If the scale on a map is 1/4 in. = 50 miles, how many miles do 3 3/8 inches represent?
Korvikt [17]
Hey there Fish Girl!

So, if \left[\begin{array}{ccc}1/4 \end{array}\right] equals 50 miles, then we would do this multiplied by . . . . 

So, if we would want to go to 3 whole, we would then have to go to the number 3 of course. So then, we do \left[\begin{array}{ccc}4*3=12\end{array}\right] and then from this, we would have to multiply this my 50.

The reason to why we would have to do this is because 1/4 of a mile is 50, so then, sense we are trying to get to the number 3, then, from doing this,we would determine a figure out how many miles this would conclude to be.

\left[\begin{array}{ccc}12*50\end{array}\right]   =\left[\begin{array}{ccc}\boxed{\boxed{600}} \ so \ far!\end{array}\right]

So, now, we have covered 3 as a whole, then we would have to see how 3/8 and also 1/4 can relate to each other.

So, in this case,\boxed{\boxed{ \frac{3}{8} \ would \ be \ almost \ \boxed{half} \\ \ because \ it \ is \ almost  \frac{4}{8} }}

So, most likely, it would stay the same as it is, 1/4 because this is almost half to.

SO ALL WE WOULD NEED TO DO NOW IS TO ADD . . . . . 

\left[\begin{array}{ccc}\left[\begin{array}{ccc}\boxed{\boxed{600+50 \ or  \frac{1}{4}=650}} \end{array}\right]\end{array}\right]

YOUR CORRECT AND FINAL ANSWER TO THIS QUESTION WOULD BE. . . . 

\left[\begin{array}{ccc}650 \ miles\end{array}\right]

Hope this helps you fish Girl! :)

<h3>Answer:  Approximately 191 bees</h3>

================================================

Work Shown:

One way to express exponential form is to use

y = a*b^x

where 'a' is the initial value and 'b' is linked to the growth rate.

Since we're told 34 bees are there initially, we know a = 34.

Then after 4 days, we have 48 bees. So we can say,

y = a*b^x

y = 34*b^x

48 = 34*b^4

48/34 = b^4

24/17 = b^4

b^4 = 24/17

b = (24/17)^(1/4)

b = 1.090035

Which is approximate.

The function updates to

y = a*b^x

y = 34*(1.090035)^x

------------------------

As a way to check to see if we have the right function, plug in x = 0 and we find:

y = 34*(1.090035)^x

y = 34*(1.090035)^0

y = 34*(1)

y = 34

So there are 34 bees on day 0, ie the starting day.

Plug in x = 4

y = 34*(1.090035)^x

y = 34*(1.090035)^4

y = 34*1.4117629

y = 47.9999386

Due to rounding error we don't land on 48 exactly, but we can round to this value.

We see that after 4 days, there are 48 bees.

So we confirmed the correct exponential function.

------------------------

At this point we can find out how many bees there are expected to be after 20 days.

Plug in x = 20 to get

y = 34*(1.090035)^x

y = 34*(1.090035)^20

y = 190.672374978452

Round to the nearest whole number to get 191.

There are expected to be roughly 191 bees on day 20.

The total travel time for the ranger to get to the car is the sum of the travel time in the forest and the travel time on the ro
Yuki888 [10]

Answer:

[ext]T(x) = 2C / Speed[/ext]

Step-by-step explanation:

[ext]Time taken for the Ranger to get to the car = Sum total time taken to travel in the forest and on the road[/ext]

Since [ext]distance of the Ranger to the car = C[/ext]

[ext]Time taken = distance/speed[/ext]

[ext]Total Time taken T(x) = 2 * C / speed[/ext]

T(x) = 2C / speed
