Answer:
The least number of stamps required is 
Step-by-step explanation:
Let the number of 
cent stamps be 
and 
cent stamps be 
We have
The minimum number is obtained when more cent stamps are used
Here cannot be greater than 
since 
Substitute 
Not possible since is not a fraction
Substitute 
Not possible since is not a fraction
Substitute 
Possible
Hence minimum number of stamps is
Answer:
SA = 105 in^2
Step-by-step explanation:
To find surface area, find the area of all the shapes and add it all together. This shape has 4 triangle faces. They are all the same. So we can find one of them and times by 4.
Area of a triangle:
A = 1/2b•h
= 1/2• 5 • 8
= 1/2 • 40
= 20
One triangle has area 20, so times by 4 (bc four triangles)
4•20
= 80
Area of square 5•5
= 25
Add the areas:
80 + 25
= 105 sq in
Answer:
Simplified answer = 11.1 - 10y = 0
y = 1.11
Step-by-step explanation:
6 - 2y + (-8y) + 5.1 = 0
6 + 5.1 -2y -8y = 0
Add like terms
11.1 - 10y = 0
(This is simplified, but if you want to solve for y, continue)
11.1 - 10y = 0
÷10 ÷10
1.11 - y = 0
y = 1.11 because 1.11 - 1.11 is 0
I Hope That This Helps!
