Answer:

Step-by-step explanation:
The triangle is a right triangle.
We can use trigonometric functions to solve the problem.
tan θ = opp/adj
tan 30 = y/(4√3)
y = 4√3 tan 30
y = 4
The 2 like terms are 400km +924m
Answer:
b=-5
Step-by-step explanation:
Divide by -9 to eliminate the -9 on -9b
(Since -9b is the same thing as -9 times b we can use the inverse of multiplication which is division to eliminate the -9 from b but we need to do it on both sides to make it balance)
-9b/-9=45/-9
b=-5
Answer:
Step-by-step explanation:
Find, find the total increase in salary for 7 years;
If 1 year = $4,000
7 years = ?
=7*4000
=28,000 in total
Original salary = $169,300
Add the total increase in salary to the original salary;
169,300 + 28,000 = 197,300
Therefore, in 7 years, the salary would be $197,300
You can solve this by doing 8×8×6 which gives you 384. Since we are finding the volume, you would do length times with times height. Hope this helps :-)
