The correct answer is Choice B: 720.
To solve this, you have to use the Fundamental Counting Principal. You find the total number of options for each of the digits, then multiply them together.
For the first one, there are 10 options, then 9 options and finally 8 options.
10 x 9 x 8 = 720
Does the rate of change equal for each.
take the output difference and divide by the input distance
1st -5/10 = -1/2
2nd -1/2
3rd -5/10.= -1/2
Area of a triangle=bh/2
27= x(x-3)/2
27= (x^2-3x)/2
54= x^2-3x
x^2-3x-54=0
(x-9)(x+6)=0
x=9, x=-6.
In this case, x must equal 9 since the base cannot be a negative number.
Final answer: Height=6 m
If you are using a calculator, simply enter 16÷72×100 which will give you 22.22 as the answer.
