The number of months it will take for both accounts to have the same amount of money is 250.50 - 35m = 300 - 45.25m, which can be found using the equation.
Let m be the number of months.
It is given that:
The international Business club starts with $ 250.50 in their account.
and each month they spent $ 35 on activities.
This means that after m months the total amount left in the bank account is:
250.20-35 m
The future agriculture leaders club start with a amount of $ 300 and spent $ 45.25 each month.
This means that the amount left in the account after m months is:

The values of all 3 angles are:
x = 95°y = 65°z = 115°What are angles?An angle is a figure in Euclidean geometry made up of two rays that share a common endpoint and are referred to as the angle's sides and vertex, respectively. Angles created by two rays are in the plane where the rays are located. Based on the measurement, there are different kinds of angles in geometry. The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation.So, we know that ∠AOB is s straight angle (180°).
Then,
x - 30 + x + 20 = 1802x - 10 = 1802x = 180+ 102x = 190x = 95°Now, solve for straight angle ∠DOC with x = 95°:
z + x - 30 = 180z + 95 - 30 = 180z + 65 = 180z = 180 - 65z = 115°Similarly, solve for straight angle ∠AOB with z = 115°:
z + y = 180115 + y = 180y = 180 - 115y = 65°Therefore, the values of all 3 angles are:

In 2017, one U.S. dollar was worth 19.61 Mexican pesos. How many dollars was 150.68 pesos worth?
By using unitary method, we get that 150.68 pesos are worth $ 7.6 .
What is unitary method?An individual or singular unit is referred to as unitary. Therefore, the goal of this strategy is to establish values in reference to a single unit. The unitary technique, for instance, can be used to calculate how many kilometers a car will go on one litre of gas if it travels 44 km on two litres of fuel.
We know 1 U.S. dollar = 19.61 Mexican pesos
Thus by unitary method, we get ;
1 Mexican pesos = 1 / 19.61 dollars
this implies 1 Mexican pesos = 0.5099
To find : 150.68 pesos worth
Therefore , 150.68 pesos worth = 150.68 × 0.5099
= 7.683 dollars

A manager wants to buy headsets for the customer service team members to use. the headsets cost $12 each. the budget allows $155 to be used for customer service equipment, but the manager wants to save more than $20 for later in case it is needed for something else. how many headsets can the manager buy?
Using inequality we can calculate that within the budget the manager can buy 11 headsets.
Any monotonically rising function, as long as both expression portions fall inside the scope of that specific function, can be applied to both sides of an inequality without destroying the relationship between the two.
If a monotonically falling function were applied to both ends of an inequality, the inequality relationship would be inverted.
The equations for the additive reverse and the multiplicative reverse for positive numbers are two examples of employing a monotonically decaying function.
Let the manager can buy x headsets.
Cost of x headsets = 12x
Money saved = 20
Budget = 155
Therefore we write the represented inequality as :
12x + 20 < 155
or, 12 x < 135
or, x < 11.25
Now the number of headsets can not be a decimal number, therefore 11 headsets need to be bought.
Therefore the manager can buy 11 headsets.

When two items are written inside parantheses and are separated by a comma, they create an ordered pair. For instance, the ordered pair (x, y) indicates an ordered pair in which 'x' is referred to as the first element and 'y' is referred to as the second element. These items, which can be either variables or constants, have distinct names depending on the context in which they are used. In an ordered pair, the element order is somewhat significant. It implies that (x, y) may not always be equivalent to (y, x).
In coordinate geometry, a point's location on the coordinate plane with respect to the origin is represented as an ordered pair. Two perpendicular intersecting lines, one of which is the x-axis and the other is the vertical line, together constitute a coordinate plane (y-axis).

A rectangle has a length of 14 units and a width of 6 units. Squares of x by x units are cut out of each corner, and then the sides are folded up to create an open box. Express the volume of the box as a polynomial function in terms of x.
Answer:
f(x) = 4x³ - 40x² + 84x=================================
The box is the right rectangular prism.
Its volume is the product of its three dimensions:
V = lwhWe need to find each dimension and multiply them to get the desired function.
GivenLength = 14 units,Width = 6 units,Cut = x units.SolutionThe height is same as size of the cut, so it is x units.

m∠L= ____ degrees
3. ∠Y and ∠J are vertical angles with m∠Y = 7x + 12 and m∠J = 10x − 9.
m∠J = ____ degrees
The value of m∠L is 55 degrees and the value of m∠J is 61 degrees.
As we know, vertical angles are the opposite angles made by the intersection of the two lines, vertical angles are equal in magnitude,
So, we can write,
1. ∠L and ∠Z are vertical angles,
∠L = 2x + 9 and,
∠Z = 3x - 14.
Because both are vertical angles, so,
∠L = ∠Z
2x + 9 = 3x - 14
Solving further,
3x - 2x = 9 + 14
x = 23
So, the value of ∠L is,
= 2(23)+9
= 46+9
= 55°
The value of angle ∠L is 55°,
2. As, ∠Y and ∠J are vertical angles, so they are equal,
∠Y = 7x + 12
∠J = 10x - 9
∠Y = ∠J
7x + 12 = 10x - 9
Solving further,
3x = 21
x = 7
So, the value of ∠J is,
= 10(7) - 9
= 70 - 9
= 61°
The value of ∠J is 61°.

Write an equation to model the number of movies (m) you have to watch before you earn a free movie pass. solve the equation and show your work.
Answer:
30 movies.
Step-by-step explanation:
Hey! Let's help you with your question here!
Alright, so here's what we know. When we go see a movie, we earn 2 advantage points. We need 100 points to get a free movie pass and we currently have 40 advantage points.
When writing equations like this, we need to know what the fixed values and the variable values are. The variable values are subject to change, where the fixed values, we cannot change.
In this question here, we have 40 advantage points and this is already given to us, so it cannot change. This is our fixed value. What we can change is how many times we can see a movie after that, which will earn us 2 advantage points each time. This will be our variable value.
Now that we've determined our values, let's create the formula! I will be using y to represent the total amount of points and m to represent the amount of movies seen. So, we write it as such:
[tex]y=2(m)+40[/tex]
We got our formula! Now we have to figure out how many more movies we need to watch to get our free movie pass. Since we know that is the total amount of points that we need to get, we can substitute 100 into y to solve for m which is the number of movies! It would look like this:
[tex]100=2(m)+40[/tex]
[tex]60=2(m)[/tex] - We move 40 over to the left side and subtracted 100 by 40.
[tex]\frac{60}{2}=\frac{2(m)}{2}[/tex] - We divide both sides by 2 to get rid of the 2 in front of the m.
[tex]30=m[/tex]
And there we have it! We would need to see 30 movies in order to get our free movie pass! You can double check this by taking [tex]y=2(m)+40[/tex] and substitute m with 30 and find y.
