Therefore , the solution of the given problem of percentage comes out to be $18 is the original price.

In mathematics, a percentage is any value that can be represented as a fraction of 100. There are also sporadic uses of the abbreviations "pct.," "pct," or "pc." Nonetheless, it is typically denoted by the "%" symbol. The proportional amount is flat and lacks any dimensions. As percentages have a numerator of 100, they can be thought of as fractions. The percent symbol (%) must come after a number to denote that it is a percentage.

Here,

To determine the sale price of the jeans including tax, Jo should follow these steps:

Find the sale price of the jeans before tax:

Sale price = Original price - Discount

= $30 - 40%($30)

= $30 - $12

= $18

Find the tax amount by multiplying the sale price by the tax rate (which varies depending on the location):

Tax amount = Sale price x Tax rate

Add the sale price and the tax amount to get the total cost:

Total cost = Sale price + Tax amount

So the best plan for Jo to determine the sale price including tax would be to follow the above steps using the applicable tax rate in their location.

Answer:

Step-by-step explanation:

We can consider the grassy plot as a circle with radius = 42/2 = 21 m

The grassy plot and the path together form another circle with radius = 21 + 3.5 = 24.5 m

Area of a circle = πr² where r is the radius

Area of grassy plot = π x 21² = 441π m²

Area of outer circle (grassy plot + path) = π x (24.5)² = 600.25π m²

Area of the outer path alone = 600.25π - 441π = 159.25π = 500.30 sq meters

Cost of paving 1 square meter = ₹ 4

Cost of paving  500.3 sq m = 500.3 x 4 = ₹ 2,001.20

So the linear model that describes the growth of the organism over the 5 hour period is: y = 6x + 16, where x is the number of hours and y is the weight of the organism in mg.

A linear model is a mathematical equation that describes a linear relationship between two or more variables. In other words, it is a model that assumes that the relationship between the variables can be represented by a straight line. Linear models are commonly used in various fields, including economics, finance, engineering, and science, to analyze and predict the relationship between variables. They are particularly useful when analyzing data that shows a linear trend, or when making predictions based on historical data. Linear models can be simple or multiple, depending on the number of independent variables involved. They can also be adjusted to fit nonlinear data by transforming the variables or using a different model altogether.

Here,

To find a linear model that describes the growth of the organism over time, we need to determine the rate of growth (change in weight per unit time) and the initial weight.

The rate of growth can be found by taking the difference between the final weight and the initial weight and dividing by the time period:

Rate of growth = (final weight - initial weight) / time period

= (46 mg - 16 mg) / 5 hours

= 6 mg/hour

So the organism is growing at a rate of 6 mg per hour.

The initial weight of the organism is given as 16 mg.

Now we can write the equation of the line as:

y = mx + b

where y is the weight of the organism in mg, x is the time in hours, m is the rate of growth in mg/hour, and b is the initial weight in mg.

Substituting the values we found, we get:

y = 6x + 16

In formally proving that lim (x² + x) = 42

m = ⌈√ε⌉ - 1

It is shown that for any ε > 0, there exists a δ > 0 such that if 0 < |x - c| < δ, then |(x^2 + x) - 42| < ε.

|(x^2 + x) - 42| = |x^2 + x - 42| = |(x - 6)(x + 7)|

Since |x - c| < δ, we have:

|x - 6| < δ + 6 < δ(m+2)

|x + 7| < δ + 7 < δ(m+2)

Since δ = ε/(m+1), we can solve for m:

m+1 = ε/δ

m+1 = ε/ (ε/(m+1) )

(m+1)^2 = ε

m^2 + 2m + 1 = ε

m^2 + 2m + (1-ε) = 0

Using the quadratic formula, we get:

m = (-2 ±  ⌈√ε⌉ - 1 (4 - 4(1-ε)))/2 = -1 ± √(ε)

10.468 rounded to the nearest hundredth would be 10.47

4 = tenths place

6 = hundredths place

8 = thousandths place

8 >= 0.5 so 10.468 --> 10.47

Answer: 10.47

Step-by-step explanation: After the decimal, it goes tenths, hundredths, thousandths. So we're looking at the second place after the decimal, which is a 6, and the next number is 8. Think of it like 68, rounding up to the next ten, or 70. So that turns it into 10.470, and you get to drop the zero to make it 10.47.

