86.77 is the answer u divide 549,120 by 31,000 then use the tan
Answer:
Step-by-step explanation:
![\sqrt[3]{x+4}+\sqrt[3]{2x +8}=0\\\\\sqrt[3]{x+4}= -\sqrt[3]{2x + 8}\\\\(x +4)^{\frac{1}{3}}=-(2x+8)^{\frac{1}{3}}\\\\](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%2B4%7D%2B%5Csqrt%5B3%5D%7B2x%20%2B8%7D%3D0%5C%5C%5C%5C%5Csqrt%5B3%5D%7Bx%2B4%7D%3D%20-%5Csqrt%5B3%5D%7B2x%20%2B%208%7D%5C%5C%5C%5C%28x%20%2B4%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%3D-%282x%2B8%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%5C%5C%5C%5C)
Take cube,
![[(x+4)^{\frac{1}{3}}]^{3} =- [(2x +8)^{\frac{1}{3}}^{3}]\\\\(x+4)^{3*\frac{1}{3}}=-(2x + 8)^{3*\frac{1}{3}}\\\\](https://tex.z-dn.net/?f=%5B%28x%2B4%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%5D%5E%7B3%7D%20%3D-%20%5B%282x%20%2B8%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%5E%7B3%7D%5D%5C%5C%5C%5C%28x%2B4%29%5E%7B3%2A%5Cfrac%7B1%7D%7B3%7D%7D%3D-%282x%20%2B%208%29%5E%7B3%2A%5Cfrac%7B1%7D%7B3%7D%7D%5C%5C%5C%5C)
x + 4 = - (2x + 8)
x +4 = 2x *(-1) + 8 *(-1)
x+ 4 = -2x - 8
x +2x+4 = - 8
3x + 4 = - 8
3x = - 8 -4
3x = -12
x = -12/3
x = -4
11/20 < 61%
11/20 =.55
61% = .61
.55<.61

Answer:
N(h) = 2h + 6
Step-by-step explanation:
A model of the number of people that Denis can invite to his party:
N(x) = x/25.............(1)
Where x = amount of money saved
Amount of money saved can be modeled by the equation:
M(h) = 50h + 150...........(2)
In the above model, h = number of overtime hours
M(h) = amount of money saved = x
Therefore equation (1) can be re - written as:
N(x) = M(h)/25.................................(3)
Substituting equation (2) into equation (3)

Find an explicit expression that models the number of people that Denis can invite to his party if he worked h overtime hours this week can be expressed as:
N(h) = 2h + 6
