Find the number of ways of delivering five letters to five houses so that no house gets

Using the Fundamental Counting Theorem, it is found that there are 1024 ways of delivering the letters.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:

Kiran was trying to solve the equation 3x 8 = 7x - 8. She said, "The equation has no
solutions because the constant is the same." Do you agree with Kiran? Explain your
reasoning
The statement that the equation has no solutions because the constant is the same is true
How to determine the true statement?The equation is given as:
3x - 8 = 7x- 8
Add 8 to both sides
3x - 8 + 8= 7x- 8 + 8
Evaluate the like terms
3x = 7x
Divide both sides by x
3 = 7
The above equation is false, because 3 and 7 are not equal
This means that the statement that the equation has no solutions because the constant is the same is true
Hence, I agree with Kiran

According to the slope formula, the slope of the line shown in the picture is equal to - 1 / 2. (Correct choice: C)
How to find the slope of a line shown in a graph
In this problem we should determine the slope associated to a line described on a Cartesian plane. This information can be found by knowing the coordinates of two points and substituting on the secant line formula:
m = Δy / Δx (1)
Where:
m - SlopeΔx - Change in the independent variable.Δy - Change in the dependent variable.After a quick inspection, we find that the points (0, 3) and (6, 0) lie on the line and the slope according to the secant line formula is:

Consider the line 4x + 2y = 8.
What is the slope of a line perpendicular to this line?
m1 x m2 = - 1
Rearrange 4x + 2y = 8.
4x + 2y = 8
-4x, then ÷ 2
y = - 4x + 8 / 2
y = - 2x + 4
m1 = - 2, find reciprocal of - 2, by placing 1 over the 2
So, - 2 will become - 1/2, but multiplying this gives us a positive 1. Thus, m2 = 1/2
m1 x m2 = - 1
-2 x 1/2 = - 1
That means slope perpendicular to the line
4x + 2y = 8 is y = 1/2x, where a half is the gradient/slope.
Ans: 1/2

The first 5 terms of a sequence are 2 8 14 20 26 Find the nth term
Answer: [tex]\Large\boxed{a_n=6n-4}[/tex]
Step-by-step explanation:
Given sequence
2, 8, 14, 20, 26
Determine the pattern
2 + 6 = 8
8 + 6 = 14
14 + 6 =20
20 + 6 = 26
For each term, add 6 to get the next term
Determine the type of sequence
Since it continuously adds 6, the common difference is 6, which means it is an arithmetic sequence
Given the arithmetic sequence formula
aₙ = a₁ + d (n - 1)
a₁ = 1st term of a sequenceaₙ = nth term of a sequencen = nth positiond = Common differenceSubstitute values into the formula
aₙ = (2) + (6) (n - 1)
aₙ = 2 + 6 (n - 1)
aₙ = 2 + 6n - 6
aₙ = 2 - 6 + 6n
[tex]\Large\boxed{a_n=6n-4}[/tex]
Hope this helps!! :)
Please let me know if you have any questions
Given sequence :-
2 , 8 , 14 , 20 , 26...Solution :-
We need to calculate the nth term of the given sequence.
Common difference (d) = 8 - 2 => 6First term of sequence (a) = 2We know that,
tn = a + (n - 1) dApplying the values here.
>> tn = 2 + (n - 1) 6
>> tn = 2 + (n - 1) × 6
>> tn = 2 + 6n - 6
>> tn = 6n - 4
Therefore, nth term of the sequence is (6n - 4).

28 grams of seeds cost $100 , and 14 grams of seeds cost $60. If you only have $70 and someone gives you $30 to buy 28 grams, how many grams of seeds would you give the person that gave you $30 if you paid $70?
Answer:
8.4 grams
Step-by-step explanation:
We have $70 to start and someone us another $30 for a total of $100. We pay $100 for 28 grams of seeds. If we assume the peron giving us $30 wants a fair share of the seeds, we would calculate an average cost per gram and use that to determine the grams of seeds that the $30 would have covered.
($100/28 grams) = $3.57/gram
($30/$3.57/gram) = 8.4 grams
Answer:
28 grams of seeds
Step-by-step explanation:
(This question is a little tricky)
Note that:
{28 grams of seeds = $100}
----------------------------------------
You have $70 already, and then someone gives you $30.
It means $70 + $30 = $100
So you have $100 now, you can buy 28 grams of seeds and give the person that gave you $30.

How to find the side of a right triangle?A right triangle has one of its angles as 90 degrees. The side of a right angle triangle can be found using trigonometric ratios.
Therefore, the height of the taller building is the sum of the height of the smaller building and upper part of the taller building.
tan 53 = opposite / adjacent
tan 53 = x / 10
cross multiply
x = 10 tan 53
x = 10 × 1.32704482162
x = 13.2704482162
x = 13.3 m
tan 28 = y / 10
y = 10 tan 28
y = 5.31709431661
y = 5.3
Therefore, the height of the taller building is 13.3 + 5.3 = 18.6 meters.

The value of x is 11 1/2 OR 11.5
Calculating the measure of anglesFrom the question, we are to determine the value of x
In the given diagram, we have two isosceles triangles
Since base angles of isosceles triangles are equal,
Then, each of the base angles of the isosceles triangle is 68°
Then, we can write that
m ∠2 + 68° + 68° = 180° (Sum of angles in a triangle)
From the given information,
m ∠2 = 4x - 2
Then,
4x -2 + 68° + 68° = 180°
4x = 180 - 68 - 68 +2
4x = 46
x = 46/4
x = 11 1/2 OR 11.5
Hence, the value of x is 11 1/2 OR 11.5

The answer is (2,-2).
What do we mean by translation?Each point in a figure is moved the same distance in the same direction using a type of transformation known as translation.A transformation known as a translation involves shifting each point in a figure by the same amount and in the same direction. For instance, this transformation shifts the parallelogram 3 units upward and 5 units to the right.A transformation in geometry is an action that moves, flips, or modifies a shape (referred to as the preimage) to produce a new shape (called the image). An example of a transformation is a translation, which moves every point in a figure uniformly and in one direction.Find the image of the given point under the given translation:
The rule of translation is (x+9, y - 3), P (-7, 1).
