Answer: B. 479,001,600
Step-by-step explanation:
We know that the number of possible combination objects from a set where order matters is given by using permutations.
Given: The number of basketball players = 12
By using permutations, the number of ways the basketball players can be listed is given by :-
Answer:
B. 479001600
Step-by-step explanation:
We are asked to find the number of ways can 12 basketball players be listed in a program.
We will use permutations to solve our given problem.
There are 12 ways to choose 1st player for the team.
Since 1 player is already chosen, so we can choose 2nd player in 11 ways. Similarly we can choose 3rd player in 10 ways.
Therefore, in 479001600 ways can be 12 basketball players be listed in a program and option B is the correct choice.
Answer:
Step-by-step explanation:
Perimeter of rectangle given = 26 cm
And measure of a side of the rectangle = 5 cm
Since perimeter of a rectangle = 2(length + width)
By replacing the values of perimeter and length in the formula
26 = 2(5 + width)
5 + width =
width = 13 - 5 = 8 cm
Now we can draw a rectangle of length = 5 cm and width = 8 cm
The number of the outcomes will be 10 if there is not any tie.
The arrangement of the different things or numbers in a number of ways is called the combination.
Here we need to find the outcomes of the winning of 10 people the combination will be:-
Hence the number of the outcomes will be 10 if there is not any tie.

a. Write an inverse variation model for the relationship between the area and depth for one load of gravel.
b. A designer plans a playground with gravel 6 in. deep over the entire play area. If the play area is a rectangle 40 ft. wide and 24 ft long, how many loads of gravel will be needed? (4 points)
I understand everything else but this question.
Answer:
A. y=
B. z= 2
Step-by-step explanation:
A.
The format for the inverse variation formula is y =
This is a bit different compared to the format of directly variation formula y= kx
In this case, one load of gravel have volume. The area is inversely proportional with depth, so formula for the volume is Area x Depth (V= A x D). The inverse variation formula will be: A= V/D
If the number of loads=z, each load is , area = y and depth = x , then the model will be:
y=
y=
B.
The play area is a rectangle 40 ft wide and 24 ft long, then the area will be: area = 40ft * 24ft= 960
We have area(y= 960 ) and depth(x= 6 in- 0.5 ft) , now we can find out the number of loads needed(z) by using the equation.
y=
960 =
= 960
z= = 2
