Step-by-step explanation:
According to your question B is answer
The inequality x ≤ 20 has 20 positive whole-number solutions. These solutions are the whole numbers from 1 to 20, inclusive.
In mathematics, a relation that makes a non-equal comparison between two numbers or other mathematical expressions is called an inequality. It is used to compare two numbers by their size on the number line most often. Following are several notations that are used to represent different types of inequalities:
a < b: a is less than b.
a > b: a is greater than b.
a ≤ b: a is less than or equal to b.
a ≥ b: a is greater than or equal to b.
a ≠ b: a is not equal to b.
Inequalities can be solved using similar methods as equations but with some additional rules. For example, when multiplying or dividing both sides of an inequality by a negative number, the direction of the inequality sign must be reversed.
According to the question, x is lesser than or equal to 20.
We have to only find the positive whole-number solutions.
Therefore, x values start from 1 and end at 20, including 1 and 20 both.
Thus, The inequality x ≤ 20 has 20 positive whole number solutions.

How would you solve this without S.A formulas
Answers
Answer:
Step-by-step explanation:
Length of the object = 4 ft
Breadth of the object = 4 ft
Height of the object = 3 ft
Volume / Area of the object = Length * Breadth * Height
= 4 * 4 * 3
= 48 ft³
Length of the cubical hole = 2 ft
Breadth of the cubical hole = 2 ft
Height of the cubical hole = 3 ft
Volume / Area of the cubical hole = Length * Breadth * Height
= 2 * 2 * 3
= 12 ft³
Remaining Area of the object = Area of the object - Area of the cubical hole
= 48 - 12 ft
= 36 ft

If the wheel has a radius of 22 centimeters and a height of 16 centimeters, how many square centimeters of the wheel does the label cover?
Answers
To find the area of the sides of the cylinder, you must find the circumference first for the length.
C = 2(pi)r
C = 2(pi)22
C = 44(pi)
Area for the sides: A = C * h
44(pi) * 16 = 704(pi) square centimeters

Area of the base is 9 square feet, the lateral face area is 27 square feet, Lateral surface area is 27 square feet and total surface area is 36 square feet.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The square has a side length of 3 ft
Area of the base is 3×3
Area of the base is 9 square feet
Now let us find the lateral face area = 2a√[(a²/4) + h²]
=2(3)√[(9/4) + 17.64]
=6√20
=27 square feet
Lateral surface area = a√(a²+4h²)
a=3, h=4.2
Lateral surface area = 3√(9+4(4.2)²)
= 3√(9+4(17.64))
3√(9+70.56
= 3√79.56
=3×9
=27 square feet
To find total surface area, we have to find the slant height by pythagoras theorem
(1.5)²+(4.2)²=l²
2.25+17.64=l²
20=l²
4.47=l
Now total surface area = a² + 2al
=3²+2(3)(4.47)
=9+26.82
=36 square feet
Hence, Area of the base is 9 square feet, the lateral face area is 27 square feet, Lateral surface area is 27 square feet and total surface area is 36 square feet.

Complete the chart in model it on the previous page. Describe and explain the relationship between the decimals for 2/6 and 4/6
Answers
Answer: The relationship between the decimals for 2/6 and 4/6 is that the decimal for 4/6 is twice the decimal for 2/6.
When we simplify 2/6, we get 1/3, which is equivalent to 0.33 as a decimal. When we simplify 4/6, we get 2/3, which is twice the value of 1/3. So the decimal for 4/6 is twice the decimal for 2/6, which means that they have a proportional relationship.

Mrs. Jones makes scented candles and wax warmers. The table shows the ratio of the number of candles to the number of wax warmers she makes.
candles: 7, 14, 21, 28, 77
wax warmers: 5, 10, 15, 20, ?
How many wax warmers will she make when she makes 77 candles?
A. 75
B. 40
C. 55
D. 69
Answers
The ratio of candles to wax warmers is 7:5, 14:10, 21:15, 28:20, 77:x.
We can simplify the ratio by dividing each side by its greatest common factor:
7:5 can be divided by 2 to get 7/2:5/2
14:10 can be divided by 2 to get 7:5
21:15 can be divided by 3 to get 7:5
28:20 can be divided by 4 to get 7:5
Therefore, the missing value must be 55, since 77:55 is the simplified version of 77:x.
So when Mrs. Jones makes 77 candles, she will make 55 wax warmers.
Answer: C. 55
