Answer:
14 ohms
Step-by-step explanation:
The resistance varies directly with length, so increasing the length by a factor will increase the resistance by the same factor.
__
The length of the wire increased by a factor of 1.4 from 100 ft to 140 ft. That means the resistance will increase by a factor of 1.4 from 10 ohms to 14 ohms. (The diameter did not change.)
The longer wire will have a resistance of 14 ohms.
Since prime numbers only have two factors (itself and 1) then it would have to be the same number. So it would be the number besides one. Ex. Prime number: 7, the GCF would be 7 if it was compared with itself.
False because you can subtract your way out of the set of whole numbers
We will use the INVERSE OPERATION of multiplication which is division. Lets do it:-
3x = 27
27 ÷ 3 = x
27 ÷ 3 = 9
x = 9
CHECK OUR WORK:-
3x = 27
x = 9
3 · 9 = 27
We were RIGHT!!!!!
So, x = 27.
Hope I helped ya!!! xD
Answer:
21 is 20% of 105
Step-by-step explanation:
20% * x = 21
20/100 * x = 21
x = 21 * 100/20
x = 105
If you are using a calculator, simply enter 21×100÷20, which will give you the answer.
