6 0

Well 6,000 is actually equal to 1,000 x 6.

It turns out that 1,000 = 10 x 10 x 10 = 10^3

So the answer to your question is:

6 x 10^3

If 0.65 AU equal 1 inch how much would 0.05 AU equal and explain.

mart [117]

Answer:

0.05 AU corresponds to the 0.0769 Inches(<em>This calculation is not possible in real time world)</em>

Step-by-step explanation:

Given:

0.65 corresponds to 1 inch

To Find:

0.05 AU corresponds to how many inches.

Solution:

<em>The AU is astronomical unit which is preferred as the mean distance between earth and sun.</em>

<em>AU is too big unit and used in space distance calculation.</em>

But here for mathematical calculation,

0.65 AU corresponds to 1 inch

then 0.05 AU corresponds to x inch(es)

Now cross multiplying the quantities we get ,

0.65x=0.05*1

x=0.05/0.65

x=0.0769 inches corresponds to 0.05 AU

(Preferred for this example only)

<em>(Remember that this calculation is hypothetical and practically incorrect to use it).</em>

A tree that is 4 ft tall is growing at a rate of 1 ft each year a tree that is 12 feet tall is growing at a rate of 1/2 ft each

Andreyy89

Answer:

16 years

Step-by-step explanation:

Given data

For the first tree

let the expression for the height be

y=4+x--------------1

where y= the total height

4= the initial height

x= the number of years

For the second tree, the expression is

y=12+0.5x-------------2

Equate 1 and 2

4+x=12+0.5x

x-0.5x=12-4

0.5x= 8

x= 8/0.5

x=16

Hence it will take 16 years for both trees to have the same height

What is the simplified form of this expression 7(^3sqrt2x)-3(^3sqrt16x)-3(^3sqrt8x)

trasher [3.6K]

Answer:

<h2> $7 \sqrt[3]{2x} - 6 \sqrt[3]{2x} - 6x$ </h2>

Solution,

$7( \sqrt[3]{2x} ) - 3( \sqrt[3]{16x} ) - 3( \sqrt[3]{8x} ) \\ = 7 \sqrt[3]{2x} - 3 \times ( \sqrt[3]{2 \times 2 \times 2 \times 2x} - 3 \times \sqrt[3]{2 \times 2 \times 2x} \\ = 7 \sqrt[3]{2x} - 3 \times (2 \sqrt[3]{2} x) - 3 \times 2x \\ = 7 \sqrt[3]{2x} - 3 \times 2 \times \sqrt[3]{2x} - 3 \times 2x \\ = 7 \sqrt[3]{2x} - 6 \sqrt[3]{2x} - 6x$

Hope this helps...

Good luck on your assignment...
