Answer:

I’m curious about the dimensions of a pizza where the width exceeds the height by 9 inches, and the area totals 250 square inches.

My brother is inquiring about the length of his bed, which covers an area of 2m² with a width that is .5m larger than the height.

My father wants the dimensions of a football field that has an area of 57,600 square feet, knowing that the length is 200 ft greater than the width.

Explanation:

In order to tackle this, represent the unknowns as "X". For the pizza case, we don't know the width or the height, but we know their relationship. If we let "x" denote the height, then the width becomes "x+9". The multiplication of these two variables equates to the area.

x(x+9)=250\\x^{2} +9x=250\\x^{2} +9x-250=0\\

Proceed to solve the others similarly.

Regarding the bed, it has an area of 2m² and the height is designated as "x".

x(x+-5)=2\\x^{2} +.5x=2\\x^{2} +.5x-2=0\\

Lastly, my father seeks the dimensions of a football field with an area of 57,600 square feet, where the width is represented as "x".

x(x+200)=57,600\\x^{2} +200x=57,600\\x^{2} +200x-57,600=0\\

Mariulka [3825]
The raw materials price variance amounts to $14,016 favorable. The calculation for this variance is done as follows: = Actual Quantity × (Standard Price - Actual Price) = 23,360 liters × ($5.40 - $4.80) = 23,360 liters × $0.6 = $14,016 favorable This is derived by taking the standard price, subtracting the actual price, and multiplying the difference by the actual quantity to arrive at the finalized value.
