what does a right angle have to equal to?
900
which kind of numbers does this letter represent
N
natural numbers
what type of graph is this
box and whisker plot
what is the expression for 3x2 - 5x - y
binomials
what is the formula to find A in a right triangle
C2 - B2 = A2
if the inscribed is 240 what does the central angle equal to
480
because the central angle is always 2x the inscribed angle
what does R W and I represent
whole numbers real numbers and irrational numbers
what is the median
85
it is 85 because the line inside the box is above 85
2x4 - 5x + 4
trinomials
2 of the sides on the triangle are 26 and 17 what is C
a2 + b2 = c2
= 262 + 172 = c2
= 676 + 289
=9652
= 31.06

3600
what type of numbers does Q represent
can be written as a fraction
what does Q1 and Q3 mean
lower quartile
upper quarile
what does 3x + 5 -2x + 1 equal to
x + 6
3x - 2x =x
5+1 = 6
what is the formula for the surface area of a cone?
and what is the formula for the volume of a cylinder?
cone nr2 + nrs
2nr2 + 2nrh
if A equals 16 what does C equal in an inscribed angle
C=16
because C is opposite of A in a inscribed angle which means they are equal
which set of numbers does this letter represent
Z
and what does Z mean
integers
positive and negative numbers
where is Q1 Q2 and Q3 on this plot and where are the min and max
Q1=78
Q2= 85
Q3=93
min=67
max=96
Q1 is 78 because on the left edge on the box lines up with 78
Q3 is 93 because on the right side of the box lines up with 93
min is 67 because the line on the left side ends at 67
max is 96 because the line on the right side ends on 96
what does (6x2 -7x) - (-2x2 + 5x) equal to
8x2 - 12x
6x2 - 2x2 = 8x2
7x + 5x =12x
what is the formula for the surface area and volume of a triangle based pyramid
surface area
= bl + ah + bh + ch
volume
v= blh dived by 2
what must a triangle equal to?
