The no. of regular tube costing $15 were 12 and the cooler tube costing $7.5 each were 24
What is a tubing?The entire family can participate in tubing. Change into swimwear, rent a tube and a life jacket, and float down the river—that it's easy. Numerous outfitters provide transportation to the best waterways and rent tubes from Blue Ridge to Columbus, via Helen and Columbus.
The total cost of rent on tube = $360
Price of regular tube = $15
Price of cooler tubes = $7.5
Let the no. of regular tubes be and cooler tubes be y
The equation forms
15x + 7.5y = 360 ...1
As we can notice regular tube is twice the price of cooler tubes, sthe the equation forms
2(7.5) = 15
This means when y = 2, x = 1
cross multiply them and we find
2/y = 1/x
x/y = 1/2
x = y/2 ...2
Putting the value of x in eq 1, we get
15(y)/2 + 7.5y = 360
7.5y + 7.5y = 370
15y = 360
y = 360/15
y = 24
Putting the value of y in eq 1, we get
15x + 7.5(24) = 360
15x + 180 = 360
15x = 360 - 180
15x = 180
x = 180/15
x = 12
Thus, The no. of regular tube costing $15 were 12 and the cooler tube costing $7.5 each were 24.

Rate of change (m) = 10
Starting amount (b) = 14
It takes 9 days to have 104 boondins.
The equation in slope-intercept form is: y = 10x + 14
Its graph is shown below.
How to Write the Equation of a Line?Where m represents the rate of change and b represents the y-intercept or starting value, the equation of a line can be written in slope-intercept form as:
y = mx + b.
From the information given, the following are given about the line:
x = number of days
y = total number of boondins
If he had 74 boondins in 6 days and he bought 10 more every day, then:
x = 6
y = 74
Starting value (b) = ?
Rate of change (m) = 10
Substitute the values into y = mx + b to find the value of b:
74 = 10(6) + b
74 = 60 + b
74 - 60 = 60 + b - 60
14 = b
b = 14
Therefore:
Rate of change (m) = 10
Starting amount (b) = 14
To write the equation in slope-intercept form, substitute b = 14 and m = 10 into y = mx + b:
y = 10x + 14
To find how many days it takes to have 104 boondins, substitute y = 104 into the equation, y = 10x + 14:
104 = 10x + 14
Solve for x
104 - 14 = 10x
90 = 10x
90/10 = 10x/10
9 = x
x = 9
It takes 9 days.
For 10 days, it would take:
y = 10(10) + 14
y = 114 boondins
The table is:
(x, y)
(0, 14)
(10, 114)
The graph for y = 10x + 14 is given in the attachment.

What is an angle?
An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle. Angles created by two rays are located in the plane containing them. Angles are also generated when two planes meet. These are known as dihedral angles. An angle defined by two intersecting curves is the angle of the rays lying tangent to the respective curves at their point of junction.

50 pound in yen is 7200 yen
What is basic algebra ?Algebra is a branch of mathematics that helps translate real-world situations or problems into mathematical truths. Mathematical operations like addition, subtraction, multiplication, and division are needed in addition to variables like x, y, and z to construct a meaningful mathematical expression. All branches of mathematics, such as calculus, trigonometry, and coordinate geometry, employ algebra. A fundamental algebraic equation is 2x + 4 = 8. Algebraic expressions serve as the mathematical statement when operations such as addition, subtraction, multiplication, division, etc. are done on variables and constants. Let's imagine that while playing with matchsticks, James and Natalie came up with the idea to arrange the sticks into designs that represented numbers.
Given that : 1 euro is 120 yen and 1 pound is 1.2 euro
1 euro = 120 yen
1 pound = 1.2 euro
1 pound = 1.2 × 120 yen
1 pound = 144 yen
50 pound = 144 ×50
= 7200 yen
50 pound in yen is 7200 yen

