30,100= 2,150x
Total x=number per minute
divide 2,150 0n both sides
30,100= 2,150x
____
2,150
Cross it out. Your only left with x.
Then divide 30,100 by 2,150 = 14
x= 14 minutes it will take to completely descend
Your welcome.
Circumference = 3.1415 (pi) x diameter
44 = 3.1414 x diameter
Diameter = 14.006 or 14 (aprox)
Definitely irrational, and I'd say 1.4
The rule for the reflection of shape A over the line y = -x is (x, y) ⇒ (-y, -x)
<h3>What is a transformation?</h3>
Transformation is the movement of a point from its initial location to a new location. Types of transformation are <em>translation, rotation, reflection and dilation.</em>
Dilation is the increase or decrease in the size of a figure.

Looking at the image I have attached (with MN being the midsegment of the trapezoid), For any PQ with P and Q lying on the bases of the trapezoid there exists ON with O being the point of intersection between PQ and MN. ON must be parallel to PC because ON is part of MN and PC is a part of DC, and MN and DC are parallel. And N must be the midpoint of CB because MN is the midsegment of the trapezoid, so MN must bisect CB. And since ON is parallel to PC and bisects CB, that means it is a midsegment of QBCP and must bisect PQ.
