Answer:
Find the circumference of a circle with radius, r = 3.5m.
2x3.5xpi = 7pi is answer
Again set a proportion
x/4=35.25/1
=x=4(35.25)
x=141
Therefore the boat traveled 141 kilometres.
The answer is C.
Answer:
Angle 8 = Angle 4
Step-by-step explanation:
Answer:
x = -1
Step-by-step explanation:
AB + BC = AC = 28
the way from A to C goes through B.
so, the total way of A to C is the sum of the way from A to B and then from B to C.
=>
(5x + 10) + (2x + 25) = 28
7x + 35 = 28
7x = -7
x = -1
