Answer:
the cost of making each paperweight = $0.81
Step-by-step explanation:
First let us calculate the selling price for each paperweight as follows:
total amount gotten = $230.85
number of paperweights = 95
∴ 95 paperweights = $230.85
∴ 1 paperweight = 230.85 ÷ 95 = $2.43
selling price of 1 paperweight = $2.43
Next, let the cost of making 1 paperweight be 'x'
selling price of paperweight = cost of making + profit gotten
The cost of making the paper weight (x) plus the profit made on the paper weight (2x) equals the selling price of each paper weight.
x + 2x = 2.43 (the profit the club makes is two times as much as the cost to make each paperweight)
∴ 3x = 2.43
x = 2.43 ÷ 3 = 0.81
Therefore, the cost of making each paperweight = $0.81
Answer:
x=0
Step-by-step explanation:
in the quadratic formula to only have one solution
for 
so we have
if we insert in the formula we have
since a≠0
The answer is <span>amplitude = 2 feet; period = 24 hours; midline: y = 3
x1 - the lowest point
x2 - the highest point
x1 = 1 ft
x2 = 5 ft
t1 = 0
t2 = 24
The amplitude is: (x2 - x1)/2 = (5 - 1)/2 = 4/2 = 2 ft
The period is: t2 - t1 = 24 - 0 = 24 h
The midline is: (x1 + x2)/2 = (5 + 1)/2 = 6/2 = 3 ft</span>
