Answer:
D
Step-by-step explanation:
Let the total production order be X. The combined rate is thus x/36 orders per hour.
Now, we know that the three machines are working at the same constant rate. This means that individual rate for each of the machines will be x/36 divided by 3 and that gives x/108 per machine.
Now, we are having another machine coming at the same constant rate. This means we are adding an x/108 rate to the preexisting x/36.
The new total rate thus becomes x/108 + x/36 = 4x/108
Now we know that the total new rate is 4x/108. Since the total work doesn’t change and it is still x, the time taken to complete a work of x orders at a rate of 4x/108 order per hour would be x divided by 4x/108 and this is x * 108/4x = 108/4 = 27 hours

Answer:
<h2>120 cm³</h2><h2 />
Step-by-step explanation:
this is a ratio and proportion of two similar solids
vol A = 60 cm³ and A = 3cm
vol B = ? and B = 6 cm
<u> 60 </u> = <u> 3 </u>
B 6
do cross multiply:
3B = 60(6)
B = 120 cm³
therefore, the vo. of B is 120 cm³
