Step-by-step explanation:

To rewrite the formula for diameter (d) in terms of the area (A) of the circle, you can use the following sequence:

1. A = [tex]pi * (d/2)^2[/tex]

2. [tex]d^2[/tex] = (2A)/pi

3. d = [tex]sqrt((2A)/pi)[/tex]

The question requires arranging the given equations to express the diameter of the circle in terms of its area. Let's proceed step by step:

Start with the formula for the area of a circle: A = pi * r^2, where 'r' is the radius of the circle.

Recall the relationship between diameter and radius: d = 2 * r.

Substitute radius 'r' with diameter 'd' in the area formula: This results in A = [tex]pi * (d/2)^2[/tex].

Solve this equation for diameter 'd': You'll get d = [tex]sqrt((4 * A)/pi)[/tex].

Answer:8

Step-by-step explanation:

Divide the amount of money she has by the amount the bottles cost. And you will get 8! Check your answer by multiplying 8 by 22.87

Final answer:

Nidhi can buy a maximum of 8 bottles of wine with her $185 budget, as each bottle costs $22.87.

Explanation:

The question involves finding out the maximum number of bottles of wine Nidhi can buy with her budget of $185, given that each bottle costs $22.87. To find the answer, we need to divide the total amount of money Nidhi has by the cost of one bottle of wine.

Step 1: Calculate the total number of bottles by dividing the total budget by the cost per bottle:

Total Number of Bottles = Total Budget / Cost per Bottle
Total Number of Bottles = $185 / $22.87

Step 2: Perform the calculation:

Total Number of Bottles ≈ 8.09

Since Nidhi cannot buy a fraction of a bottle, she can purchase a maximum of 8 bottles of wine with her budget of $185.

Step-by-step explanation:

There are three steps in calculating the slope of a straight line when you are not given its equation.

Step One: Identify two points on the line.

Step Two: Select one to be (x1, y1) and the other to be (x2, y2).

Step Three: Use the slope equation to calculate slope.

Take a moment to work through an example where we are given two points.

Example

Let's say that points (15, 8) and (10, 7) are on a straight line. What is the slope of this line?

Step One: Identify two points on the line.

In this example we are given two points, (15, 8) and (10, 7), on a straight line.

Step Two: Select one to be (x1, y1) and the other to be (x2, y2).

It doesn't matter which we choose, so let's take (15, 8) to be (x2, y2). Let's take the point (10, 7) to be the point (x1, y1).

Step Three: Use the equation to calculate slope.

Once we've completed step 2, we are ready to calculate the slope using the equation for a slope:

We said that it really doesn't matter which point we choose as (x1, y1) and the which to be (x2, y2). Let's show that this is true. Take the same two points (15, 8) and (10, 7), but this time we will calculate the slope using (15, 8) as (x1, y1) and (10, 7) as the point (x2, y2). Then substitute these into the equation for slope:

We get the same answer as before!

Often you will not be given the two points, but will need to identify two points from a graph. In this case the process is the same, the first step being to identify the points from the graph. Below is an example that begins with a graph.

5x-7

x would be the unknown number. for example if it were 3 you would multiply 3 and 5 to get 15 then minus 7 to get 8.

To solve the equation 7 - 4x = -12 - 3x, combine like terms and isolate x on one side of the equation. The solution is x = 19.

To solve the equation 7 - 4x = -12 - 3x, we need to isolate the variable x on one side of the equation. First, we can combine like terms by subtracting 7 from both sides:

7 - 4x - 7 = -12 - 3x - 7

-4x = -19 - 3x

Next, we can simplify the equation by adding 3x to both sides:

-4x + 3x = -19 - 3x + 3x

-x = -19

Finally, we can solve for x by multiplying both sides by -1:

x = 19

Therefore, the value of x that is a solution for the equation 7 - 4x = -12 - 3x is x = 19.

Linear equation which represents the hours Yuson has left after x days is:

30-2x

Yuson must complete 30 hours of community service.

She does 2 hours each day.

i.e. in x days, hours of service done= 2x

After x days hours of service left= 30-2x

Hence, linear equation which represents the hours Yuson has left after x days is:

30-2x

The linear equation representing the hours Yuson has left after x days is y = 30 - 2x, where y is the remaining hours and x is the number of days.

The linear equation that represents the hours Yuson has left after x days is y = 30 - 2x.

