The chef has 3636 pounds of strip loin steak. The amount of weight lost from the trim on each pound is 35\%35%, and 75\%75% more
OLEGan [10]

Answer:

The remaining weight of strip loin steak is 5.85 pounds.

Step-by-step explanation:

It is given that the chef has 36 pounds of strip loin steak. The amount of weight lost from the trim on each pound is 35%, and 75% more of the steak's weight is lost after cooking it.

The weight lost from the trim on each pound is 35%. So, 35% of 36 is

36\times \frac{35}{100}=12.6

The remaining weight after trim is

36-12.6=23.4

The 75% more of the steak's weight is lost after cooking it. So, 75% of remaining weight is

23.4\times \frac{75}{100}=17.55

The remaining weight after cooking is

23.4-17.55=5.85

The remaining weight of strip loin steak is 5.85 pounds.

harina [27]
Mid point b/w pair of coordinate (xo ,yo) ,(x1,y1)
X = xo+x1/2
y= yo+y1/2
thus mid point between (-8,-8),(4,8)
X = -8+4/2= -2
y= -8+8/2 = 0
(-2,0) will be the midpoint

The steps to derive the quadratic formula are shown below:
prohojiy [21]

Answer:

\huge\boxed{\sf Option \ B}

Step-by-step explanation:

<h3>Step 3:</h3>

\displaystyle x^2+\frac{bx}{a} =\frac{-c}{a} --------------------(1)

<h3>The next step will be:</h3>
  • to find the b² for the expression on the left.
<h3>How to find b²:</h3>

Take the expression

\displaystyle x^2 + \frac{bx}{a}

<u>We can also write it as:</u>

\displaystyle (x)^2 + 2(x)(\frac{b}{2a} )

According to the formula a^2+2ab+b^2, the b of this expression is \displaystyle \frac{b}{2a}. So,

b² will be:

\displaystyle =(\frac{b}{2a} )^2\\\\=\frac{b^2}{4a^2}

So, we will add \displaystyle \frac{b^2}{4a^2} to both sides in Eq. (1)

For STEP 4, the equation will become:

\displaystyle x^2+\frac{bx}{a} + \frac{b^2}{4a^2} = \frac{-c}{a} + \frac{b^2}{4a^2}
