Answer:

I like A the best; B also works.

Step-by-step explanation:

Choices C and D do not result in centimeters, so are useless for this problem.

Though you can use the conversion factor 1 ft = 30.48 cm, I find it convenient to remember the conversion 1 in = 2.54 cm. The first factor with choice B gets you there:

... 1 yd = 3 ft = 3×30.48 cm = 91.44 cm . . . . . . can do in your head

As does choice A:

... 1 yd = 36 in = 36×2.54 cm = 91.44 cm . . . . . probably requires a calculator

The path you understand and that works for you is the "best" path.

After a 75% reduction, you purchase a new DVD player on sale for $136. What was the original price of the DVD player
iogann1982 [59]

Answer:

$544

Step-by-step explanation:

To determine the original price of the DVD player considering that you know that it had a 75% reduction, you can use a rule of three as the price of $136 represents 25% of the original price and with this you can calculate the price that represents 100%:

$136 → 25%

  x    ← 100%

x=(136*100)/25=$544

According to this, the answer is that the original price of the DVD player was $544.

A square piece of paper has an area of x2 square units. A
Dmitry_Shevchenko [17]

Answer:

Length of rectangular strip = 12

area of rectangular strip =   2*12 = 24

Area of square =  x^2 = 12^2 = 144

Step-by-step explanation:

Area of square x^2

area of rectangle is given by length * width

Length of rectangular strip = x

width of rectangular strip = 2

area of rectangular strip =  length * width = 2*x = 2x

Area of square piece of paper when  rectangular strip is taken away from it

= Area of square - area of rectangular strip

= x^2 -2x

It is given that Area of square piece of paper when  rectangular strip is taken away from it is 120 square units.

Thus,

x^2 -2x = 120\\=> x^2 -2x -120 = 0\\=> x^2 -12x +10x-120\\=> x(x-12) +10(x-12)\\=> (x+10)(x-12) = 0\\\\

Thus,

either x+10 = 0 or x -12= 0

x = -10 or x = 12

but length cannot  be negative hence neglecting x = -10

hence value of x is 12.

Hence,

Length of rectangular strip = 12

area of rectangular strip =   2*12 = 24

Area of square =  x^2 = 12^2 = 144

the variable Z is invery proportional to X. when X is 3, Z has the value 6. what is the value of Z when X = 12
MrMuchimi

"inversely proportional," please.

z = k/x

When x is 3, z = 6; find k: 6 = k/3, or k = 18.

Then z = 18/x. When x = 12, z = 18/12 = 2/3 (answer)
