Answer:
5.104 X 10^2
Step-by-step explanation:
For number five it literally answers its own question in exact words, there are 25.
Simple interest formula:
Total = start value x (1 + rate x time)
Total = 600 x (1 + 0.12 x 6)
Total = $643.20
answer: B. $643.20
32^2 + x^2 = 38^2
1024 + x^2 = 1444
-1024 -1024
x^2= 420
x=20.493901532
Answer: 13/20
Step-by-step explanation:
Recall that 60 minutes = 1 hour
So, 39 minutes = Z hour (Let the unknown hour be Z)
Then to get the value of Z,cross multiply
Z x 60 = 39 x 1
60Z = 39
Divide both sides by Z
60Z/60 = 39/60
Z = 39/60
Let 3 divide through 39 and 60
So, Z = 13/20
Thus, 13/20 of an hour is 39 minutes
