Alchen [17]

$g(-3)=\frac{-3+1}{-3-2}=\frac{2}{5} \\ \\ h(-3)=4-(-3)=7 \\ \\ (g\times h)(-3)=7\left(\frac{2}{5} \right)=\boxed{\frac{14}{5}}$

Working alone at its own constant rate, a machine seals k cartons in 8 hours, and working alone at its own constant rate, a seco

Harlamova29_29 [7]

Answer:

$66\dfrac{2}{3}\%$

Step-by-step explanation:

Given,

The number of cartons = k,

Time taken by machine a = 8 hours,

So, the number of cartons made by machine a in one hour

= $\frac{\text{Cartons in 8 hours}}{8}$

= $\frac{k}{8}$

Time taken by machine b = 4 hours ,

So, the number of cartons made by machine b in one hour

= $\frac{k}{4}$

Total cartons made in 1 hour = $\frac{k}{8}+\frac{k}{4}$

$=\frac{k+2k}{8}$

$=\frac{3k}{8}$

∵ for the whole number value of k,

$\frac{k}{4}>\frac{k}{8}$

i.e. machine b is faster,

Also, the percent of the cartons were sealed by the machine b

$=\frac{\text{Cartons made in 1 hour by machine b}}{\text{Total cartons}}\times 100$

$=\frac{\frac{k}{4}}{\frac{3k}{8}}\times 100$

$=\frac{2}{3}\times 100$

$=\frac{200}{3}$

$=66\dfrac{2}{3}\%$

Hence, OPTION D is correct.
