2. -55+(-31)= -55-31=-86

positive number and negative number= -negative number

3. 18+71=89

4. -14+21=7

Positive 7 because 21 is greater than -14

5. 12+(-56)= 12-56=-44

6. -4+18=14

7. -31+(-17)=-31-17=-48

In a series RL circuit, ET = 120 V, R = 40 Ω, and XL = 30 Ω. How much is EL?
dezoksy [38]

Firstly, we will draw

RL series circuit

ET = 120 V, R = 40 Ω, and XL = 30 Ω

Firstly, we will find current

I=\frac{E_T}{R+jX_L}

now, we can plug values

and we get

I=\frac{120}{40+j30}

now, we can find voltage across L

E_L=IjX_L

so, we get

E_L=\frac{120}{40+j30}(j30)

now, we can find absolute value

|E_L|=120\frac{30}{\sqrt{40^2+30^2}  }

|E_L|=120\frac{30}{ 50 }

|E_L|=120\frac{3}{ 5 }

|E_L|=72V...............Answer

Jordan was driving down a road and after 4 hours he had traveled 82 miles. At this speed, how many miles could Jordan travel in
babymother [125]
You can use a proportion.

4 hours is to 82 miles as 14 hours is to x miles

4/82 = 14/x

Cross multiply to get

4x = 14 * 82

4x = 1148

x = 287

287 miles
