Which compound inequality represents the length, w, of the essay?

Answer:

Step-by-step explanation:

Identify the first term of the sequence. First terms are -24, 13, 28. Find the matching f(1). There are two choices for each first term.

Then determine the relation of each term to the previous term. In two of the sequences, a factor of 4 is involved. For the sequence starting with -24, the adjacent terms have the same sign, so the factor is +4. For the sequence starting with 28, adjacent terms have alternating signs, so the factor is -4.

For the sequence starting with 13, the second term is 3 times the first, but it is also 26 added to the first. You have to look at the next term to see if the sequence is geometric with a ratio of 3, or arithmetic with a difference of 26. The latter is the case, so the recursive definition will involve addition, not multiplication.

The recursively defined functions are shown above in the order of the given sequences.

Answer:

25 nickels and 23 quarters

Step-by-step explanation:

The smallest possible integer solution is 23 nickels and 25 quarters.

23×0.05 + 25×0.25 = 1.15 + 6.25 = $7.40.

That's already over $7.00.

We can't solve the problem as stated unless we use fractional numbers of coins, and that's impossible.

Assume the correct ratio is 25/23

Let n = number of nickels

and q = number of quarters. Then we have two conditions.

(1)                                n/q = 25/23

(2)             0.05n + 0.25q = 7

(3)                                    n = (25/23)q     Multiplied (1) by q

(4) 0.05(25/23)q + 0.25q = 7                  Substituted (3) into (1)

          0.05435q + 0.25q = 7                  Simplified

                          0.3043q = 7                  Combined like terms

(5)                                   q = 23              Divided each side by 0.3043

                                 n/23 = 25/23         Substituted (5) into (1)

                                       n = 25              Divided each side by 23

There are 25 nickels and 23 quarters.

Check:

(1) 25/23 = 25/23     (2) 0.05×25 + 0.25×23 = 7

                                                     1.25 + 5.75 = 7

                                                                     7 = 7

OK.  

h = 800

In this question, we're trying to find the value of h.

Lets set up an equation:

[tex]1.5/100 * h = 12[/tex]

With the equation above, we can solve it to find the answer.

[tex]1.5/100h = 12\\\\\text{We would first divide 1.5 by 100}\\\\0.015h=12\\\\\text{Now, we would simply divide}\\\\h=800[/tex]

When you're done solving, you should get 800.

This means that h = 800

To check if it's correct, we could multiply 800 by 0.015 (1.5%) to see if it gives us 12.

[tex]800*0.015=12[/tex]

Now, we can confirm that the answer is h = 800

Answer:

Step-by-step explanation:

tan(55°)=15/b

b=15/tan(55°)

=10.5

Answer:

AC ≈ 10.5

Step-by-step explanation:

tan55° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{15}{b}[/tex]

Multiply both sides by b

b × tan55° = 15 ( divide both sides by tan55° )

b = [tex]\frac{15}{tan55}[/tex] ≈ 10.5

Hence b = AC ≈ 10.5 ( to the nearest tenth )

Completing the square in mathematics is a technique used to solve quadratic equations by transforming them into a perfect square trinomial form. It helps in finding the roots of the equation more efficiently.

Completing the square involves transforming a quadratic equation into a perfect square trinomial form to solve it. In the case of x^2 - 8x = 3, the steps would include halving the coefficient of x, squaring that value, and adding/subtracting it to both sides of the equation to complete the square.

The solution set for the equation x^2 - 8x = 3 would be {4 + √19, 4 - √19}, as completing the square helps in finding the roots of the quadratic equation.

Completing the square is a helpful technique in mathematics for solving quadratic equations more easily and efficiently.

The study of proportions in triangles involves understanding similar triangles' corresponding side ratios and how area scales with linear dimensions. The ratios help determine unknown lengths and compare triangles, and the square of the scale factor relates to how area changes.

Understanding Proportions in Triangles

Proportions play a crucial role in the study of triangles, particularly when dealing with similar triangles. Similar triangles have corresponding sides that are in proportion and this concept can be applied in various problems to find unknown lengths or to compare triangles. For instance, if two triangles are similar, then the ratio of their corresponding sides are equal. This can be denoted as a₁ = A₁/A2 or a3 = A3/A2, where A1, A2, and A3 represent the lengths of the sides in one triangle, and a1 and a3 are the proportional sides in the other.

