Answer: 49+64i
Step-by-step explanation:
Concept to know:
i=√-1
i²=-1
i³=-i
=1
-------------------------------------
(-5+8i)(3-8i)
=-15+40i+24i-64i²
=-15+64i-64i²
=-15+64i+64 (remember, i²=-1)
=49+64i
Hope this helps!! :)
Please let me know if you have any question or need further explanation
8 blocks because 2/10=1/5 so if they total 4/5 then 2/10+2/10+2/10+2/10=8/10=4/5
2 ft 9 in
4 ft 8 in
6 ft 11 in

12 ft 28 in
12 inches = 1 ft....so 28 inches = 2 ft 4 inches

Answer:
800 students surveyed by Kureshi responded that they have a part time job.
Step-by-step explanation:
<u>Miguel's Survey:</u>
Total students surveyed = 750
Number of students doing part time job = 500
So, the ratio of Total Students : Students doing part time = 750: 500 ... (1)
<u>Kureshi's Survey:</u>
Total students surveyed = 1200
Let Number of students doing part time job = m
So, the ratio of Total Students : Students doing part time = 1200 : m ... (2)
Now, the ratio in (1) and (2) are equal:

or, m = 800
Hence, 800 students surveyed by Kureshi responded that they have a part time job.
