Answer:using division method

Step-by-step explanation:

Example is the square root of 144

144 divided by the less prime number till 144 can not be divided again

144÷2=72

72÷2=36

36÷2=18

18÷2=9

9÷3=3

3÷3=1

Then you group the prime numbers used

(2×2)×(2×2)×(3×3)

Then take one of the prime numbers form each group

2×2×3=12

Step-by-step explanation:

The lenght of fencing required is the total distance between point A to B, B to C, C to D, and D to A. That is the distance between all 4 corners of the meadow.

The coordinates of the corners of the meadow is shown on a coordinate plane in the attachment. (See attachment below).

Let's use the distance formula to calculate the distance between the 4 corners of the meadow using their coordinates as follows:

Distance between point A(-6, 2) and point B(2, 6):

[tex] AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] A(-6, 2)) = (x_1, y_1) [/tex]

[tex] B(2, 6) = (x_2, y_2) [/tex]

[tex] AB = \sqrt{(2 - (-6))^2 + (6 - 2)^2} [/tex]

[tex] AB = \sqrt{(8)^2 + (4)^2} [/tex]

[tex] AB = \sqrt{64 + 16} = \sqrt{80} [/tex]

[tex] AB = 8.9 [/tex] (nearest tenth)

Distance between B(2, 6) and C(7, 1):

[tex] BC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] B(2, 6) = (x_1, y_1) [/tex]

[tex] C(7, 1) = (x_2, y_2) [/tex]

[tex] BC = \sqrt{(7 - 2)^2 + (1 - 6)^2} [/tex]

[tex] BC = \sqrt{(5)^2 + (-5)^2} [/tex]

[tex] BC = \sqrt{25 + 25} = \sqrt{50} [/tex]

[tex] BC = 7.1 [/tex] (nearest tenth)

Distance between C(7, 1) and D(3, -5):

[tex] CD = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] C(7, 1) = (x_1, y_1) [/tex]

[tex] D(3, -5) = (x_2, y_2) [/tex]

[tex] CD = \sqrt{(3 - 7)^2 + (-5 - 1)^2} [/tex]

[tex] CD = \sqrt{(-4)^2 + (-6)^2} [/tex]

[tex] CD = \sqrt{16 + 36} = \sqrt{52} [/tex]

[tex] CD = 7.2 [/tex] (nearest tenth)

Distance between D(3, -5) and A(-6, 2):

[tex] DA = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] D(3, -5) = (x_1, y_1) [/tex]

[tex] A(-6, 2) = (x_2, y_2) [/tex]

[tex] DA = \sqrt{(-6 - 3)^2 + (2 - (-5))^2} [/tex]

[tex] DA = \sqrt{(-9)^2 + (7)^2} [/tex]

[tex] DA = \sqrt{81 + 49} = \sqrt{130} [/tex]

[tex] DA = 11.4 [/tex] (nearest tenth)

Length of fencing required = 8.9 + 7.1 + 7.2 + 11.4 = 34.6 units

Answer:

Length: 10 cm

Width: 5 cm

Step-by-step explanation:

The required length and width of the scale drawing are given a length will be 10 cm and the width will be 5 cm.

Given that,
A swimming pool of rectangle shape that measures 50 meters in length and 25 meters in width. To make a scale drawing of an Olympic-size swimming pool where 1 centimeter represents 5 meters.

The scale factor is defined as the ratio of the modified change in length to the original length.

Here,
Given scale: 1 cm = 5 m
So, for 1 m = 1/5 cm
Now,
Length = 50 × 1/5  = 10 cm
Width = 25 × 1/5 = 5 cm

Thus, the required length and width of the scale drawing is given a length will be 10 cm and a width will be 5 cm.

[tex]x=-10[/tex]

Step-by-step explanation:

[tex]-x+1=x+21[/tex]

Subtract 1 from both sides:

Step-by-step explanation:

The wooden board is 24 times the length of Crayon which is represented by Figure C.

We have,

A crayon is 4 inches long.

A wooden board is 8 feet long.

We know that

1 feet = 12 inch

So, 8 feet = 12 x 8 = 96 inches

Now, the factor between Caron and wooden block

= 96 / 4

= 24

Thus, the wooden board is 24 times the length of Crayon which is represented by Figure C.

Answer:

5 people

Step-by-step explanation:

Regular- 2/3 times 24/1 gets you 16 people

Decaf- 1/8 times 24/1 gets you 3 people

16+3 is 19

24-19=5 people

The number of customers that ordered a specialty coffee is 5.

Fractions represent the parts of a whole or collection of objects.

A fraction has two parts. The number on the top of the line is called the numerator and the number on the top of the line is called the denominator.

Now it is given that,

Total number of customers = 24

Customers having regular coffee = Two-thirds

⇒ Number of customers having regular coffee = 2/3 * 24 = 16

Customers that had decaf = one-eight

⇒ Number of customers having decaf = 1/8 * 24 = 3

Total number of customers having regular coffee and decaf = 16 + 3 = 19

Therefore, Customers that ordered a specialty coffee = Total number of customers - Total number of customers having regular coffee and decaf

⇒ Customers that ordered a specialty coffee = 24 - 19

⇒ Customers that ordered a specialty coffee = 5

Thus, the number of customers that ordered a specialty coffee is 5.

Step-by-step explanation:

Answer:

The sum is a fraction

Step-by-step explanation:

Answer:

0=0

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4(3y−6)=−3(8−4y)

(4)(3y)+(4)(−6)=(−3)(8)+(−3)(−4y)(Distribute)

12y+−24=−24+12y

12y−24=12y−24

Step 2: Subtract 12y from both sides.

12y−24−12y=12y−24−12y

−24=−24

Step 3: Add 24 to both sides.

−24+24=−24+24

Answer:

All real numbers

Step-by-step explanation:

So we have the equation:

[tex]4(3y-6)=-3(8-4y)[/tex]

First, distribute the left side:

[tex]12y-24=-3(8-4y)[/tex]

Now, distribute the right:

[tex]12y-24=-24+12y[/tex]

Subtract 12y from both sides. Both sides cancel:

[tex]-24=-24[/tex]

This statement is true.

In other words, our solution is all real numbers.

And we're done!

1/5, 3.3%, 0.352

Step-by-step explanation:

1/5 as a decimal is 0.2

the greatest is 0.352 because it has the highest number in the tenths place.

that is why the answer is:

1/5, 3.3%, 0.352

Answer:0.352, 3.3%, 1/5

Step-by-step explanation:

0.352 is the smallest amount and 1/5 is obviously the biggest if you go from 100, 1/5 would be 20 and 3.3% would be 3.3 and then .352 would be last not even equaling 1.

Answer:

p = -7

a = 10

Step-by-step explanation:

Question 1:

Step 1: Write out equation

-22 = 12p - 2(5p + 4)

Step 2: Distribute

-22 = 12p - 10p - 8

Step 3: Combine like terms (p)

-22 = 2p - 8

Step 4: Add 8 to both sides

-14 = 2p

Step 5: Divide both sides by 2

-7 = p

Step 6: Rewrite

p = -7

Question 2:

Step 1: Write out equation

11a - (4a - 7) = 77

Step 2: Distribute

11a - 4a + 7 = 77

Step 3: Combine like terms (a)

7a + 7 = 77

Step 4: Subtract 7 on both sides

7a = 70

Step 5: Divide both sides by 7

a = 10
