what r the characteristics?
Answer:
20 lbs of 9%
10 lbs of 15%
Step-by-step explanation:
x: 9%
y: 15%
x + y = 30
y = 30 - x
0.09x + 0.15y = 0.11(30)
0.09x + 0.15(30 - x) = 3.3
-0.06x = -1.2
x = 20
y = 10
y = 30 - x
Your answer to your question is A ;)
f(x) is a fancy way to say y
The equation says y=05, so x is ungiven based on what you have given us. Please check if there was more information written as usually its written as
Example: f(x)=3x+5
Answer:
D. 16 times.
Step-by-step explanation:
Volume of a cylinder = π r^2 h
π r^2 h = 432
Now if the diameter is reduced by 1/4 then the radius is reduced by a fourth also.
Let the new height be H, then:
432 = π (r/4)^2 H
so π r^2 h = π(r/4)^2 H
r^2 h = r^2 H / 16
h = H/16
H = 16h.
