Answer:
$204 OR $210 (*READ BELOW)
Step-by-step explanation:
1. Find the perimeter.
Assume that it is a rectangle, so P = 2L + 2W P = 2(4.5) + 2(2.3) P = 9 + 4.6 P = 13.6 ft 2. Find the cost of the frame (C).
C = 15x, where x is the amount of feet of frame In this case, x = P = 13.6 C = 15(13.6) C = 204 Therefore, it will cost $204 for a frame for this specific mirror.
<u>HOWEVER </u>: sometimes your teacher will be specific and will say that they ONLY sell the frame BY THE FOOT so in this case, you'd have to round up the perimeter to 14 ft. So, C = 15(14), so the cost would end up being $210 instead.

Answer:
x^2 + (y+1)^2 = 10^2
Step-by-step explanation:
Centre (p,q) = (0, -1)
radius, r = 10
General Equation of a circle
(x-p)^2 + (y-q)^2 = r^2
(x-0)^2 + (y- -1)^2 = 10^2
x^2 + (y+1)^2 = 10^2
Answer:
.8
Step-by-step explanation:
5 red marbles, 2 Green marbles and 3 black marbles = 10 marbles
P (red or black) = number of red or black/ total
= (5+3)/10
=8/10
decimal form = .8
