Find the correct plugged in formula for each figure.

Answers

Answer:

[tex]Area = 40 ( 84)+ 2 *(294)[/tex]

Step-by-step explanation:

There is only one figure in the attached image and the solution (surface area) is as follows:

The shape can be sub-divided into:

1. Rectangle

Dimension: 40 by 35

2. Rectangle

Dimension: 40 by 28

3. Rectangle

Dimension: 21 by 40

4. 2 triangles

Base: 21 and Height: 28

Calculate area of each and add them up to get the surface area of the figure.

1. Rectangle

Dimension: 40 by 35

[tex]A_1 = 40 * 35[/tex]

2. Rectangle

Dimension: 40 by 28

[tex]A_2 = 40 * 28[/tex]

3. Rectangle

Dimension: 21 by 40

[tex]A_3 = 40 * 21[/tex]

4. 2 triangles

Base: 21 and Height: 28

[tex]A_4 = 2 * \frac{1}{2} * 21 * 28[/tex]

So, the area is:

[tex]Area = A_1 +...+A_4[/tex]

[tex]Area = 40 * 35 + 40 * 28 +40 * 21 + 2 * \frac{1}{2} * 21 * 28[/tex]

Factor out 40

[tex]Area = 40 ( 35 + 28 + 21 )+ 2 * \frac{1}{2} * 21 * 28[/tex]

[tex]Area = 40 ( 84)+ 2 * \frac{1}{2} * 21 * 28[/tex]

[tex]Area = 40 ( 84)+ 2 *(294)[/tex]

What is the next term in the sequence below?

648, 108, 18, 3, . . .

A. 0.5
B. 1.5
C. 1.75
D. 2.5

Answers

Answer:

To get from one term of this sequence to the next, divide by 6.

So, once we get to three, the next term will be 0.5 because 3/6 = 0.5

Let me know if this helps!

The next term or the fifth term of the geometric sequence is 0.5. The option A is the correct option.

What is geometric sequence?

Geometric sequence is the sequence in which the next term is obtained by multiplying the previous term with the same number for the whole series.

It can be given as,

[tex]a_n=ar^{n-1}[/tex]

Here, (a) is the first term of the sequence and (r) is the common ratio.

The sequence given in the problem is,

648,  108,  18,  3,  . . .  and so on.

The common ratio between the two terns is,

[tex]r=\dfrac{648}{108}=6\\r=\dfrac{108}{18}=6\\r=\dfrac{18}{3}=6\\[/tex]\

Thus, the common ratio of the geometric series is 6.

The first term is 648 and the common ratio is 6. Thus the next or fifth term of the sequence is,

[tex]a_5=(648)(\dfrac{1}{6})^{5-1}\\a_5=(648)(\dfrac{1}{6})^{4}\\a_5=0.5[/tex]

Hence, the next term or the fifth term of the geometric sequence is 0.5. The option A is the correct option.
