How many milligrams are equal to 0.92 grams?
0.00092 mg
92 mg
920 mg
92,000 mg

Answers

Answer is 920 mg !!!

There are 920 milligrams in 0.92 grams from the unit conversion.

What is Unit conversion?

A statement of the connection between units that are used to alter the units of a measured quantity without affecting the value is called a conversion factor. A conversion ratio (or unit factor), if the numerator and denominator have the same value represented in various units, always equals one (1).

To find the milligrams in 0.92 grams.

Since there is 1000 milligram in 1 gram,

thus,

In 0.92 grams the total of milligrams will be = 0.92 * 1000

In 0.92 grams the total of milligrams will be = 920 milligrams

Therefore, there are 920 milligrams in 0.92 grams.

–7c2–c2+–5c2–2c2+8c2–9c2

Answers

Answer:

the answer is why is math so hard

Step-by-step explanation:

Duh

i would start by grouping them into sections because they’re all like terms.
(-7c2-c2) = -8c2
(-5c2-2c2)= -7c2
(8c2-9c2) =-c2
then add them all together.
-8c2-7c2-c2
since they’re all negative you can add them together but don’t forget the negative.
8+7=15
15+1 = 16
add the negative back in to get -16c2

Step-by-step explanation:

I used a calculator

I mean it’s pretty simple really! Just plug in 0.5 for all the a’s in the equation so you equation will look like this

0.5^2+ 0.4(0.5) and now that you have your equation solve it normally! Remember to use PEMDAS

So....

0.5^2= 0.25 first we do the exponent

.25+0.4(0.5) here’s what we have now

0.4(0.5) = 0.2 now we do multiplication

.25+0.2= .45 finally we do addition and

it will give us a result of .45 so your answers is B

Hayley has $155 in savings, and her brother Hank has $230. Hayley is saving $10 each week, and her brother is spending $15 each week. After how many weeks will their savings accounts have the same amount of money in them?

What is the best way to set up this word problem to solve?

15x+155=230+10x
15 x plus 155 is equal to 230 plus 10 x

155−15x=10x+230
155 minus 15 x is equal to 10 x plus 230

155+10x=230−15x
155 plus 10 x is equal to 230 minus 15 x

155−10x=230+15x

If its right mark me brainliest if its wrong report me.

Answer:

$155+$10x=$230-$15x

Step-by-step explanation:

weeks= x

$155+$10x=$230-$15x is the correct answer because hayley currently has $155 in her saving and you have to add the 10 dollars she saves each week which is 10x. On the other hand, her brother has $230 and spends $15 dollars every week so that is 15x.
