So hmm the food C = 6p + 3q  and the food D = 4.5p + 1.5q

now, if we check how much is the ratios of C/D for each component, then, mixture M = 144p + 60q, must contain the same ratio for each "p" and "q" component

\bf \textit{ratio of "p"}\implies \cfrac{6}{4.5}\implies \cfrac{4}{3}
\\\\\\
\textit{ratio of "q"}\implies \cfrac{3}{1.5}\implies \cfrac{2}{1}

so, if we divide the 144p by 4+3, or 7 even pieces, 4 must belong to food C and 3 to food D, retaining the ratio of 4/3

and we do the same for 60q, we divide it in 2+1 or 3 even pieces, but that one is very clear, 2 must belong to food C and 1 to food D, 60/3 is clear ends up with a ratio of 40 and 20

now the "p" part... ends up as \bf \cfrac{144}{7}\cdot 4\qquad and\qquad \cfrac{144}{7}\cdot 3\implies \cfrac{576}{7}\qquad and\qquad \cfrac{432}{7}

that's what I see it, as the ratio of 4/3 and 2/1 being retained in the mixture M

Answer:

\frac{5 {x}^{2}  + 20xy + 20 {y}^{2} }{x ^{2} - xy -  {6y}^{2}  }

To simplify first factorize both the numerator and the denominator

For the numerator

5x² + 20xy + 20y²

Factor 5 out

5 ( x² + 4xy + 4y²)

Using a² + 2ab + b² = ( a + b)²

The numerator is

5( x + 2y)²

For the denominator

x² - xy - 6y²

Rewrite -xy as a difference

x² + 2xy - 3xy - 6y²

Factorize

We have the denominator as

( x + 2y)( x - 3y)

So we now have

<h2>\frac{5(x + 2y)(x + 2y)}{(x + 2y)(x - 3y)}</h2>

Simplify

<h2>\frac{5(x + 2y)}{x - 3y}</h2>

We have the final answer as

<h2>\frac{5x + 10y}{x - 3y}</h2>

Hope this helps you

Elza [17]

Answer:

84 cm^3

14080 cm^3

81 cm^3

Step-by-step explanation:

Remember the formulas for volume, and you're golden.

a) V(prism) = area of base * height

                  = 12 cm^2 * 7 cm = 84 cm^3

b) V(prism) = area of base * height

                  = 88 cm^2 * 160 cm = 14080 cm^3

c) V(cylinder) = area of base * height

                      = 54 cm^2 * 1.5 cm = 81 cm^3
