1 quarter = 25 cents.
1 dime = 10 cents.
3 quarters = 3*25 = 75 cents.
10 cents = 1 dime.
75 cents = 75 / 10 dimes
= 7.5 dimes.
Therefore 3 quarters equal 7.5 dimes.
In the number 54, 625 from left to right:
5 represents 5,
2 represents 20
6 represents 600
4 represents 4000
5 represents 50,000
so
<span>
54,625=50,000+4,000+600+20+5=5*10,000+4*1000+6*100+2*10+5
another way we can write this number is </span>

Answer:
i) 5*10,000+4*1000+6*100+2*10+5
ii)

2 ways, which are essentially the same thing.
Answer:
B.16.50
Step-by-step explanation:
2 (p - 4)=25
2p - 8 = 25
2p = 25 + 8
2p = 33
dividing the equation by 2
p = 16.50
Answer:

Step-by-step explanation:
Using the De Moivre's Theorem, let us work out for the fourth roots of 81(cos 320° + i sin 320° ).
zⁿ = rⁿ (cos nθ + i sin nθ)
z⁴ = 81(cos 320° + i sin 320° )
z = ∜[81(cos 320° + i sin 320° )]
= ∜[3^4 (cos 4*80° + i sin 4*80°)]
= 3(cos 80° + i sin 80°)
