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

Answer:

Step-by-step explanation:(12r+3r)+(5-5) = 15r + 0 = 15r

The simplified expression is 15r.

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.

The ordered pair for the equation x-2y=4​ will be (-4,-4).

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)

x-2y=4​

-4-2y=4

-2y=4+4

2y=-8

y= -4

Thus the ordered pair will be (-4,-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.

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.

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.
