Answer:

1

Step-by-step explanation:

The cone is sliced by a plane, which produces a smaller cone on top.  This cone is similar to the original cone.  Therefore:

R / H = r / h

2 / 8 = r / 4

r = 1

Order the numbers from greatest to least based on their absolute value:
Valentin [98]
<h3>Answer: |-34|, |-25|, |0.5|, |0.35|</h3>

==============================================================

Explanation:

The absolute value of a negative number is the positive version of that number

|-25| = 25

|-34| = 34

The absolute value of a positive number is that exact same number

|0.5| = 0.5

|0.35| = 0.35

Absolute value represents the distance a number is from 0 on the number line. The distance is never negative, which is why |-25| = 25 for instance.

---------------

After simplifying each absolute value, we get this list {25, 0.5, 34, 0.35}

That sorts from greatest to least to get {34, 25, 0.5, 0.35}

This means the answer is |-34|, |-25|, |0.5|, |0.35|

----------------

note: it might help to think of 0.5 as 0.50, so you can see that 0.50 is larger than 0.35

Answer:

5

8

14

Step-by-step explanation:

1. 4^{0} + 2 \times 3 - 2 = 1 + 6 - 2 = 5 (Answer)

{As we know that a^{0} = 1 for a ≠ 0}

2. 2^{2} + 10 - 3 \times 2 = 4 + 10 - 6 = 8 (Answer)

{We know, a^{2} = a \times a}

3. 9 + 3^{2} - 1 \times 4 = 9 + 9 - 4 = 14 (Answer)

Note: When there is no brackets, we perform the operation of '×' and '÷' first and then we perform the operation of '+' or '-'
