The number of people visited the zoo from the state is  200

Number deals with quantity of people that came to the zoo from the state over the period.  These people must be from the state.

The given parameters that will help us to solve the question are:

The ratio is approximately 7 to 3.

The number of people = 2000

The sum of the ratios is equal to 7+3 = 10

This is to say that 10% of the people visited the zoo

10/100*2000/1

Therefore about 200 people visited the zoo

The quadratic equation written in the vertex form is:

f(x) = 2*(x - 2)^2 - 8

We know that for any parabola whose vertex is (h, k) and the leading coefficient is a, can be written in the vertex-form as:

f(x) = a*(x - h)^2 + k

In this particular case, we know that the vertex of the parabola is the point (2, -8), replacing that in the quadratic equation above we will get:

f(x) = a*(x - 2)^2  - 8

Now we also know that our parabola passes through the point (0, 0), then if we replace these values in the equation we will get:

f(0) = 0 = a*(0 - 2)^2 - 8

        0 = a*4 - 8

        8 = a*4

        8/4 = a

          2 = a

Then the quadratic equation in the vertex form is:

f(x) = 2*(x - 2)^2 - 8

The maximum number of drinks Liam can buy is 4 without over exceeding his price.

Unitary method:

The unit method is a method of obtaining a single-unit value from a multiple-unit value and obtaining a multiple-unit value from a single-unit value. This is the method used for most calculations in mathematics. This method is useful when solving problems involving proportions and proportions, algebra, geometry, and more.

The unit method allows us to find missing values. For example, if a pack of juice costs $5. Then you can easily see that the cost is 5 packages, or $25.

According to the Question:

If Liam has $30 to spend and he must buy at least 9 drinks and tacos altogether, it means that,

$3.50 for 5 tacos

⇒ 3.50 x 5 =  $17.50

Now,

9 - 5 tacos = 4 drinks

Cost of 4 drinks x $2 = $8

The total price :

$17.50 + $8 = $25.50 out of $30 price limit

Thus, the number of drinks that she could buy is 4.

Translation type of transformation can be defined as moving a figure to a new location with no change to the size or shape of the figure.

Now, According to the question:

Type of Transformation:

There are four types of transformation in geometry, namely translation, reflection, rotation, and dilation. In translation, it slides the figure in any direction while in reflection, it flips the figure over a point or a line. Also, in rotation the figure turns, while in dilation the figure is either enlarged or reduced.

The type of transformation can be defined as moving a figure to a new location, without any change in the figure's size or shape being called translation. In translation, the figure merely slides or moves in the same direction and distance.

Answer:

[tex]y= \frac{x}{2x−1}[/tex]

Step-by-step explanation:

To find the inverse function, swap x and y, and solve the resulting equation for x.

If the initial function is not one-to-one, then there will be more than one inverse.

So, swap the variables: y=x/2x−1 becomes x=y/2y−1.

Now, solve the equation x=y/2y−1 for y.

y=x/2x−1

Answer: You can make more bracelets than necklaces. ✅

Step-by-step explanation:

You have 2.88 meters of copper wire and 5.85 meters of aluminum wire.

With 2.88 meters of copper wire, you can make 12 bracelets because each bracelet needs 0.24 meters of copper wire.

With 5.85 meters of aluminum wire, you can make 9 necklaces because each necklace needs 0.65 meters of aluminum wire.

So you can make 12 bracelets and 9 necklaces.

Therefore you can make more bracelets than necklaces.

The first step in solving an inequality is to isolate the variable on one side of the inequality sign. This is also known as "clearing the inequality" of the variable. This can be done by using inverse operations such as addition, subtraction, multiplication, and division.

For example, if the inequality is 3x + 2 > 7, the first step is to isolate the variable x by subtracting 2 from both sides:

3x + 2 > 7

3x > 5

Then, divide both sides by 3 to get x > 5/3

This is the first step in solving an inequality, as now the variable x is isolated on one side of the inequality sign, and it's clear what the inequality is asking for.

It's important to note that when solving inequalities, it's crucial to keep the direction of the inequality sign the same, meaning if you multiply or divide by a negative number, you need to switch the direction of the inequality sign as well.

Also, it's important to check if the inequality is not valid, if the operation you are doing creates a division by zero, it will be an invalid inequality.

The triangles QRS and TUV are similar. They are similar as ΔTUV = 3ΔQRS.

What are triangles?

Triangles are a particular sort of polygon in geometry that have three sides and three vertices. Three straight sides make up the two-dimensional figure shown here. An example of a 3-sided polygon is a triangle. The total of a triangle's three angles equals 180 degrees. One plane completely encloses the triangle.

There are two similar looking triangles, ΔQRS and ΔTUV.

In ΔQRS, the measure of line segment QR = 9 units

In ΔQRS, the measure of line segment RS = 10 units

In ΔQRS, the measure of line segment QS = 11 units

In ΔTUV, the measure of line segment TU = 27 units

In ΔTUV, the measure of line segment UV = 30 units

In ΔTUV, the measure of line segment TV = 33 units

The pattern here can be seen that -

For the line segment TU -

3 (QR) = TU

3 (9) = 27

Similarly, for the line segment UV -

3 (RS) = UV

3 (10) = 30

Similarly, for the line segment TV -

3 (QS) = TV

3 (11) = 33

Therefore, the triangle TUV is three times scaled version of triangle QRS.

A constant polynomial is a polynomial with a degree of 0, meaning it has no variable terms. The only possible constant polynomial is the term with a coefficient of 3, which is 3.

This can be seen by looking at the formula for a polynomial, which is:

P(x) = a0 + a1x + a2x2 + ... + anxn,

where a0 is the constant term, a1 is the linear term, a2 is the quadratic term, and so on. Since this polynomial has no variable terms (x = 0), the only possible constant polynomial is the term with a coefficient of 3.

To calculate the value of a constant polynomial, you simply substitute 0 for x in the equation above. For example, in the polynomial 3, the value would be 3 when x = 0.

P(0) = 3

The price of the adult ticket is $9

Word problems are sentences describing a 'real-life' situation where a problem needs to be solved by way of a mathematical calculation.

Let the A and S represent the prices of adult and student ticket respectively. So we can write:

4A + 10S = 106 --- (1)

4A + 9S = 99  --- (2)

Subtracting (2) from (1) will give:

S = 7

Put S = 7 into (1):

4A + 10S = 106

4A + 10(7) = 106

4A + 70 = 106

4A = 106 - 70

4A = 36

A = 36/4

A = 9

The slope of the equation of the line 3f - s = 24 is 3.

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

Therefore, let's model the equation of the line y = mx + b to 3f - s = 24. Then, we can locate the slope in the equation.

Hence,

3f - s = 24.

add s to both sides of the equation

3f - s + s = 24 + s

3f = 24 + s

subtract 24 from both sides of the equation

3f = 24 + s

3f - 24 = 24 - 24 + s
