D. 0.65
Step-by-step explanation:
0.20 + 0.15 + 0.30
= 0.65.
√5/11
<em>This</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>rational </em><em>number</em><em> </em><em>because</em><em> </em><em>rational</em><em> </em><em>numbers</em><em> </em><em>are</em><em> </em><em>values</em><em> </em><em>which</em><em> </em><em>can</em><em> </em><em>be</em><em> </em><em>expressed</em><em> </em><em>as</em><em> </em><em>a</em><em> </em><em>fraction</em><em> </em><em>and</em><em> </em><em>√</em><em>5</em><em>/</em><em>1</em><em>1</em><em> </em><em>is</em><em> </em><em>already</em><em> </em><em>a</em><em> </em><em>fraction</em><em>.</em>
How fast the distance between them decrease is 16mph
<h3>How to calculate the speed of an object?</h3>
Given the following parameters
Speed of the hiker = 6mph
If is it 3/11 the rate of a cyclist, then the rate of the cyclist will be:
6 = 3x/11
3x = 66
x = 22mph
Distance between them = 22 - 6
Distance between them = 16mph
Hence how fast the distance between them decreases is 16mph

Step-by-step explanation:
General quadratic equation: ax^2 + bx + c
where a is the coefficient of the quadratic term, b is the coefficient of the linear term and c is the independent term. Here the equation is: x^2 – 2x – 3, so a = 1, b = -2 and c = -3
Quadratic formula:
Replacing
