Find the equivalent resistance of a series circuit with a voltage of 12 V and three resisters each with 5 ohms of resistance.

Re = 15 [ohm]

Explanation:

If the resistors are in series, the equivalent resistance is equal to the algebraic sum of the resistors.

Re = 5 + 5 + 5

Re = 15 [ohm]

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
