Answer:

646.04 cm³

Step-by-step explanation:

<u>Cube volume formula:</u>

V=l*w*h

V=8*8*8

V=512

<u>Hemisphere volume formula:</u>

V=(4/3πr³)1/2

V=(4/3π4³)1/2

V=128/3

<u>Add both together</u>

128/3 + 512 ≈ 646.04cm³

Drag each expression to show whether it is equivalent to 54x + 18, 18(3x – 1), or (6 • 9x) + (6 • 1).
yulyashka [42]

Answer:

See the attachment.

Step-by-step explanation:

In each case, the variable term is 54x, so what makes it be one answer or another is the value of the constant term. The various expressions have one of these constants: +18, -18, or +6.

The two expressions with minus signs go in the "-18" bin.

The two expressions with either +6 or 3(__+2) will go into the "+6" bin.

The remaining two expressions go into the "+18" bin.

What is (20-(-16))=20+16=36
wel

Answer:

Yes.

(20-(-16)) = 20 + 16

20 + 16 = 36 thus

(20-(-16)) = 36

Step-by-step explanation:

With your equation, I'm pretty sure you are trying to determine whether or not this equation is true. Let's start with the first part.

(20-(-16))

Let's break it down.

20 - -16

Whenever a number is like that, it becomes a positive. (I don't really remember what its called, but it flips in negativity)

20 + 16

20 + 16 = 36.

36 = (20-(-16))

Select all of the following expressions that are equivalent to 0.25.. . 1. (0.5)2. 2. (-0.2) + (-0.05). 3. |-3 + 2.75|. 4. -(-0.
shepuryov [24]
The solutions for the following expressions are:
1. 0.5*2 = 1
2. -0.2+-0.05= -0.25
3. absolute value of (-3+2.75) = 0.25
4. -(-0.25) = 0.25
5. 2x-1.75x = 0.25x

The expression equivalent to 0.25 is numbers 3 and 4.