Area scaling is another important concept derived from proportions. If a triangle's sides are scaled by a factor, its area scales by the square of that factor. For example, if the sides of one triangle are twice as long as the sides of a similar triangle, the area of the larger triangle is four times greater, since 2 squared equals 4. This principle can be easily demonstrated by cutting the larger triangle into four smaller triangles identical to the original smaller one, showing that the larger triangle has four times more area as illustrated in fig. (b).

In summary, proportions are crucial when working with similar triangles and understanding how changes in linear dimensions affect the area of a triangle. When comparing triangles, the ratios of corresponding sides and areas can provide valuable insights and are foundational in various applications within geometry.

Answer:

34 cans. If you set it up as ratios (5/2.85 = x/19.38), make the number of cans you need to know "x" and solve for x.

Final answer:

To determine how many cans of baked beans can be bought for $19.38, divide $19.38 by the cost of each can, which is found by dividing the total cost of 5 cans by 5. The result is that you can buy 34 cans of baked beans for $19.38.

Explanation:

To find out how many cans of baked beans can be bought for $19.38, we need to determine the cost of each can. Given that 5 cans of baked beans cost $2.85, we can divide the total cost by the number of cans to find the cost of each can: $2.85 ÷ 5 = $0.57 per can.

Next, we divide the amount of money we have, $19.38, by the cost of each can to find the number of cans we can buy: $19.38 ÷ $0.57 = 34 cans.

So, for $19.38, we can buy 34 cans of baked beans.

Then you would look through it to see how many nuts there are all together, and you would addum up.

4nuts - 2nuts = 2 nuts

Then you would write these results on one line:

15monkeys + 2nuts .

Why should it be a big tough deal when  there's just a bunch of m's and n's ?

First, just look through it to see how many m's there are all together, and addum up:

Answer:

8ft sq is your area.

Step-by-step explanation:

Solve the area of a triangle by using the following equation:

Area (of a triangle) = 1/2(base * height)

Note:

Height = 4 feet

Base = 4 feet

Plug in the corresponding numbers to the corresponding variables.

Area = 1/2(base * height)

Area = 1/2(4 * 4)

Solve. Follow PEMDAS. First, solve the parenthesis, then divide:

Area = 1/2(4 * 4)

Area = 1/2(16)

Area = 16/2

Area = 8

8ft sq is your area.

Increases by 25% :- it is 80 * 1.25 = 100.

100 decreased by 25% = 100 * 0.75

= 75.

Answer:

75

Step-by-step explanation:

We are given that 80 is increased by 25% and then decreased by 25% so we are to find the final value.

Increase of 25% in 80 = 25% of 80

= 25/100 × 80

= 20

So our new value after 25% increase = 80 + 20 = 100

Now this new value is decreased by 25% = (100 - 25)% of 100

= 75/100 × 100

= 75

Answer:

2nd choice

Step-by-step explanation:

How you have to is multiply the coordinates by 2 since the scale factor you want to dilate image at is at 2.

That is the pre-image is (x,y) and the image is (2x,2y) per each point.

A(3,5) becomes A'(3*2,5*2)=A'(6,10)

B(6,1) becomes B'(6*2,1*2)=B'(12,2)

C(5,9) becomes C'(5*2,9*2)=C'(10,18)

So 2nd choice.

The coordinates of the dilated triangle are (6,10) , (12,2) and (10,18)

The scale factor is a measure for similar figures, who look the same but have different scales or measures

A' = (3 x 2, 5 x 2) = (6, 10)

B' = (6 x 2, 1x 2) = (12,2)

Similarly C' will be (10 , 18)

So the coordinates of the dilated triangle are (6,10) , (12,2) and (10,18)

So option B is correct.

Step-by-step explanation:

here is your answer

i hope this is what u want

In this question the number that is in the 4th decimal place is...

56.0649702307

Nine is the 4th decimal, so this is the number that you will determine if it gets rounded or not.

This question wants you to have four decimal places left after you finish rounding

To determine if you round up or stay the same you must look at the number after the asked decimal place. In this case the number after the 4th decimal is 7. A number will round up if this number (7) is 5 or greater. If it is smaller then 5 then the decimal will not round up.

