The length and width for a maximum area is 10 popsicle by 10 popsicle.

An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.

Let x represent the length to Craig's house and y represent the width. Hence:

2(x + y) = 40

x + y = 20

y = 20 - x      (1)

Area (A) = xy = x(20 - x)

A = 20x - x²

The maximum area is at A' = 0, hence:

A' = 20 - 2x

20 - 2x = 0

x = 10

y = 20 - (10) = 10

Answer:

he correct answer is c. vD = -7 vs = 5.

The Doppler shift equation is:

f = f' (v - vD) / (v - vS)

Where:

f is the frequency detected

f' is the frequency emitted

v is the speed of sound

vD is the velocity of the detector

vs is the velocity of the source

In this case, the source is traveling at 5 m/s away from the detector, the detector is traveling at 7 m/s toward the source, and there is a 3 m/s wind blowing from the source toward the detector.

The velocity of the detector is negative because it is moving towards the source. The velocity of the source is positive because it is moving away from the detector.

Therefore, the values that should be substituted into the Doppler shift equation are:

vD = -7

vs = 5

Step-by-step explanation:

The number of ways the ribbons can be awarded in a race with "x" runners is x * (x-1).

The number of ways the ribbons can be awarded depends on the total number of runners participating in the 100-meter dash.

If there are "x" runners participating, the winner can be any one of the x runners, and the second-place runner can be any one of the remaining (x-1) runners.

Therefore, the number of ways the ribbons can be awarded is equal to the number of possible choices for the winner multiplied by the number of possible choices for the second-place runner.

Mathematically, this can be expressed as:

Number of Ways = x * (x-1)

For example, if there are 5 runners in the race, there are 5 ways to choose the winner. After selecting the winner, there are 4 remaining runners from which we can choose the second-place runner. So, in this case, the number of ways the ribbons can be awarded is:

Number of Ways = 5 * 4 = 20

In general, the number of ways the ribbons can be awarded in a race with "x" runners is x * (x-1).

Answer:

C. 7x + 45

Step-by-step explanation:

To start answering this question, let's first distribute the 6 * ( x + 7 ) so that we can add like terms to simplify.

So let's multiply the 6 out to the ( x + 7 ) to get ( 6x + 42 ).

Now the complete expression reads: 6x + 42 + ( x + 3 )

With this, we can add all the like terms( 6x and x, and 42 and 3) together.

So we end up with 6x + x + 42 + 3 = 7x + 45

So the correct answer is C. 7x + 45

The given information consists of a series of equations involving variables b1, b3, and b4, as well as the constant values 8, 9, and 10. The objective is to calculate the value of b3.

To find the value of b3, we need to analyze the given equations and use algebraic techniques to solve for the unknown variable.
From the equations given, we can observe that b1 = 10, b4 = 9, and 62 = 8. These values provide fixed points of reference.
Next, we examine the equations involving b3. We have two equations: b3 - a = 15 and b3 - b = 10. However, there is no information provided about the values of a and b. Without additional information or constraints, we cannot determine the specific value of b3.
It is important to note that the solution to the problem depends on having all the necessary information or additional equations that can be used to solve for the unknowns. In this case, the lack of information about the values of a and b prevents us from calculating the exact value of b3.

The sum of the first six counting numbers is 21 and the sum of the first six two counting numbers is 64. The difference between these two sums is 43. Therefore,value of n is equal to 6.

The sum of the first n counting numbers is given by the formula n(n+1)/2. The sum of the first n two counting numbers is given by the formula 2n(n+1). Subtracting these two equations, we get 2n(n+1) - n(n+1)/2 = 43. Solving this equation for n, we get 2n2 + 2n - 43 = 0. Factoring this equation, we get (2n + 7)(n - 6) = 0. Since both of these factors must equal zero, we get n = 6.

2n(n+1) - n(n+1)/2 = 43

Is 6/5 irrational? No, because it is a fraction.

Is π irrational? Yes, because it can't be written as a fraction as its digits continue infinitely without repetition.

Is 11/4 irrational? No, because it is a fraction.

Is 8.25635... irrational? Yes, because the ellipsis shows the digits continue infinitely without repetition, otherwise there would be a bar over the digits to show repetition

Is -7 irrational? No, because it can be written as a fraction (ex. -7/1, -14/2, etc.)

Is 6.31(bar) irrational? No, because the bar shows that the digits 3 and 1 repeat.

Therefore, only cards C and E are irrational.

What is the absolute value function?

The absolute value function is defined by:

|x| = x, x >= 0.

|x| = -x, x < 0.

The absolute value function measures the distance of a point x to the origin, that is, the distance to x = 0. From this, we get that |x| = a can mean either that:

x = a, or;

x = -a.

In this problem, the equation is given by:

Hence:

0.2|x - 4| = 9

|x - 4| = 45

The first possible solution is:

x - 4 = 45

x = 49.

The second possible solution is:

-x + 4 = 45

-x = 41

x = -41.
