Answer:
The total number of pencils is 6
Step-by-step explanation:
According to the given scenario, the computation of the total number of pencils is as follows:
There are 18 students
And let us assume there is m mechanical pencils that put in each bag
also he put twice of the regular pencil
So if he put the 3 mechanical pencil
So, the total number of pencils is
= 3 × 2
= 6
As it twice of the regular pencil
hence, the total number of pencils is 6
Answer:
0.23$
Step-by-step explanation:
16 ounce box of cereal is priced at =3.68$
∴1 ounce box of cereal is priced at=(3.68/16)$
=0.23$
Addition, I would use the principles of addition.
Answer:
Step-by-step explanation:
To isolate <em>a</em>, we add -3.75 to both sides.
<em>a</em>-(-3.75)=6.11
<em>a</em>-(-3.75)<u><em>+(-3.75)</em></u>=6.11<u><em>+(-3.75)</em></u>
<em>a</em>=6.11<em><u>+(-3.75)</u></em> Simplifying, we get:
<em>a</em>=2.36
(I got this from khan)
Given that the volume of a cell is 50 cubic micrometers. It says to find the number of cells present in 1 cubic centimeter.
So we need to first convert the units of volume of a cell, then we can find the total number of cells in 1 cubic centimeter.
We know 1 meter = 100 centimeters = 1000000 micrometers
So 1 centimeter = 10000 micrometers
Taking Cubic powers on both sides :-
1 cubic centimeters = 10¹² cubic micrometers
1 cubic micrometers = 10⁻¹² cubic centimeters
50 cubic micrometers = 50 × 10⁻¹² = 5 × 10⁻¹¹ cubic centimeters
So volume of one cell = 5 × 10⁻¹¹ cubic centimeters
Number of cells = 
= 2 × 10¹⁰ cells.
So, total number of cells = 2 × 10¹⁰ cells.
