Attendance i decreaing at a rate of 0. 5% per year. If there are 1200 people attending now how many will be attending in 4 year?

Answer:
1. y = 1/4x-1 or y = 0.25x-1

Step-by-step explanation: Hello! You can do this by using the slope-intercept equation.  The slope-intercept formula is y = mx+b.  You have the x and y coordinates already, which is all you need to solve the equation.  m = slope, b = y-coordinate in the formula y = mx+b.  The first thing you have to do is find the slope.  To find the slope, use the formula (y2 - y1)/(x2-x1).  The y-coordinates are the second numbers in the coordinate pairs, and the x-coordinates are the first numbers in the coordinate pairs.  Put the information in the formula.  You now have: (0 - (-2))/(4 - (-4)).  Two negatives make a positive, so you can simplify this equation by writing (0 + 2)/(4 + 4).  Add both equations.  You now have 2/8.  You can simplify this even more by dividing the numerator and denominator by 2.  2/8 divided by 2/2 = 1/4.  You now know the slope is 1/4.  

The next thing you have to do is use the point-slope formula.  The point-slope formula is y - y1 = m(x - x1).  m = slope, so put the slope you know (1/4) in the equation.  y - y1 = 1/4(x - x1).  You also know that y1 = -2 and x1 = -4 from the given coordinate pairs.  Fill this information in.  
y - (-2) = 1/4(x - (-4)).  Two negatives make a positive, so you can simplify this into: y + 2 = 1/4(x + 4).  Distribute 1/4 to x and -4.  1/4 x x = 1/4x, and 1/4 x 4 = 1.  You now have y + 2 = 1/4x + 1.  Subtract 2 from both sides.  y + 2 - 2 = 1/4x + 1 - 2. You now have y = 1/4x-1.  This is in the format y = mx+b, which is what you are supposed to do.  The answer for question 1. is y = 1/4x-1.  Hope this helps you with the rest of the problems! If you still need help after this, I can teach you how to do the second question as well.

The greater than sign is '>' . If one value is greater than the other, use greater than. For example, 8 is greater than 7. Therefore, we can write greater than 7 is x >7.

Greater than symbol:

In mathematics, the greater than sign is placed between two values ​​where the first number is greater than the second number. For example, 10 > 5. Here 10 is greater than 5. For inequalities, the greater-than sign always refers to the greater value, and the sign consists of two equal length dashes joined at an acute angle on the right.

As we know math problems don't always end evenly. We may need to include inequalities such as greater than and less than signs. Statements can be expressed as mathematical expressions.

Example: 'x' is the number of students in the class. If she has more than 45 students in her class, and she has 5 students join her class again, then she has more than 50 students in her class. This statement is expressed mathematically as x + 5 > 45. fish . Crocodiles always want to eat more fish, so they can eat more fish, regardless of how many mouths they have open.

One of the best ways to remember the "greater than" and "less than" signs is to think of them as little alligators (or crocodiles). The numbers on either side represent the number of fish. Crocodiles always want to eat more fish, so they can eat more fish, regardless of how many mouths they have open.

Step-by-step explanation:

the ratio is 25/50 (25 kg in 50 minutes).

as a ratio is basically a fraction (just with a special meaning), we can simplify it as a "normal" fraction :

25/50 = 1/2

in other words, the hippo can eat 1 kg in 2 minutes.

now the answer to the question is easy :

how many minutes to eat 60 kg ?

remember, when we multiply one part of the fraction by a factor, we need to multiply the other post by the same factor to keep the overall value.

so, 60 kg = 60×1 kg

we multiply the numerator by 60, therefore, we need to multiply the denominator by 60 too. and we get

1/2 × 60/60 = 60/120

it takes the hippo 120 minutes to eat 60 kg.

The triangles ΔUVW are ΔUKL discovered to be similar by AA Similarity theorem.

Similar triangles are defined as triangles that have the same shape, but then their sizes may differ. Thus, if two triangles are said to be similar, then it means that their corresponding angles are congruent and  also their corresponding sides are in equal proportion

There are three triangle similarity theorems, namely; Angle-Angle (AA), Side-Angle-Side (SAS) or Side-Side-Side (SSS).

