There are 12,600 ways to choose 10 balls satisfying the given conditions of at least one red ball, at least two blue balls, and at least three green balls.
To calculate the number of ways to select the balls, we can use the concept of combinations.
Let's break down the selection criteria:
At least one red ball: This means we can select 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 red balls.
At least two blue balls: This means we can select 2, 3, 4, 5, 6, 7, 8, 9, or 10 blue balls.
At least three green balls: This means we can select 3, 4, 5, 6, 7, 8, 9, or 10 green balls.
To find the total number of ways to select the balls, we need to consider all possible combinations of selecting the specified number of balls from each color category. We can calculate this by summing up the combinations for each case:
Number of ways = C(1, 10) × C(2, 9) × C(3, 7) = 10 × 36 × 35 = 12,600.
Therefore, there are 12,600 ways to select 10 balls satisfying the given conditions of at least one red ball, at least two blue balls, and at least three green balls.

The optimal values of x and y to maximize the profit are 10 and 10, respectively, and the maximum profit is $200.
Let X and Y represent the number of units of product A and B that we want to produce. We want to maximize the profit, so our objective function is:
Profit = 10x + 15y
The constraints are:
X + Y ≤ 20
2X + Y ≤ 30
X ≥ 0, Y ≥ 0
To find the optimal values of x and y, we must first solve the system of equations. By subtracting the first equation from the second equation, we get:
X = 10
Substituting this value into the first equation, we get:
Y = 10
Now that we have found the values of x and y, we can plug them into the objective function to find the maximum profit:
Profit = 10(10) + 15(10) = 200
Therefore, the optimal values of x and y to maximize the profit are 10 and 10, respectively, and the maximum profit is $200.

Difference in the weekly earnings of Dana and Monique is $127.5.
What is Multiplication?Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Dana :
Number of days Dana grooms dogs = 4 days a week
Number of dogs Dana grooms in a day = 15 dogs
Number of dogs Dana grooms in a week = 15 × 4 = 60 dogs
Earning of Dana per dog = $12.75
Earnings of Dana in a week = 60 × $12.75 = $765
Monique :
Number of days Monique grooms dogs = 5 days a week
Number of dogs Monique grooms in a day = 10 dogs
Number of dogs Monique grooms in a week = 10 × 5 = 50 dogs
Earning of Monique per dog = $12.75
Earnings of Monique in a week = 50 × $12.75 = $637.5

So far, Leo has put together 40% of his 500-piece puzzle. How many puzzle pieces has Leo put together?
200
Step-by-step explanation:Portions of quantities can be represented as percentages and decimals, which can help solve different types of questions.
Multiplying Decimals
To find any percent of a quantity, you can multiply the quantity by the percentage as a decimal. We can convert percentages to decimals easily. By moving the decimal point 2 places to the left, we can change 40% into a decimal. So, 40% is equal to 0.4. Now, multiply this by 500.
500 * 0.4 = 200So, Leo has put together 200 pieces.
Multiples of 10
Since 40% is a multiple of 10, we can solve using another method. It is easy to find 10% of any quantity, just move the decimal point 1 place to the left. So, 10% of 500 is 50.
Then, since 40 is 4 times 10, we can say that 40% of 500 is 4 times 10% of 500.
50 * 4 = 200This proves that Leo has done 200 pieces.

To determine the limit of f(x) as x approaches -7, we need to analyze the behavior of the function as x gets closer and closer to -7.
Since f(x) is defined differently for x < 7 and x >=7, we need to look at both cases separately.
For x < 7, f(x) = -3x + 0
For x >= 7, f(x) = 5x + 1
If we substitute x = -7 into the first equation, we get f(-7) = -3(-7) + 0 = 21
If we substitute x = -7 into the second equation, we get f(-7) = 5(-7) + 1 = -36
We can see that the function is defined differently for x < 7 and x >=7, and it does not have the same value when x = -7.
Therefore, the limit of f(x) as x approaches -7 does not exist (DNE).

What are the prime multiples of 4?
Answer:
Step-by-step explanation:
The prime multiples of 4 are 2*2 or 2^2.
Camille is sixty-six inches tall. This is twenty inches less than two times Mindy's height. How tall is Mindy ?
Let's call Mindy's height "M". According to the problem, we know that:
Camille's height = 66 inches
Camille's height = 2 * Mindy's height - 20 inches
We can substitute the first equation into the second equation to solve for Mindy's height:
66 inches = 2 * M - 20 inches
We can add 20 inches to both sides of the equation to get:
66 inches + 20 inches = 2 * M
This gives us:
86 inches = 2 * M
To find Mindy's height, we can divide both sides of the equation by 2:
M = 86 inches / 2
So Mindy is 43 inches tall.
Answer:
Mindy is 46 inches
Step-by-step explanation:
Let m = Mindy's height
66 = 2m - 20 Add 20 to both sides
66 + 20 = 2m - 20 + 20
86 = 2m Divide both sides by 2
