Answer: 8 and 80
Step-by-step explanation:
8 * 5 = 40
8 * 10 = 80
8 must be the hcf of two separate numbers. So, one of them must be 8, and the other must be greater than 8.
Multiples of 8:
8
16
24
32
40
48
56
64
72
80
The numbers on that list that multiply evenly to 80:
8, 16, 40, 80
16 is the lowest common multiple of 16 and 8
40 is the lowest common multiple of 40 and 8
80 is the lowest common multiple of 80 and 8
So the two numbers are 8 and 80; the highest common factor (HCF) is indeed 8.

Answer:
After 10 years
Rick will have $1,480.24
Sally will have $1,500
Step-by-step explanation:
Data provided in the question:
Principle amount = $1,000
Now,
For Rick
Interest rate by bank, r = 4% = 0.04
Time period, n = 10 years
Now,
Final amount after 10 years with Rick using the compounding formula
Final amount = Principle × (1 + r)ⁿ
= $1,000 × (1 + 0.04 )¹⁰
= $1,480.24
For Sally
Amount paid each year = $50
Therefore,
Total amount paid in 10 years = $50 × 10
= $500
Thus,
Final amount Sally will have after 10 years
= $1,000 + Total amount paid in 10 years
= $1,000 + $500
= $1,500
Hence,
After 10 years
Rick will have $1,480.24
Sally will have $1,500
Answer:
8421
Step-by-step explanation:
8050 < abcd < 8500
We must have a = 8, so the number is 8bcd.
The value of a is 20 times the value of b, or a= 2b.
a = 8, so b = 4.
The value of b is 20 times the value of c, or b = 2c.
b = 4, so c = 2.
The value of c is 20 times the value of d, or c = 2d.
c = 2, so d = 1.
The secret number is 8421.
