Answer:

our initial is 3

a1=3

difference or d = 4

The general formula is an = a1+(n-1)*d

an= 3+(200-1)*4

an=3+199*4

an=3+396

an = 399

therefore the 200th item is 399

Using proportions, it is found that Carl would have 60 more hits in 500 turns.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

Billy's proportion is of 28/100, hence his amount of hits in 500 turns is:

500 x 28/100 = 140 hits.

Carl's proportion is of 1/2.5, hence his amount of hits in 500 turns is:

500 x 1/2.5 = 200 hits.

The difference is:

200 - 140 = 60 hits.

Carl would have 60 more hits in 500 turns.

Step-by-step explanation:

Perimeter is 2x + 2y = 28 (y is the length BTW)

To find y, transfer equations

28-2x=2y

Divide both sides by 2

14-x = y

Now you have your length in terms of x

Multiplt length and width

x(14-x)

First, we'll determine how many different ways the five cubes may be arranged in a column using the multiplicand rule:

5 * 4 * 3 * 2 * 1 = 120

We have five cubes to place at the base of the column, four for the second position, three for the third position, and so on until all the cubes are organized.

Then we'll calculate how many different ways we may arrange the five cubes so that they'reBlue cubos twirl around one another. In this case, we would count the two blue cubes as though they were only one, which means that we would only have "4 cubes" and be able to arrange them in 24 different ways:

4 * 3 * 2 * 1 = 24

On the other hand, the two blue cubes can be arranged in one of two different ways: first the clear, then the dark, or first the dark, then the clear.

That is to say, there are 24 different ways to arrange the cubes so that the light comes on first and the dark follows, and there are 24 different ways to arrange the cubes so that the dark comes on first and the light follows.

This means that 48 of the 120 ways to organize the five cubes contain the cubes. 72 (120-48) formas los dos cubos azules no se tocan entre sí.

There is a difference between the expressions -x/y and -x/-y

The expressions are given as:

-x/y and -x/-y

When the expression -x/-y is evaluated, we have:

-x/-y = x/y

This means that

-x/y = -x/y

-x/-y = x/y

When the above expressions are compared, we can see that both expressions are not equal

Hence, there is a difference between the expressions -x/y and -x/-y

Based on the calculation below, the after-tax return to the corporation is $3.16 per share or 6.44% if expressed in percentage.

The after-tax return can be calculated using the following formula:

After-tax return = Total return * ( 100% - tax rate) .............. (1)

Where:

Total return Received = Dividend received + Change in price = $4 + ($49 - $49 ) = $4 + $0 = $4

Tax rate = 21%

Substituting the values into equation (1), we have:

After tax return = $4 * ( 100% - 21%)

After-tax return = $3.16 per share

The after-tax return can also be expressed in percentages as follows:

After-tax return in percentage = After-tax return / Share price = $3.16 / $49 = 0.06444897 = 6.44%

Answer: -5<=x≤3   ==> 3rd option

Step-by-step explanation:

(x-3)(x+5)≤0

x-3>=0 and x+5≤0

x>=3 and x≤-5      ==> Not possible since a number subtracted by 3 can't be greater than the same number added by 5.

x-3≤0 and x+5>=0

x≤3 and x>=-5 ==> -5<=x≤3   ==> 3rd option

The solution to the inequality is {x | -5 ≤ x ≤ 3}, option C is correct.

a relationship between two expressions or values that are not equal to each other is called 'inequality.

The given inequality is (x-3)(x+5) ≤0

To solve this inequality, we first find the critical points by setting the expression inside the inequality to zero:

(x-3)(x+5) = 0

This gives us two critical points: x=3 and x=-5.

We want to find where the expression is less than or equal to zero, so we include the endpoints of the intervals where the expression is zero or negative.

Hence,  the solution to the inequality is {x | -5 ≤ x ≤ 3}, option C is correct.

Let the angles be x and y.

Their ratio is 5/3:

Their sum is 128:

Solve the system by substitution:

Find x:

Answer:

A. 72°

D. 144°

E. 216°

Step-by-step explanation:

are you tempted to calculate the internal angles ?

that is, I guess, the trap set by your teacher here, and it would be the wrong approach.

nevertheless, quickly just as a reminder :

the sum of all internal angles in a polygon is

(n - 2)×180°

n being the number of sides.

in our case that is

(5 - 2)×180 = 3×180 = 540°

so, each internal angle is 540/5 = 108°.

but we are not turning at an edge or vertex. no, we are turning the pentagon around is central point.

we are running each vertex along a circle arc. the center of that circle being P.

after every 1/5 of the circle arc there is a vertex of the pentagon.

and whenever we rotate one vertex on top of the next one, we carry the pentagon visually onto itself.

so, instead of a full circle rotation we need only 1/5 of that :

360 / 5 = 72°

and with every additional 1/5 of the circle arc (or 72°) we get it again.

that means at

72°

144°

216°

288°

360°

the pentagon carries onto itself.

therefore, A, D and E are correct.

Answer:

The correct option is 1.

Step-by-step explanation:

We have to find a function where f(2)=4. It means the value of function is 4 at x=2.

In graph 1, the value of function is 4 at x=2, therefore option 1 is correct.

In graph 2, the value of function is -4 at x=2, therefore option 2 is incorrect.

In graph 3, the value of function is not shown in the graph at x=2, therefore option 3 is incorrect.

In graph 4, the value of function is not shown in the graph at x=2, therefore option 4 is incorrect.

Thus, correct option is 1.

Based on the given scale, the number, 1, on the number line would best be represented by the number A. 8/8.

Based on the first number given which is 1/8, we know that the scale is such that the denominator would be 8.

The best way to write 1 would therefore be to express it in terms of a ratio with 8 being the denominator.

That would mean that 1 would be 8/8 which results in 1.

Answer:

because it is a square, you just need to make a square with the side lenghts all being a or b

Step-by-step explanation:

Formula we use,

→ P = 2(L + W)

Then the value of L and W is,

→ P = 2(L + W)

→ 48 = 2(2x + x)

→ 2(3x) = 48

→ x = 48/6

→ [ x = 8 ]

Then the width will be,

→ W = x = 8 ft

Hence, the width is 8 ft.

Now the length will be,

→ L = 2x = 2(8) = 16 ft

Therefore, the length is 16 ft.

Using point estimation, the sample proportion falls between 0.2 and 0.4.

The sample distribution offers details on the point estimator to choose. If the distribution's mean matches the actual value of the population parameter, the estimator is considered to be impartial. As a result, the population percentage p and the sample proportion p ought to be quite similar.

The correct option is C, because the average of 0.2 and 0.4 is 0.3
