QUESTIONS WITH SOLUTIONS GRADED A+
⩥ Exponential Notation. Answer: 6⁴, 3², 4⁶
⩥ Standard Notation. Answer: 5² = 25
25 is the standard notation
( answer to solution )
⩥ Adding or Subtracting fractions. Answer: requires a common
denominator
⩥ Multiplying fractions. Answer: no special rules, multiply across
( ex: ⅗ ⋅ ⅚ = ½ )
⩥ Dividing fractions. Answer: multiply by the reciprocal
( ex : 1/4 ÷ 5/3 = 1/4 ⋅ 3/5 )
⩥ Solving Equations w/ fractions. Answer: either multiply both sides of
the equation by the reciprocal of the fraction, or multiply both sides of
the equation by the denominator of the fraction
,⩥ Percent Increase or Decrease problems. Answer: Formula: amount of
change/ original number. Ex: Find the percent decrease if the price
changes from $60 to $39. 60-39= 21. amount of change= $21 original
number= $60. $21/$60= 0.35. Convert to percents. 0.35= 35%
⩥ Interest. Answer: Formula: interest= principal x rate x time (I=
PxRxT)
⩥ Point. Answer: -A point has no dimension
-It is represented by a dot
-A point is written using an upper-case letter
⩥ Line. Answer: -A line has one dimension
-Named using any two point on a line w a two sided arrow above them
-It can also be named using a lower-case cursive letter
⩥ Collinear Points. Answer: Points that are on the same line
⩥ Plane. Answer: -A plane has two dimensions
-It is represented by a shape that looks like a floor or a wall, but it
extends w/o an end
-Through any three points not on the same line there is exactly one plane
, -A plane is written using 3 non-collinear points or with upper-case
cursive letter
⩥ Coplanar points. Answer: Points that lie in the same plane
⩥ Line Segment. Answer: A line segment is named using both end
points with a line above them
⩥ Ray. Answer: A ray is named using its endpoint first and then any
other point on the ray pointing to the right above them
⩥ Intersecting lines. Answer: 2 lines that share exactly one point
⩥ Parallel lines. Answer: 2 lines that are always the same distance apart
and never touch
⩥ Perpendicular lines. Answer: The relationship between 2 lines which
meet at a right angle (90degrees). Perpendicular lines= 2 lines intersect
at a right angle
⩥ Right angle. Answer: 90 degrees
⩥ Straight angle. Answer: 180 degrees