Now, looking at the given image, we see that ∠UVW ≅ ∠UKL because they are both corresponding angles.

Similarly, we can say that ∠UWV ≅ ∠ULK because they are corresponding angles.

The measure of ∢1 is 40 degrees.

What is the measure of angle?

The measure of an angle is a numerical value that represents the amount of rotation of one ray around a common endpoint, called the vertex, compared to another ray. The measure of an angle is usually measured in degrees (°).

The measure of an angle can be found by using the following formula:

Measure of ∢1 = 180 - (measure of ∢2 + measure of ∢3)

In this case, we are given the measures of ∢2 and ∢3:

∢2 = 102 degrees

∢3 = 38 degrees

So, we can substitute these values into the formula:

Measure of ∢1 = 180 - (102 + 38) = 180 - 140 = 40 degrees

Therefore, the measure of ∢1 is 40 degrees.

The average cost is the total cost of goods divided by the number of units produced or sold. It is used to determine the cost of each unit produced or sold. Without more information about your costs and the number of products you have produced or sold, it is not possible to determine the average cost.

To calculate the average cost of the product, you will need to subtract the gross margin percentage from 100% and then divide the result into the selling price.

First, convert the gross margin percentage to a decimal: 3% = 0.03

Then, subtract the gross margin from 1: 1 - 0.03 = 0.97

The difference between the largest 7-digit and the smallest 8-digit number is 1.

The aim is to find the largest 5-digit and the smallest 8-digit numbers, and then we need to determine the difference between these two values.

Let's start by finding the smallest 8-digit number.

We know that 0 is the smallest digit that can not be used in the highest place value, so we will consider the next smallest digit, 1; therefore, it can be used in the highest place value.

Thus, we can create the required 8-digit smallest number with 0 and 1.

Hence, the smallest 8-digit number is 10000000.

Now, we will discover the largest 7-digit number.

As we know, the largest digit is 9, which can be used anywhere. So, we will form the largest 7-digit number with the digit 9.

Thus, the largest 7-digit number is 9999999.

Now, find the difference between these two values.

So, we can determine the difference between the smallest 8-digit number and the largest 7-digit number by subtracting the smallest from the largest.

Thus, we get,

⇒10000000 - 9999999

⇒1

Hence, 1 is the difference between the smallest 8-digit and the largest 7-digit numbers.

Refer to the image attached. We can write in ΔCEB as -

Answer:The steps in solving the quadratic function 7x – 9 = 7x^2 – 49x by completing the square are as follows:

Add and subtract (49/2)^2 = (36) to the right-hand side of the equation to complete the square. This gives us:

7x - 9 = 7x^2 - 49x + 36

Factor out the coefficient of the x^2 term, which is 7, on the right-hand side of the equation. This gives us:

7x - 9 = 7(x^2 - 7x + 6)

Take the square root of the number inside the parenthesis and add and subtract it, to get:

7x - 9 = 7(x - 3.5)^2 - 2.25

Now we can add 9 to both sides of the equation to get:

7x = 7(x - 3.5)^2 + 0.75

Now we can divide both sides by 7 to get:

x = (x - 3.5)^2 + 0.75/7

Now we can solve the equation by taking the square root of both sides and adding and subtracting 3.5 to get:

x = 3.5 ± √(x^2 - 7x + 6)

Now we have our solutions, x = 3.5 + √(x^2 - 7x + 6) and x = 3.5 - √(x^2 - 7x + 6) which are the solutions of the quadratic equation.

One ft2 of sod costs $10.14 and one pot of ivy costs $0.24

Step-by-step explanation:

We can use the information provided to find the cost of one ft2 of sod and the cost of one pot of ivy.

To find the cost of one ft2 of sod, we can divide the total cost of sod by the total area of sod:

Cost of 1 ft2 of sod = (71 / 7) = $10.14/ft2

To find the cost of one pot of ivy, we can divide the total cost of ivy by the total number of pots:

Cost of 1 pot of ivy = (76 - 71) / (11 + 10) = $5 / 21 = $0.24/pot

So one ft2 of sod costs $10.14 and one pot of ivy costs $0.24

Keep in mind that these calculations only give approximate prices since it's not specified that the cost of ivy and sod is the same, but it's just an estimation based on the information that you provided.
