0.5,1:5,0.35,12/25,4/5 in least to greatest
Andre45 [30]


First we must convert all the values to one mathematical state. We shall convert each to its decimal figure.

a) 0.5 is already a decimal so we leave it alone

b) 1: 5 when simplified makes  1/6  = 0.16

c) 0.35 is already a decimal so we will not touch it.

d) 12/25  = 0.48

e) 4/5 = 0.8

so now we arrange these from the least to greatest:

b, c, a, d, e,

 now we equate this with the original values so the answer will be:

1:5,  0.35,  0.5,  12/25,  4/5

If the radius is 18 cm and the angle at centre of circle is 120° then the
PolarNik [594]

The area of a sector is 339.336 cm²

The area of a sector is defined to be as the region of space bounded by a boundary from the center of the circle.

It can be determined by using the formula:

\mathbf{A = \dfrac{\theta }{360}\times \pi r^2 }

Given that;

  • Radius r = 18 cm
  • Angle θ =  120°

Then. the area of the sector can be calculated as:

\mathbf{A = \dfrac{120}{360}\times \pi (18)^2 }

\mathbf{A = \dfrac{1}{3}\times 3.142 \times 324 }

A = 339.336 cm²

Let f(x) = x2 − 81. Find f−1(x).
Umnica [9.8K]
F(x) = x² - 81

Finding f⁻¹(x) the inverse function

Let y = f(x) and solve for x.

y = x² - 81

y + 81 = x²

x² = y + 81

x = √(y + 81)

Recall f(x) = y, that means x = f⁻¹(y)

x = √(y + 81)

f⁻¹(y) = √(y + 81)

Therefore   f⁻¹(x) = √(x + 81)
