Write 4 different mixed decimals that equal 11 wholes

Softa [21]3 years ago

There are an infinite number of answers. One possible answer is 3.5+1.2+2.4+3.9=11. The explanation of how I arrived at this follows: A mixed decimal is a whole number followed by a fractional part so an example would be 3.4 or 2.5. To get 4 different mixed decimals that sum to 11 follow these steps: 1. Start with 11 and subtract any mixed decimal from 11 that is smaller than 11. So I will subtract 3.5    11-3.5=7.52. Take the 7.5 from the last step and subtract another mixed decimal from 7.5 that is smaller than 7.5. I will subtract         1.2    7.5-1.2=6.33. Take the 6.3 and subtract another mixed decimal from 6.3 that is smaller than 6.3. I will subtract 2.4    6.3-2.4=3.94. Now I take all of the numbers that I subtracted and add them together along with the 3.9 that was left over and I get       3.5+1.2+2.4+3.9=11

I hope that this helps you! =D

Type the correct answer in each box. (____)
trapecia [35]

Answer:

1. -16; 2. +64; 3. 16

Step-by-step explanation:

The formula for the volume of a cylinder is

V = πr²x

Data:

r = (x - 8)   mm

V = 1024π mm³

Calculations:

1. Find the cubic equation  

V = πr²h

1024π = π(x - 8)² × x

Divide each side by π

1024 = x(x - 8)²  

1024 = x(x² - 16x  + 64)

1024 =    x³ - 16x² + 64x

x³ - 16x² + 64x - 1024 = 0

2. Solve the cubic equation

The general formula for a third-degree polynomial is

f(x) = ax³ + bx² + cx + d

Your polynomial is  

f(x) = x³ - 16x² + 64x - 1024

a = 1; d = -1024

According to the <em>rational roots theorem</em>, the possible roots are

factors of d/factors of a

Factors of d = ±1, ±2, ±4, ±8, ±16, ± 32, ± 64, ±128, ±256, ±512, ±1024

Factors of a = ±1

Potential roots are x = ±1, ±2, ±4, ±8, ±16, ± 32, ± 64, ±128, ±256, ±512, ±1024

That's a lot of possibilities to check by trial and error. I will just use the one that works.

Try x = 16 by synthetic division.

16|1  -16   64  -1024

  <u>|     16     0   1024 </u>

   1     0   64        0

So,

(x³ - 16x² + 64x - 1024)/(x – 16) = x² + 64

and

(x - 16)(x² + 64) = 0

x - 16 = 0        x² + 64 =    0

     x = 16       x²         = -64

                       x          =  ±8i

There is only one real root: x = 16 mm
