Answer:

12.56 feet

Step-by-step explanation:

The perimeter of a shape is the sum of all its side.

Since circle doesn't have "sides", the perimeter is the length of the whole circle. This has the name "circumference".

The circumference of a circle has the formula:

$C=2\pi r$

Where

C is the circumference (perimeter of a circle)

r is the radius

Given,

r = 2 feet

We substitute and find the circumference, using 3.14 as $\pi$ ,

$C=2\pi r\\C=2(3.14) (2)\\C=12.56$

Hence, the circumference is 12.56 feet

Please help asap!!<br> I think D is one of the answers but i'm not sure

vampirchik [111]

Answer: B, D, and maybe E. Check my explanation for 'E'

Step-by-step explanation:

There are a few ways of visualizing the expression, but Ill try to show it to easiest way possible.

$x^\frac{3}{2} =(x^3)^\frac{1}{2}$

Notice nothing was changed because of the property of exponents. An exponent to a power means to multiply them. A thing you should remember for all future cases is that the one-half power means square root. It is the exact same thing. Therefore the new expression I created is the square root of 'x' cubed.

A:) This would be equivalent to x^2/3

B:) This is equivalent to x^3/2 because the square root is the 1/2 power to the power of 3.

C:) This would be equivalent to x^2/3

D:) This is equivalent to x^3/2 because the square root is the 1/2 power, but multiplied by the power under the radical.

E:) If this answer is to the third power, then it is equivalent. I cannot tell from this picture.

Theresa’s computer at home has 1 terabyte of storage. How many more bits of storage does her computer have than the combined bit

posledela

Answer:

Not enough information provided

Step-by-step explanation:

To find the difference between one terabyte and the storage available to the other mediums, we would need to know the storage available to those mediums. They can all have potentially different amounts of storage space, so we have no way to answer that part of the question.

We can however find out how many bits her computer has. There are two lines of thought to follow though. kilo, mega, giga etc each generally note a multiple of 1000 in common terms. In computer tech though, the number 1024, or 2¹⁰, is often used instead.

Starting with the layman's powers of 10, a terabyte is a thousand gigabytes, which in turn is a thousand megabytes, which is a thousand kilobytes, which is a thousand bytes.

That means that a terabyte stores 1 × 10¹² bytes. A byte however is eight bits, giving us 8 × 10¹² bits.

Using the nerdier powers of 2 then, a byte is eight bits, so we'll call that 2³. We then go up by multiples of 2¹⁰. With the same logic above, a terabyte is 2¹⁰ gigabytes, which is 2¹⁰ megabytes, which is 2¹⁰ kilobytes, which is 2¹⁰ bytes. Adding the exponents up, then a terabyte would be 2⁴³ bits

So depending on whether you use the powers of ten or powers of 2 conventions, then a terabyte is either 8 × 10¹² bits, or 2⁴³ bits.

If you want to express the latter as a power of ten for proper scientific notation, then it would be 8.796093022208 × 10¹² - a rather useless way of expressing it, but just to cover all bases.

If the front of a playhouse is shown in a scale drawing and the height of the door is 1.8 inches. The scale that maps the drawin

tatyana61 [14]

Answer:

4.5 feet

Step-by-step explanation:

Here, we are concerned with calculating the actual height in feet of the door given the scale used in the maps drawing.

In the scale, scale to actual is 1 inch to 2.5 feet

let 1.8 inch scale = x actual feet

Thus mathematically, by cross multiplying; we have;

x = 2.5 * 1.8 = 4.5 feet
