What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,


Here,
The given sequence is,
0, 2, 6, 12, 20,
a0 = 0,
a1 = 2
nth term an = a(n - 1) + 2(n - 1)
For 6th term
n = 6
6th term = a(6 - 1) + 2(6 - 1)
        a6 = a5 + 10
        a6 = 20 + 10
        a6  = 30
7th term,
an = a(n -1) + 2 (n - 1)
a7 = a6 + 2*6
a7 = 30 + 12
a7 = 42

Thus, the required next two-term of the sequence is 30 and 42.

what is the area of the composite figure ? enter your answer in the box . use 3.14 for pi

Answers

Answer:

The area of the composite figure = 12.785 square units

Step-by-step explanation:

The figure composite of :

A ⇒ Rectangle with coordinates (0,0) , (0,5) , (2,5) and (2,0)

B ⇒ Rectangle with coordinates (2,0) , (2,1) , (4,1) and (4.0)

C ⇒ Quarter of a circle with coordinates (2,1) , (2,2) and (3,1)

Area of A: Length = 5 and Width =2

Area of A = Length times the width = 5*2 = 10 square units

Area of B: Length = 2 and Width =1

Area of B = Length times the width = 2*1 = 2 square units

Area of C: radius = 1

Area of C = 0.25 * pi * r² = 0.25 * 3.14 * 1² = 0.785 square units

Total Area = 10 + 2 + 0.785 = 12.785 square units

11. The perimeter of a rectangle is 60 cm. The length is four times the width. What
are the length and the width of the rectangle?

Answers

Answer:

Length = 24 cm

Width = 6 cm.

Step-by-step explanation:

The formula to compute the perimeter of a rectangle is,

[tex]Perimeter=2(length+width)[/tex]

Given:

Perimeter = 60 cm

width = w

length = 4w

Determine the value of width as follows:

[tex]Perimeter=2(length+width)\\60=2\times(4w+w)\\60=10w\\w=6[/tex]

The value of length is:

[tex]length(l)=4\times w\\l=4\times6\\l=24[/tex]

Thus, the length and the width of the rectangle are 24 cm and 6 cm respectively.

Find the equation of a line that is parallel to line g that contains (P, Q).
the coordinate plane has a line g that passes through the points (-3,2) and (0,5).

3x − y = 3P − Q
3x + y = Q − 3P
x − y = P − Q
x + y = Q − P

Answers

Correct option:

[tex]\boxed{x-y=P-Q}[/tex]

Explanation:

Given that the line we are looking for is parallel to g, then the slope of that line and g is the same, therefore:

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ (x_{1},y_{1})=(-3,2) \\ \\ (x_{2},y_{2})=(0,5) \\ \\ \\ m=\frac{5-2}{0-(-3)}=1[/tex]

So we can write the point-slope form of the equation of the line as follows:

[tex]y-y_{0}=m(x-x_{0}) \\ \\ (x_{0},y_{0})=(P,Q) \\ \\ \\ y-Q=1(x-P) \\ \\ y-Q=x-P \\ \\ \\ Arranging: \\ \\ P-Q=x-y \\ \\ \boxed{x-y=P-Q}[/tex]

How many cubic feet of concrete are needed to pour 4 cylindrical pillars 5 feet high with a diameter of 4 inches?

Answers

Answer:  1.75 cubic feet concrete is needed.

Step-by-step explanation:

Alright, lets get started.

The volume of the pillar is : [tex]\pi r^2h[/tex]

We have given the height is 5 feet.

We have given the diameter is 4 inches.

So the radius will be : [tex]\frac{4}{2}=2 \ inches[/tex]

Converting inches into feet.

The radius will be : [tex]\frac{2}{12} \ feet[/tex] [tex]= 0.167 feet[/tex]

So the volume of the cylinder will be : [tex]\pi * 0.167^2*5[/tex]

So the volume of the cylinder will be : [tex]0.4380 \ cubic \ feet[/tex]

As there are 4 pillars, so total volume will be : [tex]4*0.4380[/tex]

Rectangle 25 feet long. It has a perimeter of 130 feet. What is the area of the basement?

