8. The trapezoids are similar. The area of the smaller trapezoid is 131 m2. Find the area of the larger trapezoid to the nearest

kolbaska11 [484]

Answer:

$3,726\ m^{2}$

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor

Let

z----> the scale factor

x----> corresponding side of the larger trapezoid

y----> corresponding side of the smaller trapezoid

$z=\frac{x}{y}$

we have

$x=64\ m$

$y=12\ m$

substitute

$z=\frac{64}{12}$

step 2

Find the area of the larger trapezoid

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z----> the scale factor

x----> area of the larger trapezoid

y----> area of the smaller trapezoid

$z^{2}=\frac{x}{y}$

we have

$z=\frac{64}{12}$

$y=131\ m^{2}$

substitute

$(\frac{64}{12})^{2}=\frac{x}{131}$

$x=(\frac{4,096}{144})(131)$

$x=3,726\ m^{2}$

Solve for x please for 10 points

Ira Lisetskai [31]

Answer:

$\frac{x-2}{2+1}=\frac{4x-5}{3}$

$\frac{x-2}{3} =\frac{4x-5}{3}$

$3*\frac{x-2}{3} =\frac{4x-5}{3}*3$

$x-2=4x-5$

$x-2+5=4x-5+5$

$x-x+3=4x-x$

$3=3x$

$\frac{3}{3} =\frac{3x}{3}$

$1=x$

Your friend says that 14.5% is equivilent to 14.5

SCORPION-xisa [38]

14.5% = 0.145 = 145/1000

14.5 = 14500/1000

<span>So 14.5% is a hundredth the size of 14.5, so they are not equal and the friend is incorrect.</span>
