J is between H and K If HJ=5p JK=p and KH=3 Find HJ
Answers
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
Answers
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

Simplify 12r + 5 + 3r - 5
Answers
Answer:
Step-by-step explanation:(12r+3r)+(5-5) = 15r + 0 = 15r
The simplified expression is 15r.
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
= 15r
Thus,
15r is the simplified expression.

. 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?
Answers
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.

A rectangular prism is 3 units high, 2 units wide, and 5 units long. What is its surface area
insquare units? Explain or show your reasoning.
Answers
Answer:
62 square units
Step-by-step explanation:
Surface area of a rectangular prism = 2 ( wl + hl + hw)
Where,
w = width = 2 units
h = height = 3 units
l = length = 5 units
Surface area of a rectangular prism = 2 ( wl + hl + hw)
= 2 (2*5 + 3*5 + 3*2)
= 2 (10 + 15 + 6)
= 2 (31)
= 62 square units
Surface area of the rectangular prism = 62 square units
