Using proportions, it is found that the angular velocity at the tip of the blade is of 753.98 radians per minute.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Each revolution has 2\pi radians, hence in one minute, the 120 revolutions will have a measure in radians of:

M = 120 x 2pi = 240pi = 753.98

Hence the angular velocity is of 753.98 radians per minute.

A quadrilateral is drawn on a coordinate plane with vertices at W(-3,1) X(-1,5). Y(0, 3), and Z(-2,-1).
lbvjy [14]

The actions that prove that the quadrilateral is a parallelogram are:

  • Use the slope formula on each side of the quadrilateral and show that opposite sides have the same slope.
  • Use the distance formula on each side of the quadrilateral and show that opposite sides have the same length.

<h3>Quadrilaterals</h3>

Quadrilaterals are polygons that have four sides and four corners

<h3>Parallelograms</h3>

Parallelograms are quadrilaterals that have parallel and congruent opposite sides

For the quadrilateral to be a parallelogram, then the opposite sides must be congruent.

This can be proved using the distance formula

Also, for the quadrilateral to be a parallelogram, then the opposite sides must be parallel.

This can be proved using the slope formula

Hence, the possible actions are (a) and (b)

Which sets of side lengths could form a triangle
olga2289 [7]
A 
No 9 is bigger than the other 2 added together.
B
3+ 6 = 9. A triangle cannot be formed.
C
4+5 = 9. A triangle cannot be formed. The shorter two will just make the length of the longest side. No triangle made.
D
Yes 4+6 > 9 A triangle will be formed.
E
Yes 5 + 5 = 10 which is greater than 9. A triangle will be formed.

Can you estimate 7533
Oduvanchick [21]

Based on your comment I assume you want to find 7,533 subtracted by 7,200. To estimate this, round 7,533 to the hundreds place, so 7,533 becomes 7,500.

7,500 - 7,200 = 300, using mental math.
