How many tiles measuring 20cm by 50cm are needed to completely cover a wall 4m by 8m?
320 Tiles of measuring 20cm*50cm will be needed to cover a wall 4m by 8m.
Let to cover the wall of dimension 4m * 8m completely with the tiles we need x number of tiles of size 20cm * 50 cm.
The area of wall must be that of total areas covered by tiles.
So,
Area of 1 Tile = 20cm * 50 cm = 1000sq. cm
Total Area of Tiles needed = 1000x sq.cm
Total Area of wall = 4m * 8m = 400 * 800 = 320000 sq. cm
So, We know that
Total Area of wall = Area of 1 Tile * x
320000 = 1000x
x = 320
Therefore, we can conclude that we will need 320 tiles to cover a wall of area 32sq. metres completely.

Montraie bought snacks for his team's practice. He bought a bag of popcorn for $2.45
and a 18-pack of juice bottles. The total cost before tax was $29.99. How much was
each bottle of juice?
Taxes can be paid in cash or labor and can be either direct or indirect.
Cost of juice bottle is $27.54.
What is tax?Tax compliance refers to policy actions and individual behavior aimed at ensuring that taxpayers are paying the right amount of tax at the right time and securing the correct tax allowances and tax reliefs. A tax is a mandatory financial charge or some other type of the levy imposed on a taxpayer (an individual or legal entity) by a governmental organization in order to fund government spending and the various public expenditures (regional, local, or national). Around 3000–2800 BC, the first recorded taxation was enacted in ancient Egypt. Non-compliance with the law includes failing to pay on time as well as evading or resisting taxation. Taxes can be paid in cash or labor and can be either direct or indirect.
Most nations have a tax system in place to finance public, shared, or agreed-upon national necessities as well as governmental duties. While some scale taxes are progressive based on brackets of annual income amounts, most impose a flat percentage rate of taxation on personal annual income. The majority of nations impose taxes on both personal and business income. The Wealth taxes, inheritance taxes, estate taxes, gift taxes, property taxes, sales taxes, usage taxes, payroll taxes, fees, and/or tariffs are frequently levied by nations or subunits.

Vector v = <3, 1>. Describe how you would use a graphical method to add vector v to vector u (shown in the graph below). Then, write the resultant vector in component form.
The component form of the resulting vector is <5, -4>
Vector:
Vector means the objects which have both, magnitude and direction. Magnitude defines the size of the vector. It is represented by a line with an arrow, where the length of the line is the magnitude of the vector and the arrow shows the direction.
Given,
Vector v = <3, 1>.
Here we need to find the value of u through the given graph and we have to perform the addition operation in order to find the component form of the resulting vector.
Here we have the value of vector v = <3,1>
While observing the graph we have identified as the value of vector u is,
x value = 2
y value = -5
So, the component from of vector u = <2, -5>
Now the addition of u + v is equal to,
=> u + v
=> <3,1> + <2, -5>
=> < (3 + 2) , (1 + (-5))>
=> < 5, -4>
Therefore, the component form of the resulting vector is <5, -4>.

Answer:
Draw vector v in standard position. To add v to u, shift v 2 units to the right and 5 units down so its initial point coincides with the terminal point of u. Use a dotted line to depict the shifted vector v.
Now there are three sides of a parallelogram. To complete the parallelogram, draw a dotted line from the tip of vector v in the standard position to the tip of the shifted vector v.
Finally, draw the vector represented by the diagonal of the parallelogram with its initial point at the origin. The resultant vector, u + v, is this diagonal of the parallelogram in which the two vectors, u and v, are adjacent sides. The components of u + v are <5, -4>.

Jill wants to rent a car. Rental Company A charges $40 per day plus $0.10 per mile driven. Company B charges $35 per day plus $0.15 per mile driven. After how many miles driven will the price charged by each company be the same?
Considering the definition of an equation and the way to solve it, after 100 miles driven the price charged by each company will be the same.
Definition of equationAn equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values appear in addition to certain known data.
The solution of a equation means determining the value that satisfies it. In this way, by changing the unknown to the solution, the equality must be true.
To solve an equation, keep in mind:
When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.This caseBeing "x" the number of miles driven, and knowing that:
Rental Company A charges $40 per day plus $0.10 per mile driven. → Price of company A= 40 +0.10xRental Company B charges $35 per day plus $0.15 per mile driven. → Price of company B= 35 +0.15xThe price charged by each company is the same,the equation is:
Price of company A= Price of company B
40 +0.10x= 35 +0.15x
Solving:
40 - 35= 0.15x - 0.10x
5= 0.05x
5 ÷ 0.05= x
100= x
Finally, after 100 miles driven the price charged will be the same.

Using the graph , find g (0) and find x such that g (x) =-1
In order to find g(0), we just need to find the value of the function for x = 0.
Looking at the graph, for x = 0 we have y = 7.
Therefore g(0) = 7.
To find the value of x for g(x) = -1, let's look for the value of x where y = -1.
Looking at the graph, for y = -1, we have x = -2.
Therefore g(x) = -1 for x = -2.
What is the area of the gable if it is a triangle with two sides of 81 feet that meet at a 112° angle?
The area of the gable if it is a triangle with two sides of 81 feet that meet at a 112 degrees angle is 3041.22 square feet
The two sides of the triangle=81
AB=AC=81 feet
∠A=112 degrees
∠BAD=∠DA =56 degrees
Here we have to use trigonometric functions
To find the height of the triangle we have to use the cos function
cos θ=Adjacent side/Hypotenuse
cos 56=Height/81
Height=81×cos 56
=45.29 feet
To find the length of the DC, we have to use the sine function
sin θ=Opposite side / Hypotenuse
sin 56=Base / 81
Base DC=81×sin 56
=67.15 feet
The base of the triangle BC=BD+DC
=67.15+67.15
=134.3 feets
The area of the triangle=(1/2)×b×h
Where b is the base and h is the height
=(1/2)×134.3×45.29
=3041.22 square feet
Hence, the area of the gable if it is a triangle with two sides of 81 feet that meet at a 112 degrees angle is 3041.22 square feet

Ava purchased a membership to this pizza shop. How much would Ava have to pay the pizza shop if she bought 18 slices of pizza this month? What would be the monthly cost for x slices of pizza? mx+b
The cost of 18 slices of pizza is $18.
The monthly cost for x slices of pizza is $25 + x
What is the monthly cost?The equation that represents the amount of money that Ava would have to pay when she buys 18 slices of pizza is a linear equation. A linear equation is an equation that has one variable raised to the power of one. The linear equation increases by a fixed amount. When drawn on a coordinate plane, a linear equation is a straight line.
The total monthly cost is a function of the membership fee, the cost per pizza and the number of pizzas bought.

A fraction a/b has a multiplicative inverse of b/a. Divide 1 by the real number to obtain the multiplicative inverse of the number. When a number is multiplied by its original number, the multiplicative inverse of that number, or x-1, produces a value equal to 1.
