<h2>the answer i thinkk is 2/20 because since there ae 20 children, then the brother and sister each have a 1% chance, hope this helped!</h2>
Answer:
Step-by-step explanation:
If angle C is the right angle, then side c is the hypotenuse.
Use Pythagoras' Theorem 
to find the length of side a:
Given:
<u>Tan Trig Ratio</u>
where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
Given:
- = A
- O = side opposite angle A = a = 9
- A = side adjacent angle A = b = 2√22
Answer:
First of all the rate of change is -2, so the answer would be y = x - 2
Answer:
W = mgh
W = 226290 x 9.8 x 9
W = 19958778Joules
W= 19.958778MegaJoules
Step-by-step explanation:
Work to full the tank is
W = mgh.
m is the mass of the water.
But density = mass/volume, where volume is the volume of the complete the remaining half full of water to fill the cylindrical tank.
mass = density x volume.
Volume of cylinder = πr2h
Volume to fill the cylinder = (πr2h)/2.(half of total volume)
Volume = (22x4x4x9)/(7x2). Height used is 18/2 = 9m
Volume = 226.29m3.
Mass = density x volume= 1000 x 226.29 = 226290kg
Therefore, the work is
W = mgh
W = 226290 x 9.8 x 9
W = 19958778Joule = 19.958778MegaJoules
Your answer would be A:x=3
