:

q = 4 +0.8p

Let q = 12

12  = 4 +0.8p

Subtract 4 from each side

12-4 = 4+.8p -4

8 = .8p

Divide each side by .8

8/.8 = .8p/.8

10 =p

Answer:

{y,x} = {-4,-2}

Expanation:

Solve by Substitution :

// Solve equation [1] for the variable  y

 [1]    y = 2x

// Plug this in for variable  y  in equation [2]

  [2]    -2•(2x) - 8x = 24

  [2]     - 12x = 24

// Solve equation [2] for the variable  x

  [2]    12x = - 24

  [2]    x = - 2

// By now we know this much :

   y = 2x

   x = -2

// Use the  x  value to solve for  y

   y = 2(-2) = -4

Answer:

B) all real values of x except x=5

Step-by-step explanation:

If [tex]f(x)=x^2-25[/tex] and [tex]g(x)=x-5[/tex], then [tex]\bigr(\frac{f}{g}\bigr)(x)=\frac{f(x)}{g(x)}=\frac{x^2-25}{x-5}=\frac{(x-5)(x+5)}{(x-5)}[/tex].

Given that [tex]x-5[/tex] exists in both the numerator and denominator, this creates a hole on the graph of the function where [tex]x=5[/tex] since [tex]5-5=0[/tex]all real values of x except x=5 is correct.

Answer: -1.51, or it could be 4.09 < 5.6 (Im sorry if I get it wrong I just wanted to help)

Step-by-step explanation:

The value of the subtraction is 1.51.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given numbers are 4.09 and 5.6. The value of 4.09 less than 5.6 will be calculated as:-

Subtraction = 5.6 - 4.09

Subtraction = 1.51

Therefore, the value of the subtraction is 1.51.

The surface area of the triangular prism, rounded to the nearest tenth is: 85.7 cm²

Surface area (SA) = bh + (s1 + s2 + s3)H

Given:

s1 = 6.8 cm

s2 = 5.1 cm

s3 = 8.5 cm

H = 2.5 cm

b = 6.8 cm

h = 5.1 cm

Plug in the values

Surface area of the triangular prism = 6.8 × 5.1 + (6.8 + 5.1 + 8.5)2.5

Surface area of the triangular prism = 85.7 cm²

Answer:

∠ ADC = 110°

Step-by-step explanation:

∠ CDE = 90° ( angle between perpendicular lines ) , then

∠ CDB + ∠ BDE = 90°

∠ CDB + 20° = 90° ( subtract 20° from both sides )

∠ CDB = 70°

∠ ADC and ∠ CDB are adjacent angles on a straight line and sum to 180° , so

∠ ADC + ∠ CDB = 180° , that is

∠ ADC + 70° = 180° ( subtract 70° from both sides )

∠ ADC = 110°

Volume of a figure is the measurement of space occupied by the figure. The volume of the specified sphere is given by Option B: 267. 95 m³

If the given sphere is of radius r units, then its volume is given as:

[tex]V= \dfrac{4}{3} \pi r^3 \: \rm unit^3[/tex]

For the given sphere, its diameter is 8 units, thus, its radius is half of its diameter and thus, of 4 units.

Thus, volume of specified sphere is obtained as:

[tex]V= \dfrac{4}{3} \pi r^3 \: \rm unit^3\\\\V = \dfrac{4}{3} \pi (4)^3 =\dfrac{256}{3} \times 3.14 \approx 267.95 \: m^3[/tex]

====================================================

Further explanation:

x+y = 80 is the total equation (ie the head count equation) since we assume each animal has 1 head, and there are 80 heads total.

That equation can be solved to y = 80-x after subtracting x from both sides.

The legs equation is 2x+4y = 248 because...

We're told there are 248 legs overall, so that's how we ended up with 2x+4y = 248

------------

Let's plug y = 80-x into the second equation and solve for x.

2x+4y = 248

2x+4( y ) = 248

2x+4( 80-x ) = 248

2x+320-4x = 248

-2x+320 = 248

-2x = 248-320

-2x = -72

x = -72/(-2)

x = 36

There are 36 ducks

Now use this x value to find y

y = 80-x

y = 80-36

y = 44

There are 44 cows.

------------

Check:

36 ducks + 44 cows = 80 animals total

36*2 + 44*4 = 72 + 176 = 248 legs total
