Answer:
where is the picture???
what are the given lengths?
(x + y = 29)
(y = 29 - x)
(5x + 2(29 - x) = 100)
(5x + 58 - 2x = 100)
(3x = 42)
(x = 14)
(y = 15)

Given:
Height of right triangle = 9 mi
Hypotenuse = 17.5 mi
Base of right triangle = Distance across lake
To find:
The distance across the lake.
Solution:
Using Pythagoras theorem:
In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.


Subtract 81 from both sides.


Taking square root on both sides.
⇒ base = 15
The distance across the lake 15 mi.
Yo sup??
To find P(A and C) we have to simply multiply the probabilities of getting an A with that of getting a C
P(A)=0.6
P(C|A)=0.3
P(A and C)=0.6*0.3
=0.18
Hope this helps.
