Answer:

2.23

Step-by-step explanation:

The reason why this is your answer is that this number is between 2 2/10 and 2 3/10. That means that turned into decimals, this number will be somewhere between 2.2-2.3

Now, we can see that this is 3 units away from 2 2/10 on the number line, which tells us that the decimal is 2.23

So hence, your answer is 2.23

What is the volume of the rectangular prism?

Answers

Answer:

I think the answer will be 32,768 cubic units..

Step-by-step explanation:

The volume formula is length times width times height and you say that the area of the shaded face is 96 square cm is better we divide

96/3 =32

So, we took the colume formula like this:

V= L x W x H

= 32 x 32 x 32

= 1,024 x 32

= 32,768 cubic units

{An angle measures 150° less than the measure of its supplementary angle. What is the measure of each angle?}

Answers

Answer:

165° & 15°

Step-by-step explanation:

Let the first angle be 'a'

second angle be (a-150°)

a+(a-150°) = 180°

2a=180°+150°

2a=330°

a=330/2

a=165°

first angle is 165°

second angle is 165-150=15°
