For this case we must compare the unit costs of the options given and determine which is the best option.
Option 1:
Six yards of rope costs $5.50
Option 2:
Four yards costs $ 4.75
Thus, the best option is the first. It is the lowest unit cost.
Answer:
The best option is the first. It is the lowest unit cost.
Answer:
81.7 in (nearest tenth)
Step-by-step explanation:
Given:
Substituting given value into the formula:
Below are the choices that can be found from other sources:
A. 42
<span>B. 45 </span>
<span>C. 47 </span>
<span>D. 48 </span>
<span>E. 49
</span>
The answer is C or 47. The object’s resultant angle of motion with the +x-axis after the collision is 47. The reason for that is f<span>rom object A’s x-momentum is 5.7 × 104 kilogram meters/second and its y-momentum is 6.2 × 104 kilogram meters/second, we know that tan of the angle from the x-axis is 6.2 / 5.7 = 1.09 and acrtan 1.09 = 47.4</span>
