The equation shows how to find the length of each piece is L = R / N and the length of each piece is 1.5 feet.

To find the length of each piece, we can use the following equation:

Length of each piece = Total length of the ribbon / Number of pieces

In mathematical terms, we can represent this equation as:

L = R / N

Where,

L is the length of each piece

R is the total length of the ribbon (66 feet in this case)

N is the number of pieces (44 in this case)

In this problem, we are given a 66-foot ribbon and we are asked to cut it into 44 equal pieces. We need to find out the length of each piece.

Using this equation, we can easily find the length of each piece:

L = 66 / 44

L = 1.5 feet

Therefore, each piece of the ribbon is 1.5 feet long.

To find a polynomial function of degree 3 such that f(10) = 17 and the zeros of f are 0, 5, and 8, we can use the factored form of the polynomial. The polynomial can be written as f(x) = (17/20)x(x - 5)(x - 8).

If the zeros of a polynomial function are 0, 5, and 8, then the factored form of the polynomial can be written as: f(x) = k(x - 0)(x - 5)(x - 8)

To find a polynomial function of degree 3 such that f(10) = 17 and the zeros of f are 0, 5, and 8, we can use the factored form of a polynomial. The factored form of a polynomial is the product of its factors, which are its linear binomials that correspond to its zeros.

For example, if a polynomial has zeros of 1, 2, and 3, then its factored form can be written as (x - 1)(x - 2)(x - 3). We can use this concept to find the factored form of the polynomial with zeros of 0, 5, and 8, which is:

f(x) = k(x - 0)(x - 5)(x - 8)

where k is a constant coefficient that we need to determine. We can use the given condition that f(10) = 17 to solve for k. When we plug in x = 10, we get:

f(10) = k(10 - 0)(10 - 5)(10 - 8) = 2k * 5 * 2 = 20k

Since f(10) = 17, we can set 20k = 17 and solve for k:

k = 17/20

Therefore, the polynomial function of degree 3 with the given conditions is:f(x) = (17/20)x(x - 5)(x - 8)

the augmented matrix is [A:B] = [tex]\left[\begin{array}{ccc}1&1&1:6\\1&2&3:14\\1&4&7:30\end{array}\right][/tex]

we need to reduce the augmented matrix [A:B] to row echelon form by applying elementary row transformations only.

[A:B] = [tex]\left[\begin{array}{ccc}1&1&1:6\\0&1&2:8\\0&3&6:24\end{array}\right][/tex]

which is the row echelon, form of the matrix [A:B]

we have rank of [A:B] = the number of the non zero rows in echelon form = 2

also by the same elementary transformation we get,

The length of BD in the triangle is 24 units.

The triangles are similar by angle bisector theorem. The angle bisector theorem states that the angle bisector of an angle of a triangle divides the opposite side into two parts that are proportional to the other two sides of the triangle.

Therefore, let's find BD.

Hence, using the proportion,

12  / 20 = x / x + 6

cross multiply

12(x + 6) = 20x

12x + 72 = 20x

72 = 20x - 12x

72 = 8x

divide both sides by 8

x = 72  /8

x = 9

Therefore,

BD = x + x + 6 = 2x + 6

BD = 2(9) + 6

BD = 18 + 6

Newington's budget in the "previous year" is $119.2 million

The term "budget" refers to a financial plan for a given period that outlines expected expenses and revenues. The previous year's budget for Newington is the financial plan that the town had for the previous fiscal year.

Assuming the previous year's budget refers to the fiscal year that ended just before the current fiscal year, we can find the amount by looking at the town's financial statements for that period. These statements will show the town's revenues and expenses for that fiscal year, and the difference between the two will be the budget.

If the town had $100 million in revenues and $95 million in expenses in the previous fiscal year, then the budget for that year would be $5 million. This means that the proposed $124.2 million budget for the upcoming year is a 4.7% increase from the $119.2 million budget of the previous year.

Leo Gandolfi would save $54.34 by paying off the loan when the next payment is due.

What is percentage ?

Percentage can be defined as product of ratio of given value, total value and hundred.

To find out how much Leo Gandolfi saves by paying off the loan early, we need to first calculate how much interest he would pay if he were to continue making payments for the full 6-month term of the loan.

The total interest on the loan for the full 6 months can be calculated as:

Total interest = Total payments - Loan amount

We know the loan amount is $1,800, and the monthly payment is $310.50, so the total payments for the full 6 months would be:

Total payments = Monthly payment x Number of payments

Total payments = $310.50 x 6 = $1,863

Therefore, the total interest paid over the 6-month term of the loan would be:

Total interest = $1,863 - $1,800 = $63

Now, we need to calculate how much interest Leo Gandolfi would pay if he were to pay off the loan after making 4 payments.

The remaining balance on the loan after 4 payments is $612.34, so if Leo were to make one more payment, the remaining balance would be:

Remaining balance = $612.34 - $310.50 = $301.84

To calculate the interest paid on this remaining balance, we need to calculate the interest for one month:

Monthly interest rate = Annual interest rate / 12

Monthly interest rate = 12% / 12 = 1%

Monthly interest = Monthly interest rate x Remaining balance

Monthly interest = 1% x $301.84 = $3.02

Therefore, if Leo were to make one more payment, he would pay $310.50, which includes both the principal and the interest. So, the amount of interest he would pay if he were to pay off the loan after 4 payments is:

Interest paid = Total payment - Remaining balance

Interest paid = $310.50 - $301.84 = $8.66

So, by paying off the loan early, Leo Gandolfi would save:

Savings = Total interest - Interest paid

Savings = $63 - $8.66 = $54.34

Therefore, Leo Gandolfi would save $54.34 by paying off the loan when the next payment is due.

Answer: If the army regiment had 400 soldiers with provisions for 80 days, the food would last each soldier for 80 days / 400 soldiers = 0.2 days per soldier.

If 80 soldiers moved out, the number of soldiers remaining in the regiment would be 400 soldiers - 80 soldiers = 320 soldiers.

Since the amount of provisions has not changed, the food would last for 80 days / 320 soldiers = 0.25 days per soldier.

Therefore, the food would last the 320 soldiers for 0.25 days * 320 soldiers = 80 days.

4 4/5 miles

Step-by-step explanation:

2 4/5 = 2 + 4/5 = 10/5 + 4/5 = (10+4)/5 = 14/5

Proportions:

14/5 miles ⇒ 7/12 hour

A miles ⇒ 1 hour

A = (14/5 miles)(1hour) / (7/12 hour)

A = (14/5)/(7/12)

A = (14*12) / (5*7)

A = 168 / 35

A =  140/35 + 28/35

A = 4 + 28/35

A = 4 + 4/5

A = 4 4/5 Miles

Step-by-step explanation: Because of the square in the corner

The statement "the probability of the union of two events occurring can never be more than the probability of the intersection of two events occurring." is false.

What is meant by probability?

The probability of an occurrence is a figure that represents how likely it is that the event will take place. In terms of percentage notation, it is expressed as a number between 0 and 1, or between 0% and 100%. The higher the likelihood, the more likely it is that the event will take place.

The given statement is:

"the probability of the union of two events occurring can never be more than the probability of the intersection of two events occurring."

This is a false statement.

The probability of the union of two events is the probability of individual events without considering the probability of the intersection of the events.

When the events do not have an intersection, then the probability of a union of events is greater than the probability of an intersection of events.

The chance of both occurrences occurring together is given by the union of two events, but the probability of both events occurring simultaneously is given by the intersection of two events, which is smaller than probability of union of events.

Therefore the statement "the probability of the union of two events occurring can never be more than the probability of the intersection of two events occurring." is false.
