Arlecino [84]

Answer:

Ratio of perimeters = 7 : 9

Step-by-step explanation:

Each side of the smaller triangle is 7 by 9 times the length of the corresponding side of the large triangle.

$\text{Now, Since each side of the triangle is scaled by a factor of }\frac{7}{9}\\\text{So, sum of the lengths of the three sides will also be scaled by a factor of }\frac{7}{9}$

$\text{Therefore, the ratio of the perimeters of the two triangles }\\\text{will be the same as the scale factor : }\frac{7}{9}$

il63 [147K]

Answer:

Step-by-step explanation:

Alright, lets get started.

In the morning Cynthia completed the work = $\frac{2}{3}$

During her lunch break, she completed = $\frac{1}{8}$

So, she completed total of her work : $\frac{2}{3}+\frac{1}{8}$

So, we need to add these two fractions.

First making common denominator , so

$\frac{16}{24}+\frac{3}{24}$

So, adding = $\frac{19}{24}$

It means she had finished $\frac{19}{24}$ fraction of het to do list. : Answer
