A. $0.08 per ounce
Price divided by ounces gives you the unit price.
$9.60/120 ounces = $0.08/ounce
So, the slope is 2 for each of the points. Now, you plug it into y=mx+bSo, you get, y=2x+b
To find b, you choose any pair of x and y values.-5=-22+bb=17

Second Question: 12.56
Step-by-step explanation:
Answer:
The height of the tree = 25 feet
Step-by-step explanation:
From the given diagram : EF = 5 feet, FA = 8 feet, CA = 40 feet
∠AFE = 90° and ∠ACB = 90°
To find : CB, the height of the tree.
Solution : In ΔAEF and ΔAB C
∠AFE = ∠ACB = 90°
∠A is common angle.
So, By AA postulate of similarity of triangle, ΔAEF ~ ΔABC
Now, sides of similar triangles are proportional to each other
Hence, The height of the tree = 25 feet
Answer:
The radius of the given circle ( r ) = 2√2
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the center of the circle C = ( -2,1)
Given a point on the circle P = (0,3)
The distance between the center and point is called the radius of the circle
CP = radius of the circle
<u><em>Step(ii):-</em></u>
CP = √8 =
<u><em>Final answer:-</em></u>
The radius of the given circle ( r ) = 2√2
