Answer:

-$15

Step-by-step explanation:

To find the average yearly change, divide -120 by 8, since it has decreased by $120 over 8 years.

-120/8

= -15

So, the average yearly change in the value of the card is -$15

Answer:

$120/8= $15 in a year.

15 times 8 is 120.

Answer:

For 6 chairs, 72 screws and for 9 chairs, 108 screws.

Step-by-step explanation:

So, for every 2 chairs, he needs 24 screws.

By Unitary Method,

We get screws needed for one chair, that is, 24/2 = 12 screws for one chair.

So, for 6 chairs,

Similarly, for 9 chairs,

Answer:

The ratios to this would be:

[tex]\left[\begin{array}{ccc}2&24\\6&72\\9&108\end{array}\right][/tex]

Step-by-step explanation:

Ratios are similar to fractions, in some ways, ratios are to show the relation between two numbers, such like a proportion:

For example:

4:3

or the ratio of men' jobs to women's' is 8 to 1 (8:1)

In this case, it is said that:

Gary needs 24 screws for every 2 chairs.

The ratio of this is 24: 2

Also meaning:

[tex]\frac{24}{2}[/tex]

and [tex]2\sqrt{24}[/tex], the quotient is = 13

Now we multiply 12 to '6' and '9'

You will get:

12(6) = 72

12(9) = 108

This will be your answer.

Answer:

Step-by-step explanation:

we are expected to calculate how much each player is making per game, compare the values and tell who makes more money per game

Clayton Kershaw

given data

$30.15 million per year

There are 162 games in a major league baseball season.

therefore a game will be worth

=30,150,000/162

=$186,111

Carmello Anthony

given data

$24.81 million per year

There are 82 games in a NBA season.

therefore a game will be worth

=24,810,000/82

=$302,561

from the analysis, Carmello Anthony make more money per game

A line of symmetry will connect a vertex and a midpoint on an opposite side of a regular heptagon  has 7-fold symmetry.

" Symmetry is defined as the line which divides the geometrical shape into two equal proportion."

According to the question,

Regular heptagon is a polygon with 7equal sides.

Line of symmetry will connect a vertex and a midpoint of an opposite sides.

There are seven such possibilities.

Number of lines of symmetry in regular polygon is same number of sides of polygon.

Hence, regular heptagon has 7-fold symmetry.

Answer:

The population of the United States is 387.87 times larger than the population of Columbus, Ohio.

Step-by-step explanation:

8.25 times 10^5 = 825,000

3.2 times 10^8 = 320,000,000

320,000,000 divided by 825,000 = 387.87

Answer:

The rate should be 95.33 feet per second assuming that she drove with a constant speed

Step-by-step explanation:

First you divide 325 by 5. And you get 65 which is how many miles per hour she went. Then you can put it in a unit converter to change miles per hour to feet per second. And it should be 95.33 (sorry for my lack of a detailed explanation of how to transform miles per hour into feet per second)

Answer:

B

Step-by-step explanation:

Answer:

B

I copied the answer above me tbh

Step 1:

Start by setting it up with the divisor 6 on the left side and the dividend 45 on the right side like this:

   6 ⟌ 4 5  

Step 2:

The divisor (6) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:

       0    

   6 ⟌ 4 5  

Step 3:

Multiply the divisor by the result in the previous step (6 x 0 = 0) and write that answer below the dividend.

       0    

   6 ⟌ 4 5  

       0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.

       0    

   6 ⟌ 4 5  

     - 0    

       4    

Step 5:

Move down the 2nd digit of the dividend (5) like this:

       0    

   6 ⟌ 4 5  

     - 0    

       4 5  

Step 6:

The divisor (6) goes into the bottom number (45), 7 time(s). Therefore, put 7 on top:

       0 7  

   6 ⟌ 4 5  

     - 0    

       4 5  

Step 7:

Multiply the divisor by the result in the previous step (6 x 7 = 42) and write that answer at the bottom:

       0 7  

   6 ⟌ 4 5  

     - 0    

       4 5  

      4 2  

Step 8:

Subtract the result in the previous step from the number written above it. (45 - 42 = 3) and write the answer at the bottom.

       0 7  

   6 ⟌ 4 5  

     - 0    

       4 5  

     - 4 2  

         3  

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 45 divided by 6 calculated using Long Division is:

Answer:

[tex]-9.31x^2+56.26x[/tex]

Step-by-step explanation:

Let the quadratic function be:

[tex]h=ax^2+bx+c[/tex]

Where [tex]h[/tex] is the height of soccer ball and

[tex]x[/tex] is the time in seconds.

Initially, at time [tex]x=0\Rightarrow h=0[/tex]

Therefore, [tex]c=0[/tex]

Given that,

[tex]x=3, h=85\\and\\x=6, h=2.5[/tex]

Putting the values and making equations in [tex]a,b[/tex] :

[tex]85=9a+3b\\2.5=36a+6b[/tex]

By solving the above equations, we get:

[tex]a=-9.31\\ and\\b =56.26[/tex]

So, the quadratic expression is:

[tex]-9.31x^2+56.26x[/tex]

Given parameters:

    x = 150 minus 6 y

Interpreting this gives;

    minus = subtraction  = -

        x  = 150 - 6y

Now bring the variables together;

                    x + 6y  = 150

The option that matches with this equivalent.

The other choices are wrong;

   a,  x + 150 = 6 y

           x - 6y = 150   wrong

 c. 2x + 3y = 75   mulitply through by 2;

      2(2x + 3y) = 2(75)

        4x + 6y  = 150      wrong

   d. 2x - 3y = 75

    Multiply by 2;

     2(2x -3y) = 2(75)

      4x - 6y = 150

Answer:

x+6y = 150 (B)
