Answer:
75%
Step-by-step explanation:
One way to find this out is to divide 15 by 20
15/20 can be simplified into 0.75.
Another example:
Let's say a student does absolutely horrendus on the test, and gets only 4 questions correct out of 20. You can do 4/20 which is 0.2 in decimal form. (You can use a calculator.) This means that in this example, this student got a 20% on the test.
It is pi x 11(x2 to get diameter) so it would be 69.08...
<em>Answer:</em>
<em>(r + 9)(r - 3)</em>
<em>Step-by-step explanation:</em>
<em>r² + 6r - 27 =</em>
<em>= r² + 9r - 3r - 27</em>
<em>= r(r + 9) - 3(r + 9)</em>
<em>= (r + 9)(r - 3)</em>
