Answer:
1.256g = 1,256,000 micrograms
1.256g = 1256mg
1.256g = 0,001256kg
Step-by-step explanation:
This is a conversion of units problem, that can be solved by rules of three.
In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.
When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.
When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.
Unit conversion problems, like this one, is an example of a direct relationship between measures.
First step: 1.256g to micrograms
Each g has 1,000,000 ug. So:
1g - 1,000,000 ug
1.256g - xug
x = 1,000,000*1.256
x = 1,256,000 micrograms
Second step: 1.256g to mg
Each g has 1,000 mg. So:
1g - 1,000mg
1.256g - xmg
x = 1,000*1.256
x = 1256mg
Final step: 1.256g to kg
Each kg has 1,000g. So:
1kg - 1,000g
xkg - 1.256g
1,000x = 1.256

x = 0,001256kg
They both get their cars washed on every 60th day.
You can solve this equation by finding the lcm (least common multiple):
15 30 45 60 75 90 105
20 40 60 80 100
The lowest common multiple is 60 as it is the first multiple the two have in common.
So, in sixty days, they’ll both get their car washed again
Answer:
C. sides of 3, 4 and 7
can't form a triangle.
the longest side (7) must be shorter than the sum of the other 2 sides.
Step-by-step explanation:
The percentage of 4c in the expression 0.2c is 2000%
<h3>How to determine the percentage of 4c?</h3>
The expression is given as:
0.2c
The percentage of 4c is then calculated as:
4c/0.2c
Evaluate the quotient
20
Express as percentage
2000%
Hence, the percentage of 4c in 0.2c is 2000%
