The circled ones are like terms so 6+(-8)+5 which is 3and then answer is 12x+3
hope this helps!:)
Answer:
Volume = 1099 cm³
Step-by-step explanation:
Volume = πr²h = 3.14(5²)(14) = 1099 cm³
Solution:
We are given:
μ=60
σ=15.9
n=40
Therefore, the z-statistic is 1.19
so, the repairman charges $45 for each hour of work, and $44 for the parts, now the parts are obtained only once, so that's a one-time charge of 44 bucks, let's see how the hours go.
1 hour of work................... 45 + 44(1)
2 hours of work................45 + 44(2)
3 hours of work................45 + 44(3)
4 hours of work................45 + 44(4)
x hours of work................45 + 44(x)
so the cost equation, with x = hours, C(x) = 45 + 44x.
what is x if C(x) = 179?
