In 25 minutes Jezebel can run 10 laps around the track. Part I) Determine the unit rate for the number of laps she can run per m

Cloud [144]

Answer: See explanation

Step-by-step explanation:

a. Determine the unit rate for the number of laps she can run per minute.

This will be calculated as the number of minutes used divided by the number of laps which will be:

= 25 / 10

= 2.5 minutes per lap.

b. Find the constant of proportionality for this situation.

We will use the formula y = kx

where y = 25, x = 10, k = constant of proportionality.

Therefore, y = kx

25 = 10k

k = 25/10

k = 2.5

The constant of proportionality is 2.5

Answer:

$\large\boxed{\dfrac{x^3+6x}{80x+64}}$

Step-by-step explanation:

$\dfrac{\frac{1}{8}+\frac{x+4}{16}}{\frac{x+4}{x^2}+\frac{4}{x}}=\left(\dfrac{1\cdot2}{8\cdot2}+\dfrac{x+4}{16}\right):\left(\dfrac{x+4}{x^2}+\dfrac{4\cdot x}{x\cdot x}\right)\\\\=\left(\dfrac{2}{16}+\dfrac{x+4}{16}\right):\left(\dfrac{x+4}{x^2}+\dfrac{4x}{x^2}\right)=\dfrac{2+x+4}{16}:\dfrac{x+4+4x}{x^2}\\\\=\dfrac{x+6}{16}:\dfrac{5x+4}{x^2}=\dfrac{x+6}{16}\cdot\dfrac{x^2}{5x+4}=\dfrac{(x+6)(x^2)}{(16)(5x+4)}\\\\\text{use distributive property}\ a(b+c)=ab+ac$

$=\dfrac{(x)(x^2)+(6)(x)}{(16)(5x)+(16)(4)}=\dfrac{x^3+6x}{80x+64}$
