Answer:
The length of the ladder would be 32 feet.
Step-by-step explanation:
In order to find the missing value, we create a proportion. We can do this by making two fractions -- the numerator being the depicted length and the denominator being the actual length.
(1.5/4) = (12/x)
Since we don't know the actual length of the ladder, we put it in as x. Now we can cross multiply to solve.
(1.5/4) = (12/x)
1.5*x = 4*12
1.5x = 48
x = 32
h(x) = x + 7/4
Replace h(x) with y
y = x + 7/4
Swap x and y
x = y + 7/4
Solve for y.
Subtract 7/4 from both sides.
y = x - 7/4
Replace y with h(x)^-1
<h3>h(x)^-1 = x - 7/4</h3>
Answer:
(X+3)(X+8)
Step-by-step explanation:
In the attached file
"The chemical is dispensed to completely fill 25 identical cylindrical containers"
So obviously the volume of each is 1/25 of the whole volume, right? So you know V for one of these cylinders.
"each with a radius of 5 in"
V = pi*r^2*h
<span>You know V. You know r. Plug them in. Solve for h. Should take one line.
</span><span>235,500 /25 = 9420 is the volume of 1 cylinder.
</span>h <span>=</span><span>V/</span><span>π</span><span>r</span><span>2</span><span>
</span>h ≈119.94
