Answer:

$10 each

Step-by-step explanation:

There are four friends

Friend 1 = $15

Friend 2 = $20

Friend 3 = $40

Friend 4 = unknown

NOTE;

You didn't provide the earnings of the fourth friend is not given BUT the question can be solved without knowing the earnings of the fourth friend

The four friends decide to split their earnings equally among themselves

how much will the friend who earned $40 give to the others?

Amount given to others = $40 / 4

= $10

The friend who earned $40 will give $10 each to the others

Answer:

The vector that describes their hike from their starting position to their final destination is [tex]\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi][/tex].

Step-by-step explanation:

In this problem we assume that orthogonal axes coincide with the north and east. We proceed to translate each sentence from statement into vectorial equations:

(i) A group of hikers walks 3 miles east and then 1 mile north:

[tex]\vec r_{A} = 3\,\hat{i}+1\,\hat{j}\,\,\,[mi][/tex]

(ii) After taking a break, they then hike 4 miles east to their final destination:

[tex]\vec r_{B} = 4\,\hat{i}\,\,\,[mi][/tex]

The vector that describes their hike from their starting position to their final destination is the sum of the vectors deducted above. That is:

[tex]\vec r = \vec r_{A}+\vec r_{B}[/tex]  (1)

[tex]\vec r = (3\,\hat{i}+1\,\hat{j})+4\,\hat{i}\,\,\,[mi][/tex]

[tex]\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi][/tex]

The vector that describes their hike from their starting position to their final destination is [tex]\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi][/tex].

Answer:

Either- 200778.9263 or 81

Step-by-step explanation:

Type this into the calculator:

First: (1/9)^6= 1.881676423x10^-6

Then: 81^4= 43046721

Then multiply the two: (1.881676423x10^-6)x 43046721= 200778.9263

                                                Or

Try this- type ((1/9)^6)x(81^4) into the calculator which comes out to 81

((1/9)^6)x(81^4)=81

Depends on which level you are at in math.

Answer:

  81

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)^c = a^(bc)

  1/a^b = a^-b

  (a^b)(a^c) = a^(b+c)

__

  [tex]\left(\dfrac{1}{9}\right)^6\cdot81^4=9^{-6}\cdot(9^2)^4=9^{-6}9^8= 9^{-6+8}=9^2\\\\=\boxed{81}[/tex]

Answer:

x = 5

Step-by-step explanation:

Since both sides are given, set both sides equal to eachother.

3x + 1 = 5x - 9

Segment CM is on the left and segment MB is on the right. From now on, solve for x.

Step 1: Isolate x by itself by subtracting the lesser value

3x + 1 = 5x - 9

-3x        -3x                     the x's on the left cross out

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

 1 = 2x - 9

+9         +9                      having x on one side

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

10 = 2x

__________________________________________________________

Step 2: Divide each side by 2 to get rid of x's coefficient

10 = 2x

/2     /2

----------

5 = x

Solution: x = 5

__________________________________________________________

Solving for CB: Substitute x for both sides since x = 5

3(5) + 1 = side CM

15 + 1 = side CM

16 = side CM

__________________________________________________________

Solving for CB: Solve for the other side (segment MB)

5(5) - 9 = side MB

25 - 9 = side MB

14 = side MB

__________________________________________________________

Solving for CB: Lastly, add up the sides

16 + 14 = segment CB

30 = segment CB

__________________________________________________________

Applying the knowledge of midpoint of a segment, the value of x = 5.

Given:

[tex]CM = 3x+1\\\\MB = 5x-9[/tex]

To solve this, we would apply our knowledge of Midpoint of a Segment to create an equation that will help us solve for the value of x.

Thus:

[tex]CM = MB[/tex]

[tex]3x + 1 = 5x - 9[/tex]

[tex]3x - 5x = -1 - 9\\\\-2x = -10[/tex]

[tex]x = 5[/tex]

Therefore, applying the knowledge of midpoint of a segment, the value of x = 5.

Answer:

Step-by-step explanation:

5x−2y=18

5(0)−2y=18

-2y=18

y=-9

5x−2(0)=18

5x+0=18

5x=18

x=18/5

Answer: ZQ=61, ZP=119

Step-by-step explanation: knowing that these angles are supplementary, you can set up an equation using x. Angle ZP is 2x-3, and angle ZQ is x. Together they add up to 180. So 2x-3+x=180. 183=3x. X=61.
