The plane was flying at a height of 706.32 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 package's flight time, s for the plane's altitude, and u for the packet's initial vertical velocity since it is simply dropped.
Given: t = 12 seconds for the delivery to arrive to the ground
With t = 12 and u = 0 in the second equation of motion, we so obtain
s = 0*t + 0.5*9.81*12² = 706.32 m

The solution for x in the given expression (7 = 3x/9) is: C. 21.
What is an expression?An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.
In this exercise, you're required to describe the steps that should be taken to rearrange and solve for x. Therefore, the appropriate and required steps are listed as follows:
Multiplying both sides by 9, we have:
9 × 7 = 3x/9 × 9
63 = 3x
Dividing both sides by 3, we have:
3x/3 = 63/3
x = 21.

A ball is equipped with a speedometer and launched straight upward. The speedometer reading three seconds after launch is shown at the right; the ball is moving upward. At what approximate times would the ball be moving downward and display the following speedometer readings?
The time shown by the speedometer with speed of 10 m/s is 1 s.
The time shown by the speedometer with speed of 20 m/s is 1 s.
The time shown by the speedometer with speed of 30 m/s is 1 s.
What is the time on the Speedometer?The time read by the speedometer is given as;
t = 3 s.
The speedometer has low precision and as such we can do value approximation.
For the speedometer showing the speed 10 m/s. The time is calculated as, t = (v - u)/g
where g = 10 m/s²
t = (10 - 0)/10
t₁ = 1 seconds
For the speedometer showing the speed 20 m/s. The time is calculated as, t = (v - u)/g
where g = 10 m/s²
t = (20 - 0)/10
t₂ = 2 seconds
For the speedometer showing the speed 30 m/s. The time is calculated as, t = (v - u)/g
where g = 10 m/s²
t = (30 - 0)/10

1. One of two supplementary angles is four times the other. Find the largest angle.
144 is the largest angle in supplementary angle .
What is an example of a supplementary angle?
Angles that add up to 180 degrees are referred to as supplementary angles. For instance, the sum of angle 130° and angle 50° is 180°, hence they are supplementary angles.The pair of angles known as supplementary angles always add up to 180 degrees. The terms "supplements" for these two viewpoints describe them. The Latin terms "Supplere" and "Plere," which mean "supply" and "fill," respectively, are the source of the English word "supplementary."Let one angle = x
then other angle is four times the other = 4x
x + 4x = 180
5x = 180
x = 180/5
x = 36
smaller angle = 36
largest angle = 4x = 4 * 36 = 144

Find the perimeter of this semi-circle with diameter, d = 23cm. Give your answer rounded to 1 DP.
The perimeter of the semi-circle is 59.1 cm
In this question, we have been given the diameter if the semi-circle
d = 23 cm
We need to find the perimeter of the semi-circle.
We know that, the perimeter of the semi-circle of radius 'r' is P = πr + 2r
For diameter d = 23 cm, the radius would be,
r = 11.5 cm
So, the perimeter would be,
P = πr + 2r
P = π × 11.5 + 2 × 11.5
P = (π + 2) × 11.5
P = 59.13 cm
Therefore, the perimeter of the semi-circle is 59.1 cm

What is volume?Volume is a measurement of three-dimensional space that is occupied. It is frequently expressed mathematically using imperial or SI-derived units. Volume and the notion of length are connected.
Given Data
At t=0, Water Volume is 3,000 Litres
The volume of water in the tank equals t hours later.
As it is also stated, there is x% less water in the tank at the conclusion of every hour than there was at the beginning.
After an hour, the amount of water is equal to 3,000 - = 3,000 - 30 x
Water consumption after two hours = (3,000 - 30 x) - (3,000 - 30 x)
×= (3,000 - 30 x) (3,000 - 30 x)
Also,
= 288120
⇒300000 - 3000 x - 3000 x + 30 x²
= 288120
⇒ 30 x ² - 6,000 x + 11880= 0
When we multiply both sides by 30, we get
⇒ x² - 200 x + 396=0
reducing the quadratic equation to factors
(x -198)(x-2) = 0

Two different lines are shown below with two points given from each line. Use the slope-intercept form or point-slope form to find the equation of each line.
Line A
Points: (–5, –2), (–5, 7)
Line B
Points: (7, –5), (–2, –5)
Line A has
.
The equation of line A is
.
Line B has
.
The equation of line B is
.
We have a vertical and a horizontal lines, the equations are:
Line A: x = -5 (vertical one)
Line B: y = -5 (horizontal one)
How to find the equations of the two lines?Remember that the general linear equation in the slope-intercept form is:
y = a*x + b
Where a is the slope and b is the y-intercept.
If the line passes through the points (x₁, y₁) and (x₂, y₂) then the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
Now, line A passes through (–5, –2), (–5, 7), then the slope is:
a = (7 + 2)/(-5 + 5) = 9/0
Notice that if we divide by zero, the slope tends to infinity, so we have a vertical line.
In this case, the line A will be x = -5.
Now line B passes through points: (7, –5), (–2, –5)
Then the slope is:
a = (-5 + 5)/(-2 - 7) = 0/-9 = 0
Then the line is:
y = 0*x + b
And passes through (7, –5), then:
-5 = 0*7 + b
-5 = b
So this line is y = -5.
Concluding, we have:
Line A: x = -5
Line B: y = -5

Using a proportional relationship, the table relating the number of guests and number of tables is given by the image at the end of the answer.
How to represent a direct proportional relationship?A proportional relationship is a function in which the output variable is given by the multiplication of the input variable and the constant of proportionality represented by k, according to the equation below:
y = kx.
In the context of the problem, the variables are given as follows:
y: Number of tables.x: Number of guests.He'll have 4 tables for every 20 guests, hence the constant is given as follows:
k = 4/20 = 1/5 = 0.2.
Hence the relation is:
y = 0.2x.
For 1 table, the number of guests is:
0.2x = 1 -> x = 5.
For 8 tables, the number of guests is:
0.2x = 8 -> x = 8/0.2 = 40.
For 35 guests, the number of tables is:
y = 0.2 x 35 = 7.

Step-by-step explanation:
Taylor is struggling with literal equations. She has tried to solve the equation below for several times but still can't get the correct answer. Her steps that she used to solve for m are shown below. In which step is she making an error?
The step 3y = 80v + x is incorrect, as 3y = 80v - x is the correct step by subtraction property of equality.
In this question, we have been given Taylor is solving a literal equation (x + 3y) / 2 = 40v
We have been given her steps that she used to solve for y.
We need to find an error in the steps.
First we solve given literal equation for y.
(x + 3y) / 2 = 40v
x + 3y = 40v × 2 .................(Multiply both the sides by 2)
x + 3y = 80v
x + 3y - x = 80v - x ...................(Subtract x from both the sides)
3y = 80v - x
y = (80v - x)/3 ............(Divide each side by 3)
If we observe Taylor's steps, we can see that there's an error in the step 3y = 80v + x.
Therefore, the step 3y = 80v + x is incorrect, as 3y = 80v - x is the correct step by subtraction property of equality.
