The surface area of the given pyramid is equivalent to 108 square inches.
Surface area of a pyramidThe surface area of a figure is the sum of the area of the surfaces of such figure.
The given pyramid is made up of 4 triangles and a square base.
Surface area = Area of square + 4(area of triangle)
Surface area = (6 * 6) + 4(1/2 * 6 * 6)
Surface area = 36 + 4(18)
Surface area = 36 + 72
Surface area = 108 square inches
Hence the surface area of the square based pyramid is 108 square inches

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

A metal bat is dropped from a hot air balloon and strikes the ground 6 seconds later. How high was the hot air balloon?
Answers
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.

Write the steps to solve it
What is the solution
When this inequality is graphed will the limit be an open or closed circle?
When this inequality is graphed will the line have an arrow pointing to the right or to the left?
Answers
Davi needs to sell 131 cups to make at least R$500 profit , the inequality for this story is 3.82x ≥ 500 ,
In the question ,
it is given that
Davi makes R$3.82 per cup of coffee sold .
he needs to make at least R$500 profit
let the number of cups of coffee sold = x ,
the term "at least" means " ≥ " ,
So , According to the question , the inequality becomes
3.82x ≥ 500
x ≥ 130.89
x ≥ 131 .....as number of cups cannot be in decimal .
so the minimum number of cups to be sold is 131 cups.
When the inequality x ≥ 131 , will be graphed then the limit will be an closed circle as equal to sign is included in the inequality .
as when the numbers increases , it move towards right side
So, When the inequality is graphed, the line will have an arrow pointing towards the right .
Therefore , Davi needs to sell 131 cups to make at least R$500 profit ,
the inequality for this story is 3.82x ≥ 500 ,
the limit of graph will be closed circle and arrow will be pointing towards right .

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

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

Answers
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.

, then find the measure of \angle A∠A.
Answers
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°.

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]
