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
10' x 12' are the dimensions for the floor and roof, both of which will not be covered with wallpaper.
The room will have two identical walls with the following dimensions:
10 x 8
12 x 8
The total area to be covered is:
2 x 10 x 8 + 2 x 12 x 8
Total area = 352 square feet
Answer:
69% increase (nice)
Step-by-step explanation:
2900 / 4200 = .69047
Round up the answer to nearest hundredth
.69
turn it into a percentage
69%
The equation system is
1.25x+0.75 (92-x)=87.5
Solve for x
1.25x+69-0.75x=87.5
0.5x+69=87.5
0.5x=87.5-69
0.5x=18.5
X=18.5÷0.5
X=37 units of candy bras
(92-37)=55 units of water bottles
Mr's Powell's class sold more items
Let's look which class earned more
Mr's Powell's class earned
55×0.75=41.25
Mr's Rodman's class earned
37×1.25=46.25
So from above
Mr's Rodman's class earned more
Hope it helps!
