<em><u>Answer: 10.</u></em>
<em><u /></em>
<em><u>Step-by-step explanation:</u></em>
<em><u>DIVISION. 120/12.</u></em>
<em><u>That is hard! Here's a trick.</u></em>
<em><u>12x9= 99=9=108. Or 12x6=66+6=72.</u></em>
<em><u>We will stick with 12x9, that equals 108.</u></em>
<em><u>We should add another 12 until we get to 120. </u></em>
<em><u>108+12=120. That is 10 times. The trick was...</u></em>
<em><u>dividing by 12 is hard, so lets say 12x4. I can put 4 and 4 together.</u></em>
<em><u>44 then and another 4. That is 48. So 12x4=48.</u></em>

Answer:
It is -1.602 x 10^-19 C, and the smallest unit of charge
Step-by-step explanation:
The charge on an electron is 
. The charge on electron is negative. The quantization of electric charge is :
q = ne
q is net charge
n is no of electrons
e is the electronic charge which is 
. Hence, the correct option is (b).
Answer:
The volume is 210 cm³
Step-by-step explanation:
The way to solve volume is LxWxH, so you would do 6x5x7 and you get 210.
Answer:
485.9 mm³
Step-by-step explanation:
The volume of a sphere is 4/3 π r³. So the volume of a hemisphere is half of that:
<h3>V = (2 / 3) π r³</h3>
V = 128π/3
The formula for the volume of a cylinder is V = Bh or V = πr²h .
The radius of the cylinder is 4mm and the height is 7mm
Substitute 4 for r and 7 for h in the formula V = πr²h .
<h3>V=π(4)²(7)</h3>
V = 112π
Since the figure is made up of a hemisphere and cylinder so volume will be sum of these two shapes
<h3>V = 128π/3 + 112π</h3>
= 485.9 mm³
