question: An investment of $100 is now valued at $149.18 the interest rate is 8% per year, compounded continuously about how long has the money been invested
Answer:
5.2 years
Step-by-step explanation:
Applying
A = P(1+R/100)ⁿ.......................... Equation 1
Where A = amount, P = principle, R = rate, n = time.
From the question,
Given: A = $149.18, P = $100, R = 8%
Substitute these values into equation 1 and solve for n
149.18 = 100(1+8/100)ⁿ
149.18/100 = (1+8/100)ⁿ
1.4918 = (1+0.08)ⁿ
1.4918 = (1.08)ⁿ
Taking the Logarithm of both side
Log(1.4918) = Log(1.08)ⁿ
Log(1.4918) = nLog(1.08)
n = Log(1.4918)/Log(1.08)
n = 0.1737/0.0334
n = 5.2 years.
Answer:
a. yes
Step-by-step explanation:
If 16 - u = -4 and u = 20:
16 - 20 = -4
The equaton is correct, therefore the given value of u is the solution to the equation.
L = 15m = 1500cm
b= 30cm
h= 4m= 400cm
So, total volume of the wall= l×b×h
= 1500×30×400= 1,80,00,000 cm^3
Now, volume of one brick= 22×12.5×7.5= 2062.5 cm^3
Volume of wall containing only bricks= total volume of the wall - volume of wall containing mortar
= 1,80,00,000 - (1,80,00,000 × 1/12)
= 1,65,00,000 cm^3
So, no. of bricks = volume of wall containing bricks ÷ volume of one brick
= 1,65,00,000 ÷ 2062.5
= 8000 bricks.
8 fluid oz=1 cup
2 cup=1 pint
so
16 fluid oz=1pint
so just divide 455 by 16 or estimate by rounding 16 to 15 and 455 to 450
we know that 45/15=3 so the andwer is 450/15=30
about 30 pints
