Answer:
28.5
Step-by-step explanation:
The sum of the interior angles in a triangle is equal to 180
102 + x + 6 + x + 15 = 180
123 + 2x = 180 subtract 123 from both sides
2x = 57 divide both sides by 2
x = 28.5

The multiplication rule of counting indicates that the product of the outcomes of each event gives the total number of possible outcomes for the series of all 5 events. There are 5 outcomes for the first city, 4 outcomes for second city, 3 outcomes for the third city, 2 outcomes for the fourth city, and 1 outcome for the final city.
Write the product of the outcomes.
(first city) · (second city) · (third city) · (fourth city) · (final city)
= 5 · 4 · 3 · 2
Note that factorial notation can be used here, since we have the product of consecutive decreasing counting numbers.
Recall that
n! = n(n − 1)(n − 2) 1.
Here,
n = 5
and
5! = 5 · 4 · 3 · 2
Step 3
Multiply to find the total number of possible outcomes.
5! = 5 · 4 · 3 · 2 · 1
= ?
So by the multiplication rule of counting, the sales representative has different choices for the order in which to visit the cities.

Answer this please. I need it done in 5 minutes ASAP. Thank you
Answers
Answer:
x = 6
Step-by-step explanation:
Each side of the triangle = x cm
Each side of the square = (x - 1.5) cm
Given that the perimeter of both shapes are equal, thus, set the perimeter of the triangle equal to the perimeter of the square to solve for x.
Perimeter of triangle = 3(x) = 3x cm
Perimeter of square = 4(x - 1.5) = 4x - 6
Therefore:
Perimeter of triangle = perimeter of square
Substitute
3x = 4x - 6
Subtract 4x from each side
3x - 4x = -6
-x = -6
Divide both sides by -1
x = -6/-1
x = 6

in the form bm.
Answers
Answer: M equals 7. So it would be b^7. When you multiply exponents you add them. When you divided them you subtract
Step-by-step explanation:
The equivalent expression will be b⁵.
What is an expression?Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc.
Given an expression b¹⁰/b⁵,
We need to find an equivalent expression for the same,
So,
Using the identity,
mᵃ ÷ mᵇ = mᵃ ÷ mᵇ
= m⁽ᵃ⁻ᵇ⁾
Therefore,
b¹⁰/b⁵ = b⁽¹⁰⁻⁵⁾
= b⁵
Hence, the equivalent expression will be b⁵.

Hilbert’s hotel has rooms numbered 1, 2, 3, 4, 5, . . . – one room for each positive integer. Guests are sometimes asked to move rooms, but never more than once a day. Guests are never asked to share a room with anyone else, and guests are never turned away. Guests often arrive to Hilbert’s hotel in one of his special buses. Each bus holds passengers numbered 1, 2, 3, 4, 5, . . . – one passenger for each positive integer. 1. Our story opens with Hilbert’s hotel empty. A bus full of guests arrive at Hilbert’s hotel. (a) How can Hilbert assign people to rooms?
Answers
Answer:
For every even numbered room an even numbered guest is assigned to it and for every odd numbered room an odd numbered guest is assigned to it
Step-by-step explanation:
Given that the Hotel is empty and every passenger stands for each positive integer and each number of room represents positive numbers as well
Hilbert can assign people to rooms by using a plot of first come first serve

What are the dimensions of this rectangle?
Dimensions:
. by
Answers
Answer:
l = 4a and b = 3a
Step-by-step explanation:
Given that,
The area of the rectangle, A = 12a²
Perimeter, P = 14a
The area and perimeter of a rectangle are given by :
A = lb
12a² = lb ....(1)
P = 2(l+b)
14a = 2(l+b) ....(2)
We need to solve equations (1) and (2). After solving we find that.
l = 4a and b = 3a
Hence, the dimensions of this rectangle are 4a and 3a.
