Answer:

<h2>A.r=\frac{27-p}{3p}</h2>

Step-by-step explanation:

The given formula is

A=p(1+rt)

Where A=27 and t=3

To solve for r, first we need to move p

\frac{A}{p}=1+rt

Then, we move the term 1

\frac{A}{p}-1=rt

Finally, we move the factor t

\frac{\frac{A}{p}-1 }{t} =r

Replacing given values, we have

\frac{\frac{27}{p}-1 }{3} =r\\r=\frac{\frac{27-p}{p} }{3} \\r=\frac{27-p}{3p}

Thereofre, the right answer is A.

It is 42 1/2 miles from Eaton to Baxter and 37 4/5 miles from Baxter to Wellington. How far is it from Eaton to Wellington if yo
mina [271]
All you need to do is add the miles from Eaton to Baxter and from Baxter to Wellington to get your answer...

42 + 37 = 79 

Now we need to add the fractions 

\frac{1}{2} +  \frac{4}{5} = ...&#10;

To add we need a common denominator. 
2 and 5 can both go into 10, so that will be a our common denominator. 
Now you have... 
\frac{5}{10} + \frac{8}{10} = \frac{14}{10}
which is equal to 1 \frac{2}{5}
add that to the 79 we got earlier ...

The toal and final answer is 80 \frac{2}{5} miles !
Hope I helped and remember to vote this as the brainliest answer ! :)

What is the median of the following string of values?<br>16, 95, 3, 37.97. 13, 27.42, 64, 14​
liubo4ka [24]

Answer:

21.71

Step-by-step explanation:

1) you need to order then by the size

      3, 13, 14, 16, 27.42, 37.97 ,64, 95

2) if there is an odd amount of numbers then the median would be the center term. but if it an even number then you add the two middle terms together and divide them by 2.

     16+27.42= 43.42

     43.42 divided by 2=21.71

Hope this helped
