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:
96
Step-by-step explanation:
3*4*8=96
We know that the volume is: V = 1 gallon = 231 in³
Also : r = 3 in.
The volume of a cylinder: V = r² π h
231 = 3³ · 3.14 · h
231 = 9 · 3.14 · h
231 = 28.26 h
h = 231 : 28.26
h = 8.17 ≈ 8 in
Answer: C) 8 in.
Answer: Length of shorter side is 2.8 cm.
Explanation:
Since we have given that
Dimensions of a room are given by

On a plan, the longer side = 4 cm
As we know that the ratio of original room is equal to ratio of plan room
So,

So, length of shorter side is 2.8 cm.