The slope of the given points is equal to -5/2 or -2.5.
What is a slope?A slope is also referred to as gradient and it's typically used to describe both the direction, ratio, and steepness of the function of a straight line based on its coordinates or points.
How to calculate the slope of a line?Mathematically, the slope of any straight line can be calculated by using this formula;
[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]
For the given points P(-6, 16) and Q(2, -4), the slope is given by;
Slope = Δy/Δx
Slope = (-4 - 16)/(2 - (-6))
Slope = (-4 - 16)/(2 + 6)
Slope = -20/8
Slope = -5/2 or -2.5.
For the given points R(-6, 14) and S(-2, 4), the slope is given by;
Slope = Δy/Δx
Slope = (4 - 14)/(-2 - (-6))
Slope = (4 - 14)/(-2 + 6)
Slope = -10/4
Slope = -5/2 or -2.5.

The number of cans each guest must bring to reach the goal must be greater than or equal to 5 by inequality.
What is inequality in math?
In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.Let
x -----> the number of cans each guest must bring to meet the goal
we know that
The number of guests multiplied by the the number of cans each guest must bring to meet the goal plus the currently cans must be greater than or equal to 1,000 cans
so
The inequality that represent this problem is
565 + 87x ≥ 1000
Solve for x
565 + 87x ≥ 1000
Subtract 565 both sides
87x ≥ 1000 - 565
87 ≥ 435
Divide by 87 both sides
x ≥ 435/87
x≥ 5
therefore, The number of cans each guest must bring to reach the goal must be greater than or equal to 5.

A chocolate power bar has 4 grams of fat, 23 grams of protein, and 45 grams of carbohydrates. How many Calories does this Power bar provide?
Answer:
308 Calories are provided by the Powerbar.
Step-by-step explanation:
Use the typical amounts shown for each nutrient first to calculate how many calories each one provides:
Fat: 4 grams x 9 kcal/gram = 36 kcals.
Protein: 23 grams x 4 kcal/gram = 92 kcals.
45 grams x 4 kcal/gram of carbohydrates equals 180 kcal.
To determine the total calories, add up all the Calories from each nutrient as follows:
92 calories from protein and 36 calories from fat equal 308 calories.
The Powerbar contains 308 calories.
Answer:
Total Calories = (4*9) + (23*4) + (45*4)
36+92+180 = 308 Calories
To calculate total calories we first need to convert total fat, protein, and carbohydrates into calories
1 gram of protein = 4 calories
1 gram of fat = 9 calories
1 gram of carbohydrates = 4 calories

Write an equation for a line that passes through (0, 0) and is parallel to a line that passes through (-5, 3) and (2, 1).
An equation for a line that passes through (0, 0) and is parallel to a line that passes through (-5, 3) and (2, 1) is 0 = (-2/7)0 + 0
What is a parallel line?Two or more lines that never intersect are said to be parallel. We can see parallel lines all around us, such as in the bookcase's shelves and the two sides of this page.
There is a good chance that lines or structures that appear to run in the same direction, never cross one another, and always have the same spacing between them are parallel.
We will find the slope using the slope formula that is
⇒ m = (y₂ - y₁)/(x₂ - x₁)
Given points are (-5, 3) and (2, 1), so
⇒ m = (1 - 3)/(2 - (-5))
⇒ m = -2/7
We have asked to write an equation for a parallel line that passes through (-5, 3) and (2, 1).
for a two lines to be parallel, m = m for both lines
so as the slope is (-2/7), lets put the value in (0,0)
y = mx + b
0 = (-2/7)0 + b
b = 0

The equation with solution zero are : b. 2 (x + 6) = 3 (x + 4) and d. 3x + 8 = 2x+8.
Here in this problem, we are dealing with linear equations which is a condition of one variable regularly composed within the form ax+b=0 where a and b are real numbers and x is an unknown variable. Solutions to linear equations is refer to a linear equation that can have zero, one, or infinitely numerous solutions.
