If a toaster oven that is connected to a 120 v plug has 16 A of current running through it, what is the resistance?
Alenkinab [10]

Answer:

The resistance is 7.5 ohms

Step-by-step explanation:

V = IR

V = voltage  I is the current and R = resistance

120 = 16*R

Divide by 16 on both sides

120/16 = 16R/16

7.5 = R

The resistance is 7.5 ohms

Lisa is now six years older than Cheryl. In two years, Lisa will be twice as old as Cheryl. How old is Lisa now?
Elena-2011 [213]
--------------------------------------------------
Define x :
--------------------------------------------------
Let Cheryl be x years old.
Cheryl = x
Lisa = x + 6

--------------------------------------------------
In two years time:
--------------------------------------------------
Cheryl = x + 2
Lisa = x + 8

--------------------------------------------------
Lisa will be twice as old as Cheryl :
--------------------------------------------------
x + 8 = 2(x + 2)

--------------------------------------------------
Solve x :
--------------------------------------------------
x + 8 = 2(x + 2)
x + 8 = 2x + 4
x = 4

--------------------------------------------------
Find their age :
--------------------------------------------------
Cheryl = x = 4
Lisa = x + 6 = 4 + 6 = 10

--------------------------------------------------
Answer: Lisa is 10 years old now.
