For this case we have the following pair of numbers:
100 and 20
We must indicate the correct symbol to relationalize them. That is to say:
<,>, =
So:
[tex]100 <20[/tex]
The relationship is false.
[tex]100> 20[/tex]
The relationship is true. 100 is greater than 20.
Answer:
100 is greater than 20. The opening of the symbol should be pointing to 100. That is: [tex]100> 20[/tex]

8,000÷(28x+4)−15=25
Answer:
x = 7
Step-by-step explanation:
Order of operations rules require that we do multiplication and division BEFORE addition and subtraction.
Let's start by simplifying the expression. Adding 15 to both sides results in:
8,000÷(28x+4) = 40.
Multiplying both sides by (28x + 4) results in the simpler:
8000 = 40(28x + 4).
Dividing both sides by 40 results in:
200 = 28x + 4, or
196 = 28x
Solve for x by dividing both sides by 28:
x = 7

Answer:
x = 33
Step-by-step explanation:
There are 180 degrees in a triangle.
There are also 180 degrees in a straight line.
180 - 105 = 75.
Thus, 75+72+x=180.
x=33
Answer:
x=33
Step-by-step explanation:
Step one :
From the screen shot
The sum of angles on a straight line is 180° hence 180°-105°=75°
The unknown angle is 75°
Step two :
To find the angle x° the sum of angles in a triangle is 180°
Therefore
x°+72°+75°=180°
x+147=180
x=180-147
x=33°
Which statement above is true about the value of x
➷ Angles in a triangle equal 180 degrees
180 - (38 + 39) = 103
Angles on a straight line equal 180 degrees
180 - 103 = 77
The correct statement would be the first one as x is greater than 38

A bag contains 6 red balls, 4 green balls, and 3 blue balls. If we choose a ball, then another ball without putting the first one back in the bag, what is the probability that the first ball will be green and the second will be red?
Answer:
2/13
Step-by-step explanation:
There are 6 + 4 + 3 = 13 balls all together.
If the first one is green, this will happen with a probability of 4/13. Now there are 12 balls left
There are 6 red balls. 6/12 = 1/2
The probability of the way this happens is 1/2 * 4/13 = 2/13

What is the solution to the equation 4x-6=10x-3?
x=-2
x=-1/2
x=1/2
x=2
Answer:
x=-1/2
Step-by-step explanation:
4x-6=10x-3
Subtract 4x from each side
4x-4x-6=10x-4x-3
-6 =6x-3
Add 3 to each side
-6+3 =6x-3+3
-3 = 6x
Divide each side by 6
-3/6 = 6x/6
-1/2 =x
➷ 4x - 6 = 10x - 3
Add 3 to both sides:
4x - 3 = 10x
Subtract 4x from both sides:
- 3 = 6x
Divide both sides by 6:
x = -1/2
The correct answer would be B. x = -1/2

Which of the following equations represents a line that is parallel
Answer:
B
Step-by-step explanation:
A parallel line means equal m values, so the slope of the equation has to be 3.
Then, we can plug in the (1,6) to each of the equations with 3 as a slope and see if they are equal to each other.
B. 6 = 3 + 3
B. 6 = 6
So B is the correct equation.

