11 skirts since you can use 3/4 on each yard of 9. Then you get a remander of 2, 3/4! 9 + 2 is 11.
Answer:
32
Step-by-step explanation:
16,000 = (2^7)(5^3)
So, the number of positive divisors of 16,000 = (7+1)(3+1)
= (8)(4)
Answer:
x^2 - 30 + 224 ≥ 0
the amount of cookies Jessica has more than Martha is at least two
Step-by-step explanation:
J + M = 30
x - 12 < 80
Domain:
f(x) has a denominator, which can't be zero. So, its domain is given by
g(x) has a denominator as well. Moreover, it has a root. So, the content of the root can't be negative:
And the denominator can't be zero:
So, the domain is
Composition:
We have
The domain of this function is
But we also have to remember about the domain of g(x): if g(x) is undefined, we can't compute f(g(x))!
So, the domain of f(g(x)) is
2/5 is equivalent to 0.4 or to 4/8 (for example).
