Answer:

Step 1: Flip the equation.

−x−2=y

Step 2: Add 2 to both sides.

−x−2+2=y+2

−x=y+2

Step 3: Divide both sides by -1.

−x

−1

y+2

−1

x=−y−2

If x and y vary directly, and x=10 when y=3, what will be the value of x when y=9?

Thepotemich [5.8K]

As x and y vary directly then x∝y i.e. x=ky, where k is a constant.

When x=24, y=8 i.e. 24=k×8 and therefore

k=248=3

and relation between x and y is hence x=3y

and when y=9, x=3×9=27.

I hope this is what you're looking for.

What is the approximate area of the regular pentagon?

Anastasy [175]

Area of the pentagon: 342 cm2

Step-by-step explanation:

The figure of the pentagon is missing: find it in attachment.

The area of the pentagon can be seen as the area of 5 equal triangles, each of them having a base equal to the length of the side of the pentagon,

L = 14.1 cm

and the height of each triangle can be found by using Pythagorean's theorem:

$h=\sqrt{12^2-(\frac{L}{2})^2}=\sqrt{12^2-(\frac{14.1}{2})^2}=9.7 cm$

The area of each of the 5 triangles is

$A'=\frac{1}{2}Lh$

Therefore, the area of the pentagon is 5 times this area:

$A=5A'=\frac{5}{2}Lh=\frac{5}{2}(14.1)(9.7)=342 cm^2$

Someone help I don't know what the diameter or radius is

Elenna [48]

<h3>Answer:</h3>

52.38 inch² & 261.90 inch²

<h3>Step-by-step explanation:</h3>

Here we need to find the area of the sector . So according to formula we know the area of sector as ,

$\boxed {\sf Area_{(sector)}= \dfrac{\theta}{360}\times \pi r^2 }$

Here we can see that the central angle subtended by the arc is 60° and the radius of the circle is 10 inches . So the required area would be ,

=> Area = ∅/ 360° × π r²

=> Area = 60°/360° × 22/7 × (10in.)²

=> Area = 1/6 * 22/7 * 100 in²

=> Area = 52 .380 in²

<h3>★ Hence the area of the red sector is 52.38 inch².</h3>

_________________________________

Now let's find out the area of blue sector .The angle subtended by the arc will be (360-60)°=300° .

=> Area = 300/360 × 22/7 × 100 in²

=> Area = 261. 90 in²

<h3>★ Hence the area of blue sector is 261.90 inch².</h3>

$\boxed{\red{\sf Area _{(red \ sector )} = 52.38 in^2 }}$

$\boxed{\blue{\sf Area _{(blue \ sector )} = 261.90 in^2 }}$
