How would you convert a mass in centigrams to a mass in milligrams?

Answers

Basically, add a zero, since that is one step down on the Metric Conversion Chart. (I'll add that at the bottom!)

So if I had 50cm of a Shrimp Ramen Noodle Packet, I'd have 500mg of the Shrimp Ramen Noodle Packet!

Metric Conversion Chart-

All you have to do is add a 0

so if I had 10 centigrams of sugar it would be 100 milligrams of sugar.

$4,500, 9%, 3.5 years

Answers

A principle of $4500 amounts to $5,917.5 in 3.5 years at 9%.

What is simple interest?

We know simple interest (SI) is given by SI = (p×r×t)/100, where

p = principle, r = rate in percentage, and t = time in years.

Given, p = 4500, r = 9% and t = 3.5 years.

∴ SI = (4500×9×3.5)/100.

SI = $1417.5 and the amount is (4500 + 1417.5) = $5,917.5.

Ali says if two lines share a point they cannot be parallel do you agree explain

Answers

Yes, parallel lines do not touch each other ever.

How are parallel straight lines related?

Parallellines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.

Since the given parallel line has equation y = 2x + 2, thus its slope is 2 and thus, the slope of the needed line is 2 too.

We are given that Ali says if two lines share a point they cannot be parallel .

Horizontal refers to something that goes parallel to ground level. Of course it depends on from where you see that thing.

When you slice an object horizontally, you cut it parallel to ground.

We know that parallel linesdo not touch each other ever.

so that's make ali statement correct.

Yes, parallel lines do not touch ever, that's what makes them parallel.

you run 1 3/4 mile each day your friend runs 4 times as far as you do how far does your friend run each day

Answers

Answer:

7 miles your friend run each day.

Step-by-step explanation:

As per the statement:

You run $1(3)/(4)$ mile each day.

⇒ you run each day = $(7)/(4)$ miles.

It is also given that; Your friend runs 4 times as far as you do.

"4 times as far as you do" means $4 * (7)/(4) = 7$ miles

⇒ Your friend runs each day = 7 miles.

therefore, 7 miles your friend run each day

You have to multiply 1 3/4 and 4 so you can't multiply an mixed fraction with an improper fraction so 1 3/4 becomes 7/4 and now you get 28/16 and simplified it would be1 3/4

8 14/11 to improper fraction
