Answer: The correction option is B, i.e., 140^{\circ}.

Explanation:

To find the angle F using protector first we have to study about the protractor.

In a protractor the angles are written in two scales. The angles of outer scale is increased in clockwise direction and the the angles of inner scale are increasing in anticlockwise direction.

The reason behind it is the property of supplementary angles. The sum of angles lie on straight line is always 180 degree.

When we have to find the angle we see the inner angles or inner semi circle or the angle in anticlockwise direction.

From the given figure it is noticed that the angles F lies on 40^{\circ} and 140^{\circ}.

The angle in anticlockwise direction is 140^{\circ}, therefore, the correct option is B.

prohojiy [21]

\huge\text{Hey there!}

\large\textsf{-4 + 3x = 20}\\\rightarrow\large\textsf{3x - 4 = 20}\\\\\large\text{ADD 4 to BOTH SIDES}\\\large\textsf{3x - 4 + 4 = 20 + 4}\\\large\text{CANCEL out: \textsf{-4 + 4} because that gives you \textsf 0}\\\large\text{KEEP: \textsf{20 + 4}} \text{ because it gives you the \textsf{x-value}}}\\\\\large\textsf{20 + 4 = \bf 24}\\\\\large\text{DIVIDE 3 to BOTH SIDES}\\\\\mathsf{\dfrac{3x}{3}= \dfrac{24}{3}}\\\large\text{CANCEL out: }\mathsf{\dfrac{3}{3}}\large\text{ because that gives you \textsf 1}

\large\text{KEEP: }\mathsf{\dfrac{24}{3}}\large\text{ because it helps gives you the result of the  \textsf{x-value}}\\\\\mathsf{x = \dfrac{24}{3}}\\\\\large\textsf{x= 24}\div \large\textsf{3}}\\\large\textsf{x = \bf 8}\\\\\boxed{\boxed{\huge\text{Therefore, your answer is: \textsf{x = 8}}}}\huge\checkmark

Help plz!!!! This is precal

Answer:

The remainder is 0 ⇒ 3rd answer

Step-by-step explanation:

* In the synthetic calculation we use the coefficient of the dividend

  with the value of x when the divisor = 0

∵ x - 1 = 0 ⇒ add 1 to both sides

∴ x = 1  

Step 1 : Write down the coefficients of the f(x) , put x = 1 at the left  

                         1        1     0     -1     1     -1    

                                ________________

Step 2 : Bring down the first coefficient to the bottom row.

                        1         1      0    -1     1    -1    

                               ________________

                                   1

Step 3 : Multiply it by 1, and carry the result into the next column.

                       1         1      0    -1     1    -1    

                               ____ 1_________

                                  1  

Step 4 : Add down the column

                       1        1       0    -1     1    -1    

                                ____1__________

                                 1      1

Step 5 : Multiply it by 1, and carry the result into the next column

                       1        1      0     -1     1     -1    

                              _____1___1_______

                                 1       1

Step 6 : Add down the column

                      1         1       0    -1      1     -1    

                                ____1___1______

                                 1       1      0

Step 7 : Multiply it by 1, and carry the result into the next column

                    1        1       0    -1      1     -1    

                               ___1___1___0______

                              1      1      0

Step 8 : Add down the column

                    1         1     0      -1      1      -1  

                          _____1____1__0_____

                              1      1       0      1

Step 9 : Multiply it by 1, and carry the result into the next column

                  1         1     0      -1       1      -1  

                          ____1____1___0___1___

                            1     1        0      1        

Step 10 : Add down the column

                  1         1     0      -1       1      -1  

                          ____1____1___0___1___

                            1     1        0      1         0

∴ The quotient is (x³ + x² + 1 ) and the remainder is 0

* The remainder is 0

Answer:

a = 370,000

b = 2,115,000

c = 4,230,000

city c is 11.4 times the population of city a

Step-by-step explanation:

10 to the 5 degree is 100,000. multiply that by 3.7 to get the population of City a.

City C is 2,115,000 * 2.

divide the population of City C by the population of City a.

4,230,000 ÷ 370,000= 11.43
