Change the mixed fractions to improper fractions.
To do this, multiply the whole number part by the denominator. Add that to the numerator. Then write the result on top of the denominator.
You would now have:
Change the division sign to a multiplication sign by turning the second fraction upside down.
That is,
The answer is:
This can be simplified to:
Answer:
LCM = 20, GCF = 9
Step-by-step explanation:
Answer:
See attached for a "Neat" quadratic formula.
a = -1
b = 2
c = 1
x = [-2 +- sqr root( 4 -4*-1*1)] / -2
x = [-2 +- sqr root( 4 -4*-1*1)] / -2
x = [-2 +- sqr root(8)] / -2
x1 = (-2 +2.8284271247) / -2
x1 = .8284271247 / -2
x1 = -0.41421
x2 = (-2 -2.8284271247) / -2
x2 = ( -4.8284271247) / -2
x2 = 2.4142135624
So the equation has the positive solution of
2.4142135624

Answer:
252pi (B)
Step-by-step explanation:
Find the area of the bases (2 * pi * r^2)
r = 6, so:
72pi = total area of bases
Find the area of the side (pi * 2 * r * h)
r = 6 and 15 = h, so:
180 pi = area of the side
180pi + 72pi = 252pi (B)
