Please help me how do you recognize and complete a geometric sequence

Answer:

84.82 or 27pi

Step-by-step explanation:

Area of a circle is A=pir^2

so the area of the whole circle would be 6^2pi

so area is 36pi but only 3/4 is shaded so

36pi*3/4=27pi

27*pi≈84.82

Answer:

84.78cm²

Step-by-step explanation:

Angle at the centre:

360 - 90 = 270

Area:

(270/360) × pi × r²

(3/4) × pi × 6²

27pi cm²

27(3.14) = 84.78 cm²

Answer:

Yes!

Answer:

8.5

Step-by-step explanation:

To work out the original number you would need to work backwards ( do the opposite). First you would do 22-5, this gives us 17. Then you would divide 17 by 2 to work out the original number.

1) Subtract 5 from 22.

[tex]22-5=17[/tex]

2) Divide 17 by 2.

[tex]17/2=8.5[/tex]

3) The original number was 8.5

Answer:8.5

Vincent would have 30.5 more visits, but since you can't have half a visit technically speaking, round up to 31 if it is allowed.

Step-by-step explanation:

$231 - $48 = $183

$183 divided by $6 = 30.5

Answer: 6a+27x

Step-by-step explanation:

combine 18a and -12a

combine 12x and 15 x

thus the answer

Hope I helped!

Answer:

18a + 12x - 12a + 15x

combining like terms we get

6a + 27x

Now we can take common from them

3(2a + 9x)

Step-by-step explanation:

Evan's account can be modeled by exponential growth because it compounds interest. Ethan's account can be modeled by linear growth because it accrues a fixed interest rate annually.

The account that can be modeled by exponential growth is Evan's account because it compounds interest. Compound interest involves the exponential growth formula: A = P(1 + r/n)^(nt), where A is the final account balance, P is the principal (initial deposit), r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years. In this case, Evan's account compounds interest annually, so n=1.

Ethan's account, on the other hand, can be modeled by linear growth. Linear growth is represented by a straight line on a graph, and it involves a constant rate of increase over time. Ethan's account accrues interest at a fixed 8% annually, so the amount in the account increases by the same amount every year.

Answer:

120 degrees

Step-by-step explanation:

This is a quadrilateral, and by definition, the sum of all the interior angles is 360. So, we can just sum up all the expressions and set them equal to 360:

2x + x + 2x + x = 360

Combine like terms and solve for x:

6x = 360

x = 360/6 = 60

<BCD = 2x = 2 * 60 = 120

Thus, the answer is 120 degrees.

Hope this helps!

Answer:

10%= 40$ 30%=120$

Step-by-step explanation:

ok so u earn 400$ at a yard sale. you divide it by 100 400/100=4. ok so then you multiply four by 10=40 and that is 10% multiply it by 30 u get 120 or 30%

sorry for the bad spelling

To find out how much to donate, you need to understand what percentage means. 10% of $400 is $40 and since 30% is 3 times as much, you should donate $120.

To solve this problem, you first need to understand what 10% of a quantity means. 10% of a quantity is simply that quantity divided by 10. If you want to donate 30% of the $400 earned at your yard sale to charity, you first need to find 10% of $400, which is $400 divided by 10. This gives you $40.

Since 30% is the same as three times 10%, you just need to multiply your answer for 10% by 3. Therefore, you should donate $40 times 3, which equals $120.

We can use the base formula: [tex]a_n=a_1+(n-1)d[/tex]

[tex]a_n[/tex] = nth term

[tex]a_1[/tex] = first term

[tex]n[/tex] = position of the term

[tex]d[/tex] = common difference

First, lets find the common difference of the sequence.

12 - 5 = 7

19 - 12 = 7

26 - 19 = 7

Second, find the variables we already know.

[tex]a_1[/tex] = 5

[tex]d[/tex] = 7

Put these values into the formula: [tex]a_n = 5+(n-1)7[/tex]

We can use this expression to solve for the fifth term.

[tex]a_5=5+(5-1)7\\a_5=5+(4)(7)\\a_5=5+28\\a_5=33[/tex]

Therefore, the answer is [tex]a_n = 5+(n-1)7[/tex]

Answer:

42ft

Step-by-step explanation:

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

So that little triangle section:

 1/2 * 2 * 3 = 1/2 * 6 = 3

Now we do the rectangle Section:

Area of a rectangle = length * width

So that rectangle is 3 * 7 = 21

If you eliminate those two shapes, you are left with a trapezoid.

Area of a trapezoid is 1/2 * (base 1 + base 2) * height

Base 1 is 3 which is the width of the rectangle.

Base 2 is the 6.

The height is the given 11 feet subtracted by the 7 feet from the length of the rectangle which is 4.

Plug all this in to the formula you get 1/2 * (6 + 3) * 4 = 1/2 * 9 * 4 = 1/2 * 36 = 18.

Now add all of your areas together;

21 + 3 + 18 = 24 + 18 = 42

Answer:

Area=42 ft.²

Step-by-step explanation:

This is an area problem. But since there are multiple shapes (2 triangles and a rectangle) we have to split the shapes and work each one separately. First we will start on the far right, with the small triangle. This one is the easiest one since the line is already drawn to separate it from the rest of the shape.

    Area of a triangle=1/2 bh

                               A=1/2(2x3)

                               A=1/2(6)

                               A=3

The next shape is the the rectangle in the middle.  Looking at the first image, I've drawn a line across the bottom, we need to find the area of that new image, the width is 3 ft and the length is 11 ft.

    Area of a rectangle=lw

                                  A=(11x3)

                                  A=33

Finally, we need to find the area of the last triangle. Looking at the second image, I've add the correct base and height, 4 and 3. So now we need to use the triangle formula and solve

    Area of a triangle=1/2bh

                               A=1/2(4x3)

                               A=1/2(12)

                               A=6

Now we can add the three areas together and get the total area:

  3+33+6=42 ft

Answer:

x + a + 2

Step-by-step explanation:

g(a) = a² + 2a

g(x) - g(a) = x² + 2x - a² - 2a

= x² - a² + 2x - 2a

= (x - a)(x + a) + 2(x - a)

= (x - a)(x + a + 2)

[g(x) - g(a)] ÷ (x - a)

= x + a + 2

Answer:

No.

Step-by-step explanation:

17+18 is not greater than 35.

17 + 18 = 35

so three sides of those lengths form a degenerate triangle, three collinear points.  A degenerate triangle is not a triangle.  The triangle inequality is not satisfied.

Answer:

540 calories

Step-by-step explanation:

We are trying to find y (calories), when x (fat) equals 35 grams.

So, we can substitute 35 in for x

y= 10x +190

y=10(35)+190

Multiply 10 and 35

y=350+190

Add 350 and 190

y=540
