69 + 2h = 84 - 3h
2h + 3h = 84 - 69
5h = 15
h = 15/5
h = 3 <=== the temps will be the same in 3 hrs
69 + 2(3) = 69 + 6 = 75
84 - 3(3) = 84 - 9 = 75
and the temps will both be 75 F <==
Answer:
its 10.5
Step-by-step explanation:
i did the math 1.5 if you move the decimal
It asked for width to length, so it is really important to put the width on top and the length on bottom.

Answer: the interest rate is 6%
Step-by-step explanation:
The formula for continuously compounded interest is
A = P x e (r x t)
Where
A represents the future value of the investment after t years.
P represents the present value or initial amount invested
r represents the interest rate
t represents the time in years for which the investment was made.
e is the mathematical constant approximated as 2.7183.
From the information given,
A = $4482
P = 1000
t = 25 years
Therefore,
4482 = 1000 x 2.7183^(r x 25)
4482/1000 = 2.7183^25r
4.482 = 2.7183^25r
Taking ln of both sides, it becomes
Ln 4.482 = 25rLn2.7183
1.5 = 25r
r = 1.5/25 = 0.06
r = 0.06 × 100 = 6%
