Answer:

Option 2nd is correct

She did not divide 30 by 5.

Step-by-step explanation:

As per the statement:

Mona solved an equation incorrectly, as shown below:

Step 1: 5x = 30

Step 2: x = 30 − 5

Step 3: x = 25

Step 2 is incorrect as she did not divide 30 by 5.

Correct steps for the equation are:

Step 1.

5x = 30

Step 2.

x = \frac{30}{5}

Step 3.

x = 6

Therefore, the statement which explains that Step 2 is incorrect in Mona's solution is, She did not divide 30 by 5.

Mona subtracted 5 where she should have divided 5. If the equasion was. x+5=30 then she would have subtracted 5.

If a height of a cone is doubled then keeping the same radius how much time the volume will increase
vaieri [72.5K]

If you double the height ;
New volume = pi * r^2 * 2h/3

So, new volume will be twice as much.
