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.
3.25 * 7.8 = 25.35
10^3 * 10^6 = 10^(3+6) = 10^9
so we have 25.35 * 10^9 but in scientific notation the first number mus be <10
so the answer is 2.535 * 10^10
Answer:
I think it is A
Step-by-step explanation:
This is a one step equation. Understanding that we know what he started out with, and what he he had left, we can set it up in two seperate equations. (Easy or Hard version if you prefer, or simple and more complex)
♡EASY♡
$32.00-$23.05= X
X= $8.95
♡"HARDER"♡
$32.00-X=$23.05
Subtract 32 from both sides.
-X=-$8.95
Multiply each side by -1.
-1(-x)=(-$8.95)-1
x=$8.95
Either way, Les spent $8.95 on food.
Well you can just keep adding 55 =1hr until you get to 400 the same with 45
