Answer:
C
Step-by-step explanation:
The area (A) of a triangle is calculated as
A =  bh ( b is the base and h the perpendicular height )
 bh ( b is the base and h the perpendicular height )
Here b = 19 and h = 16 , thus
A = 0.5 × 19 × 16 = 152 yd² → C
 
        
             
        
        
        
It would be Y=80

Answer: d. None of the above are correct.
Step-by-step explanation: Noise is a superfluous random alteration in an eletrical signal. There are different types of noises created by different devices and process. Thermal noise is one of them. It is unavoidable because is created by the agitation of the charge carriers, due to temperature, inside an eletrical conductor at equilibrium and is present in all eletrical circuits. 
The formula to find the thermal noise power (N) is: N =  .T.B, where:
.T.B, where:
  is Boltzmann constant (1.38.
 is Boltzmann constant (1.38. J/K);
J/K);
T is temperature in Kelvin;
B is the bandwith;
Calculating the thermal noise power:
N = 1.38. ·292·40
·292·40
N = 16118.4. dBm
 dBm
The thermal noise power [N] = 16118.4. dBm
 dBm
Noise power density or simply Noise density (N₀) is the noise power per unit of bandwith and its SI is watts per hertz. 
For thermal noise, N₀ = kT, where
<em>k </em>is the Boltzmann constant in J/K;
T is the receiver system noise temperature in K;
N₀ = 1.38. . 292
 . 292
N₀ = 402.96. W/Hz
 W/Hz
The thermal noise power density [N₀] = 402.96. W/Hz

Volume of a cone formula: V = πr²*h/3
V = volume
r = radius
h = height
Solve with the given values.
V = π(7)²*19/3
V = π(49)*19/3
V = 153.86*19/3
V = 974.94...
Round to the nearest one.
974.94... → 975.0
Therefore, the answer is 975.0yd³
Best of Luck!
