The scale factor of a model of a swimming pool to the actual swimming pool is 1 to 20. The
denis23 [38]

Answer:

0.05\ m^3

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z ----> the scale factor

x ---> the volume of the model of a swimming pool

y ---> the volume of the actual swimming pool

so

z^3=\frac{x}{y}

we have

z=\frac{1}{20}

y=400/ m^3

substitute

(\frac{1}{20})^3=\frac{x}{400}

solve for x

\frac{1}{8,000}=\frac{x}{400}

x=\frac{400}{8,000}

x=0.05\ m^3

Simplify and solve for d. 1/6d+2/3=1/4(d-2)
Dvinal [7]
1/6d + 2/3 = 1/4(d - 2)
1/6d + 2/3 = 1/4d -1/2
2/12d + 4/6 = 3/12d -3/6
4/6 = 1/12d - 3/6
7/6 = 1/12d
7/6 x 12/1 = d
84/6 = d
14 = d

So d = 14.

Hope I helped.. ^^
