Answer is B because the red has 2 columns and 7 rows that is how you get 2/7 And the blue has 3 rows and 5 columns making 3/5
If you multiply these together you get the doubled colored (red/blue over the total of squares)
6/35
The other way which most likely I think you should choose this way is D why?? Because there are out of the red are 3 out of 7 rows that are combined with blue and 2 out of 5 of the blue column are combined with red This makes the 3/7×2/5 = with the 6/35 (combined colors/total)

Answer:

2000= 600+2/5x

Step-by-step explanation:

length = X Ft

(2/5)x+600=2000

multiple both sides by 5/2:

x + 1500= 5000

x= 3500 ft

Answer:

Circumference: 12.56 yd
Area: 12.56 yd²

Step-by-step explanation:

The circumference is given by ...

C = πd

C = (3.14)(4 yd) = 12.56 yd

The area is given in terms of diameter by ...

A = (π/4)d²

A = (3.14/4)(4 yd)² = 12.56 yd²

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:

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

Please answer this in two minutes

ryzh [129]

Answer:

<h2>X = 59°</h2>

Step-by-step explanation:

To find Angle X we use sine

sin∅ = opposite/ hypotenuse

From the question

WY is the opposite

WX is the hypotenuse

So we have

sin X = WY/ WX

sin X = 6/7

X = sin-¹ 6/7

X = 58.99

X = 59° to the nearest tenth

Hope this helps you
