The scale factor of the model to the real-life player is 6:76. This can be read as 6/76 or 0.0789 or 0.079(approximately)

The scale factor is a ratio that compares the size of the model to the size of the real-life object. In this case, the scale factor of 6:76 tells us that for every 76 inches of the real-life player, the model is only 6 inches. In other words, the model is 6/76 or approximately 0.0789 times smaller than the real-life player.

In general, a scale factor is a number used to multiply all the dimensions of an object to get a corresponding model or representation of that object, where the ratio of the corresponding dimensions between the real-life object and the model is represented by the scale factor.

It should be noted that the scale factor can also be represented in fraction or decimal form, but the colon notation gives a more meaningful representation of the comparison of the size between the model and the real-life object.

Answer: The scale factor for the basketball player to the model is 16 inches to 1 inch

Answer:

  a) 144°

  b) 90°

Step-by-step explanation:

You want the measures of the 2nd largest, and the smallest, of the angles in a hexagon whose ratios are 5:5:6:7:8:9.

The interior angles of a hexagon will have a sum of ...

  180°×(n -2) = 180°×(6 -2) = 720°

The sum of the numbers in the given ratio is ...

  5+5+6+7+8+9 = 40

This tells us that multiplying the ratio values by 720/40 = 18 will give the angle values:

  90:90:108:126:144:162

The second largest angle is 144°.

The smallest angle, 90°, is the one that is repeated.

The cost for one pound of birdseed should be $0.67. The solution has been obtained using the unitary method.

What is a unitary method?

In the unitary method, the value of a single unit is first calculated, and only then is the value of the necessary number of units calculated. The unitary technique, to put it simply, is used to calculate the value of a single unit from a given multiple.

We know that cost per pound = Total pounds/cost

So, for Mariela

15 pounds = $10.00      

1 pound = $0.67  

For Mark,

12 pounds = $8.00  

1 pound = $0.67

For Daryl,

18 pounds = $12.00    

1 pound = $0.67

Hence, the cost for one pound of birdseed should be $0.67.

Answer: X=-6

Step-by-step explanation: Since both logarithms have a base of 9, we can simply get rid of them. We could also do 9^(log9(8-2x))=9^(log9(-3x+2)). This would eliminate the logarithms.

Now we are just left with a simple algebraic equation: 8-2x=-3x+2.

We add 3x on both sides to get 8+x=2. We subtract 8 on both sides to get x=-6. There is no need to create a domain for the values of x since this is not an inequality problem.

The solution to the equation -3x - 6 = -4x + 5 is x = 11.

What is equation?

An equation is a mathematical statement that uses an equals sign (=) to show that two expressions have the same value.

To solve for x in the equation -3x - 6 = -4x + 5, we need to isolate the variable x on one side of the equation. We can do this by adding 4x to both sides of the equation to eliminate the negative 4x term on the right-hand side:

-3x - 6 + 4x = -4x + 5 + 4x

Simplifying the left-hand side by combining like terms, we get:

x - 6 = 5

Finally, to isolate x, we add 6 to both sides of the equation:

x - 6 + 6 = 5 + 6

Simplifying the left-hand side and the right-hand side, we get:

x = 11

Therefore, the solution to the equation -3x - 6 = -4x + 5 is x = 11.

The centroid of the region in the first quadrant bounded by the curves [tex]\(y = x^9\)[/tex] and [tex]\(x = y^9\)[/tex] is [tex]\(\left(\dfrac{10}{11}, \dfrac{10}{11}\right)\)[/tex].

The centroid is given by the following formulas:

[tex]\[\bar{x} = \dfrac{\int_{a}^{b} x \cdot f(x) \, dx}{\int_{a}^{b} f(x) \, dx}\][/tex]

[tex]\[\bar{y} = \dfrac{\int_{c}^{d} y \cdot g(y) \, dy}{\int_{c}^{d} g(y) \, dy}\][/tex]

Where f(x) and g(y) are the functions that define the curves bounding the region.

Since we want to find the centroid of the region in the first quadrant, the intersection points of the two curves in the first quadrant.

The curves intersect at (1, 1).

Now, let's find the centroid of the region in the first quadrant.

First,  find the limits of integration:

1. For x:

The curve  [tex]\(y = x^9\)[/tex] is the upper curve, and it intersects the x-axis at x = 0  and the y-axis at x=1.

So, the limits of integration for x are [tex]\(0 \leq x \leq 1\)[/tex].

2. For y: The curve [tex]\(x = y^9\)[/tex] is the right curve, and it intersects the y-axis at y=0 and the x-axis at y=1.

So, the limits of integration for y are [tex]\(0 \leq y \leq 1\)[/tex].

