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

An olympic-size swimming pool is a rectangle that measures 50 meters in length and 25 meters in width. Make a scale drawing of an olympic-size swimming pool where 1 centimeter represents 5 meters. What are the length and width of your scale drawing?
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.

A crayon is 4 inches long. A wooden board is 8 feet long. Which diagram and statement best represents their lengths?
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.

A coffee shop served 24 people before 7:00am. Two-thirds had regular coffee, one-eighth had decaf, and the remaining ordered a specialty coffee. How many customers ordered a specialty coffee?
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.
What is a fraction?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.

1/5
Answer:
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.

the corners of a meadow are shown on a coordinate grid. Ethan wants to fence the meadow. What length of fencing is required?
On the grid: Point A (-6,2); Point B (2,6); Point C (7,1); Point D (3,-5)
Answer:
34.6 units
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
solve for x
-x + 1 = x + 21
Answer:
[tex]x=-10[/tex]
Step-by-step explanation:
[tex]-x+1=x+21[/tex]
Subtract 1 from both sides:
[tex]-x+1-1=x+21-1\\-x=x+20[/tex]
Subtract x from both sides:
[tex]-x-x=x+20-x\\-2x=20[/tex]
Divide both sides by -2:
[tex]\frac{-2x}{-2}=\frac{20}{-2}\\x=-10[/tex]

Solve the following equation. Show all steps.
4(3y – 6) = – 3(8 – 4y)
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.

Answer:
166°
Step-by-step explanation:
Since ∠A = ∠B,
the equation below helps to find the value of x and angle A:
7x + 40° = 3x + 112°7x - 3x = 112° - 40°4x = 72°x = 72°/4x = 18°∠A = 7*18° + 40° = 166°7x+40-180=3x+112-180
7x-3x=112-40

Solve for x: 5x + one third(3x + 6) > 14
Answer:
x > 2
Step-by-step explanation:
Given
5x + [tex]\frac{1}{3}[/tex](3x + 6) > 14 ← distribute and simplify left side
5x + x + 2 > 14
6x + 2 > 14 ( subtract 2 from both sides )
6x > 12 ( divide both sides by 6 )
x > 2
Answer: x > 2
Step-by-step explanation:
5x + 1/3(3x +6) > 14 Distribute
5x + 1x + 2 > 14 Combine like terms on the left side
6x + 2 > 14 Subtract 2 from both sides
-2 -2
6x > 12 Divde both sides by 6
x > 2

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
