Franklin weighs 46,266,400 milligrams and his baby brother weighs 4,535.9 grams. What la there total weight in kilograms?
amm1812

Answer:

Exact: 50.8064

Rounded to nearest whole #: 51

Step-by-step explanation:

Our units are: Milligrams, Grams, and Kilograms. For Reference;

Miligrams are 1 million (1,000,000) times smaller than kilos.

Grams are 1 thousand (1,000) times smaller than kilos.

If we divide Franklins weight, 46,266,400 mg, by 1,000,000, our answer is  46.2664 kg, 46 if we round it.

Now, for his baby brother, his weight is 4,535.9 g. Divide this by 1000, and you should get 4.5359 kg, 4.5 if we round it to the nearest tenth.

Now simply add our two answers and you have both of their weight combined.

This is pretty simple, you simply can move the decimal point a certain amount of times dependent on how bigger or smaller your unit is. If we were converting kilograms to grams, we would multiply a value by 1,000, and the inverse for grams to kilograms, which moves the decimal point 3 times.

Any questions? Just ask me. Thanks.

Simplify x+6/12 over x-8/10 ...?
Kipish [7]
(x + 6) / 12 / (x - 8) / 10 =
(x + 6) 10 / (x - 8) 12 =
(x + 6) 5 / (x - 8) 6

The correct answer is (x + 6) 5 / (x - 8) 6
First you multiply (x+6) by 10 and (x-8) by 12, and then you divide both 10 and 12 by 2.

PLEASE HELP 20 POINTS!
Natasha2012 [34]
Sure you do.

What is the x-intercept ? It's the point where the graph crosses the x-axis.
But y=0 at every point on the x-axis !  So the x-intercept is the point where

5x + 3(0) = k
5x = k
<u>x = 0.2 k</u>


Similarly ... What is the y-intercept ? It's the point where the graph crosses the
y-axis. But x=0 at every point on the y-axis !  So the y-intercept is the point where

5(0) + 3y = k
3y = k
<u>y = k/3</u>

The sum of the x- and y-intercepts is 32.5 .
0.2k + k/3 = 32.5
Multiply each side by 5 :
k + 5k/3 = 162.5
Multiply each side by 3 :
3k + 5k = 487.5
8k = 487.5
Divide each side by 8 :
<u>k = 60.9375 </u>

The x-intercept is (0.2k, 0) = the point (12.1875, 0) .

The y-intercept is (0, k/3) = the point (0, 20.3125) .

Those are the two points. Now it wants you to find the distance between them.
Do you remember how to find the distance between 2 points ?

Find the (difference of their x-values) and square it.
Find the (difference of their y-values) and square it.
Add the two squares together.
Take the square root of the sum.
That's the distance between the points.

(12.1875)² + (20.3125)² = the square of the distance.

If you don't get 23.688 for the distance, then check your arithmetic.
