2) Solve : You and a friend go to El Super Taco after school. You order three soft tacos and two burritos and pay $11. Your friend pays $8 for four soft tacos and one burrito. How much do tacos cost? How much do burritos cost?​

Answer:

A = πx² cm²

Step-by-step explanation:

the area (A) of a circle is calculated as

A = πr² ( r is the radius)

Given circumference C = 2πx , and C is calculated as

C = 2πr , then equating gives

2πr = 2πx ( divide both sides by 2π )

r = x

Then

A = πr² = πx² cm²

The equation of line with slope 1/3 and intercept 5 is y = 1/3 x + 5.

'5 more than' means that a number is 5 units greater than the original number, using the concept of addition.

Addition (usually signified by the plus symbol +) is one of the four basic operations of arithmetic, the other three being subtraction, multiplication and division.The addition of two whole numbers results in the total amount or sum of those values combined. The example in the adjacent image shows a combination of three apples and two apples, making a total of five apples. This observation is equivalent to the mathematical expression "3 + 2 = 5" (that is, "3 plus 2 is equal to 5").

Besides counting items, addition can also be defined and executed without referring to concrete objects, using abstractions called numbers instead, such as integers, real numbers and complex numbers. Addition belongs to arithmetic, a branch of mathematics. In algebra, another area of mathematics, addition can also be performed on abstract objects such as vectors, matrices, subspaces and subgroups.

Now, let us understand the meaning.

Let the original number be x.

'5 more than a number' implies x + 5.

This means that the new number, x + 5, is greater than the original number, x, by 5 units. We also have to keep in mind, [tex]x + 5 > x[/tex].

Hence, the final meaning is 5 units greater than the original number.

The supply-demand curve after US removed tariff on imports is provided. The customer surplus is denoted by area A+B+C+D, loss in producer surplus by A and government loss in revenue by C.

When supply is equal to the demand we get the equilibrium quantity produced and equilibrium price.

The initial price P0 is less than the equilibrium price and thus there is excess demand of the product and thus there is import. When tariff is removed price again drops increasing the excess demand and thus more product is imported.

Consumer surplus is the amount the customer saves as price set by the supplier is less than the amount the consumer is ready to pay. As the customer is ready to pay at P0, the customer surplus when price drop to P1 is given by area A+B+C+D.

The loss in producer surplus is denoted by the area A. As the tariff is removed, the loss in revenue for government is denoted by the area C.

To solve the system of equations using substitution method for three variables minimum three equations are required using following steps:

1. Get the value third variable in form of other two and substitute in other two equations.

2. Now get the value of second variable in first variable and get the value of all three variables.

Let us consider three system of equations in three variable are :

x + y + z = 0   __(1)

2x + 3y + z = 2 __(2)

3x + 2y + 2z = 1  ____(3)

Get the value of z in form of x and y from (1) and substitute in (2) and (3)

z = -(x + y)

2x + 3y -(x + y) = 2

⇒x +2y = 2   __(4)

3x + 2y +2(-(x +y)) = 1

⇒3x + 2y -2x -2y =1

⇒x = 1

Now substitute in (4)

1 + 2y = 2

⇒ y = 1/2

Now substitute the value of x and y in (1)

z = - ( 1 + 1/2)

⇒z = -3/2

The measure of the angle when a cannonball is shot will be 60°.

The quantity which has magnitude, and direction, and follows the law of vector addition is called a vector.

A cannonball is shot with a speed of 90 m/s. Assuming its upward speed at the highest point of its curve is 0 m/s and the flat speed at the highest point of its bend is 45 m/s.

We know that in projectile motion, the horizontal velocity does not change.

Let 'x' be the angle it shot. Then the cosine of the angle x is the ratio of horizontal velocity to the resultant velocity when it is shot. Then we have

cos x = 45 / 90

cos x = 1/2

cos x = cos 60°

x = 60°

The correct spelling are of the following words is Caucion :caution ,Isle :aisle and Cents :sents

The scent of her perfume is the signifier, and the feminine and romantic association she makes with the scent is the signified.

In linguistics, the concepts of signifier and signified are seen in Saussure's theory of the sign. A sign is formed by the pair signifier/signified. Signifier is a word, an image, anything that has a material form. Signified is the meaning attributed to the signifier by an individual. That means the same signifier can have different signifieds according to the each person. For Mary, the signifier "floral perfume" presents as its signified the "feminine and romantic" feeling. To a different person -  myself, for instance -, a floral perfume does not have the same meaning. I do not see it as romantic or feminine. Instead, because the sweet smell gives me a headache, that has become my signified for it.

The roots of the equation are x = (3 + iÂ√7)/2 and x = (3 - iÂ√7)/2.

The equation x^2 - 3x + 4 = 0 can be factored as (x - 4)(x - 1) = 0.

Therefore, the roots of the equation are x = 4 and x = 1.

To calculate this, we can use the Quadratic Formula:

x = [-b ± Â√(b^2 - 4ac)]/2a

In this equation, a = 1, b = -3, and c = 4

x = [-(-3) ± Â√((-3)^2 - 4(1)(4))]/2(1)

x = [(3) ± Â√(9 - 16)]/2

Reflection is the act of flipping a figure over a line. The act of rotating involves turning a figure a predetermined distance around a point. And hence, reflection and rotation is not the same.

In mathematics, a reflection is an isometric mapping from a Euclidean space to itself with a set of fixed points called the hyperplane, also referred to as the axis or plane of reflection.

The image created by a reflection is the figure's mirror image in the axis or plane of reflection.

Rotation:

The concept of rotation in mathematics has its roots in geometry.

Any rotation is a movement of a certain area while maintaining at least one point. It may be used to describe, for instance, how a rigid body moves around a fixed point.

So, we can say that flipping a figure over a line is called reflection. Rotation is the process of turning a figure a specific amount around a point.

Therefore, reflection is the act of flipping a figure over a line. The act of rotating involves turning a figure a predetermined distance around a point. And hence, reflection and rotation are not the same.

When the original graph is mirrored around the line y = x, the inverse function's graph may be determined, the domain of the inverse, f-1(x), corresponds to the range of the original function (x), the x intercept of f-1(x) is the y intercept of f, and the range of the inverse f-1(x) is the domain of f(x) (x).

The intercept theorem, also referred to as Thales' theorem, the basic proportionality theorem, or the side splitter theorem, is a crucial concept in basic geometry that discusses the ratios of different line segments that are produced when two intersecting lines are intercepted by a pair of parallels.

It is equivalent to the ratios in similar triangles theorem. It is typically credited to the Greek mathematician Thales. Despite the fact that its first known demonstration may be found in Euclid's Elements, it was known to the ancient Babylonians and Egyptians.

Similarity and the intercept theorem go hand in hand. It is equivalent to the idea of similar triangles in that it may be used to demonstrate both the qualities of similar triangles and the intercept theorem.

Hence, When the original graph is mirrored around the line y = x, the inverse function's graph may be determined, the domain of the inverse, f-1(x), corresponds to the range of the original function (x), the x intercept of f-1(x) is the y intercept of f, and the range of the inverse f-1(x) is the domain of f(x) (x).

3x - 5y=-9 has a [tex]\frac{-3}{5}[/tex] slope.

A line's steepness can be determined by looking at its slope. To find the slope of a line, you need to have the equation of the line in the form y = mx + b, where m is the slope and b is the y-intercept (the point at which the line crosses the y-axis).

To put the equation 3x - 5y = -9 in this form, you can start by isolating the y term on one side of the equation:

3x - 5y = -9

-5y = -3x - 9

y = (-3/5)x - (9/5)

The slope of the line is therefore -3/5.
