Answer:
12.5%
Step-by-step explanation:
A + k = 600
k = 2/3a
a + 2/3a = 600
3/3a + 2/3a = 600
5/3a = 600
a = 600 * 3/5
a = 1800/5
a = 360
k = 2/3a
k = 2/3(360)
k = 720/3
k = 240
so Kim's pay is $ 240 and Alicia's pay is $ 360
Answer:
There will be 135 squares in total. Changing the order of the factors wont change the result.
Step-by-step explanation:
(i am assuming that sqaures = sqaure pieces)
Each section has 3 rows of 15 square pieces, therefore each section has 3*15 = 45 sqaure pieces. Thus, the complete guilt will have 45*3 = 135 square pieces. Since all we do were multiplications, changing the order of the factors wont change the value of the product.

Step-by-step explanation:
With the information given, let's consider some aspects of Sandy Beach behavior.
1. Sandy Beach
Let's calculate the period of this function
The Period of sin function is 
2. Verifying the Range, in this case the lapse of time.
A <em>sin</em> function varies from -1 to 1, i.e.
![-1\leq sin(s) \leq1 \therefore-4\leq 4sin(s)\leq4 \\ adding \:the\:5\\-4+5\leq 4sin(s)\leq4+5\\\\\1\leq4sin+5\leq9 \therefore t=[1,9]\\](https://tex.z-dn.net/?f=-1%5Cleq%20sin%28s%29%20%5Cleq1%20%5Ctherefore-4%5Cleq%204sin%28s%29%5Cleq4%20%5C%5C%20adding%20%5C%3Athe%5C%3A5%5C%5C-4%2B5%5Cleq%204sin%28s%29%5Cleq4%2B5%5C%5C%5C%5C%5C1%5Cleq4sin%2B5%5Cleq9%20%5Ctherefore%20t%3D%5B1%2C9%5D%5C%5C)
So, within an interval form 1 to 9 hours the waves at Sandy Beach come and go.
