Answer:
-4
Step-by-step explanation:
bc it is
.......................
Area=3.14(r)^2
radius is half of diameter
3.14(9.5)^2=283.385
rounded is 283.39
We let x as the cost of one ounce of Sumatra and y as the cost of one ounce of Celebes Kalossi. For mixture 1, we have 12x + 4y = 32 and for mixture b, we have 4x + 12y = 40
First, Multiply eq. 1 by 4
4(12x + 4y = 32)4 ⇒ 36x + 12y = 96
We now have
(36x + 12y = 96) – (4x + 12y = 40)
<span>X = 1.75 ⇒ cost of one ounce of Sumatra
</span>
Substitute x to either equation to get the value of y
12(1.75) + 4y = 324
y = 32-21
4y = 11
Y = 2.75 ⇒ cost of one ounce of Celebes Kalossi

Answer: 45
Step-by-step explanation:
By the tangent secant theorem we have AB^2 = BD(BD + CD)
So...
14^2 = 4(CD +4)
196 = 4CD + 16
4CD = 180
CD = 45
