The circumference of the circle is 25.12 inches

From the question, we have the following parameters that can be used in our computation:

Radius = 4 inches

The circumference of a circle can be calculated using

C = 2πr

Substitute the known values in the above equation, so, we have the following representation

C = 2 * 3.14 * 4

Evaluate

C = 25.12

There are 30 questions for 2 points and 10 questions for 4 point.

What is elimination method?

The elimination approach involves taking one variable out of the system of linear equations by utilizing addition or subtraction together with multiplication or division of the variable coefficients.

Given that, the total number of equations is 40. Total point on the paper is 100 points.

There are two types questions, one type question contains 2 points and other type question contains 4 points.

Assume that, there are x questions for 2 points and y questions for 4 points.

The total number of questions is x + y.

The total point is 2x + 4y.

Therefore,

x + y = 40  ......(i)

2x + 4y = 100  .....(ii)

Multiply 2 with equation (i)

2x + 2y = 80

2x + 4y = 100

___________

       -2y = -20

Divide both sides by -2:

y = 10

Putting y = 10 in equation (i)

x + 10 = 40

x = 30

Answer:

all values less than -13

Step-by-step explanation:

3x + 5 < 2x - 8

3x + 5 - 5 = 2x - 8 - 5  ==> isolate x by subtracting 5 on both sides

3x < 2x - 13  ==> simplify

3x - 2x < 2x - 2x - 13  ==> subtract 2x from both sides to move x to the left

                                         side of the inequality

x < -13  ==> simplify

Hence, the answer is all values less than -13.

The solution is 60 grams

The size of each of the balls is given by the equation x = 60 grams

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the size of the balls be represented as = x

The number of balls = 2

So , the total size of the balls = 2x

Now , the equation will be

The weight of all the elements = 160 grams   equation (1)

The weight is balanced by = 40 grams + 2x   equation (2)

Now , equation (1) = equation (2)

Substituting the values in the equation , we get

160 = 2x + 40

On simplifying the equation , we get

Subtracting 40 on both sides of the equation , we get

2x = 120

Divide by 2 on both sides of the equation , we get

x = 60 grams

Therefore , the value of x is 60 grams

Hence , the size of the ball is 60 grams

The resulting sampling technique is Stratified sampling.

As in the concept of statistical study, sampling methods refer to how we select members from the population to be in the study and if a sample isn't randomly selected, it will probably be biased in some way and the data may not be representative of the population.

Here we need to find the type of sampling method.

Here the Stratified random sampling involves classifying the units of the population into different strata.

And the give units in each stratum should possess similar characteristics which then allows the researcher to pick a sample from each.

Then the stratified sampling approach can be divided into proportionate stratified sampling and disproportionate stratified sampling

Therefore, these method is employed in cases where the population is heterogeneous.

The centroid of the region in the first quadrant bounded by the given curves is (81/170, 81/170).

In the given question, we have to find the centroid of the region in the first quadrant bounded by the given curves.

The given curves are:

y = x^8, x = y^8

We can write the curves as

y = x^8...........................(1)

y = x^{1/8}.......................(2)

Now putting the value of y from equation 1 in equation 2, we get

x^8 = x^{1/8}

Now simplifying,

x^{64} = x

x^{64}-x = 0

x(x^{63} - 1) = 0

After equating equal to zero,

x = 0, x = 1

The rate at which the radius is increasing is; 0.006 in/min

We are given that the formula for the volume of  a spherical balloon is;

V = ⁴/₃πr³

where r is the radius

The volume is increasing at the constant rate of 0.78 inches per minute. Thus;

dV/dt = 0.78

Now, differentiating with respect to t gives;

dV/dt = ⁴/₃(3πr²)(dr/dt)

At radius of 3.2 inches, we have;

0.78 = 4π * 3.2² * dr/dt

dr/dt = 0.78/(4π * 3.2²)

dr/dt = 0.006 in/min

Given equation:

Solve it in below steps:

The function is: c(x) = 5.50 + 21.60x. This means that for each ticket purchased, an additional $21.60 will be added to the service fee of $5.50.

The total cost for ordering 5 tickets is $108.00. This means that each ticket costs $20.50 plus a service fee of $5.50.

Therefore, we can create a linear function that represents the total cost when x tickets are ordered. The function is: c(x) = 5.50 + 21.60x. This means that for each ticket purchased, an additional $21.60 will be added to the service fee of $5.50.

When x = 5, then c(x) = 5.50 + 21.60x = 5.50 + 21.60(5) = 108.00, which matches the given total cost.
