The answer to this question is 96 because 800/100 = 8 which is 1% of the 800 students. then times it by 12 to give you the answer
SA = 1/2 Pl + B ; P(perimeter of base) , l(slant height) , B(area of base)
= 1/2 (4)(8) (6) + 8^2
= 1/2 (32)(6) + 64
= 96 + 64
= 160

The expression x²-14x+31=63 is a quadratic
equation. To solve it, you must order it:
x²-14x+31-63=0
x²-14x-32=0
Then, you must apply the quadratic formula, which is shown
below:
x=(-b±√(b^2-4ac))/2a
So you have the values of a,b and c:
:
a=1
b=-14
c=-32
When you substitute those values
in the quadratic formula, you obtain:
x=(-(-14)±√((-14)^2-4(1)(-32))/2(1)
x1=-2
x2=16
So, the correct option is the third one: x=-2 or x=16
Answer:
Zero Slope
Step-by-step explanation:
its zero slope because it has no rise
example: rise 0 over 1
Zero slope: 0/1
undefined slope: 1/0
positive slope : 3/4
negative slope: -9/6
