Formula to convert lbs to kilos

Convert 10 lbs to kilos

Divide lbs by 2.205

Exp

10 ÷ 2.2 = 4.454545

Formula to convert kilos into lbs

10 kilos is how many lbs

Kilo x 2.2 = lbs

10 kilos X 2.2 = 22 lbs

Formula to convert miles into kilometers

1 mile = how many kilometers

Miles x 1.6 = kilometer

1 x 1.6 = 1.6 kilometers

Formula to convert kilómetros to miles

50 kilómetros is how many miles

kilómetros ÷ 1.6 = Miles

50 kilómetros ÷ 1.6 = 31.06 miles

Formula for the perimeter of a square

4 x side = Perimeter

Formula for area of a rectangle

Length X Width

Formula for Circumference of a circle

C = 3.14 × Diameter

What is the difference between radius, circumference, diameter

Radius = half way across the middle/ half the diameter

Circumference = A line around the perimeter of the circle

Diameter = a straight line through the center of a circle

Formula for area of a square

A = s² (s = side of the square)

Formula for area of a circle

A = 3.14 × r² (r = radius)

Formula for the volume of a box

V = lwh

Volume = length × width × height

Surface area for a cylinder

(May not need this)

S = 2×3.14×r² + 2×3.14×r×h

Perimeter for a rectangle

P= 2l + 2w

Perimeter = 2 × length + 2 × width

Pythagorean theorem and what it’s used for

a² + b² = c² on a Right triangle

Used to determine if a triangle is a “Right Triangle “

Used to determine length of missing length of Right Triangle

Volume of a Sphere

(I don’t think you need to memorize this)

V = 4/3 × 3.14 × r³

Formula for area of a triangle

A= .5 × b × h

Area = .5 x base x height

Formula for volume of a cylinder

V= 3.14 × r² x h

Formula for Volume of a cone.

(May not need to memorize)

V = 1/3 × 3.14× r² × h

Volume = .333 × 3.14 × radius²× height

Surface area fórmula

2 × (L × W)

+ 2 × (L × H)

+ 2 × (W × H)

Surface area

Formula to convert inches to centimeters

Inches × 2.54 = cm

Formula to convert centimeters to inches

C ÷ 2.54 = inches

Sum of angles on a triangle

180°

What do you need to calculate Slope “m”

2 ordered pairs (0,2) (7, 14)

Formula

m = y² - y¹

———–

x² - x¹

In an ordered pair which is the “x” value and which is the “y” value

(0,10)

0 = x value

10 = y value

Again, which is the vertical and which is the horizontal axis on a grid?

Vertical = Y

Horizontal = X

Which is the dependent/ Independent variable on a graph

X or Horizontal axis: Independent

Y or Vertical axis: Dependent

In a slope which is the “x” value and which is the “y”

Exp. 1/2

1 is the Y

2 is the X

What is the formula for Slope Intercept Form?

Y = mx + b

Y: Point on the Graph

M: Slope, 1/2 “Rise over Run”

b: Y Intercept
