Answer:
Let C be the position of a person in a helicopter. A,B be two objects lying opposite to each other on either bank of a river.
Let AD=x,BD=y
In ΔACD,
⇒tan30
o
=
AD
CD
⇒
3
1
=
x
700
⇒x=130
3
⇒x=130(1.732)=1212.4
∴ the width of the river =x+y
=1212.4+130
=1342.4m
Step-by-step explanation:
Answer:
use some propoerties of exponnets
(x^m)/(x^n)=x^(m-n)
so
convert every body to scientific notation
(number less than 10 but equal to or greater than 1) times (10^x)
baby=26,000,000,000
how many decila places to move to left to make less than 10 but equal to or great than 1
10
there for it can be writtten as
2.6*10^10
how many times bigger is adult than baby
baby times x=adult
divide adult by baby with the numbers
x==
times =
1.9 times 10^3
answer is 1.9*10^3
