Answer:

  10, 12, 14   and maybe {8, 10, 12} and {12, 14, 16}, depending on the meaning of the question

Step-by-step explanation:

If x is the middle one, then their sum is 3x. You want ...

  15 < 3x/2 < 21 . . . . assuming "between 15 and 21" does not include 15 or 21

  30 < 3x < 42

  10 < x < 14

The only even integer in that range is 12, so the three integers are ...

  10, 12, 14 . . . . . half their sum is 18

__

We have used <, rather than ≤ in the above solution. This assumes that "between" does not include the values at the end of the range. If those values are included, then two additional solutions are possible: {8, 10, 12} and {12, 14, 16}. For the first set, the half-sum is 15; for the second set, the half-sum is 21.

Given:

Original price of a blouse = $21.99

Sale = 25% off

To find:

The cost of blouse during the same before tax.

Solution:

Since Shelly's Boutique had a Labor Day sale featuring 25% off any item. It means price of each item in sale is 25% less than the original price.

[tex]\text{Price of blouse during sale}=21.99-25\%\text{ of } 21.99[/tex]

[tex]\text{Price of blouse during sale}=21.99-\dfrac{25}{100}\times 21.99[/tex]

[tex]\text{Price of blouse during sale}=21.99-0.25\times 21.99[/tex]

[tex]\text{Price of blouse during sale}=21.99-5.4975[/tex]

[tex]\text{Price of blouse during sale}=16.4925[/tex]

Approximate the value to the nearest cent (2 decimal places).

[tex]\text{Price of blouse during sale}\approx 16.49[/tex]

Therefore, the cost of blouse during sale is $16.49.

Answer:

14x + 1

Step-by-step explanation:

4(2x-1)+3(2x+5) = 2x*4 - 1*4  + 2x*3 + 5*3

                          = 8x - 4 + 6x + 5

                          = 8x + 6x -4 + 5  {Combine like terms}

                          = 14x + 1

Answer:

alternate exterior angles and lines are parallel so

10x is congruent to 11x-8

second question

alternate interior angles and lines are paralles so angles are congruent

Given :

For the school's sports day, a group of students prepared 12 1/2 litres of lemonade. At the end of the day they had 2 5/8 litres left over.

To Find :

How many litres of lemonade were sold.

Solution :

Initial amount of lemonade, I = 12 1/2 = 25/2 litres.

Final amount of lemonade, F = 2 5/8 = 21/8 litres.

Amount of lemonade sold, A = I - F

A = 25/2 - 21/8 litres

A = 9.875 litres

Therefore, 9.875 litres of lemonade were sold.

Hence, this is the required solution.

Answer:

1.19

Step-by-step explanation:

The original full amount is 100%.

When you increase the full amount by 19%, you add 19% of the full amount to the full amount, so now you have 119%.

To find 119% of an amount, multiply he amount by 1.19 since 119% = 1.19

Answer: 1.19

The solution of the trigonometric inequality will be equal to π / 4.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relation between variables and the numbers.

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

Given inequality is 3 - tanx ≥ 4 - 2tanx. The inequality will be solved as,

3 - tanx ≥ 4 - 2tanx

2tanx - tanx ≥  4 - 3

tanx ≥ 1

tanx ≥  tan(π/4)

x ≥ (π/4)

Therefore, the solution of the trigonometric inequality will be equal to π / 4.

GIVE ME BRAINLIEST

Step-by-step explanation:

. We assume, that the number 10 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 10 is 100%, so we can write it down as 10=100%.

4. We know, that x is 0.034% of the output value, so we can write it down as x=0.034%.

5. Now we have two simple equations:

1) 10=100%

2) x=0.034%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

10/x=100%/0.034%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 0.034% of 10

10/x=100/0.034

(10/x)*x=(100/0.034)*x - we multiply both sides of the equation by x

10=2941.1764705882*x - we divide both sides of the equation by (2941.1764705882) to get x

10/2941.1764705882=x

0.0034=x

x=0.0034

now we have:

0.034% of 10=0.0034

Answer:

y= -2x+6

Step-by-step explanation:

use point slope form ----> y-y,=m(x-x,)

(the commas serve as ones)

y-4= -2(x-1)

use distributive property

y-4= -2x+2

add 4 to each side

y= -2x+6

Answer: 2460 kilometers

Step-by-step explanation:

Actual distance between Oaxaca and Guadalajara = 984 kilometers

Distance between Oaxaca and Guadalajara on a map = 4cm

Distance between Guanajuato and Tijuana on a map = 10cm

The actual distance between Guanajuato and Tijuana will then be:

= 984/4 × 10

= 246 × 10

= 2460 kilometers

I want to say it is 8,000

Step-by-step explanation:

go to 80 degrees and go up to the next point and that is on 8,000

Answer:

8,300

Step-by-step explanation:

If you continue the graph to 80 degrees, your average will end up at 8,300. You can tell because it will be above 8,000 but not close to 9,000 so it has to be 8,300.

Answer:

slope is -2

and y-intercept is 13

Step-by-step explanation:

[tex]slope=m=\frac{y_2-y_1}{x_2-x_1} \\m=\frac{5-3}{4-5}=\frac{2}{-1}\\slope=m= -2\\Then, we can write equation of line as y=mx+b\\y=-2x+b\\using either points given we can find b \\so using point (4,5)\\5=-2(4)+b\\so b=13\\ therefore y-intercept is = 13[/tex]

Assuming you meant to say triangle ABC is congruent to triangle DEF, then the corresponding pieces AB and DE are the same length.

In short AB = DE.

Since DE = 10, this makes AB = 10 also.

Answer:

Step-by-step explanation:

The difference of these numbers is 6, so the next two terms of an arithmetic sequence would be 8+6 = 14, and 14+6 = 20.

The ratio of these numbers is 4, so the next two terms of a geometric sequence would be 8×4 = 32, and 32×4 = 128.

Any pair of numbers can be used that is not (14, 20) or (32, 128).

The next two terms could be 0 and 1, or they could be 14 and 32.

Answer:

28,260.0 cm^3

Step-by-step explanation:

The volume of a cylinder uses the equation π[tex]r^{2}[/tex]h.To find the radius, divide the diameter by two, getting r=1/2(30)=15. Plug in all numbers getting:

3.14(15^2)(40)

=3.14(225)(40)

=28260

Answer:

V ≈ 28,260 cm³

Step-by-step explanation:

V = πr²h where,

V = volume

r = radius

h = height

π = 3.14

To find the value of the radius, we take half of the diameter.

1/2(30) = 15

Now that we have all the values, we plug them into the equation and round.

V = (3.14)(15)²(40) = 28,260

V = 28,260
