Two 120 resistors are connected in parallel across voltage supply of 10 vdc what’s the current in this circuit
Daniel [21]

Answer: 0.167

Step-by-step explanation:

This is an applied mathematics question

Resistors in parallel  ⁾/R = ¹/₁₂₀ + ¹/₁₂₀ since the resistor is two 120

Therefore , resolve into fraction now yield

                       ¹/R                              =         1 + 1  

                                                                    -------

                                                                     120

                                                          =         2/120

                                                          =          ¹/₆₀

Therefore,                                  ¹/R   =      ¹/₆₀

 Cross multiply to get R the resistance

                                                      R  =  60

From formula,                                V = IR where I is the current

There fore making I the subject of the formula

                                                        I = V/R

                                                          = 10/60

                                                          = 0.166

                                                          = 0.167 A, A = ampere which is the unit of current.

Geometry math question please help
denis-greek [22]

In parallelogram the opposite sides are equal. Therefore we have the equation:

8a-4=6a+10\ \ \ |+4\\\\8a=6a+14\ \ \ |-6a\\\\2a=14\ \ \ |:2\\\\\boxed{a=7}

In the parallelogram, the sum of measures of the angles at one side is 180°. Therefore we have the equation:

(18b-11)+(9b+2)=180\\\\(18b+9b)+(-11+2)=180\\\\27b-9=180\ \ \ |+9\\\\27b=189\ \ \ \ |:27\\\\\boxed{b=7}

Answer:

c = a + b → c = 7 + 7 = 14

A. 14

What is the length of the third side of a right triangle if it is known that the two of the sides have lengths 5 and 13. How man
Shalnov [3]

Step-by-step explanation:

We are given with the two sides of a right angled triangle having lengths of 5 and 13. It is required to find the length of the third side of a right triangle. We know that hypotenuse of right angled triangle is the longest side.

For right angle triangle, we use Pythagoras theorem as :

H²=P²+B²

P is perpendicular distance

B is base

Putting H = 13 and P = 5, then

B² = H²-P²

B² = (13)²-(5)²

B²=144

B=12

So, the length if the third side of a right triangle is 12. It is the only solution.
