Answer:
9 shirts
Step-by-step explanation:
20% of the shirts were blue
20% of 30 is 6
6 shirts were blue
1/2 of the shirts were black
1/2 = 50%
50% of 30 is 15
15 shirts are black
15 + 6 = 21
30 - 21 = 9
(or you could add the percentages to get 70%, and get 30%. 30% of 30 is 9.)
Hope this helps!
Answer:
Let the length be l, width w and height h, then
Volume = length x width x height
l = 10cm, w + h = 18cm
V(h) = 10(18 - h)h = 180h - h^2
V(h) = 180h - h^2
Step-by-step explanation:
Answer: f(6) = (6)2 + 1 = 36 + 1 = 37
If we wanted to find and expression for f(g(x)) we could plug in g(x), which is "x - 4" into the function f(x) wherever we see an "x". So:
f(x) = x2 + 1
f(g(x)) = (x - 4)2 + 1 because g(x) is "x - 4"
