A) First day = x blocks
Second day = x + 2 blocks
Third day = x + 4 blocks
Fourth day = x + 4 blocks
Fifth day = x + 4 blocks
B) All possible values that Makaila could walk on the first day to reach her goal are; x ≥ 11.2
C) The fewest number of blocks she could walk on this day and still meet her goal is; 70 blocks
How to solve arithmetic sequences?A) We are told that the first day, she walks x blocks
Thus;
Second day = x + 2 blocks
Third day = x + 4 blocks
Fourth day = x + 4 blocks
Fifth day = x + 4 blocks
B) Total blocks = x + x + 2 + x + 4 + x + 4 = 5x + 14
Makaila would like to walk at least 70 blocks over the next five days. Thus, the equation is;
5x + 14 ≥ 70
Subtract 14 from both sides of this equation to get:
5x ≥ 56
Divide both sides of this equation by 5 to get:
x ≥ 11.2
C) She must walk greater than or equal to 11.2 blocks the first day to reach her goal.
assume she walks exactly 11.2 blocks the first day.
then her total walking based on the formula would be:
first day 11.2
second day 13.2
third day 15.2
fourth day 15.2
fifth day 15.2
total walked is 11.2 + 13.2 + (3 * 15.2)
this equals 24.4 + 45.6 which equals 70.0
Any number of blocks over 11.2 on the first day will result in a total greater than 70 blocks.

Suppose we want to choose 5 colors, without replacement, from 18 distinct colors.
(a) If the order of the choices does not matter, how many ways can this be done?
(b) If the order of the choices matters, how many ways can this be done?
Considering the definition of permutation and combination:
the number of ways of choosing 5 colors from 18 distinct colors (the order doesn't matter) is 8,568.the number of ways of choosing 5 colors from 18 distinct colors (the order of choices matters) is 1,028,160.Definition of PermutationPermutation is placing elements in different positions. So, permutations of m elements in n positions are called the different ways in which the m elements can be arranged occupying only the n positions.
In other words, permutations (or Permutations without repetition) are ways of grouping elements of a set in which:
take all the elements of a set.the elements of the set are not repeated.order matters.To obtain the total of ways in which m elements can be placed in n positions, the following expression is used:
[tex]mPn=\frac{m!}{(m-n)!}[/tex]
where "!" indicates the factorial of a positive integer, which is defined as the product of all natural numbers before or equal to it.
Definition of combinationCombinations of m elements taken from n to n (m≥n) are called all the possible groupings that can be made with the m elements in such a way that not all the elements enter; the order does not matter and the elements are not repeated.
To calculate the number of combinations, the following formula is applied:
[tex]C=\frac{m!}{n!(m-n)!}[/tex]
This caseIn this case, you know we want to choose 5 colors, without replacement, from 18 distinct colors. This is:
We want to choose 4 colors: n= 5The total number of distinct colors: m= 18(a) If the order of the choices is not taken into consideration, you use a combination as follow:
[tex]C=\frac{18!}{5!(18-5)!}[/tex]
Solving:
[tex]C=\frac{18!}{5!13!}[/tex]
C= 8,568
Finally, the number of ways of choosing 5 colors from 18 distinct colors (the order doesn't matter) is 8,568.
(b) If the order of the choices matters, you use a permutation as follow:
[tex]18P5=\frac{18!}{(18-5)!}[/tex]
Solving:
[tex]18P5=\frac{18!}{13!}[/tex]
18P5= 1,028,160
Finally, the number of ways of choosing 5 colors from 18 distinct colors (the order of choices matters) is 1,028,160.

For the equation
8/3=14/x
The cross product is
8*x=3*14
Solving for x
x=3×14/8

Let U = { 14, 15, 16, 17, 18, 19, 20 },
A = { 16, 17, 18, 19 }.
Use the roster method to write the set A′.
Complement of A set in roster form will be {14,15,20}.
U = { 14, 15, 16, 17, 18, 19, 20 },
A = { 16, 17, 18, 19 }.
A'= {14,15,20}
A set is mathematically represented in a straightforward way using roster notation. The elements (or members) of a set are listed in a row inside the curly brackets in the roster form. If the set contains more than one element, a comma is used in a roster notation to indicate the separation of every two elements. A list of the elements of a set, each separated by a comma, enclosed in a set of curly brackets, can be used to describe the contents of the set. Roster form is the term for this method of setting forth a set.

Step-by-step explanation:
what is the question ?
check everything that applies to the angles 1 and 2 ?
in that case :
two angles are adjacent angles, when they share a vertex and side.
so, yes, adjacent angles is true
vertical angles are angles that are opposite of each other when two lines cross.
so, no, vertical angles is false.
two angles are complementary, when they are adjacent and have combined 90°.
so, yes, complementary angles is true.
2 angles are supplementary, when they are adjacent and have combined 180°.
so, no, supplementary angles is false.
a linear pair of angles is basically the same as supplementary angles.
they are formed when two lines intersect each other (at a single point). The angles at the intersection point are linear if they are adjacent to each other, and their sum is always equal to 180°.
so, no, linear pair is false.

Antonio bought a box of cookies for $3.84.
If there are 24 cookies in the box, how much did Antonio pay per cookie?
Explain your thinking using 3-5 complete sentences.
Answer:
24 cookies in a box, and it costs 3.84. since the whole thing costs 3.84, to find the unit rate of each cookie, you need to divide the price by the amount of cookies. 3.84 divided by 24 is equal to 0.16. so the price per cookie would be 16 cents.
