The number of students in Regan's class will be 26.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Regan's class is preparing for a field trip. Her teacher purchased bottled water for the journey and asked Regan to stock a cooler with 2 bottles for every student who is going, 3 of the students didn't turn in permission slips and aren't going on the trip. So, Regan stocks the cooler with 46 bottles of water.
The number of students:-
46 / 2 = 23
23 + 3 = 26
Therefore, the number of students in Regan's class will be 26.

The measure of an angle is 6 greater than half the measure of it’s supplement. Find the measure of the angle
Answer:
64°
Step-by-step explanation:
Set the measure of the original angle as x.
The measure of its supplement would be 180-x.
Thus,
x = 0.5 * (180-x) + 6
x = 90 - 0.5x + 6
1.5x = 96
x = 64°
The measure of angle is 64 degree.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
The measure of an angle is 6 greater than half the measure of it’s supplement.
let the angle be x
supplement of x= 180- x
and, 6 greater than half the measure of it’s supplement.
x = 6 + 1/2( 180- x)
x= 6 + 90 - x/2
x+ x/2 = 96
3x/2 = 96
x= 32 x 2
x= 64
Hence, the measure of angle is 64 degree.

Answer:
Tan 0 = 21/29
Step-by-step explanation:
Use the identity sin(2θ) = 2sin(θ)cos(θ)
You have sin(θ) = 20/29
Given that θ is acute (meaning it's in the first quadrant), and, the opposite side is 20 and the hypotenuse is 29, you can calculate the adjacent side with the Pythagorean Theorem as 21. That means the cos(θ) = 21/29.
So sin(2θ) = 2(20/29) = (21/29)
What's the difference between a ball and a sphere?
A sphere is a two-dimensional surface embedded in three-dimensional space, while a ball is the interior of a sphere (which may or may not include the sphere itself).
A sphere and ball of radius r centered at the origin are respectively described by the equation and inequality,
x² + y² + z² = r²
and
x² + y² + z² < r²
