A regular pentagon is dilated by a scale factor of 73 7 3 to create a new pentagon. How does the perimeter of the new pentagon c

solmaris [256]

Answer:

The perimeter of the new pentagon is equal to $\frac{7}{3}$ times the perimeter of the original pentagon

Step-by-step explanation:

we know that

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

Let

z-------> the scale factor

x------> the perimeter of the new pentagon

y-----> the perimeter of the original pentagon

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

In this problem we have

$z=\frac{7}{3}$

substitute

$\frac{x}{y}=\frac{7}{3}$

$x=\frac{7}{3}y$

therefore

The perimeter of the new pentagon is equal to $\frac{7}{3}$ times the perimeter of the original pentagon

Jayden has $100 and saves $25 per week. Liv has $180 and spends $15 per week. How many weeks until they have the same amount of

Karolina [17]

Answer:

Both of them will have the amount of money after $2$ weeks and both of them have $\$\: 150$ .

Step-by-step explanation:

Jayden has $100 and saves $25 per week.

Liv has $180 and spends $15 per week.

Let both of them have the same amount of money after $x$ weeks.

According to the question,

$\Rightarrow 100+25x=180-15x$

$\Rightarrow 25x+15x=180-100$

$\Rightarrow 40x=80$

$\Rightarrow x=\frac{80}{40}$

$\Rightarrow x=2$

So, both of them will have the amount of money after $2$ weeks.

After $2$ weeks, Jason will have $100+25\times 2=100+50=150$ dollars.

Hence, both of them will have the amount of money after $2$ weeks and both of them have $\$\: 150$ .
