Three research departments have 8 ,10 , and 7 members, respectively. Each department is to select a delegate and an alternate to represent the department at a conference. In how many ways can this be done?
Answers
We can conclude that exists 211680 ways.
How many ways can this be done?We know that the three research department is have 8, 10, and 7 members.
We choose a delegate and an alternate to represent the department.
First case: department have 8 members.
So, for a delegate, we have 8 options, and for a alternate 7, so a total of
\(8 \times 7 = 56 \ \text{options}\)
Second case: department have 10 members.
So, for a delegate, we have 10 options, and for a alternate 9, so a total of
\(10\times 9 =90 \ \text{options}\)
Third case: department have 7 members.
So, for a delegate, we have 7 options, and for a alternate 6, so a total of
\(7\times6 = 42 \ \text{options}\)
Therefore, we get:
\(56 \times 90 \times 42 = \bold{211680}\)
Hence, we conclude that exists 211680 ways.
For a similar problem about this, please click the link below:
https://brainly.com/question/30958797
For the first department with 8 members, there are 8 choices for selecting a delegate. After choosing a delegate, there remain 7 members, so there are 7 choices for selecting an alternate. Therefore, there are 8 × 7 = 56 ways to select a delegate and an alternate from the first department.
Similarly, for the second department with 10 members, there are 10 choices for selecting a delegate and 9 choices for selecting an alternate. Hence, there are 10 × 9 = 90 ways to select a delegate and an alternate from the second department.
For the third department with 7 members, there are 7 choices for selecting a delegate and 6 choices for selecting an alternate. Thus, there are 7 × 6 = 42 ways to select a delegate and an alternate from the third department.
To find the total number of ways to select delegates and alternates from all three departments, we multiply the number of choices for each department together:
56 × 90 × 42 = 211,680.
Therefore, there are 211,680 ways to select a delegate and an alternate from each department.

The two top NBA players played a basketball game against the RSM team. Together the NBA players made 85 baskets, scoring one point for free throws and two or three points for field goals. They scored a total of 184 points during the game. If they made 22 free throws, how many three-point field goals did they make?
Answers
Answer: 36 three-point field goals
Step-by-step explanation:
To solve this problem, set up a system of equations. Let's call the number of one-pointers \(w\), the number of two-pointers \(x\), and the number of three-pointers \(y\). We are trying to find \(y\) here. We also know that \(w+x+y=85\), because that is the total amount of baskets, and also that \(w+2x+3y=184\), which is the total amount of points. We know that there were 22 free throws, so that means we can take away 22 baskets from the first equation, and also 22 points from the second equation. Now the equations are \(x+y=63\) and\(2x+3y=162\). Solving the equations using our knowledge of systems of equations, you get that \(y=36\). So, 36 is the answer. Let me know if anything was unclear, and I hope this helped.
The number of two-point and three-point field goals they made is 27 and 36, respectively.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the number of two points basket be represented by x and the number of three points basket be represented by y.
Now, since the total number of basket is 85, out of which 22 were free throw. Thu, we can write the equation as,
22 + x + y = 85
Solving the equation for x,
x = 85 - 22 - y
x = 63 - y
Further given that the total point made is 184. Therefore, the total number of score can be written as,
22 + 2x + 3y = 184
22 + 2(63 - y) + 3y = 184
22 + 126 - 2y + 3y = 184
y = 36
Substitute the value of y in the first equation,
22 + x + y = 85
x = 85 - 22 - 36
x = 27
Hence, the number of two-point and three-point field goals they made is 27 and 36, respectively.

Answers
Answer:
5.906 x 10^9
Step-by-step explanation:
(6.25 x 10^9) − (3.44 x 10^8).
step 1: make the exponents have common value
Move decimal point of 3.44 to the left once and add 1 to it's exponents.
that is 3.44 x10^8 becomes 0.344 x 10^9
= 6.25 x 10^9 - 3.44 x 10^8
= 6.25 x 10^9 - 0.344 x 10^9
step 2: bring out the common factor 10^9 since the exponents are the same.
Also, subtract the decimal numbers.
= (6.25 -0.344) 10^9
6.25 - 0.344 = 5.906
Therefore, the result is 5.906 x 10^9.

Mrs. Jones wants to paint the back wall of her classroom light blue. If the dimensions of the wall is 20 feet by 12 feet, how much paint will she need to paint her classroom wall? Round to the nearest tenth if necessary.
Answers
Answer:
The total area of the back classroom wall is (20ft x 12ft) = 240ft²
The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².
Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.
Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

Answer:(number)=-5
Step-by-step explanation:
You can use simple logic in order to solve this equation.
An equation that has infinitely many solutions will have the same exact numbers on both sides
Example: 3x = 3x, it has infinite solutions because no matter what number you put, the equation will always be true
The solution for this equation is -5 because when -5x-19=-5x-19, no matter what number you put as a solution, it will be true.

It took a plane 2 hours to fly from Dallas to New York with the headwind and 1.5 hours to return with the tailwind. If the speed of the wind was 30 mph, how far apart are the two cities?
Answers
Answer:
The distance between the two cities is 360 miles.
Step-by-step explanation:
Let a equal the airspeed of the plane in still air; and d be the distance between the two cities. Then:
d/a+30=1.5
d=1.5a+45
and
d/a-30=2
d=2a-60
So
2a-60=1.5a+45
.5a=105
a=210
d/210-30=2
d=360
The distance between the two cities is 360 miles.

Jada’s babysitter is times Jada’s current age. In 5 years, Jada will be her
babysitter’s current age.
How many years old is Jada now?
Answers
Answer:
5 years old.
Step-by-step explanation:
Let's call Jada's current age "J" and the babysitter's current age "B".
From the information given, we know:
B = J (Jada's babysitter is J times Jada's current age)
J + 5 = B (In 5 years, Jada will be her babysitter's current age)
By substituting the first equation into the second equation:
J + 5 = J
5 = J
Therefore, Jada is currently 5 years old.
1. Stacey earns $15 each week plus $.50 for each customer on her paper route. She
wants to earn at least $25 each week. What equation can she use to find x, the
number of customers she needs to make exactly $25?
A x + 15 = 25
B 0.50x + 15 = 25
C 2x + 15 = 25
D 50x + 15 = 25
Answers
Explanation: the $0.50 is multiplied by the number of customers(“plus $.50 for each customer on her paper route”). So, it can’t be A, because the $0.50 is not in the equation. It can’t be c, because there should not be $2 for the number of customers(x). It can’t be D either because it’s 0.50, not 50. So, you’re left with B.
