Answer:
the answer to the question is -1
Answer: the price of a bottle of water is $1.5
Step-by-step explanation:
Let x represent the price of one pretzel.
Let y represent the price of one bottle of water.
At the shopping mall, Joaquin bought 4 pretzels and a bottle of water for 11.50. It means that
4x + y = 11.5- - - - - - - - - -1
Kelly bought 3 pretzels and a bottle of water for 9.00. It means that
3x + y = 9- - - - - - - - - - - - 2
Subtracting equation 2 from equation 1, it becomes
x = 2.5
Substituting x = 2.5 into equation 1, it becomes
4 × 2.5 + y = 11.5
10 + y = 11.5
y = 11.5 - 10
y = 1.5
Mid segment = (1/2)base
12.5 = (1/2)* base
Multiply both sides by 2
25 = base
Letter b
Answer:
The doubling time of this investment would be 9.9 years.
Step-by-step explanation:
The appropriate equation for this compound interest is
A = Pe^(rt), where P is the principal, r is the interest rate as a decimal fraction, and t is the elapsed time in years.
If P doubles, then A = 2P
Thus, 2P = Pe^(0.07t)
Dividing both sides by P results in 2 = e^(0.07t)
Take the natural log of both sides: ln 2 = 0.07t.
Then t = elapsed time = ln 2
--------- = 0.69315/0.07 = 9.9
0.07
The doubling time of this investment would be 9.9 years.
