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:

In 1 hour run:

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

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.

There is no real solution to the given equation s = 4 + sqrt(s+2) with value of s = 2, s = 7, s = 2 or s = 7.

To solve the equation:

s = 4 + sqrt(s+2)

We can start by isolating the square root term on one side:

s - 4 = sqrt(s+2)

Then, we can square both sides to eliminate the square root:

(s - 4)^2 = s + 2

Expanding the left side:

s^2 - 8s + 16 = s + 2

Bringing all terms to one side:

s^2 - 9s + 14 = 0

We can solve for s using the quadratic formula:

s = (9 ± sqrt(9^2 - 4(1)(14))) / 2(1)

s = (9 ± sqrt(49)) / 2

s = (9 ± 7) / 2

So the two possible solutions are:

s = 8/2 = 4

s = 2/2 = 1

However, we need to check if these solutions satisfy the original equation.

If we plug s=4 into the equation, we get:

4 = 4 + sqrt(4+2)

4 = 4 + sqrt(6)

This is not true, since the right-hand side is greater than the left-hand side.

If we plug s=1 into the equation, we get:

1 = 4 + sqrt(1+2)

1 = 4 + sqrt(3)

This is also not true.

Therefore, there is no real solution to the equation s = 4 + sqrt(s+2).

The measures of angle possible for of an isosceles triangle when one angle given is 140° then other two angles is 20°.

In an isosceles triangle, two of the angles have the same measure. Let's call this measure x. Since the sum of the angles of a triangle is 180 degrees, we can set up an equation:

x + x + 140° = 180°

Simplifying the equation, we get:

2x + 140° = 180°

Subtracting 140° from both sides, we get:

2x = 40°

Dividing both sides by 2, we get:

x = 20°

So the other two angles in the isosceles triangle each measure:

x = 20°

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:
