Identify the square root of 3 as either rational or irrational, and approximate to the tenths

1 answer:

7 0

The square root of 3 would be: $\sqrt{x} 3$ I hope that works or you can see it but, you are going to square root the 3 and it will give you 1.73205 etc. and so on.

A rational number can be written as a FRACTION

An irrational number is written as a decimal.

So this would be an irrational number.

To the tenths you would round the tenths spot to the next number if the 100ths number were larger. But its not so you wouldn't change it.

ones. tenths hundredths thousands

1.7 should be your answer

Match each spherical volume to the largest cross sectional area of that sphere

zlopas [31]

Answer:

Part 1) $324\pi\ units^{2}$ ------> $7,776\pi\ units^{3}$

Part 2) $36\pi\ units^{2}$ ------> $288\pi\ units^{3}$

Part 3) $81\pi\ units^{2}$ ------> $972\pi\ units^{3}$

Part 4) $144\pi\ units^{2}$ ------> $2,304\pi\ units^{3}$

Step-by-step explanation:

we know that

The largest cross sectional area of that sphere is equal to the area of a circle with the same radius of the sphere

Part 1) we have

$A=324\pi\ units^{2}$

The area of the circle is equal to

$A=\pi r^{2}$

$324\pi=\pi r^{2}$

Solve for r

$r^{2}=324$

$r=18\ units$

Find the volume of the sphere

The volume of the sphere is

$V=\frac{4}{3}\pi r^{3}$

For $r=18\ units$

substitute

$V=\frac{4}{3}\pi (18)^{3}$

$V=7,776\pi\ units^{3}$

Part 2) we have

$A=36\pi\ units^{2}$

The area of the circle is equal to

$A=\pi r^{2}$

$36\pi=\pi r^{2}$

Solve for r

$r^{2}=36$

$r=6\ units$

Find the volume of the sphere

The volume of the sphere is

$V=\frac{4}{3}\pi r^{3}$

For $r=6\ units$

substitute

$V=\frac{4}{3}\pi (6)^{3}$

$V=288\pi\ units^{3}$

Part 3) we have

$A=81\pi\ units^{2}$

The area of the circle is equal to

$A=\pi r^{2}$

$81\pi=\pi r^{2}$

Solve for r

$r^{2}=81$

$r=9\ units$

Find the volume of the sphere

The volume of the sphere is

$V=\frac{4}{3}\pi r^{3}$

For $r=9\ units$

substitute

$V=\frac{4}{3}\pi (9)^{3}$

$V=972\pi\ units^{3}$

Part 4) we have

$A=144\pi\ units^{2}$

The area of the circle is equal to

$A=\pi r^{2}$

$144\pi=\pi r^{2}$

Solve for r

$r^{2}=144$

$r=12\ units$

Find the volume of the sphere

The volume of the sphere is

$V=\frac{4}{3}\pi r^{3}$

For $r=12\ units$

substitute

$V=\frac{4}{3}\pi (12)^{3}$

$V=2,304\pi\ units^{3}$

The issue of corporate tax reform has been cause for much debate in the United States. Among those in the legislature, 26% are R

Stells [14]

Answer:

<h2>Check the explanation.</h2>

Step-by-step explanation:

Let, the total population is 1000.

The number of republicans are 26% that is 260, Democrats are 63% that is 630 and Independents are 11% of 1000, that is 110.

20% of 260 = $\frac{20\times260}{100} = 52$ Republicans favor some type of corporate tax reform.

51% of 630 = $\frac{51\times630}{100} = 321.3$ .

29% of 110 = $\frac{29\times110}{100} = 31.9$ .

Total number of people, who favor some type of corporate tax is (52 + 321.3 + 31.9) = 404.2 ≅404.

The required probability is $\frac{321}{404}$ .
