Answer:

Step-by-step explanation:
<h3>45° - 45° - 90° triangle:</h3>
The ratio of sides of 45 - 45 - 90 triangle is a : a : a√2.
a is the side opposite to 45°.
From the figure, a = 5√11
The side opposite to 90° is a√2.
y = a√2

Answer:
-1
Step-by-step explanation:
2(.5n-3)=n-0.25(12-12n)
first you distribute whatever is on the outside of the parenthesis to the inside of the parenthesis
1n-6=n-3+3n
then you combine like terms and end up with
1n-6=-3+4n
add 6 to each side to get
n=3+4n
subtract 4n from each side to get
-3n=3
divide -3 from each side to get
n=-1
Its a chemical element, and it is surrounded by electrons.
Using the relation of velocity, distance and time, it is found that 35 represents Michelle's velocity.
-----------------------------
Velocity is <u>distance divided by time</u>, then:

Kevin drove for 3.25 hours, thus
. The distance drove by Kevin is:


Michelle drove for 1.5 hours, thus
. The distance drove by Michelle is:


The total distance is:


Comparing to the expression:

We get that 42 is Kevin's speed and 35 is Michelle's speed.