Now,  set up the integrals:

[tex]\[\bar{x} = \frac{\int_{0}^{1} x \cdot x^9 \, dx}{\int_{0}^{1} x^9 \, dx}\][/tex]

[tex]\[\bar{y} = \dfrac{\int_{0}^{1} y \cdot y^9 \, dy}{\int_{0}^{1} y^9 \, dy}\][/tex]

1. [tex]\(\int_{0}^{1} x \cdot x^9 \, dx\):[/tex]

[tex]\[\int_{0}^{1} x \cdot x^9 \, dx = \int_{0}^{1} x^{10} \, dx[/tex]

                 [tex]= \left[\dfrac{x^{11}}{11}\right]_{0}^{1} = \dfrac{1}{11}\][/tex]

2. [tex]\(\int_{0}^{1} x^9 \, dx\):[/tex]

[tex]\[\int_{0}^{1} x^9 \, dx = \left[\dfrac{x^{10}}{10}\right]_{0}^{1}[/tex]

             [tex]= \dfrac{1}{10}\][/tex]

3.[tex]\(\int_{0}^{1} y \cdot y^9 \, dy\):[/tex]

[tex]\[\int_{0}^{1} y \cdot y^9 \, dy = \int_{0}^{1} y^{10} \,[/tex] dy

                 [tex]= \left[\dfrac{y^{11}}{11}\right]_{0}^{1} = \dfrac{1}{11}\][/tex]

4. [tex]\(\int_{0}^{1} y^9 \, dy\):[/tex]

[tex]\[\int_{0}^{1} y^9 \, dy = \left[\frac{y^{10}}{10}\right]_{0}^{1}[/tex]

            [tex]= \dfrac{1}{10}\][/tex]

Now, the centroid coordinates:

[tex]\[\bar{x} = \dfrac{\frac{1}{11}}{\dfrac{1}{10}} = \dfrac{10}{11}\][/tex]

[tex]\[\bar{y} = \dfrac{\frac{1}{11}}{\dfrac{1}{10}} = \dfrac{10}{11}\][/tex]

So, the centroid of the region is [tex]\(\left(\dfrac{10}{11}, \dfrac{10}{11}\right)\)[/tex].

At 0 seconds and 12 seconds, the electric vehicle is not moving.

The most crucial scientific notion is measurement.

Base or physical fundamental units are used to quantify a wide range of quantifiable quantities.

One such measurable metric is speed, which calculates the ratio between the distance an object travels and the time needed to cover that distance.

The distance traveled in relation to the time it took to travel that distance is how speed is defined.

Since speed simply has a direction and no magnitude, it is a scalar quantity.

When an object travels the same distance in the same amount of time, it is said to be moving at a uniform speed.

Average speed is the constant speed determined by the ratio of the total distance traveled by an object to the total amount of time it took to travel that distance.

According to our question-

At the start of the test, x: represents the time in seconds.

Y: stands for the speed, expressed in miles per hour.

Answer:

See attached graph.

Step-by-step explanation:

Given equation:

[tex]y+4=\dfrac{2}{5}(x-3)[/tex]

Expand the right side of the equation:

[tex]\implies y+4=\dfrac{2}{5}x-\dfrac{6}{5}[/tex]

Subtract 4 from both sides of the equation:

[tex]\implies y=\dfrac{2}{5}x-\dfrac{26}{5}[/tex]

Substitute x = 3 into the equation:

[tex]\implies y=\dfrac{2}{5}(3)-\dfrac{26}{5}[/tex]

[tex]\implies y=\dfrac{6}{5}-\dfrac{26}{5}[/tex]

[tex]\implies y=-\dfrac{20}{5}[/tex]

[tex]\implies y=-4[/tex]

Substitute x = -2 into the equation:

[tex]\implies y=\dfrac{2}{5}(-2)-\dfrac{26}{5}[/tex]

[tex]\implies y=-\dfrac{4}{5}-\dfrac{26}{5}[/tex]

What is fraction?

In mathematics, a fraction is represented by a number that identifies a portion of a whole. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object.

Number of guests in the graduation party, a = 40

Number of drop in guests at the graduation party,  b = 35

Now, drop-in guests are counted as half a guest, so the number becomes b = 35/2.

Total number of guests = a + b

Total number of guests = 40 + 35/2

Total number of guests = (80+35)/2

Total number of guests = 115/2

Total number of guests = 57(1/2)...

The table shows amount of food -

Food item A 26 piece, Food item B  5(2/3) pounds and Food item C  1(3/4) pounds.

Also, it recommends amount of food to order for 23 party guests.

So, number of groups having 23 people -

= 2(23) + 11.5 group

= 2(23) + 1(1/2) group...

Therefore, there should be 2(1/2) times quantity of food mentioned in the table.

For Food item A  - 26 × 2(1/2)

= 26 × 5/2

The term "income tax" describes a class of taxes that governments impose on income generated by people and businesses within their territorial jurisdiction.

Taxpayers are required by law to submit an income tax return each year in order to determine their tax obligations.

Income taxes are the main source of funding for governments. They are employed to fund public services, provide residents with goods, and settle debts owing to the government.

A number of states and municipal governments, in addition to the federal government, also require payment of income tax. The Internal Revenue Service is responsible for collecting taxes and enforcing the tax laws in the United States (IRS).

Regarding credits, deductions, and other forms of taxable and reportable income.

Firstly let us break the income tax as per the given condition

Income = 47,000 = 30,000 + 17,000

hence 20% tax is imposed on $30,000 and 40% on $17,000

Total income tax = 20% of 30000 + 40% of 17000

Total income tax = 6000 + 6800 = 12800
