Given that the two pentagons are similar figures, the area of the pool = 675 sq. m..

<h3>What is the Area of Similar Figures?</h3>

If two figures are similar to each other, then, the ratio of the square of their corresponding sides equals the ratio of their areas.

We are given that the pool and the park are similar to each other. The diagram given is missing, however, here's how to find the area of the pool:

If x is a side of the pool and y is the corresponding side length of the park, therefore:

area of pool/area of park = x²/y².

Plug in the values given, cross multiply and find the area of the pool.

For example, if 3 is a side of the pool = x

6 is corresponding side of the park = y

Area of park = 2,700 sq. m

Thus:

Area of pool/2,700 = 3²/6²

Area of pool/2,700 = 9/36

Area of pool = (9 × 2,700)/36

Area of pool = 675 sq. m.

12 less the product of an unknown number and three equals -9.
chubhunter [2.5K]
In standard form its written 
3x-12=-9
if you need help solving then here you go as well
3x-12=-9
add 12 to both sides
3x=3
divide both sides by 3 
x=1

Find the value of x. If necessary, round your answer to the nearest tenth. The figure is not drawn to scale. (1 point) 9.7 9.2 9
Vilka [71]
X= 9.2

From the figure, the chord (12) is drawn with a line (from the center of the circle) perpendicular to it. It can be said that the chord 12 is bisected by the 7 long line from the center which gives us with 6 each of the two parts of the chord. Since they are forming (the 6 and 7) a right angled triangle, we can then use Pythagorean theorem to find X, which can be seen as the radius at the same time hypotenuse of the right angled triangle.

What is the volume of the following triangular prism?
Greeley [361]

Answer:

Option C. 42\ yd^{3}

Step-by-step explanation:

we know that

The volume of the triangular prism is equal to

V=BH

where

B is the area of the triangular base

H is the height of the prism

Convert 9 ft to yd

Remember that

1 ft=1/3 yd

9 ft=9*(1/3)=3 yd

<em>Find the area of the base B</em>

B=\frac{1}{2}(3)(4)=6\ yd^{2}

we have

H=7\ yd

substitute the values in the formula

V=BH

V=(6)(7)=42\ yd^{3}
