AS we don't know the width so let consider width=x inches
According to given condition
length = (3x -5) inches
TV screen is rectangular shaped so
Perimeter= 2( length +width) =2{(3x-5)+ (x)} equation 1
also given Perimeter = 150 inches equation 2
comparing equation 1 &2
2{(3x-5)+ (x)} =150
2{3x-5+x} =150
2{4x-5} =150
8x-10 =150
Adding 10 both sides
8x -10 +10 =150+10
8x=160
dividing 8 both sides
8x/8= 160/ 8
x= 20 inches width of screen.
length =( 3x-5) ={3(20) -5}
=60-5
length =55
Potential gravitational energy:

10kg • 10m/s^2 • 0.02 =
2 Joules
I don’t think anyone knows this one not even James
Sample space={A,R,I,T,H,M,E,T,I,C}
1ST (Choosing T) ==> P(1st draw) = 2/10 = 1/5 = 0.2
2ND (Choosing again a T) ==> P(2nd draw) = 1/9 = 0.11
Since it's a conditional probability then P (1st T AND 2nd T) = 0.2 x 0.11 =0.022
