Answer:
0.02826855123 or 35.37
Step-by-step explanation:
24/849 = 0.02826855123
849/24 = 35.37
I am not too sure I understand the question or that we know enough.
Does the "refused" cofee go to the next person? Do they still prepare it and if yes, does it count as "distributed?
As far as I can see it now: from what we know they disrtibute 16-12=4 so only four copies. This is the best answer i can give with the information given.
Start by doing a subtraction of 6 to both sides so that the equation becomes -2x^2 + 7x + 1 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -7 ± √((7)^2 - 4(-2)(1)) ] / ( 2(-2) )
x = [-7 ± √(49 - (-8) ) ] / ( -4 )
x = [-7 ± √(57) ] / ( -4)
x = [-7 ± sqrt(57) ] / ( -4 )
x = 7/4 ± -sqrt(57)/4
The answers are 7/4 + sqrt(57)/4 and 7/4 - sqrt(57)/4.
Answer:
y=45x+20
Step-by-step explanation:
y=45x+20
45 is constant, so every hour it takes, 45 dollars will be added (slope)
20 is the starting point (y- intercept)
Using formula y=mx+b
y=45x+20
Answer:
4.5z^(3.5) -6.5z^(-1.5)
Step-by-step explanation:
I find it easier to write this as the sum of two terms and use the power rule.
f = z^(4.5) +13z^(-0.5)
f' = 4.5z^(3.5) -6.5z^(-1.5)