In this case 7 is bigger then 5. This means that the 4th decimal place (9) will round up

56.0650

^^^Since the fourth decimal is 9 when you round up the next number is ten. This means that the rounding will be bumped to the number in front of the 9 and the 9 will simply become zero.

Because the translation is 4 units towards the right, it will be x + 4

and because it is 3 units down, it will be y - 3

(x,y) → (x + 4, y - 3)

Step-by-step explanation:

Final answer:

The translation of a triangle 4 units right and 3 units down is described by the rule (x, y) → (x+4, y-3).

Explanation:

The rule that describes the translation of a triangle 4 units to the right and 3 units down in the coordinate plane can be represented as (x, y) → (x+4, y-3). This represents a translation where each point (x, y) of the triangle is moved to a new point obtained by adding 4 to the x-coordinate and subtracting 3 from the y-coordinate. In terms of transformation geometry, this rule effectively shifts the entire shape without rotating, resizing, or otherwise distorting it.

The salesman earned $280 in commission last month, which was calculated by taking 40% of the $700 worth of merchandise he sold.

This question is about calculating commission which falls under the topic of percentage calculations in math. The salesman earns a 40% commission on the merchandise he sells. So, to find out how much he earned in commission last month, we need to calculate 40% of the total value of merchandise he sold, which is $700.

To do this, multiply $700 by 40% (or 0.4 in decimal form). That would give you $280. So, the salesman earned $280 in commission last month.

https://brainly.com/question/6615293

#SPJ3

To find out how much commission the salesman earned, we need to calculate 40% of the $700 worth of merchandise that he sold. The commission rate is expressed as a percentage, which we can also write as a decimal for the purpose of calculation.
First, let's convert the commission rate from a percentage to a decimal. To do this, we divide the percentage by 100:
40% / 100 = 0.40
Now that we have the commission rate as a decimal, we can calculate the commission by multiplying the sales amount by the commission rate.
The calculation is as follows:
Commission = Sales Amount × Commission Rate
Commission = $700 × 0.40
Calculating this gives us:
Commission = $280
Therefore, the salesman earned $280 in commission last month.

Step-by-step explanation:

If equal changes in x result in equal changes in y, then the function is linear.

A. Are the changes from (2, 4) to (4, 1) and from (4, 1) to (6, 11) equal?

The change from (2, 4) to (4, 1):

When x changes from 2 to 4, the change is 4 - 2 = 2.

y changes from -9 to 1; the change is 1 - (-9) = 10

The change from (4, 1) to (6, 11):

When x changes from 4 to 6, the change is 6 - 4 = 2.

y changes from 1 to 11; the change is 11 - 1 = 10

For a change in x of 2, the change in y is 10 in both cases. This function is linear.

B. Are the changes from (2, -14) to (4, -16) and from (4, -16) to (6, -18) equal?

The change from (2, -14) to (4, -16):

When x changes from 2 to 4, the change is 4 - 2 = 2.

y changes from -14 to -16; the change is -16 - (-14) = -2

The change from (4, -16) to (6, -18):

When x changes from 4 to 6, the change is 6 - 4 = 2.

y changes from -16 to -18; the change is -18 - (-16) = -2

For a change in x of 2, the change in y is -2 in both cases. This function is linear.

C. Are the changes from (2, 0) to (4, 6) and from (4, 6) to (6, 16) equal?

The change from (2, 0) to (4, 6):

When x changes from 2 to 4, the change is 4 - 2 = 2.

y changes from 0 to 6; the change is 6 - 0 = 6

The change from (4, 6) to (6, 16):

When x changes from 4 to 6, the change is 6 - 4 = 2.

y changes from 6 to 16; the change is 16 - 6 = 10

For a change in x of 2, the change in y is 6 in one case and 10 in the other case. This function is not linear.

D. Are the changes from (2, -9) to (4, -6) and from (4, -6) to (6, -3) equal?

The change from (2, -9) to (4, -6):

When x changes from 2 to 4, the change is 4 - 2 = 2.

y changes from -9 to -6; the change is - 9 - (-6) = -3

The change from (4, -6) to (6, -3):

When x changes from 4 to 6, the change is 6 - 4 = 2.

y changes from -6 to -3; the change is -6 - (-3) = -3

For a change in x of 2, the change in y is -3 in both cases. This function is linear.
