All the workers on a 6 person team work at the same rate.
yawa3891 [41]

The number of hours it would take for half of the workers to complete the same job is 96 hours.

<h3>How much does it take to 6 workers to complete the job?</h3>

It is already known 6 workers working at the same rate can complete this job in a total of 48 hours, which means each of the workers represents approximately:

  • 8 hours of work (48 / 6 = 8).

<h3>What happens if the number of workers is reduced?</h3>

In this case, it expected the total of hours to complete the same job increase. Moreover, the time will proportionally increase depending on the reduction of workers. Here are some examples:

  • -1/3 of workers = +1/3 of time
  • -1/5 of workers = + 1/5 of time

This means by reducing the workers to half of the team (-1/2) the time will duplicate.

  • 2 x 48 = 96 hours.

Note: This question is incomplete; here is the possible complete question.

All the workers on a 6 person team work at the same rate. All six members of the team, working together, are able to pour foundations in 48 hours. How many hours would this job take if only half of the team worked on this task.

A sample of a compound that contains only the elements c, h, and n is completely burned in o2 to produce 44. 0 g of co2, 45. 0 g
Elan Coil [88]

Answer:

B. CH₅N

Explanation:

The combustion reaction of a compound CₐHₓNₙ with O₂ is:

CₐHₓNₙ + O₂ → a CO₂ + X/2 H₂O + n NO₂

Where 1 mole of CₐHₓNₙ with an excess of O₂ produce a moles of CO₂, X/2 moles of H₂O and n moles of NO₂

Thus, you need to convert the mass of CO₂ and H₂O to moles to find the C:H ratio and determine a possible empirical formula thus:

Moles CO₂ (Molar mass 44g/mol):

44g ₓ (1mol / 44g) = 1 mole CO₂ = 1 mole C

Mole of H₂O (Molar mass 18g/mol):

45g ₓ (1 mol / 18g) = 2.5 moles H₂O = 5 moles H

Thus, in the compound you have 5 moles of H per mole of C, and a possible empirical formula is:

B. CH₅N

The only structure that meet this C:H ratio

Which option below is not a potential risk of purchasing a used car? used cars can require repairs sooner shorter lifespans of t
tamaranim1 [39]

Answer:

C.) Used cars can have lower initial cost

Explanation:

It's not a risk, as this is actually a benefit.

Most used cars are sold cheaper due to the fact that they will have shorter lifespans, may need repairs sooner, or just generally will not run as well. Because of this, the only thing that is NOT a risk is C.)