This is because Yuson must complete 30 hours of community service, and she does 2 hours each day. The equation y = 30 - 2x represents the remaining hours (y) after x days.

For example, if it's the first day (x = 1), Yuson would have 30 - 2(1) = 28 hours left. If it's the second day (x = 2), Yuson would have 30 - 2(2) = 26 hours left, and so on.

Answer:

Step-by-step explanation:

Looking at the values for [tex]y[/tex], you can see that each value is twice the previous value, which means that the missing value will be twice the previous value, which was 40, so the answer is 80.

When x = 4, the missing value is y = 80. therefore, option 80 is correct.

The table represents an exponential function, which can be expressed in the form y = ab^x, where "a" is the initial value (when x = 0), and "b" is the common ratio or base.

From the table, when x = 0, y = 5. This gives us the value of "a," which is 5.

Now, we can use this information to find the missing value when x = 4.

y = ab^x

y = 5 * b^4

To find "b," we can use another data point from the table, for example, when x = 1, y = 10:

10 = 5 * b^1

Now, solve for "b":

10 = 5b

Divide both sides by 5:

b = 10 / 5

b = 2

Now that we know the value of "b" is 2, we can find the missing value when x = 4:

y = 5 * 2^4

y = 5 * 16

y = 80

x = angle 1

3x + 12 = angle 2

angle 1 + angle 2 = 180

4x + 12 = 180

4x = 168

x = 42 = angle 1

180 - 42 = 138 = angle 2

X= the smaller smaller angle

180° = X + 3X + 12

180° - 12° = 4X

X = 168 ÷ 4

X = 42°

The question asked to solve for a number when given the difference between that number and another number is 841, and the one number is 471. By switching the subtraction problem into an addition one, we add 841 to 471 to get the larger number, which is 1312.

Explanation:

The student is asking to find a second number when the difference of it and another number is known. The information given is that the difference between two numbers is 841, and the smaller number is 471.

The question can be solved using simple subtraction in reverse, also called addition. You see, when we know the difference between two numbers and one of the numbers, we can find the other number by adding the difference to the known number, if the known number is smaller, which is the case here.

To find the missing number we simply add the difference (841) to the smaller number (471). It will look like this: 471 + 841 = 1312.

Therefore, the larger number in this pair of numbers is 1312.

Answer:

  8×10⁻³

Step-by-step explanation:

You want the value 0.00792398 rounded to the nearest thousandth.

The digit in the place to the right of the thousandth place is 9 in the ten-thousandths place. That is greater than 4, so the digit in the thousandths place needs to increase by 1 before other digits are dropped. The result is ...

  0.008 = 8×10⁻³

To estimate 0.00792398 to the nearest thousandth, round the number to the third decimal place. As the fourth decimal is 9, we round up to get 0.008. This expressed as single digit times a power of ten becomes 8 * 10^-3.

In this problem, you are asked to estimate 0.00792398 to the nearest thousandth. That means you need to round the number to the third decimal place. Firstly, you look at the fourth decimal place, which is 9. If this digit is 5 or more (which it is in this case), we round the third decimal number up. So 0.00792398 rounded to the nearest thousandth becomes 0.008.

Now, to express the answer as a single digit times a power of ten, you would express 0.008 as 8 * 10^-3. This is because -3 powers of ten move the decimal place three places to the left and leaves us with the original number 0.008.

There are 13,782.47 feet in 4.2 kilometers ⇒ answer A

Step-by-step explanation:

- Cilia cycles 4.2 km every morning

- We need to convert the kilometers to feet

- 1 mile = 1.609 kilometers

- 1 mile = 5,280 feet

* Lets do that

∵ 1 mile = 1.609 km

∵ 1 mile = 5,280 feet

- Equate them

∴ 1.609 km = 5, 280 miles

* Now we can use the cross multiplication to find how many feet in

 4.2 kilometers

→    km       :    feet

→   1.609    :    5,280

→   4.2        :    x

- By using cross multiplication

∴ 1.609 x = 4.2 × 5,280

- Multiply 4.2 by 5,280

∴ 1.609 x = 22176

- Divide both sides by 1.609

∴ x = 13782.47

∵ x represents the number of feet in 4.2 kilometers

∴ There are 13,782.47 feet in 4.2 kilometers
