You can multiply the number and the answer is d
Answer:
Step-by-step explanation:
When negatively charged rubber rod is brought close to sphere X it induces positive charge on sphere and simultaneously negative charges is induced in the sphere opposite to the side of rod .
At the same time Sphere Y is touched to the sphere X , this causes the negative charge to shift to the sphere Y with the help of negative charged rod which repels the electrons to sphere Y.
When rubber rod is moved far away from X and Y then final charge possessed by X and Y spheres are
X:Positively charge
Y:Negatively charge
Jack's current monthly bill is
(1200 kWh +400 kWh)*($0.075/kWh) = $120
On the interval use plan, Jack's monthly bill would be
(1200 kWh)*($0.03/kWh) + (400 kWh)*($0.15/kWh) = $36 + 60 = $96
If Jack were to switch, his savings would be $120 -96 = $24.
The appropriate choice is ...
b. Jack should switch to the interval use plan, which would save him $24 per month.
Hi there!
For number 1 it shows that the last two blanks would be 8/8 and 4/4 since adding 1/8 would be 8/8 and adding 1/4 would be 4/4.
For number 2, it would be 3/6 or a half. It wants to have another equivalent to 3/6 and with dividing 3 for each side, it would be 1/2.
Answer: False
Reason: It should be x-a instead of x+a
