Answer:
30% decrease
Step-by-step explanation:
Thickness of 1 quarter = 1.75 mm
So, 1000 quarters will be = 
= 1750 mm
So, a stack of 1000 quarters will be 1750 mm high.
By finding the maximum common factor between the number of spoons, we conclude that he must put 6 teaspoons per bag.
There will be 8 bags in total.
<h3>How many teaspoons of spice should the clerk put in each bag?</h3>
We know that the store clerk has 18 teaspoons of cinnamon and 30 spoons of nutmeg.
Now, we want to put these in bags, such that each bag contains the same number of teaspoons.
Then the number of teaspoons per bag must be a common factor of 30 and 18. (the minimum number of bags is what we get when we select the maximum common factor).
Decomposing these two numbers gives:
30 = 2*3*5
18 = 2*3*3
Then the maximum common factor is 2*3 = 6
This means that we need to put 6 teaspoons per bag.
And the total number of teaspoons is 30 + 18 = 48, dividing that by 6 we get:
48/6 = 8
There will be 8 bags.

Answer:
132 
Step-by-step explanation:
Triangle formula is 1/2 bh (4x3/2) is 6 (4 triangles)=24
Base is 6x8=48
sides are 6x5=30 then multiply by 2 of the sides =60
add all together
Vcylinder-vcone=vair
vcylinder=hpir^2
vcone=(1/3)hpir^2
vcylinder=16*pi*5^2=400pi
vcone=(1/3)12*pi*4^2=64pi
vylinder-cone=400pi-64pi=336pi
volume is 336pi cubic centimeters or aprox 1055.5 cubic cm
