The integer which represents the rise in temperature of 19° is -|19|
Positive, negative, and zero numbers all fall under the category of integers. The word "integer" is a Latin word that signifies "whole" or "intact." Therefore, fractions and decimals are not considered to be integers.
A number without a decimal or fractional element is known as an integer, which encompasses both positive and negative numbers, including zero. The following are some examples of integers: -5, 0, 1, 5, 8, 97, and 3,043. Z denotes a collection of integers,
hence the correct form is answered.

Given that
There is a square with its side as PQ = 2x + 8 and the perimeter is 96. And we have to find the side PQ of the square.
Explanation -
As it is a square and all the sides of the square are the same.
Since the perimeter is the sum of all the sides and its formula is given as
[tex]Perimeter\text{ of square = 4}\times side[/tex]On substituting the value we have
[tex]\begin{gathered} 96=4\times(2x+8) \\ \frac{96}{4}=2x+8 \\ 24=2x+8 \\ 2x=16 \\ x=8 \\ So,\text{ PQ = 2}\times8+8=16+8=24 \\ PQ=24 \end{gathered}[/tex]So the correct option is A.

The standard form of the quadratic equation is 6y = 5x² + 17x + 6.
What is the quadratic equation?
A quadratic equation is an equation such that there is a quadratic polynomial.
Given that the x-intercept is (-3,0). The graph passes through the point (2, 10).
Assume that the equation is y = ax² + bx + 1.
Putting x = -3 and y = 0 in y = ax² + bx + 1:
0 = a×(-3)² + b×(-3) + 1
9a - 3b + 1 = 0 ....(i)
Putting x = 2 and y = 10 in y = ax² + bx + 1:
10 = a×(2)² + b×(2) + 1
4a + 2b - 9 = 0 ....(ii)
Multiply 2 with (i) and 3 with (ii), then add them:
18a - 6b + 2 + 12a + 6b - 27 = 0
30a - 25 = 0
a = 5/6
Putting a = 5/6 in 9a - 3b + 1 = 0:
9×(5/6) - 3b + 1 = 0
15/2 - 3b + 1 = 0
17/2 = 3b
b = 17/6
Putting the value of a and b in y = ax² + bx + 1:
y = (5/6)x² + (17/6)x + 1
6y = 5x² + 17x + 6

Jennifer Lopez met her 10 cousins at a family reunion. The number of male cousins (x) is 2 less than the number of female cousins (y). How many (male,female) cousins were there? (not including Jennifer)
Answer:
Explanation:
Given that Jennifer Lopez has 10 cousins
The number of male cousins is x
The number of female cousins is y
Since x is 2 less than y, we have:
x = y + 2 ...............................................................................(1)
The total number of cousins is 10, we have:
x + y = 10 ..............................................................................(2)
Substituting equation (1) in (2)
(y + 2) + y = 10
y + y + 2 = 10
2y + 2 = 10
Subtract 2 from both sides
2y = 10 - 2
2y = 8
Divide both sides by 2
y = 8/2 = 2
Substitute the value of y into (1)
x = 2

Ursula has a cylinder and a cone that have the same height and radius. Which ratio compares the volume of the cone to the volume of the cylinder? О 1 to 3 01 to 2 O 2 to 1 O 3 to 1
Answer
The ratio of the volume of a cone to that of a cylinder is 1 to 3
Explanation
The volume of a cone is given as
Volume of a cone = ⅓πr²h
The volume of a cylinder is given as
Volume of a cylinder = πr²h
The ratio of the volume of a cone to that of a cylinder is now
Volume of a cone : Volume of a cylinder
⅓πr²h : πr²h
Divide both sides by πr²h and we have
⅓ : 1
Multiply both sides by 3 and we have

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
There are two figure is shown in figure.
Now,
In first figure;
The sum of all the interior angle in a triangle is 180°.
So, We can formulate;
⇒ (6x - 10)° + (2x + 20)° + (3x + 5)° = 180°
Solve for x as;
⇒ (6x - 10)° + (2x + 20)° + (3x + 5)° = 180°
⇒ 6x - 10 + 2x + 20 + 3x + 5 = 180°
⇒ 11x + 15 = 180
⇒ 11x = 180 - 15
⇒ 11x = 165
⇒ x = 15
Thus, The value of the variable x in first figure will be 15.
For second figure;
We can formulate by the corresponding angle of the parallel lines as;
⇒ x + 50 = 70
⇒ x = 70 - 50
⇒ x = 20
Thus, The value of the variable x in second figure will be 20.
Therefore,
The value of the variable x in first figure will be 15.
The value of the variable x in second figure will be 20.

Angle 3: 57 degrees
Now angle 2 can be found because a triangle sum of all three angles is 180 degrees
We know 2 75 degrees and 33 so we can add them
75+33=108
Now subtract from 180
180-108=72
Angle 2 is 72 degrees
we can find angle 1 by first finding the missing angle next to it in the triangle
75+40=115
180-115=65
Now we can subtract 65 from 180 to find angle 1
180-65=115
Angle 1 is 115 degrees
Next to find angle 4 we have to find the other missing angle since we already know angle 3 is 57 degrees
The missing angle we just subtract 75 from 180 since the angles are next to each other on a flat plane
180-75=105
And now we add the 2 angles we know
105+57=162
Now subtract from 180
180-162=18
Angle 4 is 18 degrees
Now angle 4 and angle 5 plus 40 degrees is equal to 180 degrees
To find angle 5 we add 40 degrees and 18
40+18
58
Now subtract from 180
180-58
122
Angle 5 is 122 degrees

in your own words state the segment addition postulate.
see the attached figure
the points A, B and C are collinear (the three points lies on the same line)
so
AC=AB+BC ------> by addition segment postulate
the total length is equal to the sum of its parts
