One Kung Pao chicken contains 1620 calories. One Big Mac contains 500 calories.

What is an equation?

A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.

Assume that one Kung Pao chicken content x calories and one Big Mac content y calories.

Given that one Kung Pao chicken and two Big Macs provide 2620 calories.

Two Kung Pao chickens and one Big Mac provide 3740 calories.

Now using the variable finding calories:

One Kung Pao chicken and two Big Macs provide x + 2y calories.

Two Kung Pao chickens and one Big Mac provide 2x + y calories.

The system of equations is:

x + 2y = 2620  ......(i)

2x + y = 3740  .....(ii)

Using the elimination method to solve the given equations.

Multiply equation (i) by 2 and subtract it from equation (ii)

2x + y = 3740

2x + 4y = 5240

(-)  (-)      (-)

_____________

      -3y = -1500

Divide both sides by -3:

y = 500.

Putting y = 500 in equation (i)

x + 2(500) = 2620

x + 1000 = 2620

x = 1620

According to the line of best fit, 79 consumers are predicted to use their card to pay during a day when 90 customers pay in cash. The correct answer is C.

The answer is 79. This is because the equation of the line of best fit is:

Which is a linear equation that represents the relationship between the number of customers who pay by cash (x) and the number of customers who pay by card (y).

To use this equation to predict the number of customers who pay by card on a day when 90 customers pay by cash, we can substitute x = 90 into the equation:

Amount of discount allowed = 640 Rs.

VAT meaning value added tax that is attached to an item of product while bought by the buyer and also in each stage of production, distribution level. It is almost similar to a sales tax that is paid within the item price.

given, discount allowed = 20% on the market price.

VAT = 10% on the market price.

Buyer paid as VAT = 320 Rs

Assume, market price of radio = X Rs

now amount of discount = 20/100× X = 0.2X

amount of VAT = 10/100×X = 0.1X

it is said that VAT paid by buyer = 320 Rs

now 320 = 0.1X

X = 320 / 0.1 = 3200 Rs

market price of radio = 3200 Rs

amount of discount = 20/100× 3200 = 640 Rs

[tex]\displaystyle f^{-1}(x)=\frac{1}{5}x[/tex]

Step-by-step explanation:

[tex]f(x)=5x\\\displaystyle y=5x\\x=5y\\\frac{1}{5}x=y\\ f^{-1}(x)=\frac{1}{5}x[/tex]

The inverse of the given function f(x) will be x/5.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

To find the inverse function f⁻¹(x) for f(x) = 5x, we can use the following steps:

Therefore, the inverse function of f(x) = 5x is f⁻¹(x) = x/5.

Note that f⁻¹(x) is not equal to -5x, 1/5x, or 5x.

The coordinates of point Q after dilation will be (2,-1). The correct option is B.

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that the coordinate is Q(8,-4). The point is dilated by a factor of 1/4.

The dilation of the point will be calculated as,

Q(8,-4) = Q'(8/4, -4 / 4)

The rate of increase in the circumference of the circle at the instant when the radius of the circle is 3 meters is 3 phi m/s

From the question, we have the following information :

1. Constant rate of increasing radius with respect of time (t)

  = [tex]\frac{dR}{dt}[/tex] = 0.5 m / s

2. Radius of circle is 3 meters ( 3m )

To find constant rate of increasing circumference, we have to know formula of circumference.  

We know that circumference = 2 π R

Constant rate of increasing circumference with respect of time (t) can be formulated from contant rate of increasing radius multiply with formula to find circumference

[tex]\frac{dC}{dt}[/tex] = 2πR [tex]\frac{dR}{dt}[/tex]

[tex]\frac{dC}{dt}[/tex] = 2πR ( 0.5 )

    = πR

From above equation, we know that the rate of increasing circumference is πR

When R = 3 m, we just simply subtitute πR with R=3

The constant rate will be :

Rate of increasing circumference = πR m/s

                                                        = π (3) m/s

                                                        = 3π m/s

The proportional relation is y= 2.2x

What is proportion?

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

Neena counts 11 beats in 5 seconds

So, x=11 and y=5

Using the proportionality

y = k x

k= y/x

k= 11/5

k= 2.2

Hence, the proportional relation is y= 2.2x

Answer:

2.2

Step-by-step explanation:

1. COP= constant of proportionality

What does that mean? This is how much of something you need for the variables to be proportional no matter their value. For example, if you pay 1.99 for 1 gallon of gas but then 30 dollars for 2 gallons at the same gas station, it doesn't make sense. You need to pay $3 for 2 gallons, and so on.

2. How do we find COP?

K is going to represent the constant of proportionality (COP), what we are solving for. Your equation should be k=b/a.

3. B is what comes first in the ratio, and is second. They said "beats to minutes" so beats= b and minutes= a

3. Solve: 11/5= 2.2

The number of people that will attend each game is given as follows:

The number of attendees will be of 500 on the 857th game, which does not make sense in the context of this problem, as a football team plays at most nine home games during a season. (taking the NFL in context).

The logarithmic function for this problem is defined as follows:

[tex]a(g) = 10 - \log_3{(g + 1)}[/tex]

Hence the number of people that will attend the second home game, when g = 2, is given as follows:

[tex]a(2) = 10 - \log_3{(2 + 1)}[/tex]

a(2) = 10 - 1

a(2) = 9.

Hence 9,000 people, as a(g) is measured in thousands.

The number of people that will attend the eight home game is given as follows:

[tex]a(8) = 10 - \log_3{(8 + 1)}[/tex]

a(8) = 10 - 2

a(8) = 8. (8,000, considering the unit of a(g)).

The game in which 500 people will attend is obtained as follows:

[tex]0.5 = 10 - \log_3{(g + 1)}[/tex]

[tex]\log_3{(g + 1)} = 9.5[/tex]

Applying the cube to both sides, we have that:

g + 1 = 9.5³

g = 857.
