Answer:

The area of the circle is 153.94m²

Step-by-step explanation:

radius = half of diameter

d = diameter

r = 14m / 2 = 7m

To solve this problem we need to use the area formula of a circle:

a = area

r = radius = 7m

π = pi

a = π * r²

we replace with the known values

a = π * (7m)²

a = π * 49m²

a = 153.93804 m²

Round to the nearest hundredth

a = 153.93804m² = 153.94m²

The area of the circle is 153.94m²

if a town with a population of 500 doubles in size ever 9 years, what will the population be 36 years from now?

s344n2d4d5 [400]

The population of the town in 36 years would be 8000.

<h3>What would be the population of the town in 36 years?</h3>

The formula that can be used to determine the town's population is:
FV = P (1 + r)^n

Where:

FV = Future value
P = Present value
R = rate of growth = 100%
N = number of years = 36/9 = 4

500 x 2^4 = 8000

Answer:

Part A: What is the rate of change and initial value of the function represented by the graph, and what do they represent in this scenario?

First, calculate the rate of change (Slope, once it is a linear function):

I will take the points: $(0, 100)$ and $(1, 80)$

$m=\frac{\Delta y}{\Delta x}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}= \frac{100-80}{0-1}=-20$

Let's understand the graph!

This linear graph is about songs being downloaded in a period of 5 weeks.

In the beginning, we have 100 songs to be downloaded. As the weeks past, the number of songs remaining decreases, that's why the graph's slope is negative. In week 5, all songs were downloaded.

The initial value (100) represents the number of songs.

Part B: Write an equation in slope-intercept form to model the relationship between x and y.

The Slope-intercept form of linear equations is $y=mx+b$

where, m is the slope and b is the y-intercept.

In this case, we have

$y=-20x+100$

se tiene que embaldosar el patio interior de un edificio con baldosas cuadradas de 30 cm de lado. El patio es rectangular y sus

shepuryov [24]

Answer:

40,000 baldosas

Step-by-step explanation:

Lo primero que debemos hacer aquí es calcular el área del patio rectangular.

El mejor enfoque para esto es convertir primero sus medidas a centímetros

Matemáticamente, 100 cm = 1 m, entonces 10 m se convierten en 1000 cm y 12 m se convierten en 1200 m.

El área de un rectángulo es L * B y, por lo tanto, tenemos 1200 * 1000 = 1,200,000 cm ^ 2

Ahora, para saber la cantidad de azulejos que tendrá el patio, necesitaremos dividir el área del patio por el área de los azulejos

Matemáticamente, eso sería 1,200,000 / 30 = 40,000 fichas

Find the measure of unlabeled angle in the quadrilateral

Tpy6a [65]

Answer:

x=140

Step-by-step explanation:

A quadralterial interior angles sum up to 360. We are given three angles and need to find the missing angle.

Let x, represent the missing angle.

$60 + 55 + 105 + x = 360$

$220 + x = 360$

$x = 140$
