Answer:
Paul is the youngest at 17 years old. Fiona is 20 years old, Sara is 23 years old
Step-by-step explanation:
Assign variables to the ages.
S = sara's age
F = Fiona's age
P = Paul's age.
S + F + P = 60
S = 3 + F
P = F - 3
(3 + F) + F + (F - 3) = 60
3 + 3F - 3 = 60
3F = 60
F = 20
S = 23
P = 17

Answer:
1) 04.4750
Step-by-step explanation:
The most obvious reason would be that if you put in 3.58 x 1.25 into a calculator the answer u get is 4.4750.
If you want a more technical explanation though, you can say that the combined number of decimal places in the multiplicand and the multiplier is 4, so the product will also have 4 decimal places.
3.58 = two decimal places
1.24 = 2 decimal places
in total, they have 4 decimal places. for the product to have 4 decimal places too you'd count from right to left 4 places, and that's where you'd put the decimal. Hope this helps!
CD = sqrt (6^2 - 5^2)
CD = sqrt(36 - 25)
CD = sqrt(11)
CD = 3.3
