Complementary Angle 
=90° 

Discounted Prices 
Amt of discount/original price= % of reduction
% of reduction x 100 = final answer % 

Traveling/Gas Mileage/Avg Speed 
Gallons of gas used* mpg= total miles traveled
Miles traveled/avg speed= hours 

Movable Pulleys 
Provide mechanical advantage 

Hydrometers 
Use floats to measure gravity 

Mechanical Advantage in Pistons

a^2 x d^2= a1 x d1
a= area, d= displacement 

Levers 
First Class: Fulcrum is in the middle (scissors) Second Class: Fulcrum is at one end, load is in between (nutcrackers) Third Class: Fulcrum is at one end, effort is in between (tongs) 

The further away the fulcrum is from the resistance arm... 
The greater amount of force that is required to lift the weight and the higher the resistance arm will travel 

Potential Energy 
Energy stored in an object 

Kinetic Energy 
Energy in motion 

Ammeter 
Measures current flow in a circut 

Voltmeter 
Measures voltage 

Multimeter 
Measures voltage and current flow 

Newton's 1st law 
Object in motion will stay in motion; Object at rest will stay at rest 

Newton's 2nd Law 
Force= Mass x Acceleration 

Newton's 3rd Law

For every action there is an equal and opposite reaction


Weight= 
Mass x Gravity 

Pressure= 
Force/Area 

Voltage=

Current x Resistance


V= I x R 
Finds voltage drops across a current or a single resistor 

I= Q/T 
Current= Charge/Time 

Distance= 
Rate x Time 

Area of a right triangle 
A= 1/2b x h 

Area of a rectangle/parallelogram 
A=bh 

Area of a trapezoid 
A= 1/2(b1+b2)h 

Area of a circle 
A= πr^2 

Circumference of a circle 
C= 2πr or C= πd
r= radius, d= diameter 

Pythagorean Theorem 
a^2 + b^2 = c^2 

Trigonometric Functions 
Sine (sin), Cosine (cos), & Tangent (tan) 

SOHCAHTOA 
sin= opposite leg/hypotenuse cos= adjacent leg/hypotenuse tan= opposite leg/ adjacent leg


Simple Interest 
I=prt
I= interest p= principal r= rate t= time 

Compound Interest 
A= P(1+(r/n))^nt
A= amount accumulated after n years P= principal amount r= rate n= number of times interest is compounded t= time
