The population of camden, New Jersey has been decreasing by 0.12% a year on average. If this trend continues, and the population
Talja [164]
By the trend that is being given above, the population of New Jersey will only be 99.88% of the population from the previous year. It may be calculated through the following equation,
                               P(n) = P(0) x (1 - r)^n
Substituting the values from the given above,
                                  P(n) = 79,318 x (0.9988)^(2015 - 2006)
                                          = 78465.47
Thus, the population will approximately be 78,466.

Mixture question please help!! (will give brainliest to an answer with step-by-step)
Svetradugi [14.3K]

Answer:

83.3 g of 18-karat gold and 166.7 g of 12-karat gold

Step-by-step explanation:

24-karat gold is pure gold. The purity is 24/24 = 1 = 100% gold.

12-karat gold is 50% gold. The purity is 12/24 = 0.5 = 50% gold.

14-karat gold is 14/24 pure, so in 250 g of 14-karat gold the amount of pure gold is

14/24 * 250 g

The total weight of the bracelet is 250 g.

Let x = the weight of 18-karat gold.

Then the weight of 14-karat gold needed is 250 - x.

weight of pure gold from 14-karat gold + weight of pure gold from 18-karat gold = weight of pure gold in 14-karat gold bracelet

0.5 * (250 - x) + 0.75x = 14/24 * 250

125 - 0.5x + 0.75x = 7/12 * 250

125 + 0.25x = 7/12 * 250

1500 + 3x = 1750

3x = 250

x = 250/3

x = 83.3

250 - x = 250 - 83.3 = 166.7

Answer: 83.3 g of 18-karat gold and 166.7 g of 12-karat gold
