Answer:
rub the magnets with a stronger magnet then they would be more magnetized
Explanation: If you rub a magnet with lets say some metal then that metal would be magnetized so if you where to rub those 2 magnets with a stronger magnet those magnetized would be magnetized even more than they already are
Answer:
4
Step-by-step explanation:
AD=4+8=12=DE thus angle EAD= angle AED=90÷2=45
angle ACB=90-45=45 thus CB=AB=4
So this translates to:
5e + 5n = 25.95
2e + 6n = 22.38
One way to solve that is to multiply the top equation by 2, and the bottom equation by 5:
10e + 10n = 51.90
10e + 30n = 111.90
Then subtract the top from the bottom to get:
20n = 60
and divide by 20 to get
n = 3
So you know that note paper costs $3. Substituting that into the top equation you get:
5e + 5*3 = 25.95 or
5e + 15 = 25.95
Subtracting 15 from both sides you get:
5e = 10.95
Dividing by 5 you get:
e = $2.19
