Answer:
60 mins or 1 hour
Step-by-step explanation:
14 x 2 : 28 - 25 plus 25 is 50 min
38- 28 is 10
50 plus 10 is 60 min Or 1 hour
You need to replace x with 5 so it will be…
[3(5) + 4] - (2 - 5)
(15 + 4) - (-3)
19 + 3
22
First multiply both 4 and 18:
4*18=72
According to formula:
G(a1.a2) = sqrt(a1.a2)
G(a1.a2.a3) = 1/3 root of (a1.a2.a3)
As there are only 2 numbers whose geometric mean to be calculated, we take square root of multiplication of two numbers.
Sqrt(72) = 8.4852
# of boys : # of girls
This can be written as
6:15
6 to 15, or
6/15
