Answer:

easy to carry

valuable

Explanation:

Paper money has helped humanity to easily carry things that have a high value and that they can exchange for other goods and services without the necessity of acually carrying other items of value other than the paper money, prior to this people would often exchange products for other products for a certain value, and the cost of things would differ depending on what you traded and to whom, paper money and coins have helped standarized costs and prices.

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.

Which expression is equivalent to x2 - 12x + 11?
Serjik [45]

Answer: o (x - 11)(x - 1)

Explanation:

You can find two values that has a sum of -12 and a product of 11:

x^{2} -12x+11\\(x-11)(x-1)

Or you can use the quadratic formula:

\frac{-b+-\sqrt{b^{2} -4ac} }{2a}

Where:

  • a = 1
  • b = -12
  • c = 11

The maximum activity level (which is 1.00) of an enzyme occurs at a pH level of 4 pH units.
Zanzabum

Answer:

O2 affinity depends on the pCO2 and pH.

Higher pH -> Higher O2 affinity -> Higher O2 saturation at higher pH level

Higher pCO2 -> Lower O2 affinity -> Higher O2 saturation at lower pCO2 level

This is a benefit because it allows the affinity of Hb in venous blood conditions (lower pO2, higher pCO2, and lower pH) to be much lower than in arterial conditions. Therefore, when blood goes from arterial to venous, the oxygen concentration decreases much more dramatically due to more oxygen (around 2x) being released to the tissues, which is possible due to the changes in affinity caused by the Bohr effect.
