Hey!
The formula of direct variation is y = kx. So we know that p = kr^2
Hint: after it says varies, it's basically the equal sign.
so we can set it up
56 = 4^2k
56=16k
now we want k alone so we have to divide 16 on both sides
k=3.5
We can now solve for p like it asks
p = 3.5*6^2
p=126
There's your answer!
Hope this helps!
Seed mix a is more expensive than b
This type of keg contains the equivalent of 165 12 fluid ounces cans of beer. It's about half as big as a Bathtub. In other words, 2,560 fluid ounces is 0.47 times the size of a Bathtub, and the size of a Bathtub is 2.1 times that amount. The capacity of a typical bathtub is 5,400 fluid ounces.
Answer:
y = 6.
Step-by-step explanation:
z = kx/y
9 = k*24/8
24k = 72
k = 3.
So z = 3x/y
When x = 10 and z = 5
5 = 3*10/y
5y = 30
y = 6.
Y=mx+b
solve for b
-11=-3*1/2+b
-11=-1.5+b
b=-11+1.5
b=-9.5
