Answer: C
Step-by-step explanation:
Since this is an isosceles triangle as indicated by the markers on QP and PR, we know that QS and SR are equivalent.
To find the value of n, we set QS and SR equal to each other.
6n+3=4n+11 [combine like terms]
2n=8 [divide both sides by 2]
n=4
Now that we know n=4, we know that A is incorrect. What we can do is use the value of n to solve for QS, SR, and QR.
QS
6(4)+3=13
Since the length of QS is 13, we know B is incorrect.
SR
4(4)+11=27
Since SR is 27, C is a correct answer.
QR
13+27=40
Since QR is 40, the only correct answer is C.
A kilometer is 1000 meters.
1000 time 750 equals 750000
So the answer is yes, 7500000 is greater than 750000
Answer:
1.
- Heat capacity is defined as the total amount of heat required to increase the temperature of a substance in 1°C.
- Specific heat is defined as the total amount of heat required to increase the temperature of a substance in 1°C per unit mass. Hence this property depends of the mass of the substance.
- Latent heat is the amount of energy absorbed or released by a substance in a phase change (physical change) without a change in temperature.
2.
- Degrees of freedom is the number of parameters that define the configuration of a system. For example, in a system with we want to know about the dynamic in the three dimension x,y,z and also about the rotation around a fixed axe we have four degrees of freedom.
- Equipartition theorem relates the temperature of a system with the average energy of the system (this average is taken for those degrees of freedom that appears quadratically).

Answer:
Draw and label a diagram!
htop of tower / 325 = tan 34°
hbottom of tower / 325 = tan 31°
height of tower = htop of tower + hbottom of tower
