Answer:

c. Climax

Step-by-step explanation:

Climax community is an ecological community in it final stage of succession, in which the species that makes up the community are relatively stable unless a rare earth disaster like earthquakes, fire etc destabilize the system.

The climax community has reached the stable stage. The community is well defined and extensive . This stability is usually actualized when more complex organisms replace more simple organism. Succession in this kind of community has occurred severally until it reaches it reaches the climax stage. Most climax community takes hundreds and millions of years to reach stability. This stability is achieved through succession : a process whereby natural communities is replaced by another. For example grass may invade an ordinary flat sandy surface then the grass will provide humus for other more complex species to grow like oaks and beeches tree before it reaches a stable community.

} A rectangle has an area of 25 square feet. A similar rectangle has an area of 200 square feet. What is ratio of the areas of t

ValentinkaMS [17]

Answer:

The ratio of smaller rectangle to larger is 1 : 8.

Step-by-step explanation:

Given that:

Area of smaller rectangle = 25 square feet

Area of larger rectangle = 200 square feet

Ratio of areas of these similar rectangles;

Smaller rectangle : Larger rectangle

25 : 200

1 : 8

Hence,

The ratio of smaller rectangle to larger is 1 : 8.

PLEASE HELP!! WILL MARK BRAINLIEST!!

sladkih [1.3K]

Answer:

if u have any doubts feel free to ask :)

Step-by-step explanation:

Sum of ratio : 9 + 7 + 4 = 20

Adele share :

$\frac{9}{20} \times 680 = 9 \times 34 = \$ 306$

Barbara share :

$\frac{7}{20} \times 680 = 7 \times 34 =\$ 238$

Collette share :

$\frac{4}{20} \times 680 = 4 \times 34 = \$ 136$

$ €

1.125 1

306 x

$\frac{1.125}{306} = \frac{1}{x}$ [cross multiply]

$x =\frac{ 306} {1.125}$

x = €272

Adele receives = €272

Apple Cost

1 kg 2.69

5 kg y

y = 2.69 x 5 = $13.45

Cost of 5kg of apples = $13.45

Cost of 3 kg bananas = 17.56 - 13.45 = $4.11

Banana Cost

3kg 4.11

1 kg z

$z = \frac{4.11}{3}$

z = $1.37

Cost per kilogram of banana = $1.37

e) Collette share = $136

Half of it on clothes = (1/2) x 136 = $68

(1/5) of her share on books = (1/5) x 136 = 27.20

Balance amount with her = 136 - 27.20 - 68 = $ 40.80

Find the distance between each pair of points.<br> 3) (6, -2), (8, -3)<br> 4) (7,-8), (-8, 2)

castortr0y [4]

Answer:

3) $\sqrt{5}$

4) $5\sqrt{13}$

Step-by-step explanation:

distance between two points:

$d = \sqrt{(x_{2}-x_{1})^{2}+ (y_{2}-y_{1})^{2}}$

we have:

3) (6, -2), (8, -3)

$x_{1} = 6$

$y_{1} =-2$

$x_{2} = 8$

$y_{2} =-3$

so we have:

$d =\sqrt{(8-6)^{2}+ (-3-(-2))^{2}}\\\\d =\sqrt{(2)^{2}+ (-1)^{2}}\\\\d = \sqrt{4+ 1}\\\\d=\sqrt{5}$

4) (7,-8), (-8, 2)

$x_{1} = 7$

$y_{1} =-8$

$x_{2} =-8$

$y_{2} =2$

$d =\sqrt{(-8-7)^{2}+ (2-(-8))^{2}}\\\\d =\sqrt{(-15)^{2}+ (10)^{2}}\\\\d = \sqrt{225+ 100}\\\\d=\sqrt{325}\\\\d=5\sqrt{13}$

What is y? i am having trouble figuring out what y is

Andre45 [30]

Answer:

$\sf \boxed{\bf y =5\sqrt{22}}$

Step-by-step explanation:

<h3>45° - 45° - 90° triangle:</h3>

The ratio of sides of 45 - 45 - 90 triangle is a : a : a√2.

a is the side opposite to 45°.

From the figure, a = 5√11

The side opposite to 90° is a√2.

y = a√2

$\sf = 5\sqrt{11} * \sqrt{2}\\\\ = 5*\sqrt{11*2}\\\\ = 5\sqrt{22}$
