To multiply these numbers, the first step is to writhe "-8" as an improper fraction, to do so, divide it by 1
Next is to solve the multiplication, to do so, first multiply the first two terms of the multiplication:
The multiplication is between two negative numbers, when you multiply two negative numbers, the minus signs cancel each other and turn into a positive value, this is called "double-negative"
Next multiply the result by the third fraction -2/5
This time you are multiplying a positive and a negative number, so the result of the calculation will be negative
Final step is to simplify the result, both 144 and 15 are divisible by 3, so divide the numerator and denominator by 3 to simplify the result to the simplest form:
For this case you can write a weighted average expression to find the average number of tickets sold per child.
We have then that an expression that can represent this average is the following:
average = (((tickets1) * (class1)) + ((tickets2) * (class2)) + ((tickets3) * (class3))) / ((class1) + (class2) + (class3))
answer
an expression for the average number of tickets sold per school child is
average = (((tickets1) * (class1)) + ((tickets2) * (class2)) + ((tickets3) * (class3))) / ((class1) + (class2) + (class3))
The ratio of circumference/diameter for all circles is π. And the ratio of force/mass for all freely-falling bodies will be g.
<h3>What is the circumference of a circle?</h3>
Let d be the diameter of the circle. The circumference of the circle will be
C = πd units
The ratio of circumference to diameter for all circles is pie.
C/D = πd / d
C/D = π
Then the ratio of force to mass for all freely-falling bodies will be
The force acting on a free-falling body of mass (m) is mg. Then we have
Force/Mass = mg / m
Force/Mass = g
Where g is the acceleration due to gravity.
