C. 1,260 ways
D. 1,500 ways
Answer:
A
Step-by-step explanation: add 15+12+7
if im write can i get a brainliest? plss:>
The band director can create a trio in 1,260 different ways.
Hence, option C is correct.
Use the concept of permutations,
The formula for permutations is,
⇒ [tex]^{n}P_{r}[/tex] = n! / (n - r)!
Where n is the total number of items and r is the number of items we are selecting.
So in this case, we have,
⇒ n = 15 clarinet players
⇒ n = 12 flute players
⇒ n = 7 saxophone players
⇒ r = 1 clarinet player,
1 flute player, and 1 saxophone player
To find the number of ways we can create a trio with one player from each instrument, we need to calculate,
⇒ ([tex]^{15}P_{1}[/tex]) x ([tex]^{12}P_{1}[/tex]) x ([tex]^{7}P_{1}[/tex])
⇒ ([tex]^{15}P_{1}[/tex]) = 15! / (15 - 1)!
= 15! / 14!
= 15
This represents the number of ways we can choose one clarinet player out of 15.
([tex]^{12}P_{1}[/tex]) ) = 12! / (12 - 1)!
= 12! / 11!
= 12
This represents the number of ways we can choose one flute player out of 12.
[tex]^{7}P_{1}[/tex] = 7! / (7 - 1)!
= 7! / 6!
= 7
This represents the number of ways we can choose one saxophone player out of 7.
So the total number of ways we can create a trio consisting of one clarinet player, one flute player, and one saxophone player is,
⇒ 15 x 12 x 7 = 1,260
Therefore,
The band director can create a trio in 1,260 different ways.

Find the volume of a pyramid with a square base, where the side length of the base is 14.1 feet and the height of the pyramid is 13.1 feet. Round your answer to the nearest 10th of a cubic foot.
Answer:
= 868.1ft^3
Step-by-step explanation:
Volume of the square based pyramid = BH/3
B is the base area
H is the height of the pyramid
Base area = Length * Length
Base area = 14.1*14.1
BAse area = 198.81ft^2
Height = 13.1feet
Substitute
Volume = 198.81*13.1/3
Volume of the pyramid = 868.1ft^3
Hence the volume of a pyramid with the square base is 868.1ft^3
Answer: 868.1 ft^3

Complete the recursive formula of the arithmetic sequence -3, -1, 1, 3,...
b(1)= "answer"
b(n)=b(n-1)+ "answer"
Given:
The given arithmetic sequence is:
[tex]-3,-1,1,3,...[/tex]
To find:
The recursive formula of the given arithmetic sequence.
Solution:
We have,
[tex]-3,-1,1,3,...[/tex]
Here, the first term is -3. So, [tex]b(1)=-3[/tex].
The common difference is:
[tex]d=-1-(-3)[/tex]
[tex]d=-1+3[/tex]
[tex]d=2[/tex]
The recursive formula of an arithmetic sequence is:
[tex]b(n)=b(n-1)+d[/tex]
Where, d is the common difference.
Putting [tex]d=2[/tex], we get
[tex]b(n)=b(n-1)+2[/tex]
Therefore, the recursive formula of the given arithmetic sequence is [tex]b(n)=b(n-1)+2[/tex], where [tex]b(1)=-3[/tex].

Gavin is subdividing land into two plots, where one plot is in the shape of a square and the other plot is in the shape of a rectangle. The square plot of land has a side length of 6x³ feet, and the rectangular plot of land has a length of 3x⁵ feet and a width of 7x² feet. Use the properties of exponents to determine the expression that represents the area for each plot of land. Then analyze which plot of land has a larger area if x is 3.
The square plot of land has a larger area when x is 3.
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
To find the area of the square plot, we can use the formula for the area of a square: A = [tex]s^2,[/tex] where s is the length of a side of the square. In this case, the side length is 6x³ feet, so the area of the square plot is:
A = [tex](6x³)^2 = 36x^6[/tex]square feet
To find the area of the rectangular plot, we can use the formula for the area of a rectangle: A = lw, where l is the length of the rectangle and w is the width. In this case, the length is 3x⁵ feet and the width is 7x² feet, so the area of the rectangular plot is:
A = (3x⁵)(7x²) = 21x⁷ square feet
To analyse which plot of land has a larger area if x is 3, we can substitute x = 3 into the expressions for the areas of the plots:
Area of square plot[tex]= 36(3)^6[/tex] [tex]= 11664[/tex] square feet
Area of rectangular plot =[tex]21(3)^7 = 5103[/tex] square feet
Therefore, the square plot of land has a larger area when x is 3.

If y varies inversely with x and y = 8 when x = 10, then what is the constant of variation?
Answer:
Constant Variation = 80Step-by-step explanation:
Here,
Said that x and y vary inversely ,
So,
Then an increase in x causes corresponding decrease in y and vice-versa then to find the constant k will be:
xy = kHence,
Here y = 8 and x = 10
So their constant will be,
x × y = k
=> k = 8 × 10
=> k = 80
Therefore, the required constant is 80 (Ans)
