<span>Total households = 127,900,000
Proportion of households having remote control and not
7 : 3
7x + 3x = 127,900,000
10x = 127,900,000
x = 12,790,000
Households having remote control = 7x
= 7 X 12,790,000
= 89,530,000
Answer:
89,530,000 households have TV remote controls.</span>
The probability of hitting the black circle is closer to 0 than it is to 1. because: find area of circle ~ 3.14*r^2
which is 3.14 because the radius squared is 1. so 1*3.14= 3.14
and the area of the whiteness is 121.
subtract 3.14 from 121 and you get 117.86
this answer is closer to a 0 probability than the white space. the white space is closer to a probability of 1.

The volume formula of a pyramid is:
V =

x length x width x height
The given are
Length = 24 cm, Width = 18 cm, Height = 35 cm
Substitute the values to find the volume
V =

x 24 x 18 x 35
V = 5040 cm³
The height of the ball at ground level would be 0 feet.
Set h to 0 and solve for t:
Rewrite the equation as
-5t^2 -2t +49 = 0
Factor -1 out of the equation to get:
5t^2 + 2t -49 = 0
Use the quadratic formula:
-b +/- sqrt(b^2 -4(ac) / 2a
Where a = 5, b = 2 and c = -49
The quadratic formula becomes:
-2 +/-sqrt(2^2 – 4(5*-49) / (2*5)
Simplify to get :
T = -2 +/-sqrt246 / 10
T = 2.936 and – 3.336
Since the time has to be a positive value t = 2.936 seconds.
Rounded to the nearest hundredth = 2.94 seconds.
The reason that 9.6 is rational is because it can be turned into a fraction.
The fraction is 48/5.
Rational numbers are numbers that can be turned into a fraction, while irrational numbers a those who cannot be turned into a fraction.
