Four resistors are connected in series such that their total resistance is 50ohm . If the resistance of resistors is 5 ohm , 10o
Katyanochek1 [597]
<h2>Answer:</h2>

\boxed{R_{4}=20\Omega}

<h2>Step-by-step explanation:</h2>

If resistors are in series, so the current  I is the same in all of them. In this problem we have four resistors. So, we can get a relationship between the Equivalent resistance  of series combination and the four resistors as follows:

R_{eq}=R_{1}+R_{2}+R_{3}+R_{4}

R_{eq} is the total resistance 50\Omega. Moreover:

R_{1}=5\Omega \\ R_{2}=10\Omega \\ R_{3}=15\Omega

Therefore:

50=5+10+15+R_{4} \\ \\ R_{4}=50-(5+10+15) \\ \\ R_{4}=50-30 \\ \\ \boxed{R_{4}=20\Omega}

What does 4/54=x/36 equal
dalvyx [7]

First reduce the fraction so your equation looks like this:

2/27=x/36

Now cross multiply to simplify

72=27x

Now change sides

27x=72

Now divide both sides by 27

X= 8/3

Now you are left with your answer:

x= 8/3

Hope this helps! :3

Please help math finals!!!What is the equation of the line that has a slope of 14 and goes through the point (8,−3)
katovenus [111]

I'm taking the same final test.

The answer is y= 1/4x - 5

How? Well in this case we are using the formula y= mx + b

Substituting it with the given point (8, -3) and the slope 1/4

it'll look like -3 = 1/4 (8) + b

Next we solve.

-3 = 1/4 (8) + b

-3 = 8/4 + b

-3 = 2 + b

-2 -3 = b

-5 = b

so we now we know that b = -5.

All we have to do is substitute that into the equation to get our final answer (this time, without the point 8,-3).

Our answer in the end is y = 1/4x -5

Write a pythogorean triplet whose smallest number is 20?​
vladimir2022 [97]

Answer:

20,21,29 or 20, 99 and 101.

Step-by-step explanation:

a^{2} +b^{2} =c^{2}

20^{2} +21^{2} =29^{2}

400+441=841

OR:

a^{2} +b^{2} =c^{2}

20^{2} + 99^{2} = 101^{2}

400+9801=10201
