The resistance (R) in a wire increases when the length of the wire (L) increases. Write the correct equation for this scenario, and solve for when the length is 1. Length Resistance 10 2 15 3 a. R = 20 over L; R = 20
b. R = .2L; R = 5
c. R = .2L; R = .2
d. R = 20 over L; R = 5

Answers

Answer: c. R = 0.2L ; R =0 .2

Step-by-step explanation:

Given: When length of wire is $L_1=$ 10 units, then resistance of wire $R_1=$ =2 ohm

When length of wire is $L_2=$ 15 units, then resistance of wire $R_2=$ =3 ohm

Since, the resistance (R) in a wire increases when the length of the wire (L) increases. Therefore, they are directly proportional.

$(R)/(L)=(R_1)/(L_1)$

$(R)/(L)=(2)/(10)\n\Rightarrow\ R=0.2L$

Now, for Length L=1 unit, we have

$R=0.2(1)=0.2$

How do you use long division by dividing 32000 divided by 500

Answers

32000 and 500 , so the number 32000 has three 0 and 500 2 , so you can take off two 0 from 32000, which equals to 320 .You have to find a number that times 5 equals 320 or almost , the most approaching number is 6 , because 5 times 6 equals 30 , then you have to subtract, the result of the subtraction is 2 , 2 is less than 5 so we have to put a zero , so we got 20 , which number times 5 can give you 20 ? , 4 , so your answer is 64 .

I think I got the answer but I'm not sure. Help?

Answers

I wish I could see your answer in the picture. Then we could put it into the original equation and see if it checks.

It won't, because you made a slight mistake in your first line, where you were
eliminating the parentheses on the right side:

-4(x- 3) = -4x +12 . . . . . not -4x -12 .

That should get you all fixed up.

When you combine like terms from your first line,
your second line will be
4x + 6 = 30 - 4x

and it's all smooth sailing from there.
