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:
x = 0
y = 3
Explanation:
There are multiple ways to solve systems of equations. For this particular example, you can simply set them equal to each other because they are both equal to y and y = y, so therefore the equations equal each other.
so,
2x + 3 = -3x + 3
then solve for x!
add 3x to both sides: 5x + 3 = 3
subtract 3 from both sides: 5x = 0
divide by 5: x = 0
then to find y, plug the 0 back into either equation.
y = 2(0) + 3
y = 3
so, x = 0 and y = 3

Answer: yes
Step-by-step explanation:
100/1200= x/100
cross multiply
(1200 * x)= (100 * 100)
1200x= 10000
divide both sides by 1200
x= 8.333% winning chance
LOSING CHANCE
100% - 8.333%= 91.667%
RATIO OF WINNING TO LOSING
100 tickets= winning chance
1200 total - 100= 1100 losing chance
100:1100
simplify by 100
1:11 odds of winning to losing
ANSWER: The chance of winning is 8.333% and the chance of losing is 91.667% or 1:11.
Hope this helps! :)
