Answer:
$160
Step-by-step explanation:
Part A-
Step 1: 6(2k+5) - 20
Step 2: 6(2k) + 6(5) - 20
Step 3: 12k + 30 - 20
<h2><u>
12k + 10</u></h2><h2><u>
</u></h2><h3>Part B-</h3><h3>12(12.50) + 10</h3><h3>150 + 10</h3><h2><u>$160</u></h2>
Answer:
Step-by-step explanation:
the answer is
$194 (start) / <u>100 (100%)</u> = $1.94 (1%)
$1.94 * 7 = $13.58 (7%)
$13.58 * <u>13 (13 years)</u> <em>= $176.54 </em>
$194 (start) + <u>$176.54 (interest)</u> <em>= $370.54</em>
Answer:
37.6 degrees
Step-by-step explanation:
tan x = 48.6 / 63.1 where x = angle of elevation
tan x = 0.770206
x = 37.6 degrees
Answer:
5 inches
Step-by-step explanation:
The volume of a cone formula is V = (1/3)(base)(height). Thus, 3V =(base)(ht).
We want to calculate the height of the cone. Divide both sides of
3V =(base)(ht) by (base), obtaining 3V/(base) = ht.
Substituting 12 in^3 for V, and 2.25pi for (base), we get:
12 in^3
------------ = 5.33 in, or, to the nearest inch, 5 inches.
2.25 pi
Note: The diameter of the cone is 3 inches. The area of the base is pi*r^2, so we must divide d = 3 inches by 2 to obtain the radius: 1.5 in. Then r^2 = 2.25 in^2.
