J is between H and K If HJ=5p JK=p and KH=3 Find HJ
Answer:
HJ = 2.5
Step-by-step explanation:
It is given that, J is between H and K. So,
HK = JH + JK
We have, HJ=5p JK=p and KH=3
So,
3 = 5p + p
3 = 6p
p = 1/2
The value of p is 1/2
Put the value of p in HJ=5p
i.e.
[tex]HJ = 5\times \dfrac{1}{2}\\\\HJ=2.5[/tex]

How many times greater is 1 light year in scientific notation than a 1 astronomical unit?
Light year: 9.5 x 10^12 km
AU: 1.5 x 10^8 km
Answer:
1 light year \approx 6.02 \times 10^4 astronomical unit
Step-by-step explanation:
ratio
[tex]=\frac{9.5 \times 10^{12}}{1.5 \times 10^8}\\=\frac{19}{3} \times 10^{12-8}\\\approx 6.01666 \times 10^4 \\\approx 6.02 \times 10^4[/tex]
The number of times that 1 light year is greater than 1 astronomical unit in scientific notification is; 6.33 × 10⁴
We are given;
1 light year = 9.5 × 10^(12) km
1 astronomical unit = 1.5 × 10^(8) km
Thus to find out how many times greater 1 light year is than 1 astronomical unit in scientific notation, we will divide 1 light year by 1 astronomical unit.
This gives;
(9.5 × 10^(12))/(1.5 × 10^(8))
>> (9.5/1.5) × 10^(12 - 8)
>> 6.33 × 10⁴

Which of the following statements about rigid transformations is FALSE?
The shape and size are not preserved.
2:
In a reflection, the points on the pre-image and image are the same distance
from the line of reflection.
3:
Either the shape or the size is not preserved.
In a rotation, the points of the pre-image are always the same distance away
from the center of rotation as the corresponding points of the image.
4:
Answer:
The false statements are;
The shape and size are not preserved
3: Either the shape or the size is not preserved
Step-by-step explanation:
A rigid transformation, in mathematics, is a planar transformation, preserving, the length or linear dimensions of the original figure or pre-image. Examples of rigid translation includes, rotation, reflection, translation, and their combinations of these transformations.
Rigid transformation is one where a geometric shape in an Euclidean space is transformed such that the spatial distances between any two points is maintained
Therefore, both the shape of the figure or pre-image and its size are preserved.

. A container ship is overtaking an oil tanker on the way out of Harwich Harbor, and the first mate notices that if he starts walking from the front of the container ship when the two ships start overlapping, he reaches the back as the two ship separate. He walks at 3 km/hour. If the container ship is 100 m long, and travelling at 12 km/hour, how long is the oil tanker?
Answer:
The length of the oil tanker is 300 meters
Step-by-step explanation:
The given parameters are;
The speed with which the first mate is walking = 3 km/hour = 3,000 m/hour
The length of the container ship = 100 m
The speed with which the container ship is travelling = 12 km/hour
The time it takes the first mate to walk from the front to the back of the container, [tex]t_f[/tex] is therefore;
Time = Distance/Speed
[tex]t_f[/tex] = 100 m/(3000 m/hour) = 1/30 hour = 1/30 hour × 60 min/hour = 2 minutes
∴ [tex]t_f[/tex] the time it takes the first mate to walk from the front to the back of the container = 2 minutes
The resultant speed of the first mate relative to the ground = 12 km/hour - 3 km/hour = 9 km/hour
Given that the first mate starts at the front when the two ships starts overlapping and reaches the back as the two ships separate, we have;
The speed of the oil tanker relative to the container ship = The speed of the first mate relative to the ground
The speed of the oil tanker relative to the container ship = 9 km/hour
The length of the oil tanker = The speed of the oil tanker relative to the container ship × Time of observation of the first mate
∴ The length of the oil tanker = 9 km/hour × 2 minutes = 9 km/hour × 1/30 hours = 3/10 kilometers = 0.3 kilometers = 300 meters
The length of the oil tanker = 300 meters.
What is the value of x in the following equation? x2 - 1 = 8
Answer:
4.5
Step-by-step explanation:
if we take -1 and put it in L.H.S it becomes 8+1=9 and then when u put x2 which is x×2 to L.H.S it becomes 9÷2 =4.5
Answer:
4.5
Step-by-step explanation:
First break it apart by taking the x2 and set it aside then add 8 + 1 which is 9.
Next take the 9 and divide it by 2 then you get 4.5.
To double check make sure to multiply 4.5 by 2 just to make sure it gets 9 as the answer.

P is between A and E, AE=27.3 and AP=12.8. What is the length of PE?
The length of line PE from the distance AE is 14.5
The schematic view showing the illustration of the question is shown in the image attached below.
Given that:
line AE = 27.3line AP = 12.8Line AP shows the distance halfway to line AE.
In order to determine the value of line PE, we need to subtract the value of line AE from PE.
i.e.
AE = 27.3 - 12.8AE = 14.5Therefore, we can conclude that the length of PE is 14.5

find an ordered pair x-2y=4
The ordered pair for the equation x-2y=4 will be (-4,-4).
What is the equation?A mathematical equation is a claim that two expressions, which may contain variables or numbers, are equal. Equations are essential questions, and the main motivations for the development of mathematics have been efforts to methodically discover answers to these questions.
It is given that the equation is x-2y=4.
We have to find the ordered pair for the triangle.
You may run a test to see whether an ordered pair is a solution to an equation. Put the ordered pair's x-value into the equation after identifying it. It is clear that the ordered pair is a solution to the equation if, after simplifying, the y-value you obtain matches the y-value in the ordered pair.
The question is incomplete.
The complete question is to find the ordered pair of the equation x-2y=4 is the coordinates (-4,y)

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
12r + 5 + 3r - 5
Add like terms.
= 15r + 5 - 5
= 15r + 0
