Answer:
6w^3
Step-by-step explanation:
It can't be any answer with cubed in it because that would be volume. So, A and C magically vanish. If we know that the length of a cube is w that means that all sides are w. There are six faces on a cube. If we want to find surface area we will have to add up the area of all faces. the area of one face will be w^2. We multiply that number by six and we get 6w^3.

Step-by-step explanation:
The percentage of increase in Roberto score is 14.87%, if Roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz.
Step-by-step explanation:
The given is,
Roberto score on math quiz at last week is 74
This week he made an 85 on the quiz
Step:1
Formula to calculate the percentage of increase the score,
× 100...........(1)
From the given,
Final score = 85
Starting score = 74
Equation (1) becomes,
× 100
= 
× 100
= 0.1486486 × 100
= 14.86486 %
≅ 14.87 %
Percentage of increase = 14.87 %
Result:
The percentage of increase in Roberto score is 14.87%, if Roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz.
Answer: The electroscope had a negative charge before the experiment started. When the negatively charged rod comes near the electroscope more electrons are repelled down to the metal pieces and the metal pieces move farther away from each other.
Step-by-step explanation: First of all, how we know the answer is not A or B is because unlike charges attract each other which means the metal pieces would not spread out. Now that we narrowed it down to C and D we can find the answer, In answer choice D it states that the negatively charged rod attracted the electrons from the electroscope, if that happened then something would happen to the rod, not the electroscope. In answer choice C it says that the rod repels the electrons downward on to the metal pieces, which would cause the metal pieces to spread out since they are both negative. Sorry, I'm not the best with explaining, I hope you understand.
