The formula for calculating the volume of a cone is expressed as:

where:

r is the radius

h is the height

Given the following

r = 12 inches

V = 3014.4 cubic inches

Substitute to determine the height

Hence the height of the cone will be 20inches

The value of 1936 divided by 8 in long division is 242.

Long Division is a method for dividing large numbers that divides the task into numerous phases that follow a sequence. Just like in conventional division problems, the dividend is divided by the divisor, yielding the quotient and, in some cases, a remainder.

The steps are:

Step 1: Take the first digit of the dividend from the left.

Step 2: Then divide it by the divisor and write the answer on top as the quotient.

Step 3: Subtract the result from the digit and write the difference below.

Step 4: Bring down the next digit of the dividend

Using the above step the division is 242.

The probability of a student living off campus is 0.35.

It should be noted that probability simply means the likelihood that something will occur.

Remember the multiplication rule for conditional probability: P(B AND A)=P(B/A)P(A)

Rearranging, we find that P(A)=P(B AND A)P(B/A)

So if we think of A= the event a student lives off campus and B = event a student eats at the cafeteria, then we can plug in the known information to find:

P(A)=0.07 / 0.20

= 0.35

Answer:

To use the given table to find product of the two polynomials.

Given that,

Explanation:

Using the table, we get it as,

we get,

we get,

Answer is:

a. Since GC bisects FGH and the angle FGH = 122°, we know that the angle FGC = 122/2 = 61°

b. Since GC bisects FGH and the angle CGH = 42°, we know that the angle FGH = 2*42 = 84°

We will solve as follows:

First: We will use the i, j, k vector notation to describe each point as a vector:

Now, we have that the time it takes to get from A to B is 3 hours (t1). And the time it takes from B to C is 1 hour (t2).

Second: We determine the speed from A to B:

Third: We now determine the value of C:

So, we would have that the coordinates of C are:

The place value of 6 in 205.876 is 6 thousandth

The trigonometric functions tangent, sine and cosine are related by the following equation:

In this case, the angle is y°, so:

Since we want the cosine, we can solve for it ans substitute the given tangent and sine:

This corresponds to the third alternative.

The inequlaity is ;

And the solution is;

Let the number be x

The number divided by 3

That is x/3

less two means minus 2

x/3 - 2

Is at most 2 means it is less than or equal to 2

so the inequality is;

The first step of substitution method for given system is put x = 3y +3 in place of x into the equation 2x+3y=-12 .

The system of the equations in two variables x and y consists of two equation of the form a₁ x + b₁ y = c₁

and a₂ x + b₂ y = c₂

where a₁, a₂, b₁, b₂ , c₁, c₂ are constants

For substitution method, first expression of one variable is found from one equation and then put this expression in another equation to create a linear equation in second variable. Solve the linear equation in one variable for second variable and then put the value of second variable in first equation to solve for first variable

Given system of equations is :

2x + 3y = -12       .....(1)

x = 3y + 3          .....(2)

So the first step will be take expression for one variable from one equation and put it into another equation.

Take x = 3y +3 which is an expression for x from equation (2),

Then put it into equation (1)

⇒ 2 (3y +3 ) + 3 y = -12 , This is the first step of substitution method for this variable

two thousand people attend the theater during the week of a movie's release (option A)

The equation:

y = -50x + 2000

y = number of people in the theater

x = number of weeks since the movie release

2000 will be the number of people in the theater at the begining of the movie release

y-intercept of an equation represent the value of y when x is zero

The 2000 is the number of people in the theater at week zero.

Hence, y-intercept indicate two thousand people attend the theater during the week of a movie's release (option A)

The amount of the remaining balance of the car loan is $26293.1103.

Given,

The initial loan amount, P = 27000

The rate of interest, r = 6.2%

Time period, t = 5 years

Interest is compounded monthly.

The 20th payment of the loan = $524.50

We have to find the  remaining balance of the car loan.

Here,

Amount, A = P[1 + r/n]^nt

Where,

A is the total amount = principal amount + compound interest

P is the principal amount

r is the rate of interest

n is the number of times compounded

t is the time period

So,

A = P[1 + r/n]^nt

A = 27000 × [1 + 6.2/100/12]^12 × 5

A = 27000 × [12.062/12]^60

A = 27000 × [1.005166]^60

A = 27000 × 1.362

A = 36783.1103

The total amount should be paid after 60 months is $36783.1103

Now,

The 20th payment = $524.50

That is,

524.20 × 20 = 10490

$10490 is paid and the balance amount;

36783.1103 - 10490 = 26293.1103

Therefore,

The amount of the remaining balance of the car loan is $26293.1103.

Each theater sold tickets at ($7.50 a piece, if each theater received the same number of moviegoers, each theater make $6192.85 using arithmetic operations.

The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or more quantities. They cover topics like the study of numbers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry. Without applying the laws of arithmetic operations, we are unable to solve the issue. The four fundamental rules of mathematics are addition, subtraction, multiplication, and division.

Let the amount of each theater get be x,

No. of theaters are = 7

Cost of each ticket = $7.50

No. of people = 5780

Then we can say,

7x = 5780 ×7.50

x = [tex]\frac{5780\times7.50}{7}[/tex]

Given -

f(x) = x⁵ - 4x³ + 7x² + 3x - 5

To Find -

How many positive real zeroes does f(x) have =?

Step-by-Step Explanation -

We have

f(x) = x⁵ - 4x³ + 7x² + 3x - 5

where the signs of coefficients are:

+ - + + -

We can see there are three changes in the sign in f(x).

So, from

Descarte's rule,

there are either 3 0r 1 positive real roots

Now,

f(-x) = -x⁵ + 4x³ + 7x² - 3x - 5

Signs: - + + - -

So, here f(-x) has two sign changes.

From this we can conclude there is at least 1 real root and either 4, 2 or 0 imaginary roots.

Final Answer -

Positive real zeroes f(x) have =

Minimum = 1

Maximum = 3

We are to create a data set of 4

that is a, b, c, d

mode means a number that occur the most

Median means the middle number

Mean means the average number

in the set, we must have a mode of 3

3, 3,

to get a median of 6, we need a number when we add to three and divide by 2 will give us 6

the number is 9

3 + 9 / 2

12/ 2 =

3, 3 , 9, d

the last number is d and it is unknown

since means is 10

mean = summation of all the numbers in the data set / the total number

the total number is 4

mean = 10

10 = 3 + 3 + 9 + d / 4

cross multiplication

10 x 4 = 3 + 3 + 9 + d

40 = 6 + 9 + d

40 = 15 + d

isolate d

d = 40 - 15

d = 25

therefore, the data set with a mode of 3, median of 6 and a mean of 10 are

3 , 3 , 9, 25

Answer:
