Pls tell me least to greatest 4.5 and 3.9 and 4.258 and 3.75 and 4.256
Darya [45]
3.75, 3.9, 4.256, 4.258, 4.5

So how do you find out? It is really easy.

First you look the the number, we all know 3 is less then 4 so the 3s go first

Then you look the tenths,  the choices are 3.75 and 3.9.  The tenth 9 and 7, and we all know 7 is less then 9, so 3.75 is the first one, then 3.9.

Now let's look at the 4s.  The choices are 4.5, 4.258, and 4.256.  The tenths are 5, 2, and 2.  2 is less then 5 so they go before 4.5.

Then we look at the hundredth, the choices are 4.256 and 4.258.  Since they have same hundreds, we look at the thousands.  They are 6 and 8.  6 is less then 8 so 4.256 go before 4.258.

iVinArrow [24]

Answer:

\frac{15}{16}

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the area of the large square

A=8^2=64\ in^2

step 2

Find the area of the smaller white square

A=2^2=4\ in^2

step 3

Find the area of the blue region

Subtract the area of the smaller white square from the area of the larger square

64-4=60\ in^2

step 4

Find the probability

we know that

To find out the probability that a point chosen at random is in the blue region, divided the area of the blue region by the area of the larger square

so

\frac{60}{64}

Simplify

\frac{15}{16}
