we know that having similar triangles so the ratio of sides,area and volume are same.

$s/s=s^2/s^2$

we know that $s^2$ will be the area of triangle.

$s^2/s^2=75/12$

so $s/s=\sqrt{75/12}$

so the ratio of the perimeter of two triangles will be

$(s+s+s)/(s+s+s)=(\sqrt{75} +\sqrt{75} +\sqrt{75} )/(\sqrt{12}+\sqrt{12} +\sqrt{12} )$

ratio of the perimeter= $\sqrt{225} /\sqrt{36}$

The first false statement in the proof as it stands is in Line 5, where it is claimed that a line of length 2.83 is congruent to a line of length 4.47. This mistake cannot be corrected by adding lines to the proof.

_____

The first erroneous tactical move is in Line 4, where the length of DE is computed, rather than the length of FD. This mistake can be corrected by adding lines to the proof.

A correct SAS proof would use segment FD in Line 4, so it could be argued that the first mistake is there.

A company makes poppy lapel pins.

Answer:

<h2>The required percentage is 65.45%.</h2>

Step-by-step explanation:

The total costing is $1000 \times 1.10 = 1100$

35% were given to the charity, hence 350 were given to the charity.

There are (1000 - 350) = 650 lapel pins remaining.

60% of 650 = $\frac{60}{100} \times 650 = 390$ werre sold for 3.00 each. Hence, earning from here is $390 \times3 = 1170$ .

40% of 650 = 260 were sold at 5.00 for 2. It can also be said that $\frac{260}{2} = 130$ were sold at 5.00 each. Earning from this section is $130 \times5 = 650$
