What is the fundamental principle of multiplication?If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
we have been given that the spacecraft is descending at a rate of 13.81 kilometres per minute, then change in height after 5 and 1/2 minutes will be;
WE can see that the astronaut is descending 13.81 km each minute, so multiply that by 5 and a half minutes .
Then multiply 5 and 1/2 minutes by 13.81,
Speed = distance / times
Rate = 11/2 x 13.81
Rate = 75.955
Therefore, The change in height after 5 and 1/2 minutes to the nearest kilometer will be 75.955

What is an expression?
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
2x + 4 - 5x is an expression.
3x = 4 is an expression.
We have,
We will find the value of the expression when x = 3.
2x³ = 2 x 3³ = 2 x 3 x 3 x 3 = 64
2x³ + 5 = 2 x 3³ + 4 = 64 + 4 = 68
(2x)³ = 2³ x 3³ = 8 x 27 = 216
(x - 1)³ = (3 - 1)³= 2³ = 8
We see that,
2x³ has the greatest value.

What are Parallel Lines Cut by Transversal?
Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.
Corresponding angles
When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position
Alternate Interior Angles
Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.
Alternate Exterior Angles
The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.
Consecutive Interior Angles
When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.
Given data ,
Let the angle be ∠ABC = ( 3x - 70 )°
Now , from the figure ,
The value of angle ∠A = x°
The value of x° is equal to ( 3x - 70 )° because they are corresponding angles
Now , from the theorem of angles cut by transversal , we get
The pairs of angles formed on the same side of the transversal that are either both obtuse or both acute and are called corresponding angles and are equal in size
Each pair of corresponding angles on the same side of the intersecting transversal are equal to each other
So ,
Substituting the values in the equation , we get
x° is equal to ( 3x - 70 )°
x° = ( 3x - 70 )°
x = 3x - 70
Adding 70 on both sides of the equation , we get
3x = x + 70
Subtracting x on both sides of the equation , we get
2x = 70
Divide by 2 on both sides of the equation , we get
x = 35°
So , the value of ∠ABC = ( 3x - 70 )°
∠ABC = ( 3x - 70 )°
∠ABC = ( 135 - 70 )°
∠ABC = 35°
Hence , The value of the angle ∠ABC = 35°

If f(x) = x2 + 1 and g(x) = x – 4, which value is equivalent to (f circle g) (10)? 37 97 126 606
Answer:
A. 37
Step-by-step explanation:
(fxg) (10)
Step 1. G is the second letter, so we first use the equation g(x) = x-4
Step 2. Plug in ten for x. g(x) = 10-4
Step 3. ten minus four is six. g(x) = 6
Step 4. Now the new x is 6 and we use the second equation next.
f(x) = x^2 + 1
Step 5. Plug in six for x. f(x) = 6^2 + 1
Step 6. six to the power of two is 36. f(x) = 36 + 1
Step 7. 36 plus one is 37. f(x) = 37

Action video rents dvds and video games to its customers. The cost to rent d, DVD movies, is $3.50 each and the cost to rent r, video games, is $2.50 each. Which of these represents the possible number of DVDs that could be rented for no more that $20?
Answer:
d = 5.71
Step-by-step explanation:
Let
Quantity of DVD movies = d
Quantity of Video games = r
Price of DVD movies = $3.50
Price of video games = $2.50
Total budget plan for DVD movies= $20
Which of these represents the possible number of DVDs that could be rented for no more that $20
Price of DVD movies × Quantity of DVD movies = $20
$3.50 × d = $20
3.50d = 20
Divide both sides by 3.50
d = 20/3.50
= 5.71

Step-by-step explanation:
72 flowers in 8 equal rows will have 9 flowers in each row.
__
72 = 8 × 9
Answer:
There are 9 flowers in each of the 8 rows
Step-by-step explanation:
Kevin plants a total of 72 flowers in equal rows he plants 6 rows of yellow flowers and 2 rows of red flowers how many flowers are in each row
Solution
Total flowers = 72 in Equal rows
Yellow flowers = 6 rows
Red flowers = 2 rows
Rows of yellow flowers + Rows of rec flowers = 6 + 2
= 8 rows
Flowers in each row = Total flowers / total rows
= 72 flowers / 8 rows
= 9 flowers
Flowers in each row = 9 flowers
