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.

How do I determine if a limit exist considering how it looks on a graph? Can I determine if a limit exists solely from the graph

Allushta [10]

Answer: See below

Step-by-step explanation:

1. At x=1, the limit does not exist. If you see an open circle on the graph like you do here, you know that the function is discontinuous. This graph actually shows a jump discontinuity at x=1.

2. You can determine if a limit exists by solely looking at the graph. Unfortunately in this case, f(1)=1 and $\lim_{x \to \ 1^-} f(x)$ are not equal to each other. Therefore, the limit does not exist.

Sharon bought some bottles of water at Randolph's Grocery. Use the graph shown to answer the question

alexandr1967 [171]

Answer:

A. Sharon spent $10 to buy 25 water bottles at Randolph's Grocery

Step-by-step explanation:

I know this because for 10 bottles it's $4.00 so you would do that twice which would be $8 and then for 5 bottles it's $2.00.

So all together that would be 25 bottles and the total cost would be the $10
