Well single number, meaning from 1 - 9. She has a higher chance of getting an odd number for sure, as there are more odd numbers on the dice :) So, the ratio is 4:5 and fraction: 4/5. %<span>44.444 is your answer :) 

Thank you,

A spherical iron ball 10 in. in diameter is coated with a layer of ice of uniform thickness. If the ice melts at a rate of 15 St
seraphim [82]

Answer:

a) Rate at which the thickness of the ice is decreasing, da/dt = -0.024 in/min

b) Rate at which the outer surface area is decreasing, dA/da = -4.22 in²/min

Step-by-step explanation:

The volume of the sphere, V = 4/3 πr³

The thickness of the ice = a

inner diameter = 10  in

inner radius = 10/2 = 5 in

outer radius = 5 + a

Therefore, volume of ice = volume of the outer radius - volume of the inner radius

V = 4/3 π (4+a)³ - 4/3 π4³

V = 4/3 π ( 4³ + 12a² + 48a + a³ -4³)

V = 4/3 π(a³ + 12a² + 48a)

dV/dt = 4/3 π (3a²da/dt + 24ada/dt + 48da/dt)

dV/dt = 4π(a²da/dt + 8ada/dt + 16da/dt)..............(1)

When a = 3 in, dV/dt = -15 m³/min

Substitute these values into equation (1)

-15 = 4π(9da/dt + 24 da/dt + 16da/dt)

-15/4π = 49da/dt

-1.194 = 49da/dt

da/dt = -1.194/49

da/dt = -0.024 in/min

b) How fast is the outer surface area of ice decreasing

The area of a sphere, A = 4πr²

The outer surface area of the sphere, A = 4π(4+a)²

dA/da = 8π (4+a) da/dt

a = 3 in, da/dt = -0.024 in/min

dA/da = 8π(4+3)*(-0.024)

dA/da = -4.22 in²/min

The perimeter of Dawna's new flat screen television is 112 inches. The ratio of its length to width is 4:3. Wire and solve an al
Dmitry_Shevchenko [17]
Hey there,
Length = 4x
Width = 3x
Perimeter = 112 inches
4x + 3x + 4x + 3x = 112 inches
14x = 112 inches
x = 112 inches / 14
   = 8 inches
Length = 8 inches x 4
            = 32 inches
Width = 8 inches x 3
          = 24 inches

 Hope this helps :))