Rachel has an 80:1 scale drawing of the floor plan of her house. On the floor plan, the dimensions of her rectangular living room are 1 7/8 by 2 1/2 inches. What is the area of her actual living room in square feet?
Answer:
208⅓ ft²
Step-by-step explanation:
The dimensions of Rachel's living room are 80 times the measurements on the scale drawing.
Calculate the width:
w = 80 × 1⅞
Convert the mixed number to an improper fraction = 80 × 15/8
Cancel the 8s = 10 × 15
= 150 in
Convert inches to feet = 150/12
Convert the improper fraction to a mixed number = (144 + 6)/12
= 12⁶/₁₂
Reduce the fraction to lowest terms = 12½ ft
Calculate the length
l = 80 × 2½ = 80 × 5/2 = 40 × 5 = 200 in = 200/12 = (192 + 8)/12
l = 16⁸/₁₂ = 16⅔ ft
Calculate the area
A = lw
A = 16⅔ × 12½
Convert the mixed numbers to improper fractions
A = 50/3× 25/2
Cancel the 2s
= 25/3 × 25
Multiply numerators and denominators
= 625/3
Convert the improper fraction to a mixed number
= (624 + 1)/3
= 208⅓ ft²
The area of Rachel's living room is 208⅓ ft².
The gym teacher wants to know how many students play a sport. She asks 20 students throughout the day. What is the population?
Final Answer:
The population is the total number of students in the school.
Explanation:
The gym teacher's inquiry regarding the number of students playing a sport pertains to a subset of the larger student body. In statistical terms, the 20 students she questioned represent a sample.
The population, in this context, encapsulates the entirety of students attending the school, irrespective of whether they were asked about their sports participation or not.
When the gym teacher approached 20 students throughout the day, she was essentially drawing information from a limited group within the school. The population, however, extends beyond these 20 individuals to encompass every student enrolled in the institution.
This broader set includes students who might not have been present that day or were not approached by the teacher for their input. Determining the population aids in understanding the context and scale of the sampled data.
For instance, if the gym teacher's goal is to ascertain the percentage of students engaged in sports activities, the population figure (total number of students) becomes crucial for accurate statistical inference.
Consequently, the teacher can use this information to make informed decisions or implement strategies that cater to the entire student body, considering the interests and involvement in sports across the school.

The area of a rectangle is 48 square feet. The length is 8 feet longer than the width. 1) Which picture corresponds to the problem? 2) What are the dimensions of the rectangle?
Answer:
1) The picture whose width = x and Length = (x + 8) feet
2) Width = 4 feet
Length = 12 feet
Step-by-step explanation:
A rectangle has one side longer than the other.
Area of a rectangle = product of its sides.
= length × width
Width = x feet
Length = (x + 8) feet
Area = 48
∴ x × (x + 8) = 48
x² + 8x = 48
x² + 8x + 4² = 48 + 4²
(x + 4)² = 64
x + 4 = √64
x = ±8 - 4
x = - 12 or x = 4
Since length can not be negative, x = 4
∴ Width = 4 feet
Length =4 + 8 = 12 feet
The dimensions of the rectangle where its area is 48 square feet and length is 8 feet more than width is 4 feet (width) and 12 feet (length). The question is set on algebra, calculation of area and understanding of shapes.
Explanation:This problem falls under the category of algebra and involves understanding the concept of shapes, particularly rectangles, and calculation of their area.
We know, the area of a rectangle is calculated as the product of its length and width. Given that the area is 48 square feet and the length is 8 feet more than the width. Let's denote the width as 'w' and the length as 'w + 8'.
So, we can set up the equation as: w * (w + 8) = 48. Solving this quadratic equation will give us the values for 'w' and 'w + 8' or the dimensions of the rectangle.
If you factor the quadratic equation, you get (w - 4)(w + 12) = 0. Setting these factors to zero, we find that w = 4 or w = -12. Since width cannot be negative, the width is 4 feet. And the length, which is 8 feet more than the width, will be 4 + 8 = 12 feet.
For the picture representation, simply imagine or draw a rectangle. Label the shorter side as 4 feet (width) and longer side (length) as 12 feet.

The tenth in 149.95 is 9. To round it to the nearest tenth, use the hundredth. The hundredth is 5. When rounding, always round up when it is a 5. 95 should be rounded to 100, but it is a decimal. 100 as a decimal is equal to 1. 149 + 1 = 150.
Answer:
149.95 becomes 150 when rounded to the nearest tenth because 149.95 is only .5 away from 150. If it was something like 149.4 it would be rounded to 149.

meaning it would be 15 years when your over 1,000 giving you 1,168.75
The average number of accidents is 3 per month, what is the probability of 1 accident?
The answer is: 33.33%
Why?Since we have the average number of accidents that occurs in 1 month, and it's equal to 3, we can calculate the probability of 1 accident occurs by dividing it into the average number of accidents, using the following formula:
[tex]Probability=\frac{FavorableOutcomes}{Outcomes}*100[/tex]
Where,
Favorable outcomes are the occurrence of the event, for this case, it's equal to 1.
Outcomes are the possible occurrence of the event, for this case, it's equal to 3.
So, by substituting we have:
[tex]Probability=\frac{1}{3}*100[/tex]
[tex]Probability=0.3333*100=33.33[/tex]
So, the probability will be equal to 33.33%
