Answer:
2.174 hours
Step-by-step explanation:
Let the number of hours be represented as:
x
The price of Stock A at 9 A.M. was $12.79 Since then, the price has been increasing at the rate of $0.11 each hour.
$12.79 + $0.11 × x
12.79 + 0.11x
At noon the price of Stock B was $13.29 It begins to decrease at the rate of $0.12 each hour.
$13.29 - $0.12× x
13.29 - 0.12x
Equating both equations together
Stock A = Stock B
12.79 + 0.11x = 13.29 - 0.12x
Collecting like terms
0.11x + 0.12x = 13.29 - 12.79
0.23x = 0.5
x = 0.5/0.23
x = 2.1739130435 hours
x = Approximately = 2.174 hours
If the two rates continue, the number of hours that the prices of the two stocks will be the same is 2.174 hours
Answer: 54.33%

14 carat gold contains 58.33% gold and 4% silver (since we are using the lowest percentage).
58.33% - 4% = 54.33%

We know, Circumference of a Circle = 2πr
In mathematical form, You can write it as:
2πr₁ = 3(2πr₂)
2π(12) = 6πr₂
24π = 6πr₂
r₂ = 4 m
In short, Your Answer would be: 4 meter
Hope this helps!
