Since x & y vary inversely  (it means when x increases, y decreases & vice versa)
Then the equation==> y = k/x (k is a constant to be calculated)

But x=9 and y=3 (given) ==> 3=k/9 or k=27 & the equation becomes y=27/x

The Farmer Supply is building storage building for fertilizer shaped top. The that has cylindrica base and cone county laws say
creativ13 [48]

Assuming  ℎ1 = 11 feet and ℎ 2 = 3 feet, the storage of the facility is going to be 603 cubic feet, which is more than 576 cubic feet

The diameter of the building has been given as 8cm

radius = d/2 = 8/2 = 4

Maximum height = h1 + h2 = 14

Find the volume of the fertilizer that is containeed in both of the trucks

2(12x4x6) = 576 feet

From the height of 14 feets we have to assume

h1 = 11 ft,

h2 = 3 ft

<h3>How to solve for volume</h3>

volume =\frac{1}{3} \pi r^{2} h2 + \pi r^{2} h1

= 0.333*3.14*4²*3 + 3.14*4²*11

= 602.8 ft ≈ 603

-4(x-4)=-44<br> Please answer this with how you got the answer.
devlian [24]

Answer: x = -15

Step-by-step explanation:

Think PEMDAS

First, we factor the parenthesis:

-4 (x-4) = -4(x) + -4(-4)

now we are left with -4x + 16 = -44

Next is to isolate the "x":

to do this, we must subtract 16 from -44

-44 - 16 = 60

now we have -4x = 60

Now we divide both sides by -4 in order to isolate "x"

dividing -4x/-4 = x

diving 60/-4 = -15

the answer is x= -15
