Rebecca is playing a video game that involves planting and cutting down trees. She moves up an energy level for each tree she pl

ants, and she moves down a level for each tree she cuts. If Rebecca reaches energy level 10, she will earn bonus points. Rebecca is currently at energy level 4. The results of her next 3 turns are: Turn 1: 6 trees cut Turn 2: 8 trees planted Turn 3: 1 tree cut
USING ONLY ADDITION, write an expression that represents Rebecca's score after these three turns. (Remember that she starts at an energy level of 4.)

Answer:

she ends at level 5 after her 3 turns

Explanation:

Rebecca starts at level 4 if she cuts down 6 trees for her next turn she loses 6 levels we can rewrite this as -6 so 4 + (-6) = -2 her next turn is planting 8 trees so she goes up 8 levels -2 + 8 = 6 her last turn she cuts down one tree

6 + (-1) = 5

altogether 4 + (-6) + 8 + (-1) = 5

A container of argon with a volume of 22 ml has a pressure of 101.0 kPa.
Alexeev081 [22]

Answer:

The new pressure is 44.4 kPa.

Explanation:

We have,

Initial volume, V_1=22\ ml

Initial pressure, P_1= 101.0\ kPa

It is required to find the new pressure when the volume is increased to 50 ml. The relationship between pressure and volume is known as Boyle's law.

PV=k\\\\P_1V_1=P_2V_2

P_2 is final pressure

P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{22\times 101\times 10^3}{50}\\\\P_2=44440\ Pa\\\\P_2=44.4\ kPa

So, new pressure is 44.4 kPa.

Answer:

Aluminum

Explanation:

<h3> <em>Aluminum would be the best choice to reuse  copper from the copper chloride solution because it  In the aluminum–copper reaction, the chloride ions help remove the aluminum oxide coating so that a reaction can take place through the oxidation of aluminum and the reduction of copper ions.The aluminum–copper chloride reaction is a simplified version of a waste reclamation and reduction strategy for handling toxic-waste materials. </em></h3>
