5 x 5 = 25
25 x 6 = 150

7049 needs to be rounded to the nearest thousand = 7000
1859 needs to be rounded to the nearest hundred = 1900
7000+1900= 8900
Because the account is compounded continuously, Euler number is required
e = 2.7182818
Givn : OK = 3, OJ = 30, KN = 1, JM = 3
ON=OK+KN=3+1=4
OM=OJ+JM=30+10=40
In triangles OKJ & ONM,
OKOJ=330=110
ONOM=440=110
Angle O is common in both the triangles.
Two sides are in same proportion and the included angle is common (SAS) . Hence both the triangles are similar.
That means KJNM=110 or the two sides are parallel.
Hence ˆK=ˆN,ˆJ=ˆM corresponding angles.
When the signs of the two numbers are the same, the answer will be positive. When the signs of the two numbers are different, the answer will be negative.
