Ayah akan membuat sebuah kolam ikan hias. Kolam tersebut berbentuk lingkaran dengan panjang diameter 80 cm, luas tanah yang di perlukan untuk membuat kolam adalah??​

Answers

Answer 1

Answer:

[tex]A=5024\ cm^2[/tex]

Step-by-step explanation:

Father will make an ornamental fish pond. The pool is circular with a diameter of 80 cm, the area of ​​land needed to make a pool is ??

The diameter of a circular pool, d = 80 cm

It means that,

Radius, r = d/2

r = 40 cm

We need to find the area of the land needed to make a pool. The area of a circular path is given by :

[tex]A=\pi r^2[/tex]

Put the values in the above formula.

[tex]A=3.14\times (40)^2\\\\A=5024\ cm^2[/tex]

So, it will require [tex]5024\ cm^2[/tex] area of land to make a pool.

The difference of 8 times a number and 2

Answers

Let us "translate" the words into algebra, step by step:

x = the number

Difference of a number and 2: (x - 2)

Eight times the difference of a number and 2: 8(x - 2)

The sum of the number and 3: (x + 3)

Three times the sum of the number and 3: 3(x + 3)

Eight times the difference of a number and 2 is the same as 3 times the sum of the number and 3:

8(x - 2) = 3(x + 3)

Now just solve for x.

8x - 16 = 3x + 9

5x = 25

x = 5

The number is x = 5

x=\frac{7}{-7}

answer:

x=-1

The value of x would be equal to -1.

An equation is defined as an expression that shows the relationship between two or more numbers, variables, and a mathematical equation is a statement with two equal sides and an equal sign in between.

We are given the equation as;

x + 1 + 4x = 11 + 12x - 3

Now solve for x;

x + 1 + 4x = 11 + 12x - 3

5x+1=11+12x-3

5x+1=8+12x

5x+1-12x=8

-7x = 8 - 1

-7x=7

x=-1

The solution will be -1.

6x = 3x + 8

Step 2 - Subtract 3x on both sides

6x = 3x + 8

Use the point slope form: y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

Plug in the point and slope:

y - y1 = m(x - x1)

So we know that Jordan bought 12 balls and Annika bought 16. We also know that they came is packages that each contain some number of balls. We are trying to find the greatest possible number of tennis balls in each package.

The greatest possible number of tennis balls in each package would be the greatest common factor of 12 and 16.

To find the greatest common factor of 12 and 16, lets first find all of the factors of 12 and the factors of 16.

12: 1, 2, 3, 4, 6, 12

16: 1, 2, 4, 8, 16

From looking at the factors of 12 and 16, we can find that the greatest common factor of 12 and 16 is 4. Therefore, the greatest possible number of tennis balls in each package would be 4.
