Answer:
what's the answer choices
The total installations they would have completed is 64 installations
<h3>Quantity & Rate </h3>
From the question, we are to determine how many total installations they would have completed
If the technician can complete an installation in 1.5 hours
Then,
In 60 hours, the technician will complete installations
= 40
Therefore, the technician would have completed 40 installations
- For the less experienced colleague
If it takes the less experienced colleague 2.5 hours to complete an installation
Then,
In 60 hours, the less experienced colleague will complete installations
= 24
Therefore, the less experienced colleague would have completed 24 installations
Hence, the total installations they would have completed is 40 + 24 = 64 installations

Answer:
Photosynthesis, process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing, photosynthesis provides the basic energy source for virtually all organisms.
Explanation:
The answer is: single replacement.
Single replacement is reaction where neutral element metal or nonmetal become an ion as it replaces another ion in a compound.
In this balanced chemical reaction magnesium (Mg) replaces copper (Cu).
Magnesium changes oxidation number from 0 to +2 (oxidation) and copper changes oxidation number from +2 to 0 (reduction).
Reactivity series is an empirical progression of a series of metals, arranged by their reactivity from highest to lowest (alkaline metals have highest reactivity and Noble metals lowest reactivity):
K > Ba > Sr > Na > Ca > Mg > Be > Al > Mn > Zn > Cr> Fe > Cd > Co > Ni > Sn > Pb > H(in acids) > Cu > Hg > Ag.
Metal higher in the reactivity series will displace another and it will be oxidized.
