Assuming the population growth models continue to represent the growth of the forests, which forest will have a greater number o

Maksim231197 [3]

The given population models for the trees is given as:

$\begin{gathered} A(t)=115(1.025)^t \\ B(t)=82(1.029)^t \end{gathered}$

It is required to find which forest will have a greater number of trees after 20 years and by how many.

To do this substitute t=20 in the equations of the models:

$A(20)=115(1.025)^{20}\approx188$ $B(20)=82(1.029)^{20}\approx145$

Hence, forest A has a greater number of trees after 20 years.

Calculate the difference:

$188-145=43$

It follows that forest A has a greater number of trees than forest B by 43 trees.

After 20 years, forest A has a greater number of trees than forest B by 43 trees.

Thirty percent of Irma’s Boutique’s sales came from leggings. They sold $390 worth of leggings last week. What were the total sa

RUDIKE [14]

Answer:

The total sales of Boutique last week = $1300

Step-by-step explanation:

Given that:

Percent of sales came from leggings = 30%

Worth of leggings sold = $390

Let,

x be the total sales in the week.

30% of x = 390

$\frac{30}{100}x=390$

0.3x = 390

Dividing both sides by 0.3

$\frac{0.3x}{0.3}=\frac{390}{0.3}\\x=1300$

Hence,

The total sales of Boutique last week = $1300

List the components in the proportion relationship used to find missing value in scale drawing?

Phoenix [80]

<h2>Explanation:</h2><h2></h2>

When we have relationships between two variables and their ratios are equivalent, we call this as proportional relationship. A scale drawing is a model that has been reduced or enlarged from its original size. Suppose you have a horse that measures 1,5m high by 2m long and want to draw a reduced model by a scale factor of 1:10, then your drawing will measure:

$Height=1.5(1/10)=0.15m \\ \\ Length=2(1/10)=0.2m$

So the components are:

Measurements of the original object
Measurements of the drawing
Scale factor
