Volume is the product of the three dimensions...
V=xyz in this case:
V=3*10*5
V=150 yd^3
Answer: a) 2.27 g and b) 15384
Step-by-step explanation:
Given : An effervescent tablet has the following formula:
acetaminophen 325 mg,
calcium carbonate 280 mg,
citric acid 900 mg,
potassium bicarbonate 300 mg, and
sodium bicarbonate 465 mg.
a) When we add all quantities together , we get
The total weight of the ingredients in each tablet = 
Since, 1 gram = 1000 mg
Then, 
Now, 
∴ The total weight of the ingredients in each tablet = 2.27 g
b. 1 kg = 1000g and 1 g = 1000 mg
Then, 1 kg = 
⇒ 5 kg = 5000,000 mg
Now, The number of tablets could be made with a supply of 5 kg of acetaminophen will be :
Hence, the number of tablets could be made with a supply of 5 kg of acetaminophen= 15384
In order to convert a percent to the decimal, the number should be divided by 100 and remove the percentage sign.
<u>Step-by-step explanation:</u>
Percent stands for per hundred.
In order to convert a percent to the decimal, the number should be divided by 100 and remove the percentage sign.
Example – 75%
= 75/100
= 0.75
<u>To convert decimal to mixed fraction:</u>
1. Divide the given decimal number by the place of the decimal and remove the point from the numerator.
Example – 5.25
= 525/100
2. Simplify the fraction if possible.
Example = 525/100 = 21/4
3. Divide the numerator by the denominator.
On solving we get, 5 as the quotient and 1 as the remainder.
To convert into a mixed fraction = the remainder becomes the numerator and denominator remains the same
Mixed fraction becomes = 5 1/4
