Which of the following inequalities is not true?
-22 < 3
|-1| ≥ 0
|-9| ≠ |9|
-7 ≤ -5
Answer:
ccccccccccccccccccccc
Step-by-step explanation:
The false statement is |-9| ≠ |9|.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
For example, In the 12U Softball division, Olivia gets chosen. What is Olivia's age? Olivia's age is unknown to you because the word "equals" is missing. However, since you are aware that she should be under or equal to 12, you can write Olivia's Age ≤ 12. This is a real-world example of an inequality.
Given:
-22 < 3 is true.
|-1| ≥ 0
It is true because |-1| is +1. which is greater than 0.
|-9| ≠ |9|
It is false because |-9| = +9 and |9|= 9 which are equal.
-7 ≤ -5
It is true because the smaller the small the negative number the greater its value.

FCD=x+41, BCF=x+78, BCD=95. Find x
To find x in a geometry problem involving angle measures BCD, BCF, and FCD.
The given information:
- B = 77.08795270
- C₁ = -7.062084 257
- D₁ = -0.6291204730 E₁ -14.17590540 F₁-62.91204730
Step-by-step solution:
Express BCD as a combination of the other angles: BCD = BCF + FCD. Substitute the given values: 95 = (x + 78) + (x + 41).
Simplify the equation: 95 = 2x + 119.
Solve for x: 2x = 95 - 119 = -24, x = -12.
ABCD is a square. What is the measure of angle BAC? °
Answer:
∠BAC = 45° is the measure.
Step-by-step explanation:
In a square all sides are equal and all the angles are 90°.
We have to measure the angle BAC.
since both the sides AB and BC of the triangle BAC are equal. Therefore angles opposite to these sides ∠BAC and ∠ACB will be equal.
Since ∠BAC + ∠ACB + 90° = 180° ( Sum of all angles of ΔABC = 180°)
∠BAC + ∠BAC + 90° = 180°(∠BAC = ∠ACB)
2∠BAC = 180 -90 = 90°
∠BAC = 90/2 = 45°
∠BAC = 45° is the answer.

a baker orders 162 eggs. each carton contains 18 eggs. which equation can you use to find the number x of cartons? explain your reasoning and sold the equation.
To solve for the number of cartons the baker needs, divide the total number of eggs by the eggs in each carton. This gives the equation x = 162 ÷ 18. Solve the equation to find that the baker needs 9 cartons.
Explanation:The subject of this question is mathematics, specifically division. When a baker orders 162 eggs and each carton contains 18 eggs, to find out how many cartons (represented by x) the baker needs, we would need to divide the total number of eggs by the number of eggs in each carton. This gives us the equation:
x = 162 ÷ 18
Solving this equation, we find that x equals 9. Therefore, the baker needs to order 9 cartons of eggs.

108 centimeters 1.08 meters equation and exponent
To convert 108 centimeters to meters, divide by 100, since 100 centimeters equals 1 meter. Thus, 108 cm equals 1.08 meters, and the exponential form of 1.08 is 1.08 x 10⁰.
To convert 108 centimeters to meters, we use the fact that 100 centimeters is equal to 1 meter. If we have 108 centimeters and we want to express that in meters, we divide 108 by 100, since there are 100 centimeters in a meter.
Thus, 108 centimeters is equivalent to 1.08 meters. When we write 1.08 as an exponent, we express it as 1.08 imes 100, because any number to the power of 0 is 1, and thus the exponent does not change the value of 1.08.

A theater manager is planning an upcoming concert. Regular tickets will cost $12 and student tickets will cost $8. The theater can seat at most 200 people. The manager wants to collect at least $1000 from ticket sales.
Let x represent the number of regular tickets sold. Let y represent the number of student tickets sold.
Which inequalities are among the constraints for this situation?
Select each correct answer.
12x+8y≤1000
12x+8y≥1000
x+y≥1000
x+y≤200
x+y≥200

Answer:
Option B and Option D is correct.
The inequalities are among the constraints for the given situation is,
[tex]12x+8y\geq 1000[/tex] and [tex]x+y\leq 200[/tex]
Explanation:
Let x represents the number of regular ticket sold.
and y represents the number of student ticket sold.
then, 12x represents the regular tickets at $12 each,
and 8y represents the student tickets at $8 each.
As the manager wants to collect at least $ 1000 from the ticket sale or we can say that the manager wants $ 1000 or more from the ticket sale.
then, we have the inequalities for this;
[tex]12x+8y\geq 1000[/tex]
As, the theater can seat at most 200 people or we can also say that the theater can seat 200 or less people .
therefore, the inequalities for this we have;
[tex]x+y\leq 200[/tex]
Therefore, the inequalities are among the constraints for the given situation is,
[tex]12x+8y\geq 1000[/tex] and [tex]x+y\leq 200[/tex]

The shortest known adult woman is about 24 inches tall and tallest known adult woman is about 92 inches tall. Write an absolute value equation that represents the minimum and maximum heights. Use x to represent the heights.
Answer:
An absolute value equation that represents the minimum and maximum heights 24 ≤ x ≤ 92.
Step-by-step explanation:
First we have to know about the middle number. The middle number between 24 and 92 is :
[tex]\frac {(24+92)}{2}= 58.[/tex]
Now positive difference is: 58-24=34 and 92-58=34.
Thus the height of a woman x, can vary at most 34, from 58. That is the height of a woman can be 34 ft less or more than 58.
In absolute value notation this is expressed as:
x-58≤34
what this means is that:
x-58≤34 or 58-x≤34
Further solving the equation gives: |x-58|≤34 ;
24≤x≤92

find the values of x and y
Answer:
The values of [tex]x=30^{\circ}[/tex] and [tex]y=20^{\circ}[/tex].
Step-by-step explanation:
A Linear pair is a pair of adjacent angles formed when two lines intersect.
In the given figure, [tex]80^{\circ}[/tex] and [tex]4x-y[/tex] , [tex]4x-y[/tex] and [tex]x+2y+10^{\circ}[/tex] form a linear pair.
By linear pairs theorem, we have
[tex]80^{\circ}+4x-y=180^{\circ}[/tex]
[tex]4x-y+x+2y+10^{\circ}=180^{\circ}[/tex]
On solving we get,
[tex]4x-y=100^{\circ}[/tex] ....(1)
[tex]5x+y=170^{\circ}[/tex] .....(2)
Now, to solve equation (1) and (2) by simultaneously; we get [tex]x=30^{\circ}[/tex]
putting the value of x in equation 1 we get,
[tex]4x-y=100^{\circ}[/tex]
[tex]4\cdot 30^{\circ}-y=100^{\circ}[/tex]
[tex]120^{\circ}-y=100^{\circ}[/tex]
On simplify we have, [tex]y=20^{\circ}[/tex]
Therefore, the values of x and y are: [tex]30^{\circ}[/tex] and [tex]20^{\circ}[/tex]
