Answer:
See below in bold.
Step-by-step explanation:
Total = A(1 + r/n)^nt where A = initial amount , t = number of years, r = the rate (as a decimal fraction) and n = number of payments a year. So:
Total after 1 year = 8000(1 + 0.09/2) ^ 1*2
= RS 8736.20.
Compound interest = RS 736.20
Answer: you subtract the angles by the one you are trying to solve

Answer:
m=-5/2
Step-by-step explanation:
Use the slope-intercept form y=mx+b to find the slope m.
Answer:
16 shirts and 48 ties
Step-by-step explanation:
you start with 64 and divide it by 4 i got four cause it says that James had THREE times as many ties as shirts leaving him with leaving him with 3 groups of ties and 1 group of shirts . dividing 64 by 4 leaves you with 16 which is the amount of shirts he has and then you would multiply 16 by 3 to get the amount of ties he has.
Step-by-step explanation:
The way to find missing numbers in equivalent ratios is to multiply the means (the first denominator and the second numerator) and multiply the extremes (the first numerator and the second denominator). It sounds really complicated, but it is quite simple =)
2/5 = x/10
The means in this equivalent ration are 5 and x. The extremes are 2 and 10.
5x = 20
Now solve =)
x = 4
That was pretty simple. Let's move on to the next one. Do exactly the same thing here:
4/10 = 6/x
60 = 4x
15 = x
That was pretty simple, too! Keep going!
6/15 = x/25
15x = 150
x = 10
All of these should be equal, so check them by dividing:
2/5 = 0.4
4/10 = 0.4
6/15 = 0.4
10/25 = 0.4
They all check out, so these are your answers: 2/5, 4/10, 6/15, 10/25
I really hope this helps you =)
