Ommited Answer Choices:
A. 4 inches, 4 inches, 4 inches
B. 3 inches, 3 inches, 3 inches
C. 3 inches, 3 inches, 2 inches
D. 2 inches, 2 inches, 3 inches
Answer:
C. 3 inches, 3 inches, 2 inches
Step-by-step explanation:
The ratio of the corresponding lengths of two similar polygons will always be equal.
Thus, the ratio of the smaller sides of both similar isosceles ∆ should equal the ratio of the other sides.
Thus, from the options given, the side measurements that could be that of the smaller triangle are: 3 inches, 3 inches, 2 inches.
This is because: ratio of one of the equal side of the larger triangle to one of the equal side of the smaller triangle equal ratio of the shortest side of the bigger triangle to the shortest side of the smaller triangle.
Thus: 6/3 = 4/2 = 2.

<h2>
Method 1: Creating and Solving Equations</h2>
Step 1: Find the amount drilled per hour
To do this, we have to divide the amount drilled by the number of hours it took to drill and find how much is being drilled per hour.
(I know it's a mouthful)
-72ft = 24x, where x is the amount drilled per hour
-72ft ÷ 24 = x
-3ft = x
-3ft per hour
Step 2: Find how many hours it takes to drill to -132 ft
Since we know the rate of drilling per hour, we can divide the target amount by the amount drilled per hour
-132 ÷ -3 = y, where y is the number of hours it takes
44 = y
y = 44
It will take a total of 44 hours to drill to -132 ft
<h2>Method 2: Proportions</h2>
We can set up a proportion like this, where we know that it takes 24 hours to drill 72 ft, but we don't know how long it takes to drill 132 feet
Cross multiply
Simplify
Divide both sides by -72
It will take a total of 44 hours to dig to -132 ft

Answer:
Lin = 8.2 m/s x 25 s =<u> 205 m </u> (<em>Finish Point)</em>
Elena = V = 250 m / 28 s <u>V = 8.93/s </u> (<em>Velocity</em>)
Diego = -8.1 m/s x 32 s =<u> -259.2 meters</u> (<em>Finish Point</em>)
Andre = V = -285 m /35 s V= -8.14ms (<em>Velocity</em>)

I'll take a stab here
Originally I thought this was something complicated, like surface area or volume, in which the answer would have been hard to determine given the fact that trash bins are different widths at the top and bottom.
However, with the info you just gave me, I believe this is more of a simple circumference problem.
So, in math, you have a triangle of equations relating to pi. R*2=Diamater, Diameter*3.14=circumference, circumference/3.14=Diameter, etc.
So, here you are given the diameter of the top and radius of the bottom of the bin. The top is 25 cm (d), the bottom is 10 cm (r). ACROSS, First, you want to make both measurements the same.
So, leave 25cm (d) alone, but change the 10 cm (r) to diameter (d). So, radius *2= diameter, so 10*2=20, so the top is 25 cm (d) and the bottom is 20 cm (d).
Next you need to find the circumference (around the edge length, imagine the wrapper on a water bottle, that wrapper goes completely around the bottle and comes back to touch its end. That's circumference.)
So, circumference is diameter * pi (3.14, calculated originally by Archimedes, but pi is actually infinite digits)
So, 25*3.14 (use a calculator as expected) =78.5
And 20*3.14 =62.8
Add the two together to find out how much length of whatever she wants to put on the bin she needs.
78.5+62.8=141.3
You can round and say she needs 142 cm of decoration.
This is assuming that she wants to put 2 decorations on the bin, one on the top, one on the bottom, going around the bin, as that is what I understood from the question.
