Answer:

x = 3.76 ft

Step-by-step explanation:

To find the missing side, "x", solve using proportions.

In similar polygons, the 'new' polygon was created by multiplying every side of the 'old' polygon by the same number. Every side was multiply by the <u>scale factor</u>, "k", which tells you how much a polygon grew (k>1) or shrunk (0<k<1).

Therefore, if you divided the pairs of corresponding sides, they would be equal.

From the diagram, you can tell that the following sides correspond:

CB ~ GF

AB ~ EF

<u>Use the proportion</u>

\frac{EF}{AB} = \frac{GF}{CB}

\frac{x}{6ft} = \frac{3.3ft}{5ft}      Substitute values from diagram

6ft*\frac{x}{6ft} = 6ft*\frac{3.3ft}{5ft}       Multiply both sides by 6 ft

x = \frac{6ft*3.3ft}{5ft}        "x" is isolated. Multiply fraction by combining into numerator

x = \frac{19.8ft}{5ft}        Solved numerator. Divide for decimal answer.

x = 3.76ft

The value of 'x' is 3.76 ft.

Hola User______________

Here is your Answer...!!

______________________

The time relation equation will be ...

1) t = 64 (0.5)^r

since it can be proved , by placing values of r

thus as

1) r=0 ; t = 64
2) r=1 ; t = 32
3) r=3 ; t = 16

and so on...

During a rainstorm a pail collects 1/3 of an inch of water in 5/6 of a minute. At what rate is the pail collecting water?
Delicious77 [7]

Answer:

2/5 of an inch per minute

Step-by-step explanation:

You can set up the rate as  \frac{1/3}{5/6}.  From here to find the amount of rain per minute, just multiply the numerator and denominator by 6/5 (The reciprocal of 5/6, so you can have one minute and see how much rains fills up in that time.)

You end with 2/5 of and inch per minute
