QUESTIONS WITH DETAILED VERIFIED ANSWERS (100% CORRECT
ANSWERS) /ALREADY GRADED A+
PEMDAS - (answer)(parenthesis, exponents, multiplication, division, addition,
subtraction) work left to right
Exponential Notation - (answer)Ex: 6^4, 2^3, 9^10, etc.
Expanded Form - (answer)Ex: 7x7x7, 6x6, 2x2x2x2x2, etc.
Standard Notation - (answer)Ex: 5^2= 25; 25 is the standard notation (the answer or
solution)
+x+ - (answer)=+
+x- - (answer)=-
-x- - (answer)=+
Adding or Subtracting fractions - (answer)You need a common denominator
Multiplying fractions - (answer)no special rule, just multiply Ex: 2/5 x 3/9= 6/45
Dividing fractions - (answer)flip 2nd fraction and multiply Ex: 2/5 divided by 3/9= 2/5 x
9/3
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
Acute angle - (answer)between 0 degrees and 90 degrees
Obtuse angle - (answer)between 90 degrees and 180 degrees
Complementary angles - (answer)2 angles that have the sum of 90 degrees
Supplementary angles - (answer)2 angles that have the sum of 180 degrees
the sum of the angle measures in a triangle - (answer)180 degrees
Acute triangle - (answer)All angles are acute
Right triangle - (answer)One angle is right
Obtuse triangle - (answer)One angle is obtuse
Scalene triangle - (answer)All sides have different lengths
Isosceles triangle - (answer)At least 2 sides have the same length
