Answer:
In this case, the equation that models the value of an initial investment of P dollars in t years at an annual interest rate of r is given by A = Pert.
Step-by-step explanation:
Answer: 16 years
Step-by-step explanation:
Let's Bo's age be represented by x.
Since Bo' sister Anna is 3/4 his age minus 1 year and she is 11 years old, this can be formed into an equation as:
(3/4 × x) - 1 = 11
3/4x - 1 = 11
3/4x = 11 + 1
3/4x = 12
Multiply both side by 4/3
x = 12 × 4/3
x = 16
Bo's age is 16 years
For A. You didn't gave the picture of the problem but I will attach it later with the picture of B. We are looking for the perimeter, the answer is <span>2 + 12 + 2 + 3 + 5 + 3 + 2 + 9 + 7 + 3 = 48 cm.
For B. The radius is 4 in. So the formula is given, 2pi r = 2(pi)(4 in) = 25.1327412 in is the circumference of a circle which only signifies three fourths.</span>
