Answer:
-20⅖
Step-by-step explanation:
5⅔(-3.6)
(17/3)(-3.6)
17(-3.6/3)
17(-1.2)
-20.4
-20 ⅖
Answer:
y = -17/2
Step-by-step explanation:
Substitute with the givens.
30= 8(8) + 4y.
Multiply parentheses.
30 = 64 + 4y
Subtract.
30-64= -34
-34 = 4y.
Divide each side by 4.
y = - 8.5, or -17/2
hope that is right!
Simplify:
Subtract 1.12 on both sides:
Multiply both sides by 2:
Answer:
735N
Step-by-step explanation:
According to Newton's second law;
Force = mass * acceleration due to gravity
'
Given
Mass = 75kg
Acceleration = 9.8m/s^2
Substitute into the formula;
F = 75 * 9.8
F = 735N
Hence the force required is 735N
Answer: 12.3 ft.
Step-by-step explanation:
In the given picture we can see there is a right triangle with hypotenuse 15 ft.
Using trigonometry in the given right triangle, we have
Hence, the length of rope A = 12.3 ft.
