Dylan needs $ 21.45 for the purchase of both books and the magazine.
Addition refers to the basic operation of mathematics where we find the sum of two or moe numbers.
We are given that:
Dylan wants to buy two things:
1. she wants to buy a book for $ 16.95
2. she wants to buy a magazine for $ 4.50
So, the total money that she needs will be calculated by adding the prices of both the products.
So, by using addition, we get the total money required by Dylan as:
Total money = $ 16.95 + $ 4.50
Total money = $ 21.45
Therefore, we get that, Dylan needs $ 21.45 for the purchase of both books and the magazine.

A supermarket wants to send codes for $0.25 off a bag of chips to its rewards program members. Each coupon code will have one digit followed by four letters. The letters D and E and the digits 0, 5, and 8 will not be used. So, there are 24 letters and 7 digits that will be used. Assume that the letters can be repeated. How many such coupon codes can be generated?
Using the Fundamental Counting Theorem, it is found that 2,322,432 codes can be generated.
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:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
Considering that the ode will have one digit followed by four letters, the parameters are given as follows:
[tex]n_1 = 7, n_2 = n_3 = n_4 = n_5 = 24[/tex]
Hence the number of codes that can be generated is:
N = 7 x 24 x 24 x 24 x 24 = 2,322,432.

he mean life of a tire is 30,000 km. The standard deviation is 2000 km.
Then, 68% of all tires will have a life between ___________ km and __________ km.
The conclusion is that 68% of all tires will have a life between 28000 km and 32000 km.
How to use the Empirical Rule of statistics?
The empirical rule in statistics states that for a normal distribution,
68% of the distribution are within one standard deviation from the mean.95% are within two standard deviation from the mean.99.7% are within three standard deviations from the mean.We are given;
Mean (μ) = 30000 km
Standard deviation (σ) = 2000 km
Using the empirical rule of 68% which lies within one standard deviation from the mean, we have;
μ ± σ = 30000 ± 2000 = (28000, 32000)
Thus, we conclude that 68% of all tires will have a life between 28000 km and 32000 km.

Function yes or no what is the domain and range
Step-by-step explanation:
I assume the grid units are single units (1, 2, 3, ...).
to be a function every value of x must have exactly one value of y.
but that is violated at x = 2. at that point y can be either +3 or -3 (indicated by the 2 points at x=2).
so, no, it is not a function.
the domain is the interval or set of all valid x (input) values.
since we have no continuous curve but single points, it is a set :
x € {-4, -3, -2, 1, 2, 3, 6}
the range is the interval or set of all valid y (function result) values. again, it is a set for the same reasons :
y € {-3, -2, 0, 1, 3, 4}

Question is based on the Pythagorean theorem :
Pythagoras' theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°. The sides of a right triangle (say a, b and c) which have positive integer values, when squared, are put into an equation, also called a Pythagorean triple
Consider the triangle given above:
Where “a” is the perpendicular,
“b” is the base,
“c” is the hypotenuse.
According to the definition, the Pythagoras Theorem formula is given as:
X is the side opposite to the right angle, hence it is a hypotenuse.
Now, by the theorem we know;
Hypotenuse2 = Base2 + Perpendicular2
x2 =[tex]4^{2} +3^{2}[/tex]
x2 = 16+9
x = [tex]\sqrt{25}[/tex]

By inductive reasoning we can say that the conclusion is based on observing the four numbers in the sequence.
How to use Inductive Reasoning?
We are given the arithmetic series as;
5, 10, 15, 20, .......
From the formula of the nth term of an arithmetic series, we know that;
a_n = a + (n - 1)d
where;
a is first term
n is position of term
d is common difference
Thus, for this series, it is clear that the common difference is 5. Thus the fifth term is;
a_5 = 5 + (5 - 1)5
a_5 = 5 + 20
a_5 = 25
Thus, by inductive reasoning we can say that the conclusion is based on observing the four numbers in the sequence.

A. 10B. 12C. 4E. 72.) A rectangular garden is 6 ft longer than it is wide. Its area is 352 ft2. What are its dimensions?
Answer:
Length = 22, Width = 16
Step-by-step explanation:
Let L be the length of the garden and W the width
The area, A = L x W = 352 ft²
It is given that L = W + 6
Substituting for L in the area equation we get
L x W
==> (W + 6) x W = 352
Expanding the brackets
==> W.W + 6.W = 352
==> W² + 6W = 352
Subtract 352 from both sides:
W² + 6W - 352 = 0
This is a quadratic equation which can be solved using the quadratic formula.
- 352 = - 16 x 22 and -16 + 22 = 6
So we can factor the quadratic equation as
(W - 16) (W + 22) = 0
==> W = 16 or W = -22
Since we can disregard negative values in this context,
W = 16 and L = W + 6 = 16 + 6 = 22
Dimensions are Length = 22, Width = 16

a. What is the difference between the highest and lowest points of the country?
The difference between the highest and the lowest points of the country is 5771 feet.
What is subtraction?The operation of subtraction is used to calculate the difference between two numbers. If you have an object group and remove a couple of them, the object group gets smaller.
The process of subtracting one number from another is called subtraction. The way to calculate the difference between two numbers is by using the basic arithmetic operation of subtraction, which is represented by the symbol (-).
Let the sea level be x.
The highest point of the country is 5,762 feet above the sea. So, we can write it as
x+5,762
Since the lowest point is 9 feet below sea level, we can write this expression:
x-9
The difference is the result of subtraction. Therefore, we can find the expression that represents the difference between the elevations by subtracting x+5,762 and x-9:
(x+5,762)-(x-9)
= x+5762-x+9
= 5762+9

The image of D (1, 2) is D' ( 2, 7).
The image of E (-3 -5) is E' ( -10, 0).
The image of F (4, -1) is F' ( 11, 4).
What is Coordinates?
A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given points are;
D (1, 2), E(-3, -5) and F(4, -1)
Now, The rule is to find the image of points is;
(x, y) → (3x - 1, y + 5)
Hence,
The image of D (1, 2) = (3 * 1 - 1, 2 + 5)
= (3-1, 7)
= (2, 7)
The image of E (-3 -5) = (3*-3 - 1, -5 + 5)
= (-9-1, 0)
= (-10, 0)
The image of F (4, -1) = (3*4 - 1, -1 + 5)
= (12-1, 4)
= ( 11, 4 )
Therefore, The image of D (1, 2) is D' ( 2, 7).
The image of E (-3 -5) is E' ( -10, 0).
The image of F (4, -1) is F' ( 11, 4).

Answer: ok here is ur answer The cost for 1 chair is $2.75 and the cost for 1 table is $8.75
Use the elimination method of linear equations to find your answer.
Our equations for this problem are:
3c+5t=52 and 9c+7t=86
1. Multiply the entire first equation by -3.
-3(3c+5t=52)
2. Simplify the equation from above:
-9c-15t=-156
3. Stack the two equations on top of each other and add/subtract:
-9c-15t=-156
9c+7t=86
4. You should be left with -8t=-70. Simplify this to find the value of t:
t=8.75
5. Plug the value of t into any of the original equations and solve for c.
3c+5(8.75)=52
6. Simplify the equation above:
3c+43.75=52
7. Subtract 43.75 from both sides of the equation:
3c=8.25
8. Divide both sides by 3 to get your c value:
c=2.75