Answers

Final answer:

To find the area of the basement, we started with the given perimeter of 130 feet and the known length of 25 feet and solved for the missing width. Once we determined the width was 40 feet, we used the formula for the area of a rectangle (Area = length × width) to calculate that the basement's area is 1000 square feet.

Explanation:

To solve the question regarding the area of a rectangle where the length is 25 feet and the perimeter is 130 feet, we must first deduce the width of the rectangle using the perimeter formula: P = 2l + 2w (where P is the perimeter, l is the length, and w is the width). Since we know the perimeter (P) and the length (l), we can rearrange this formula to solve for the width (w).

The perimeter formula is expressed as:

130 = 2(25) + 2w

130 = 50 + 2w

2w = 130 - 50

2w = 80

w = 40 feet

Now that we have both the length and the width, we can calculate the area of the rectangle using the formula Area = length × width.

Therefore, the area of the rectangle is:

Area = 25 feet × 40 feet
Area = 1000 square feet

The sum of two numbers is 39 and their difference is 5. Which is the larger number?

Answers

Answer:

22

Step-by-step explanation:

Let x be a number

Other number = 39 -x

x - (39 - x) =5

x - 39 + x = 5

2x = 5 + 39 = 44

x = 44/2

x = 22

Other number = 39 - 22 = 17

Answer:

The larger number = 22

Step-by-step explanation:

Let the two number x and y

The sum of two numbers is 39 can be represented as:

x + y = 39----------------1

The difference of two numbers is 5 can be represented as:

x - y = 5------------------2

x + y = 39----------------1

x - y = 5------------------2

Using Elimination Method and subtracting 2 from 1

x-x + y-(-y) = 39 - 5

0+y+y=34

2y=34

y=34/2

y=17

substituting y=17 in 1

x+17=39

x=39-17

x=22

The larger number = 22

A circle and a square each have a perimeter of 160 feet. Which has the greater area and by how much

Answers

Answer:

[tex]The \: circle \: has \: a \: bigger \: area \: by \approx 438 \: {ft}^{2} [/tex]

Explanation:

[tex]Diameter \: of \: circle:160 \div 3.14 \approx 51 \: ft \\ Area \: of \: circle : \frac{3.14 \times {51}^{2} }{4} \approx 2038 \: {ft}^{2} \\ Sides \: of \: square:160 \div 4 = 40 \: ft \\

Area \: of \: square: \: {40}^{2} = 1600 \: {ft}^{2} \\ 2038 - 1600\approx 438 \: {ft}^{2} [/tex]

Final answer:

Comparing the areas of a circle and a square with the same perimeter of 160 feet, the circle has a greater area by approximately 435.75 square feet.

Explanation:

We are comparing the areas of a circle and a square which both have a perimeter of 160 feet. For the square, since the perimeter (P) is 160 feet, each side (s) will be P/4, which gives us s = 40 feet. The area of the square (Asquare) is s², so Asquare = 40² = 1600 square feet.

For the circle, the perimeter is the circumference (C), which is 160 feet. The formula for the circumference of a circle is C = 2πr, where r is the radius. So, 160 = 2πr, giving us r = 160/(2π). The area of the circle (Acircle) is πr², so Acircle = π(160/(2π))². After calculation, we find that Acircle ≈ 2035.75 square feet.

Comparing the two areas, the circle has a greater area than the square by Acircle - Asquare ≈ 2035.75 - 1600 ≈ 435.75 square feet.

What is the value of -36÷(-4/9)

Answers

The value of -36 divided by (-4/9) is 81, which is found by multiplying -36 with the reciprocal of (-4/9), giving the result 324/4, which simplifies to 81.

To find the value of -36 divided by (-4/9), you can think of division by a fraction as multiplication by its reciprocal. So, the problem changes from division to multiplication: -36 * (-9/4). To solve this:

First, multiply the numerators: -36 * -9 = 324.

Then, multiply the denominators: 1 * 4 = 4.

Now, divide 324 by 4 to get 81.

Therefore, the value of -36 divided by (-4/9) is 81.
