Answer:
The weight of the three blades together is 
Step-by-step explanation:
step 1
Find the area of the circle
The area of the circle is equal to
we have
assume
substitute
step 2
Find the area of the 3 blades
we know that
The area of the 3 blades represent a central angle of 60 degrees, so
its a 1/6 of the area of complete circle
step 3
Find the weight of the three blades together to the nearest gram
Answer:
<h2>8/15</h2>
Step-by-step explanation:
Answer: 
Step-by-step explanation:
For it to bisect the segment, we need to find the midpoint.
The midpoint is 
.
Now, for it to be perpendicular, we need to use the fact that perpendicular lines have slopes that are negative reciprocals of each other.
The slope of the given segment is 
, so the slope of the perpendicular bisector is 6.
Thus, the equation of the line in point-slope form is 
Answer:
A. Perpendicular
Step-by-step explanation:
When lines and/or points are in perpendicular to one another, the perpendicularity line between them measures the distance between both points and/or lines.
So to measure the distance between point c and line AB, a perpendicular line has to be drawn from c to AB or from AB to c. Either of these will arrive at the same result.
It should also be noted that the angle at the point of intersection of perpendicular lines is 90°.
<span>No, it doesn't. To find out if it's a right angled triangle, we use Pythagorean triple. It states that the square of the hypotenuse (the longest side) is equal to the sum of the squares of the opposite and adjacent sides. Obviously, the longest side, which is our hypotenuse is 24. So we want to find out whether the square of our hypotenuse is equal to the sum of the squares of the other two sides i. e 13 and 21.
24^ 2 = 576 ; 13^2 = 169 ; 21^2 = 441;
So is 576 = 169 + 441. An emphatic No: hence the triangle isn't right angled since it doesn't satisfy pythagorean triple.. A^2 is not equal to B^2 + C^2 where a is the hypotenuse and b and c the opposite and adjacent sides.</span>
