Answer:
25%
Explanation:
If there is 20% scrap, then
80% of (production + scrap) = 72 pcs/hr
Now,
![\frac{80}{100} \times (72+scrap)= 72 pcs/hr\\0.80\times (72+Scrap) = 72 \\ 72+Scrap = \frac{72}{0.80}\\72 + Scrap = 90\\Scrap = 18 pcs /hr](https://tex.z-dn.net/?f=%5Cfrac%7B80%7D%7B100%7D%20%5Ctimes%20%2872%2Bscrap%29%3D%2072%20pcs%2Fhr%5C%5C0.80%5Ctimes%20%2872%2BScrap%29%20%3D%2072%20%5C%5C%2072%2BScrap%20%3D%20%5Cfrac%7B72%7D%7B0.80%7D%5C%5C72%20%2B%20Scrap%20%3D%2090%5C%5CScrap%20%3D%2018%20pcs%20%2Fhr)
The percent increase in labor productivity is,
.
Or it can be written as 25% of which would give 80 pieces per hour.
Answer:
solute + solvent = solution
Explanation:
solute is <em>Any substance that is dissolved in a liquid solvent to create a solution</em>
solvent is <em>A liquid that dissolves a solid, liquid, or gaseous solute, resulting in a solution.</em>
and.
solution is <em>A homogeneous mixture, which may be liquid, gas or solid, formed by dissolving one or more substances.</em>
Electric current or electricity

Answer:
Option D - 0.2 s
Explanation:
We are given;
Initial velocity; u = 7 m/s
Height of table; h = 1.8m
Now,since we want to find the time the car spent in the air, we will simply use one of Newton's equation of motion.
Thus;
h = ut + ½gt²
Plugging in the relevant values, we have;
1.8 = 7t + ½(9.8)t²
4.9t² + 7t - 1.8 = 0
Using quadratic formula to find the roots of the equation gives us;
t = -1.65 or 0.22
We can't have negative t value, thus we will pick the positive one.
So, t = 0.22 s
This is approximately 0.2 s
