Answer:
1
Step-by-step explanation:
I belive its one because 3^2 is 9 and 9+1 = 10
to make sure it not just once 3^3 is 27 and 27+1=28
Answer: 19.13 yd²
Step-by-step explanation:
1. By definition, you have that 1 square meter is equal to 1.19599 square yards. You can express it as following:
1 m²= 1.19599 yd²
2. Then, keeping the information above on mind, you can make the conversion from 16 m² to yd² as it is shown below:
Therefore, you have that 16 m² is equivalent to 19.13 yd².

The gas exerts a pressure of 218.75 kPa when its volume is reduced to 2.0 L, following the behavior of an ideal gas.
Ideal gas behavior:
Suppose the initial volume of carbon dioxide gas is V = 3.5l
Initial pressure is P = 125 kPa
Since the volume is reduced to 2.0l, the final volume is shown as V'= Will be done. 2L
The final pressure of the gas is P'.
We consider the behavior of gas to be ideal. From the ideal gas equation, it becomes as follows.
PV = P'V'
125 × 3.5 = P'× 2
P'= 218.75 kPa
Therefore, the final pressure is 218.5 kPa.
