Answer:
£2380.23
Step-by-step explanation:
The increase will be 8.5% of £2193.76 added to £2193.76
That’s
8.5% of £2193.76
8.5% /100% x £2193.76
0.085 x £2193.76
£186.47
Increase = £2193.76 + £186.47
= £2380.23
He spent the same amount on each bolt size...so we need to find the lowest common multiple of 0.15, 0.20, and 0.30....and that would be 0.60
so he spent 0.60 on each bolt
Your answer would be 9.37
I hope this helps

Answer:
Check below
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.
3. Check the graph below.
Answer:
Length-65 ft Width: 85
Step-by-step explanation:
Let's set the length as x, and the width as x+20 (because it is 20 ft longer than length)
We know that 2L+2W=Perimeter
We can substitute x and x+20 in for 2L and 2W, and 300 for Perimeter
New Equation: 2(x) +2(x+20)=300
After Distribution: 2x+2x+40=300
Combine like terms: 4x+40=300
Subtract 40 from both sides: 4x=260
Divide 4 on both sides and you get x=65 (Length)
Add 20 to get width : x+20= 85
I hope it helped! :)
