Step-by-step explanation:

19/9 = 2.1111111111

<h2>so to round to the nearest thousandth means there should be 3 numbers after the decimal point (.) because a thousandth contains 3 zeros.</h2>

2.11111111111 to the nearest thousandth = 2.111

Hope this helps.

Good luck ✅.

#3 Which of the following is less than 527 m?

A. 0.000699 Mm = 0.000699 · 1,000,000 m = <u>699 m</u>

B. 914,879,710 nm = (914,879,710 : 1,000,000,000) m = <u>0.914879710 m</u>

C. 51,723 cm = (51,723 : 100) m = <u>517.23 m</u>

The best answer is C

#4 How many songs would you have if the average file size is 4,000 kb?

8 gb: 1,700 songs

16 gb: 6,000 songs

2 gb: 500 songs

160 gb: 30,000 songs

64 gb: 14,000 songs

1 Terabyte = 1024 gb: so im guessing 350,000 songs

This depends on the length of the song and the file format/type. A typical mp3 song of around 4 minutes averages 4 MB (4000 KB).

Calculate the length b to two decimal places.

Andrej [43]

Answer:

B. 21.64

Step-by-step explanation:

We have been given a triangle and we are asked to find the length of AC (b).

We will use law of cosines to find the length of side AC.

$c^{2}=a^{2}+b^{2}-2ab \text{ cos }\theta$

Upon substituting our given values in the formula we will get,

$(AC)^{2}=15^{2}+12^{2}-2\times 15\times 12 \text{ cos}(106)$

$(AC)^{2}=225+144-360\text{ cos}(106)$

$(AC)^{2}=369-360(-0.275637355817)$

$(AC)^{2}=369+99.22944809412$

$(AC)^{2}=468.22944809412$

Upon taking square root of both sides of our equation we will be get,

$AC=\sqrt{468.22944809412}$

$AC=21.6386101238993629\approx 21.64$

Therefore, the length of b is 21.64 and option B is the correct choice.
