150 vehicles had passed Luann.
There are:
=> 6 cars
=> 10 trucks
=> 14 SUV
=> 15 minivans.
How many minivans would we expect to pass out of 150?
=> 6 + 10 + 14 + 15 = 45
=> 15 / 45 = x / 150, where 15 is the number of minivans, and 45 is the total number of vehicles that passed
=> 150 / 45 = 3.333333… repeating decimals
=> 3.333… * 15 = 50
x = 50, there will be 50 minivans that will pass in LUann

V = pi × r² h/3
V = pi × 5² 18/3
V = pi × 25 × 18/3
V = pi × 25 × 6
V = pi × 150
V = 150pi cm³
Your answer is B. 150pi cm³
Step-by-step explanation:
Percentage for Rollerblading
= Total - Percentage for Swimming - Percentage for Biking
= 100% - 43% - 15%
= 42%.
Check the picture below.
well, it's noteworthy to say that when dropping a perpendicular line from a right angle in a right triangleto the hypotenuse, we'd end up with 3 similar triangles, a Large a Medium and a Small one, all three similar.
3a)
is the Small similar to the Large one? well, let's notice, they both have a 90° angle and also they share the purple one, similar triangles by AA.
3b)
are the Medium and the Large one similar? well, let's notice, just like before, they both have a 90° and they also share the green one, similarity by AA.
3c)
are the Small and Medium similar?
if Large ~ Medium
and
Large ~ Small
then
Medium ~ Small.
