Answer:
w = ±![\sqrt[4]{36/5}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B36%2F5%7D)
Step-by-step explanation:
-8+5w^4=28
You can regroup it:
5w^4 - 8 = 28
Add 8 to both side:
5w^4 = 28 + 8
5w^4 = 36
Divide both side by 5:
5w^4/5 = 36/5
w^4 = 36/5 
Take the 4 root of both sides:
w = ±![\sqrt[4]{36/5}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B36%2F5%7D)

The question is find the equation, in the function and standard notations, that represent the amount spent in the range of 0 to 5 rides.
Constant cost: $30
Independent variable, number of rides: r
Variable cost: $2r
Total spend, s(r): 30 + 2r
Function: s(r) = 30 + 2r, for 0 ≤r ≤ 5  ----- this is the function notation
Standard form: s(r) is the dependent variable = s
s = 30 + 2r => s - 2r = 30 => 
s + (-2)r = 30, for 0 ≤ r ≤ 5 ------ this is the standard form
        
             
        
        
        
Answer:
A. 12.25 tons
Step-by-step explanation:
We will let x represent the amount required to cover the entire wall. 
We can divided 2/5 by 5/6 to solve for x
2/5 divided by 5/6=x
When you divide by a fraction, you can always multiply by the reciprocal (flipped number). 
Our new equation is:
2/5·6/5=12/25
