Given:
Violinists : Cellists = 7:3.
Number of violinists in the school orchestra = 21
To find:
The combined number of cellists and violinists.
Solution:
Let the number of violinists and cellists in the school orchestra are 7x and 3x respectively.
Then, combined number of cellists and violinists is
...(i)
Number of violinists in the school orchestra = 21
Divide both sides by 7.
Now, the combined number of cellists and violinists is
[Using (i)]
Therefore, the combined number of cellists and violinists is 30.
Since the equation is:
<span>P(x)=-5x^2+40x-300
Solving the equation by using the calculator, the values for x are:
x = 4.72

Answer:
105 square feet
Step-by-step explanation:
First of all, find the area of the rectangle (length x width). 7*12 = 84. Now, find the area of the triangle [(base x height)/2]. 6*7 = 42. 42/2 = 21.
Add both of these areas together: 84 + 21 = 105. The area is 105 square feet.
