Answer:
$110 and $30
Step-by-step explanation:
To solve this, we need to know the total share which is,
![4 + 11 + 3 = 18](https://tex.z-dn.net/?f=4%20%2B%2011%20%2B%203%20%3D%2018)
Then, you need to know the fraction of the share over the total, such that
![x = \frac{4}{18}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B4%7D%7B18%7D%20)
![y = \frac{11}{18}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B11%7D%7B18%7D%20)
![z = \frac{3}{18}](https://tex.z-dn.net/?f=z%20%3D%20%20%5Cfrac%7B3%7D%7B18%7D%20)
So if to find how much that'll be of the $180 for the largest and smallest share,
Largest:
![\frac{11}{18} \times 180 = 110](https://tex.z-dn.net/?f=%20%5Cfrac%7B11%7D%7B18%7D%20%20%5Ctimes%20180%20%3D%20110)
Smallest:
![\frac{3}{18} \times 180 = 30](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B18%7D%20%20%5Ctimes%20180%20%3D%2030)
The proportion would be 1/3 and x/9. Cross multiplication creates 3x=9. Divide both sided by three, and there are 3 trombones in the orchestra.
Hey there,
Okay so for inverse equations I use the method in which you switch the variables and solve for y.
So the equation y = 100 - x would look like:
Now we solve for y in this equation:
Since the y is negative and we are solving for a positive we divide by -1 on both sides:
So the inverse of y = 100 - x would have to be -x + 100 = y.
Hope I helped,

Answer:
volume = (l x w x h)/3
12 = (3 x 2 x h)/3
36 = 6 h
h = 36 / 6 = <u>6 cm</u>

Answer: The area of the region covered with small rocks is 49.76 ft²
Step-by-step explanation:
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
The radius of the garden is 4 ft
Therefore,
Area of garden = 3.14 × 4² = 50.24ft²
The length of each side of the square is 10ft.
Area of square = 10² = 100ft²
The area of the region covered with small rocks = Area of the square - area of the circular garden. It becomes
100 - 50.24 = 49.76 ft²
