Split the shape in 3 rectangles
4x2=8x2= 16 ( the bottom and top rectangle)
6x2= 12 (middle rectangle)
16+12=28
There are two sides in a coin so the chance of getting tails is 1/2, which would be 0.5.
I'm not sure tho.
Answer:
1/400
Step-by-step explanation:
i put it in the calculator and got 1/400
It is given that z varies directly with x and inversely with the square of y so it follows:

It is also given that z=18 when x=6 and y=2 so it follows:

So the equation of variation becomes:

Therefore the value of z when x=7 and y=7 is given by:

Hence the value of z is 12/7 or 1.7143.
Answer:
X= -6
Step-by-step explanation:
x-4=2x+2
