Find the area of the figure.EXPlAIN THE STEPS!!!!

hichkok12 [17]

Answer:

30.56 yd²

Step-by-step explanation:

To determine the area of the composite shape, we need to:

Divide the shape into two smaller "known" shapes (Refer to image).
Determine the area of those "known" shapes.
Add the area of the known shapes to obtain the area of the figure.

Determining the area of shape 1 (Rectangle 1):

⇒ Area of rectangle = Lenght × Breadth

⇒ = 2.1 × 4.8

⇒ = 10.08 yd²

Determining the area of shape 2 (Rectangle 2):

⇒ Area of rectangle = Lenght × Breadth

⇒ = 6.4 × 3.2

⇒ = 20.48 yd²

Determining the area of the figure:

⇒ Area of figure = Area of rectangle 1 + Area of rectangle 2

⇒ = 10.08 + 20.48

⇒ = 30.56 yd²

19. The population of Jose's town in 1995 was 2400 and the population in 2000 was

Fantom [35]

The linear equation in slope intercept form for population of Jose's town is y = 320x + 2400.

Solution:

Given, the population of Jose's town in 1995 was 2400 and the population in 2000 was 4000,

Let x represent the number of years since 1995.

We have to write a linear equation, in slope- intercept form, that represents this data.

Now, let the change in population per year be p.

Then, population in a year = population change per year $\times$ number of years + population in 1995.

⇒population in a year = p $\times$ x + population in 1995

⇒ population in a year = p $\times$ x + 2400

Here we have an case that, population in 2000 is 4000

Then, number of years since 1995 = 5

So, 4000 = p $\times$ 5 + 2400 ⇒ 5p = 4000 – 2400 ⇒ 5p = 1600 ⇒ p = 320

Then, our equation will be population in a year = 320x + 2400

Considering the population in a year as y ⇒ y = 320x + 2400.

Hence, the linear equation in slope intercept form is y = 320x + 2400.

How many solutions doe

musickatia [10]

Answer:

Given equation have two solutions.

x = $-\frac{5}{2} and -\frac{8}{3}$

Right option is (D)

Step-by-step explanation:

We have given,

$6x^{2} +40=-31x$

we can rewrite this equation in the form given as:

6x² + 40 + 31x = 0

or 6x² + 31x + 40 = 0

On solving this quadratic equation, we get :

x = $-\frac{5}{2} and -\frac{8}{3}$

That means, given equation have two solutions.

Right option is (D)
