Answer:

$y=1.44$

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

<u>Step 1: Define</u>

<u /> $\frac{4.5}{y} =\frac{12.5}{4}$ <u />

<u />

<u>Step 2: Solve for </u><em><u>y</u></em>

Cross-multiply: $4(4.5) = 12.5y$
Multiply: $18 = 12.5y$
Isolate <em>y</em>: $1.44 = y$
Rewrite: $y=1.44$

<u>Step 3: Check</u>

<em>Plug in y to verify it's a solution.</em>

Substitute: $\frac{4.5}{1.44} =\frac{12.5}{4}$
Divide: $3.125=3.125$

Here, we see that 3.125 does indeed equal 3.125. ∴ y = 1.44 is a solution of the equation.

from a thin piece of cardboard 40 in by 40 in, square corners are cut out so that the sidescan be folded up to make a box. What

laiz [17]

Answer:

20- max volume dimension

Step-by-step explanation:

since we don't know the amount of cardboard cut off, we'll take it as "x"^^

so the bottom of the box have dimensions of 40-2x(since squares are cut from both corners in a side) by 40-2x hence we can take area of base as

(40-2x)^2

since v=base*height

lets take height as x

x(40-2x) (40-2x)=v

(40x-2x^2)(40-2x)=v

4x^3-160x^2+1600x=v

take the derivitive: 12x^2-320x+1600

factor:

4(3x^2-80x +400)=0

4(3x-20)(x-20)=0

12x-80=0

x-20=0

x=20, 6.667(reduced from 6.66666666667)
