Answer:
about $7.43 per hour
Step-by-step explanation:
52/7 = 7.43
answer:
x = 4
or 5.6568
step-by-step explanation:
- know the formula and plug in
formula: a^2 + b^2 = c^2
- now plug in what we have
- whatever the RIGHT ANGLE points to is the HYPOTENUSE or c
- the other two sides are the "legs" or a and b
a^2 + b^2 = c^2
7^2 + b^2 = 9^2
49 + b^2 = 81
b^2 = 32
b = 4
- in this case, b would be used as x
x = 4 or 5.6568 (exact value)

Step-by-step explanation:
Volume of rectangular prism :
= Base Area × h = l × w × h
Volume of triangular prism :
= Base Area × h
Cuz the base area of triangular prism, the volume is :
(½ × l × w) × h
= ½ lwh
So, the volume of a triangular prism is half of a rectangular prism
Answer:
Step-by-step explanation:
Given:
Force, f = 9000 lb
Young modulus, E = 10,000,000 psi
Stress, S = 30000 psi
Elongation, x = 0.50 in
Length, L = 16 ft
Converting ft to in,
12 in = 1 ft
= 192 in
Young modulus, E = stress/strain
Stress = force/area, A
Strain = elongation, x/Length, L
Maximum stress = 30,000 psi
Stress = force/area
Area = 9000/30000
= 0.3 in^2
Using minimum area of 0.3 in^2,
A = (pi × d^2)/4
0.3 = (pi × d^2)/4
= sqrt(1.2/pi)
diameter, d = 0.62 inches
