What are the answer options
Answer:
192.1%
Step-by-step explanation:
The formula for the amount of interest is ...
i = Prt . . . . . where i is the interest amount, P is the principal, r is the annual rate, and t is the number of years. (Here, we have a fraction of a year.)
Solving for the rate, we have ...
r = i/(Pt)
For "exact" interest, we use 365 days in the year. So, for a time of 19 days of 365, the interest rate is ...
r = $35/($350·19/365) ≈ 1.921 = 192.1%
Answer:
A is 100%
B is 50%
C is 33.333%
D is 50%
E is 200%
F is 66.666

Answer:
the surface area of the prism = <em>378</em> cm³
Step-by-step explanation:
Let S be the surface area of the prism
B be the base of the prism
h be the height of the prism
T be the lateral surface area of the prism
_______
Formula
S = 2B + T
_________
Let x = cost of one skirt
Let y = cost of one coat.
We need to construct a system of equations to help us solve this problem.
Lily: $452.62 = 6x + 5y
Sis: $289.36 = 3x + 5y.
Let's solve this by elimination. Multiply the second equation by -1
Lily: $452.62 = 6x + 5y
Sis: -$289.36 = -3x + -5y. Add the equations together.
$163.26 = 3x. Divide each side by 3.
$54.42 = x. Plug this into one of our original equations.
$452.62 = 6(54.42) + 5y. Multiply 6 by 54.42
$452.62 = 326.52 + 5y. Subtract 326.52 from each side.
$126.1 = 5y. Divide each side by 5
$25.22 = y.
One coat costs $25.22