The frequency of the function f(x) is 1/π.

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable. In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

We need to find the frequency of given function;

f(x)=1/4 cos(2x)+5

To finding the period and then use the general relation frequency

frequency = 1/period

In the given function f(x)=1/4 cos(2x)+5 here, only the constant 2 which will multiply with x effects the period.

As we know that 2π is the period of cosx then the period of cos(2x) is

2x=2π

x=π

So, the period of cos(2x) is π

43% * 258 = 110.94 (£110.94 is 43% of £258) 258 + 110.94 = 368.94

Step-by-step explanation:

The equation that shows  the damping ratio for a mass-spring-damper system which is defined in terms of the mass, m, stiffness, k, and damping, b is  ζ = b / (2sqrt(mk)).

The damping ratio ζ is defined as the ratio of the damping coefficient b to the critical damping coefficient b_c, which is the minimum damping required to prevent the system from oscillating.

The damping ratio is a dimensionless quantity that represents the amount of damping in the system relative to the critical damping needed to prevent oscillations. A higher damping ratio indicates a more heavily damped system, while a lower damping ratio indicates a less damped system that may oscillate more.

The motion of a mass-spring-damper system can be described by a second-order linear ordinary differential equation (ODE) of the form:

md²x/dt² + bdx/dt + kx = F(t)

where m is the mass of the system, b is the damping coefficient, k is the spring constant, x is the displacement of the mass from its equilibrium position, and  the external force applied to the system is F(t).

The critical equation will be -

b_c = 2√(mk)

Therefore, the damping ratio can be expressed as:

ζ = b / b_c

Substituting the expression for b_c into the above equation, we get:

ζ = b / (2√(mk))

The first three terms of the AP are -4.28, -7.28, -10.28

An arithmetic sequence in algebra is a sequence of numbers where the difference between every two consecutive terms is the same.

Given that, the sum of the first 9 terms of an AP is 56 and the sum of the next 10 terms is 430. we need to find the first three terms of the AP.​

The sum of the first n terms in an arithmetic sequence is (n/2)⋅(a₁+aₙ). It is called the arithmetic series formula.

Therefore,

56 = 9/2(2a₁+(9-1)d)

12.44 = 2a₁+7d

2a₁ = 12.44-7d....(i)

430 = 19/2(2a₁+18d)

45.26 = 2a₁+18d

2a₁ = 45.26-18d....(ii)

Equating the RHS of the equations,

12.44-7d = 45.26-18d

11d = 32.82

d = 3

Put d = 3, in equation (i)

2a₁ = 12.44-7(3)

2a₁ = -8.56

a₁ = -4.28

Therefore, the next three terms = -4.28, -7.28, -10.28

Answer:

The movie theater sold 85 large bags of popcorn and 204 small bags of popcorn.

Step-by-step explanation:

Let's use the following variables to represent the number of large and small bags of popcorn sold:

L: the number of large bags of popcorn sold

S: the number of small bags of popcorn sold

We can then write a system of equations based on the information given in the problem:

L + S = 289 (the total number of bags sold is 289)

4L + S = 544 (the total revenue from popcorn sales is $544)

To solve for L and S, we can use the method of substitution. Rearrange the first equation to solve for one variable in terms of the other:

L = 289 - S

Substitute this expression for L in the second equation and solve for S:

4(289 - S) + S = 544

1156 - 4S + S = 544

3S = 612

S = 204

Now that we know that 204 small bags of popcorn were sold, we can use the first equation to solve for L:

L + S = 289

L + 204 = 289

L = 85

Therefore, the movie theater sold 85 large bags of popcorn and 204 small bags of popcorn.
