Help A.S.A.P please thank you and please :D
Lina20 [59]

Answer:

Emma was right to say that both packages are close to 2 pounds.

If we round-off the weights of both to the nearest whole number we would get 2 pounds on both. We look at the the difference of both from 2 pounds we get the following:

2.36 - 2.0 = 0.36

2.09 - 2.0 = 0.09

The smaller the difference the closer it is to the base value. So we can say that the closest one is 2.0 pounds is the package that weighs 2.09 pounds.

If the radius of a circle is 75 hundredths of a meter, what is the diameter?
givi [52]
We know that the diameter of a circle is 2 times the radius.

If the radius is 0.75 meters, then the diameter must be 2 x 0.75 meters = 1.5meters

Value discounting refers to the fact that the percieved value of the reinforcer is less the longer you have to wait for it. See

Answer:

there is an economic principle that states that 1 dollar today is worth more than 1 dollar in the future, since an invested dollar could earn interests and gain value.

For example, we can assume a 6% interest rate (0.5% monthly interest rate), and using the present value formula we can determine the present value of $100:

  • given to us in 30 days = $100 / (1 + 0.5%)¹ = $99.50
  • given to us in 150 days = $100 / (1 + 0.5%)⁵ = $97.54
  • given to us in 300 days = $100 / (1 + 0.5%)¹⁰ = $95.13

In order to calculate the value of $100 given to us tomorrow, we would need to determine a daily interest rate = 6% / 360 = 0.00017

  • $100 given to us tomorrow = $100 / (1 + 0.00017)¹ = $99.98

since the amount of money is not that large and the interest rate is rather low, the difference in value is not that large. But imagine if you used a 24% interest rate instead of 6% (monthly interest rate = 2%)

  • $100 given to us in 30 days = $100 / (1 + 2%)¹ = $98.04
  • $100 given to us in 150 days = $100 / (1 + 2%)⁵ = $90.57
  • $100 given to us in 300 days = $100 / (1 + 2%)¹⁰ = $82.03

as the interest rate increases, the present value decreases.
