30*47382 is the correct answer
From the diagram provided, the two lines that are left and right of each other are parallel and are cut by a transversal. That means,

If angle 9 equals 130, then angle 8 equals,

If angle 8 equals angle 4, then angle 4 equals 50 degrees
Answer:
11 positive integers can be expressed.
Step-by-step explanation:
Consider the provided information.
The number of possible prime numbers are 5,7,11,and 13.
There are 4 possible prime numbers.
How many positive integers can be expressed as a product of two or more of the prime numbers, that means there can be product of two numbers, three number or four numbers.
The formula to calculate combinations is: 
The number of ways are:




Hence, 11 positive integers can be expressed.
Well, one example would be how much space is in a cardboard box, to ship something to a friend or relative.
We know the three measurements:
L = Length, W = Width, and H = Height.
And the formula for a volume of a cube is:
V = L*W*H
So say that:
L = 6 , W = 10 Feet, and H = 3 Feet.
By using the formula above we get the equation: V = 6*10*3
And that equals: 180 Feet.
So the volume of the box, or the space you have to send something is 180 square feet.
