19.7 as a mixed number is [tex]19\frac{7}{10}[/tex].
How can a decimal be changed into a mixed number?Discover the place value of the decimal portion to change a decimal into a mixed number. The place value serves as the fraction's denominator, and the decimal portion serves as its numerator. Write the complete number first, then convert the decimal to a fraction by positioning the decimal part over the place value.Given:
Decimal number = 19.7
To convert it to a mixed number,
Remove the decimal point and add 10 in the denominator as it has one number after the decimal point.
19.7 = 197/ 10
Now divide and write it into a mixed fraction form,
= [tex]19\frac{7}{10}[/tex]

What is ruler postulateA line segment has two fixed end points in a line. The length of the line segment is the distance between two fixed points. The length can be measured by units such as centimeters, millimeters, feet or inches
The points on a line are matched one to one with the real numbers in ruler postulate. Coordinate of the point is the real number that corresponds to a point. The distance between points A and B (AB) is equal to the difference of the coordinates of A and B.
As given,
TU = 16, UV = x+4 and TV = 8x -15
TU + UV = TV
16 + x+4 = 8x -15
16 + 4 +1 5 = 8x - x
35 = 7x
x = 35/5
x= 7
We can find UV = x + 4 by substituting the value of x
= 7 +4
= 11
and TV = 8x - 15
= (8*7) - 15
=56 - 15
=41

Answer:
One half times the difference of twenty and a variable is two thirds
one half times the quantity y minus 20 equals two thirds
one half times the quantity 20 minus y equals two thirds
one half times y minus 20 equals two thirds
one half times 20 minus y equals two thirds

In mathematics, creating equations from word descriptions is referred to as a "word problem."
For example, in the question, equations are expressed in words and then rewritten in figures, which is the preferred way to write equations.
The equation is rewritten in words and solved as below.
How to write and solve the equation
Given expression is,
[tex](\frac{-1}{8}*r-5-\frac{1}{6} *r)-(\frac{-6}{8} *r+3)[/tex]
solving the equation:
= [tex](\frac{-1}{8} *r-5-\frac{1}{6} *r)-(\frac{-6}{8} *r+3)[/tex]
= [tex](\frac{-r}{8} -5-\frac{r}{6} )-(\frac{-6r}{8} +3)[/tex]
opening the parenthesis leads to change of signs as follows
= [tex]\frac{-r}{8} -5-\frac{r}{6} +\frac{6r}{8} -3[/tex]
= [tex]\frac{-r}{8} -\frac{r}{6} +\frac{6r}{8} -5-3[/tex]
= [tex]\frac{-3r-4r}{24}+\frac{6r}{8} -8[/tex]
= [tex]\frac{-7r}{24} +\frac{6r}{8} -8\\[/tex]
= [tex]\frac{-7r+18r}{24} -8[/tex]
= [tex]\frac{11r}{24} -8[/tex]
= [tex]\frac{11}{24} *r+(-8)[/tex]
Therefore the correct answer is option D which is 11 over 24 times r plus negative 8.

A heap of garbage in the shape of a cube is being compacted. Given that the volume
decreases at a rate of 2 cubic meters per minute, find the rate of change of an edge of the cube when the volume is exactly 27 cubic meters.
The rate of change of an edge of the cube is 0.074 m/min.
What is the rate of change of volume of cube?The rate at which the volume of the cube changes is calculated as follows;
dv/dt = 2 m³/min
where;
v is the volume of the cubeThe length of edge of the cube will be denoted with a, and it is related to the volume of cube in the following equation.
v = a³
a = v^¹/₃
where;
a is the length of the edgeThe change in the edge with volume;
da/dv = 1/3 (1/v)^2/3
The change in edge of the cube with time is given as;
da/dt = da/dv . dv/dt
da/dt = 1/3 (1/v)^2/3 x 2 m³/min
da/dt = 1/3 (1/27)^2/3 /m² x 2 m³/min
da/dt = 1/27 x 2 m/min
da/dt = 2/27 m/min

What is a sphere?A sphere is a geometrical object that resembles a two-dimensional circle in three dimensions. In three-dimensional space, a sphere is a collection of points that are all located at the same r-distance from a single point. The radius of the sphere is denoted by the letter r, and the given point is its center. The sphere is a three-dimensional shape that is sometimes referred to as a circle's second cousin. A sphere is a solid shape that is round, without edges. Balloons, playing balls, and even light bulbs are examples of objects with sphere shapes.So, the formula for the volume of a sphere: V = 4/3πr³
Volume is 972, then the radius will be:

∠A and \angle B∠B are vertical angles. If m\angle A=(4x-4)^{\circ}∠A=(4x−4)
∘
and m\angle B=(5x-29)^{\circ}∠B=(5x−29)
∘
, then find the measure of \angle A∠A.
The value of angle A when A and B are vertical opposite angles is 96°.
How to illustrate the information?It should be noted that vertical angles are equal. Based on the information illustrated, it should be noted that angle A = 4x - 4 and angle B = 5x - 29.
Then, we will equate the equations and this will be:
Angle A = Angle B
4x - 4 = 5x - 29
Collect like terms
5x - 4x = -4 + 39
x = 25
Since angle A = 4x - 4 = 4(25) - 4 = 100 - 4 = 96°
Angle A is 96°.

The shortest possible time is 15 minutes.
It takes 10 minutes to fry one steak - 5 minutes from each side. Two steaks can fit on a pan. What is the shortest possible time to fry 3 steaks?
If I go with the conventional way then I can fry two steaks together taking ten minutes and then I can fry the third one in another ten minutes. So total time 20 minutes.
Assuming that I have only one pan and three steaks to fry. We can even use unitary method .
I will put two steaks in the pan then after 5 minutes I will take out one steak and put the other steak while I will flip the steak which is still in the pan. So in first ten minutes I have only one steak ready. Then I will flip the newly added steak in the pan and put the half side fully cooked steak also in the pan. So in this way in the coming five minutes my other two steaks will also get cooked. Total time taken=5+5+5=15 minutes.

A metal bat is dropped from a hot air balloon and strikes the ground 6 seconds later. How high was the hot air balloon?
The balloon was flying at a height of 176.58 m .
The fundamentals of an object's motion, such as its position, velocity, or acceleration over time, are defined by kinematics equations of motion. An object's motion in one, two, and three dimensions is determined by these three equations of motion. One of three equations of motion can be used to calculate components like displacement (s), velocity (initial and final), time (t), and acceleration (a). The following are the three motion equations:
Initial formula: v = u + at
The second formula is s = ut + 0.5at2.
The third formula is v2 = u2 + 2as.
Let t stand for the duration of the metal bat's flight, s for the height at which the hot air balloon was traveling, and u for the metal bat's initial vertical velocity since it is simply dropped.
Given: The metal bat took 6 seconds to reach the ground.
With t = 12 and u = 0, the second equation of motion gives us s = 0*t + 0.5*9.81*162 = 176.58 m.
