The number of gigabytes that Sydney can use while staying within her budget is less than 2.9 gigabytes.
<h3>What are
gigabytes?</h3>
gigabytes (GB) – pronounced with two hard Gs – is a unit of storage capacity equal to approximately 1 billion bytes. In decimal form (base 10), a gigabyte is exactly one billion bytes. In binary form, a gigabyte is 230 bytes or 1,073,71,82 bytes. Giga comes from the Greek word for giant. Werner Buchholz is credited with coining the term byte in 1956 and helped design IBM's 7030 Stretch, the first transistorized supercomputer.
gigabytes has been a common unit of measurement for data storage products since the mid-1980s. In recent years, terabytes (TB) have become a more common measure of storage capacity, especially for hard drives and solid-state drives.

Answer:
B!
Step-by-step explanation:
7.5 i believe. not very good at math tho lol
Answer:
(1) length AB = 21.0
(2) length BC = 45.0
Step-by-step explanation:
(1) To determine AB, apply Cosine rule;
![|AB|^2 = |AC|^2 + |BC|^2 \ - \ 2[|AC| \times |BC]cos \ C\\\\|AB|^2 = 13^2 + 29^2 \ - \ 2(13 \times 29) cos(41)\\\\|AB|^2 = 1010 - 569.05\\\\|AB|^2 = 440.95\\\\|AB|= \sqrt{ 440.95} \\\\|AB| = 21.0](https://tex.z-dn.net/?f=%7CAB%7C%5E2%20%3D%20%7CAC%7C%5E2%20%2B%20%7CBC%7C%5E2%20%5C%20-%20%5C%202%5B%7CAC%7C%20%5Ctimes%20%7CBC%5Dcos%20%5C%20C%5C%5C%5C%5C%7CAB%7C%5E2%20%3D%2013%5E2%20%2B%2029%5E2%20%5C%20-%20%5C%202%2813%20%5Ctimes%2029%29%20cos%2841%29%5C%5C%5C%5C%7CAB%7C%5E2%20%3D%201010%20-%20569.05%5C%5C%5C%5C%7CAB%7C%5E2%20%3D%20440.95%5C%5C%5C%5C%7CAB%7C%3D%20%5Csqrt%7B%20440.95%7D%20%5C%5C%5C%5C%7CAB%7C%20%3D%2021.0)
(2) To determine BC, also apply cosine rule;
![|BC|^2 = |AB|^2 + |AC|^2 \ - \ 2[|AB| \times |AC]cos \ A\\\\|BC|^2 = 30^2 + 21^2 \ - \ 2(30 \times 21) cos(123)\\\\|BC|^2 = 1341 - (-686.245)\\\\|BC|^2 = 1341 + 686.245\\\\ |BC| = 2027.245\\\\|BC|= \sqrt{ 2027.245} \\\\|BC| = 45.0](https://tex.z-dn.net/?f=%7CBC%7C%5E2%20%3D%20%7CAB%7C%5E2%20%2B%20%7CAC%7C%5E2%20%5C%20-%20%5C%202%5B%7CAB%7C%20%5Ctimes%20%7CAC%5Dcos%20%5C%20A%5C%5C%5C%5C%7CBC%7C%5E2%20%3D%2030%5E2%20%2B%2021%5E2%20%5C%20-%20%5C%202%2830%20%5Ctimes%2021%29%20cos%28123%29%5C%5C%5C%5C%7CBC%7C%5E2%20%3D%201341%20-%20%28-686.245%29%5C%5C%5C%5C%7CBC%7C%5E2%20%3D%201341%20%2B%20686.245%5C%5C%5C%5C%20%7CBC%7C%20%3D%202027.245%5C%5C%5C%5C%7CBC%7C%3D%20%5Csqrt%7B%202027.245%7D%20%5C%5C%5C%5C%7CBC%7C%20%3D%2045.0)
