No 2:4 is equal to 1:2 but you can’t simplify 3:5

Answer:

No, they are not.

Step-by-step explanation:

A ratio can be written as a fraction. So 3:5 is the same as 3/5 and 2:4 is the same as 2/4.

3/5 = 2/4

0.6 = 0.5 INCORRECT

As you can see, the both don't equal the same numbers, so they aren't equivalent.

Can y’all help find the surface area please and thank you

solong [7]

To find the area of a complex shape:

⇒ must cut the whole shape into a simpler shape

square with side lengths of 4 in
2 triangles with a base of 4 in. and a height of 8 in.
2 triangles with a base of 4 in. and a height of 10 in.

Let's calculate:

Area of 2 triangles with a base of 4 in. and a height of 8 in.

$Area = \frac{1}{2}*4*8 + \frac{1}{2}*4*8=16+16=32\\$

2 triangles with a base of 4 in. and a height of 10 in.

$Area = \frac{1}{2}*4*10 + \frac{1}{2}*4*10=20+20=40$

square with side lengths of 4 in

$Area = 4 * 4=16$

Total Area: 32 + 40 + 16 = 88 in²

Answer: 88 in²

Hope that helps!
