If this question had an answer choice I would say it will take the second skater 20 seconds to pass the first one. If you graph it the graph will tell you this odd fraction 40/2 simplify equals a fair 20. With that being said answer= 20 seconds.

Answer:
Side AB is <em>10 cm</em>.
Step-by-step explanation:
The given quadrilaterals <em>ABCD</em> and <em>EFGH </em>are similar.
From the given figure, we can observe the following angles and sides are corresponding.
Ratio of corresponding sides will be equal:
AB:EF = BC: FG = CD:GH = DA:HE
We have to find the side AB.
Given the sides
EF = 5 cm
BC = 9 cm
DA = 8 cm
EH = 4 cm
So, ratio DA:EH = 8:4 = 2:1
We know that ratio of corresponding sides will be same:
AB:EF = DA:EH
So, side <em>AB</em> is 10 cm.
Answer:
Check below
Step-by-step explanation:
1) Check the rectangle below with a line k, the axis of rotation in the center of the figure.
2) Since it has a perimeter of 32 units and it is to be rotated about the line, the solid to be created it is a cylinder. As you can see below.
3) Let's calculate its radius, based on the information given, i.e. the perimeter:
Since the line of rotation is the center, and the radius is half the line segment of the basis, then the radius is 5.
