Comment on units conversion
Units conversion is easily done using conversion factors that have a value of 1. That is, the value of the numerator is equal to the value of the denominator. (12 in = 1 ft, for example). The numerator units are chosen to match units you want, while the denominator units are chosen to match units you want to cancel.
Here, we convert in³ to cm³ to lb using conversion factors given and ones we know.
Answer:
<h2>32.25 necklaces</h2>
Step-by-step explanation:
Given that the expected profit upon deduction of booth rent and material cost is at least $300
Given
let the number of necklaces be x
booth rent= $200
The cost of materials for the necklaces = $4.5x
the selling price for all the necklaces =$20x
total expenses= booth rent+cost of material = 200+4.5x
profit = selling price -total expenses
20x-300>200+4.5x+
B. the possible solution is the value of x i.e the number of necklaces to
be sold to make a profit of $300
20x-300>200+4.5x
20x-4.5x=200+300
15.5x=500
x=500/15.5
x=32.25
The Jewelry artist must have to sell a total of approximately 32.25 necklaces
Population of Zimbabwe in 2003 = 12.6 million
which is 1 million more than 4 times the population in 1950
<span>approximate population p of Zimbabwe in 1950 = ?
12.6 million = </span>12,600,000
and 1 million = 1,000,000
The equation becomes:
12,600,000=1,000,000+4p
where p is the
population in 1950
now solve for p,
12,600,000-1,000,000=4p
11,600,000=4p
11,600,000/4=p
p=2,900,000
which is the
population in 1950
