$30,000 divided by 100 = 300 , 300 multipled by 4 = 1200 , thats how to find what 4% would be
Since, the polygon is a trapezoid made up of a rectangle and a right triangle. Therefore, according to the question, the figure of the polygon is attached.
Since, perimeter is the total length of the outer boundary of the figure. Therefore,
Perimeter of the polygon is


Area of the polygon = Area of Rectangle + Area of Triangle

So with this equation, since the volume of the cylinder is 96 pi, plug that into the V variable, and since the radius of one of the marbles is 3, plug that into the r variable. From here, we can solve for x: 
Firstly, solve the parentheses: 
Next, multiply 36 pi and x: 
Next, subtract 24 pi on both sides: 
Lastly, divide both sides by 36 pi, and your answer will be
, or B.
Answer:
The numbers are 28, 29 and 30
Step-by-step explanation:
We consider the first number as X, the second consecutive number is X+1 and the third is X + 2. The sum of these 3 numbers is 87, so:
X + X+1 +X+2 = 87
3x + 3 = 87
We substract 3 on both sides of the equation
3x + 3 - 3 = 87 - 3
3x = 84
We divide by 3 on both sides
x = 28
This means our numbers are 28, 29 and 30
