What are the first 4 terms in the sequence?

A(n)=2(1/3)^(n-1)

Answer:

15 and a half days

Step-by-step explanation:

Since they earn $12's each day you would do $186 divided by $12 which would be 15.5 so it would take them 15 and a half days to raise $186.

Answer:

Sorry if this is late, but I hope you understand now.

Step-by-step explanation:

It's 16 days actually, if you divide 186 divided by 12, it's 15.5 we can say, that 5 should be rounded up or down. 15.5 is a fraction of 15/5 so if we rounded it, it would be 16. That's our newer version of rounding. 5 is higher, 4 is lower. Use that to help you :) I hope you understand even though it late

Answer:

  x = 15°

Step-by-step explanation:

Same-side interior angles are supplementary.

  (4x° +12°) + 108° = 180°

  4x° = 60° . . . . . . . . . . . . . . subtract 120°

  x = 15° . . . . . . . . . . . . divide by 4

Answer: The answer is 01 - 75.

Step-by-step Explanation: 0 - 4 and 1 - 5 aren't enough. 00 - 75 is actually 76 students and that isn't what is stated in the insert so it's 01 - 75 because it accounts for all 75 students no less and no more.

1-75 is the  range needed to label the students correctly.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Given,

An education researcher is interested in comparing the learning outcomes of students who are taught a lesson using five different teaching techniques.

There are 75 students in the school who can participate in the experiment.

0 - 4 and 1 - 5 aren't enough.

0 - 75 is actually 76 students and that isn't what is stated in the insert so it's 01 - 75 because it accounts for all 75 students no less and no more.

Hence, 1-75 is the  range needed to label the students correctly.

#SPJ2

Answer: 4.34

Step-by-step explanation:

Answer:

I will do 1 2 3 and 5 for you:

Since a cube has a given length of 5, we know that all sides will be the same therefore your lengths will be the same.

There are 6 sides of a cube so,

5 x 5 = 25 area of one flat surface.

Now 25(an area of one flat surface) x 6(flat surfaces) = 150 cm for question 1

We need to find area of the two circles:

3(given radius)^2(radius being squared) x 3.14(pi)

3 x 3 = 9

9(after radius being squared) x 3.14(pi) = 28.26(area of one circle)

28.26 x 2 = 56.52 (area of 2 circles)

Now we need to find the round surface, but first we need to find circumference:

2 x 3.14 x 3 = 18.84

18.84(circumference) x 5(height) = 94.2 (area of round surface)

Now lets add all the given areas to find surface area:

56.52 + 94.2 = 150.72 cm^2 is your answer for question 2

2 x 4 = 8

8 x 2 = 16

4 x 5 = 20

20 x 2 = 40

2 x 5 = 10

10 x 2 = 20

Add all given areas:

16 + 40 + 20 = 76 cm^2 is your answer for question 3

452.16 cm^2

4 x 3.14 x 6^2

4 x 3.14 x 36 = 452.16 cm^2 is your answer for question 4

8 x 4 = 32, 32 divided by 2 = 16

since there are 4 sides,

4 x 16 = 64

Don't forget the bottom!

4x 4 = 16

Lets add the given areas:

64 + 16 = 80 for question 5

Answer:

x = 65°

y = 25°

Step-by-step explanation:

x = 180-115 which equals 65°

y = 180-(90+65) which equals 25°

Answer: 64units³

Step-by-step explanation:

The volume of a cube will be gotten by multiplying the value of its side thrice. This means that for example if the cube has a side of xcm, the volume will be:

= x × x × x

= x³

In this case, since the cube has a side of 4 units, the volume will be:

Volume of cube = 4³

Volume of cube = 4 × 4 × 4 = 64unit³

Answer:

[tex]222.312\:\mathrm{in^3}[/tex]

Step-by-step explanation:

The composite solid consists of a cylinder and a cone. Therefore, its total volume will be the sum of the volumes of the cylinder and cone:

Volume of the cone: [tex]\frac{1}{3}\cdot 2^2\cdot 3.14\cdot 8.1 =33.912[/tex]

Volume of the cylinder: [tex]2^2\cdot 3.14 \cdot 15=188.4[/tex]

Thus, the total volume of the solid is:

[tex]33.912+188.4=\boxed{222.312\:\mathrm{in^3}}[/tex]

Answer:

first one is correct and second also but in third it is incorrect and fourth is correct so C is incorrect

Answer:

C

Step-by-step explanation:

the quotient of a number means n divided by or n/

and twelve plus four, means that is the second part of the expression

n/ 12+4 would be correct instead of 12/n +4

Answer:

6

Step-by-step explanation:

Answer:

Hello, Here is your answer.

Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism. For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units.

Answer:

Step-by-step explanation:

By drawing a net, you can see each face of the prism. You can find the areas of each face and then add them together to find the total surface area.

Step-by-step explanation:

Answer:

arc AD = 138°

Step-by-step explanation:

Recall: if two inscribed angles are subtended by the same arc, the two angles are congruent or equal to each other based on the inscribed angle theorem.

<ABD and <ACD are two inscribed angles subtended by the same arc, therefore, they are equal.

Thus:

7x + 20 = 55 + 2x

Solve for x. Collect like terms

7x - 2x = 55 - 20

5x = 35

Divide both sides by 5

x = 35/5

x = 7

✔️m<ACD = ½(arc AD) (Inscribed angle theorems)

Substitute

55 + 2x = ½(arc AD)

Plug in the value of x

55 + 2(7) = ½(arc AD)

55 + 14 = ½(Arc AD)

69 = ½(Arc AD)

Multiply both sides by 2

2*69 = Arc AD

138° = arc AD

arc AD = 138°

3h<-12

Answer:

3h [tex]\geq[/tex] -12

Step-by-step explanation:

"3 multiplied by a number h" = 3h // "Is at least" = [tex]\geq[/tex] // -12 = -12

Combine these and you get 3h [tex]\geq[/tex] -12

Given:

The term is [tex]\sqrt{-80}[/tex].

To find:

The simplified form of the given term in terms of i.

Solution:

We have,

[tex]\sqrt{-80}[/tex]

It can be written as:

[tex]\sqrt{-80}=\sqrt{80\times (-1)}[/tex]

[tex]\sqrt{-80}=\sqrt{80}\times \sqrt{-1}[/tex]

[tex]\sqrt{-80}=\sqrt{16\times 5}\times i[/tex]         [tex][\because \sqrt{-1}=i][/tex]

On further simplification, we get

[tex]\sqrt{-80}=\sqrt{16}\times \sqrt{5}\times i[/tex]

[tex]\sqrt{-80}=4\times \sqrt{5}\times i[/tex]

[tex]\sqrt{-80}=4\sqrt{5}i[/tex]

Therefore, the required term is [tex]4\sqrt{5}i[/tex].
