Answer:
(16 + 8√3) in²
Step-by-step explanation:
The ratio of side dimensions for a 30°-60°-90° triangle are 1 : √3 : 2. If we call the horizontal dimension of the triangle its base, then its height (vertical dimension) will be √3×4 in. Of course the area of the triangle is ...
... A = (1/2)bh = (1/2)(4 in)(4√3 in) = 8√3 in²
The total sod area is the sum of the square area (16 in²) and the triangle area, so is ...
... area to cover = (16 +8√3) in²

<em>Comment on problem dimensions</em>
The area involved here is not much larger than the size of your hand. It would make more sense for the dimensions to be in feet or yards or meters, rather than inches.
Answer:
<h2>Table 2 is correct, you have it wrong</h2>
Step-by-step explanation:
The way we determine if ratios are equivalent is by a proportion. It also helps to know that a foot is 12 inches, so you have the wrong answer. The correct answer is table 2. The way we solve is by dividing the number of inches by 12 to see if we get the number of feet specified on the table.
24/12 = 2
60/12 = 5
72/12 = 6
84/12 = 7
All of these match up to their respective foot measurements.
Answer:
21 3/4
Step-by-step explanation:
Answer:
21.16
Step-by-step explanation:
First find the tax
16.40 * 9%
16.40 *.09 = 1.476 = 1.48
Then we need to find the tip
16.40 *20%
16.40 *.20 = 3.28
The total is the bill plus tax plus tip
16.40 + 1.48 + 3.28
21.16
