Answer:
20%
Step-by-step explanation:
We can start by looking at it as a ratio, so 4 divided by 20 and 4/20 = 0.2, so that would be 20% viewing 1=100%.
Another way is
20 here is 100%, and for 20 to equal 100, we have to multiply it by 5. To balance it out, multiply the top by 5 as well, and 4 * 5 =20. Therefore, 4/20 = 20%
This has an domain of all real numbers
Answer:
x = 11m
Step-by-step explanation:
The longest side is the bottom (15m). If you look at the sides you can see that the side that measures 4m is parallel with the side that measures 15m. Anytime two sides overlap to make x, we can simplify by subtracting or adding. All we need to do is subtract to find the length of x.
15 - 4 = 11m
Answer:
Step-by-step explanation:
The formulas to find the radius are quite simple. If you know the diameter of the circle, use this formula:
If you don't know the diameter, but you know the circumference, you can use this equation:
If you know the area of the circle, use this equation:
Note that the area of a circle is essentially the total space, measured in square units, inside of the perimeter of a circle.
