Write the number below in scientific notation, incorporating what you know about significant digits. 67,890,000

1 answer:

7 0

The answer would be: 67.89 x 10^6

The rules of significant numbers used:

- any non-zero digit is significant
- zeroes that are in the right side of the non-zero whole number would not be significant

Thus, only the significant numbers left in the equation:

67.89 x 10^6

Hi there!

Step-by-step explanation:

$Slope=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}$

$\frac{8-2}{4-1}=\frac{6}{3}=2$

So therefore, the slope is 2.

Final answer is 2.

*The answer must have a positive sign.*

I hope this helps you!

Have a nice day! :)

There are 7 animals a farmer's field.

sergey [27]

Answer:

2 cows and 5 chickens.

Step-by-step explanation:

NOTE: This will be solved using simultaneous equations.

Let x = cows and y = chickens

1. form two equations

4x + 2y = 18 ... (1)

x + y = 7 .... (2)

2. make y (or x) the subject of one equation

x + y = 7

y = 7 - x ... (3)

3. Substitute (3) into (1)

4x + 2( 7 - x) = 18

4. solve for x

4x + 14 - 2x = 18

2x = 4

x = 2

5. Now substitute x value into equation (2)

x + y = 7

2 + y = 7

y = 5

∴ cows (x) = 2

chickens (y) = 5

What's the difference between 6z and z6

Airida [17]

Simple..

there is a major difference between 6z and $z^{6}$

6z means: 6 times z

and

$z^{6}$ means: z to the power of 6(z*z*z*z*z*z)

An example...

make z=2...plug n chug..

6z----> 6(2)=12
and
$z^{6}$ ---> $2^{6}$ =64

As you can see..there is a major difference.

Thus, your answer.
