Answer:

The perimeter of △EFG is $62\ units$

Step-by-step explanation:

we know that

In the figure the smaller triangle and triangle EFG are similar by AA Similarity Theorem

Remember that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

Find the length side EG

$\frac{9}{EF}=\frac{14}{EG}$

substitute the given values

$\frac{9}{9+9}=\frac{14}{EG}$

$\frac{9}{18}=\frac{14}{EG}$

$\frac{1}{2}=\frac{14}{EG}$

$EG=14(2)=28\ units$

Find the perimeter of △EFG

$P=EF+EG+FG$

substitute

$P=2(9)+28+2(8)$

$P=62\ units$

Yuki888 [10]

$1;\ \frac{1}{32};\ \frac{1}{243};\ \frac{1}{1024};\ \frac{1}{3125}\\\\1=\frac{1}{1^5}\\\\\frac{1}{32}=\frac{1}{2^5}\\\\\frac{1}{243}=\frac{1}{3^5}\\\\\frac{1}{1024}=\frac{1}{4^5}\\\\\frac{1}{3125}=\frac{1}{5^5}\\\vdots\\\\a_n=\frac{1}{n^5}\ where\ n\in\mathbb{N^+}$

Shannon feeds her cat twice a day. In the morning, she feeds her cat one can of cat food. In the evening, she feeds her cat one

saul85 [17]

Each can of cat food holds 4 ounces

Step-by-step explanation:

We shall assign the ounces of one can as; x

Since the cat is fed 1 can in the morning and 1 and ½ cans in the evening, then the cat eats;

x + ³/2 x ounces per day

This is also equal to 10 ounces

x + ³/2 x = 10

⁵/2 x = 10

x = 10 * ²/5

x = 4

= 4 ounces
