step 1. a 30-60-90. triangle has sides 1- sqr3-2 where sqr is the square root.
step 2. x = 6/sqr3 = 2sqr3. y = 12/sqr3 = 4sqr3.
A = 1/4 * (pi) * d^2
A = 1/4 * (pi) * 8^2
A = 1/4 * (pi) * 64
A = 1/4(64) * (pi)
A = 64/4 * (pi)
A = 16 (pi) in^2
Answer:
Total Price with Tax: $ 605.72
Step-by-step explanation:
We can write an equation for the total cost of the bicycle as:
C=p+(t×p)
Where:
C is the total cost we are trying to calculate.
p is the list price - $556.98
t is the tax rate - 8.75%. "%" means "out of 100" or "per 100", Therefore 8.75% can be written as 8.75
.
Substituting and solving for C gives:
C = $556.98(
×$556.98)
C = $556.98+$48.74
C = $605.72
