Tcecarenko [31]

Answer:

14.4% decrease

Step-by-step explanation:

Here is the formula for finding the percentage of decrease:

(starting value - final value) / starting value * 100.

So for your question,

\frac{5289-4530}{5289} =.0144\\.0144 * 100 = 14.4\\/

There was a 14.4% decrease within 50 years.

4. 10. 4 Test (CST):
kompoz [17]

Based on the value of the annuity, the amount it earns, and the compounding period, the money paid to Nathan each month will be B. $5,840.62.

<h3>How much will Nathan be paid monthly?</h3>

The amount Nathan will be paid is an annuity because it is constant.

First find the monthly interest and the compounding period in months:
= 4.8/12 months

= 0.4%

Number of compounding periods:

= 20 x 12

= 240 months

The monthly payment is:

Present value of annuity = Annuity x ( 1 - (1 + rate) ^ -number of periods) / rate

900,000 = A x ( 1 - (1 + 0.4%)⁻²⁴⁰) / 0.375%

900,000 = A  x 154.0932

A = 900,000 / 154.0932

= $5,840.62.

A baseball field is in the shape of a square. The
lina2011 [118]
Since the distance in between each plate is 90ft. We know from home to 1st is 90ft. To get to 2nd from first is also 90ft. So 90 + 90 is 180ft.

Now this question is weird because it could be asking how far would a baseball player would have to run to get to 1st then 2nd

Or

Could be asking the distance from Home to 2nd without going to 1st. So just a straight line from home to 2nd.

If that’s the case we need to use the Pythagorean theorem

Our setup would be 90^2 + 90^2 = c^2
Adding A and B will get us 16200. Now we need to divide to get to the other side. But C is squared. So we need to Square root 16200. Which is 127.28ft.
