Answer:
R = 3/50
Step-by-step explanation:
If you are trying to solve for a variable,
1. Simplify both sides of the equation:
3/4 - 5/6R = 7/10 will now be (-5/6r) + 3/4 = 7/10
2. Add -3/4 from both sides of the equation:
(-3/4) + 3/4 = 0 and (-3/4) - 7/10 = -1/20.
You will be left with: -5/6r = -1/20.
3. Divide both sides by (-5/6).
(-5/6r) / -5/6 = 1R or just R. (-1/20) / -5/6 = 3/50
You are left with the answer:
R = 3/50
<em>I hope this helps!</em>
Y = -3/8x - 7....add 3/8x from both sides
3/8x + y = -7 ...multiply both sides by 8
3x + 8y = - 56 <==
The correct answer is 14.2 lb which is choice D.
Let:
F = minimum force required to prevent ball from rolling down the ramp
The formula will be:
F = w * sin theta
F = w * sin (39 degrees)
F = 22.6 * sin (39)
= 14.2 lb (this is rounded to the nearest tenth)
Answer:
