Answer:
$1.56 per pound
Step-by-step explanation:
18.72/12 = 1.56
Apply the Pythagorean theorem
a^2 + b^2 = c^2
a = 5, b = 13.
5^2 = 25, 13^2 = 169
25 + 169 = 194
square root 194 = 13.928, rounded to nearest foot = 14 ft.
The minimum ladder length required to reach the top of the wall = 14 ft.
Answer:
x=2
TU:4(2)-1=7
UB: 3
TB: 10
Step-by-step explanation:
4x-1+2x-1=5x
6x-2=5x
6x=5x+2
subtract 5x from both sides
x=2
TU: (4x-1)
4(2)-1
8-1
7
TU:4(2)-1=7
UB: (2x-1)
2(2)-1
4-1
