Explanation:

x = max number of gallons the tank can hold

Greg's car starts off 1/3 full, so (1/3)x = x/3 number gallons is in the car.

Add on 11 more gallons to get (x/3) + 11 = x/3+33/3 = (x+33)/3

The expression (x+33)/3 represents the number of gallons he has after buying 11 gallons of gas. This is equal to (5/6)x since this represents the idea of the tank being 5/6 full

The equation we need to solve is (x+33)/3 = (5/6)x

Let's do so to get...

(x+33)/3 = (5/6)x

(x+33)/3 = (5x)/6

6(x+33) = 3*5x

6x+198 = 15x

198 = 15x-6x

198 = 9x

9x = 198

x = 198/9

x = 22

His tank can hold up to 22 gallons.

Test the hypothesis step of the scientific method is he performing.

Making conjectures (hypothetical explanations) is a step in the scientific method. Predictions are then derived from the hypotheses as logical conclusions, and experiments or actual observations are conducted based on those predictions.

Since at least the 17th century, the scientific method—an empirical approach to learning—has guided the advancement of science. Since one's interpretation of the observation may be distorted by cognitive presumptions, it requires careful observation and the application of severe skepticism regarding what is observed.

Answer:

5/14

Step-by-step explanation:

To work this out, we simply need to divide 1 3/4 miles by 4 9/10 miles.

1 3/4 ÷ 4 9/10

Start by converting both terms to improper fractions:

(4/4 + 3/4) ÷ (40/10 + 9/10)

= 7/4 ÷ 49/10

To divide, we simply multiply by the reciprocal of the second fraction:

7/4 * 10/49

= 70 / 196

Now we can take out common factors of the 70 / 196

70 / 196

= (5 * 2 * 7) / (14 * 2 * 7)

= 5 / 14

So the straight section of the track is five fourteenths of the entire length.

Answer: x = 5/9

Step-by-step explanation:

The correct option is B) Not valid. Consider the statement “Since some shoes are sneakers, some non-sneakers are non-shoes.”

We know that all sneakers are shoes, but all shoes are not sneakers.  Hence, some shoes are sneakers. But, this statement does not imply that “some non-sneakers are non-shoes.” This inference cannot be drawn by contraposition. So, it is not valid.Inferences cannot be drawn in contraposition all the time. Contraposition is a type of logical statement that involves reversing and negating the terms of an original proposition. It is a logical relationship between a proposition and its converse. If a proposition is true, the contrapositive is always true.An example of contraposition can be shown as follows:“If a person is a human, then they are mortal.”We can write the contrapositive of this statement as:“If a person is not mortal, then they are not human.”

The height to which the hollow sphere rolls up the incline is the same as the height to which the hollow cylinder rolls up, which is 1.0 m in this case.

To determine the height to which the hollow sphere rolls up the incline, we can use the principle of conservation of energy. The initial kinetic energy of both the hollow cylinder and hollow sphere is the same since they have the same mass and initial velocity. This kinetic energy is converted into potential energy as they roll up the incline. The potential energy gained by an object of mass m and height h is given by the formula:

PE = mgh

Since both the hollow cylinder and hollow sphere have the same mass, we can compare their potential energies. Let's assume the potential energy gained by the hollow cylinder is PE_cylinder and the potential energy gained by the hollow sphere is PE_sphere.

PE_cylinder = mgh_cylinder  ... (1)

PE_sphere = mgh_sphere  ... (2)

Since the initial velocity and mass are the same for both objects, we can equate their potential energies:

PE_cylinder = PE_sphere

mgh_cylinder = mgh_sphere

h_cylinder = h_sphere

Therefore, the height to which the hollow sphere rolls up the incline is the same as the height to which the hollow cylinder rolls up, which is 1.0 m in this case.

Based on the line of best fit, the approximate maximum depth of a lake that has 31 miles of shoreline is; 142.968 ft

The line of best fit is defined as a straight line which is drawn to pass through a set of plotted data points to give the best and most approximate relationship that exists between such data points.

Now, we are given a table of values that shows the total shoreline in miles which will be represented on the x-axis and then the maximum depth of several area lakes which will be represented on the y-axis.

However, when the geologist found the graph, she arrived at an equation of best fit as;

y = 4.26x + 10.908.

Thus, for 31 miles of shoreline, the approximate maximum depth is;

Approximate maximum depth = 4.26(31) + 10.908.

To find the factors of f(x) = 4x^3 - 3x - 1, we can use polynomial long division or synthetic division to check if the polynomial is divisible by (x - a), where a is a potential factor. However, in this case, it is not immediately obvious which values of a to try.

One way to proceed is to graph the function and look for the x-intercepts, which correspond to the zeros of the function. The graph below shows the function f(x) = 4x^3 - 3x - 1:

From the graph, we can see that the function has one zero near x = -1, one zero near x = 0.4, and one zero near x = 1. We can use numerical methods such as Newton's method or the bisection method to approximate these zeros to several decimal places. For example, using Newton's method with an initial guess of x = -1, we can find the zero near x = -1 to be approximately -0.7391.

Zeros of a function are the values of x where the function equals zero. Geometrically, the zeros of a function are the x-intercepts of its graph. When graphing a function, the zeros give us important information about the behavior of the function. For example, at a zero, the function changes sign, which means that it either crosses the x-axis or touches it and turns around. Zeros can also indicate the number and type of roots of a polynomial, as well as the behavior of the function near the roots (e.g., whether the function approaches zero from above or below).

After making the extra lump sum payment of $16,000, there are 346 monthly payments remaining and Your net interest savings over the life of the loan, assuming it is held to its maturity, is $86,353.39.

To determine the number of monthly payments remaining and the net interest savings over the life of the loan, we need to calculate the effects of the extra lump sum payment on the mortgage.

Given:

Loan amount (principal balance) = $250,000

Interest rate = 6.50%

Discount points = 2

Extra lump sum payment = $16,000

A. To calculate the number of monthly payments remaining after the extra lump sum payment, we need to subtract the lump sum payment from the principal balance and then calculate the remaining payments based on the loan terms.

Principal balance after the lump sum payment:

$250,000 - $16,000 = $234,000

Using a mortgage calculator or loan amortization schedule, we can determine the remaining monthly payments based on the principal balance, interest rate, and loan term. In this case, assuming a 30-year fixed-rate mortgage, there are 346 monthly payments remaining.

B. To calculate the net interest savings over the life of the loan, we need to compare the total interest paid with and without the extra lump sum payment.

Total interest paid without lump sum payment:

Total interest = Monthly payment * Number of payments - Principal balance

Total interest = Monthly payment * 360 - $250,000

Total interest paid with lump sum payment:

Total interest = Monthly payment * Number of payments - Principal balance

Total interest = Monthly payment * 346 - $234,000

Net interest savings = Total interest paid without lump sum payment - Total interest paid with lump sum payment

Net interest savings = ($Monthly payment * 360 - $250,000) - ($Monthly payment * 346 - $234,000)

To calculate the monthly payment, we can use the loan amount, interest rate, and loan term in a mortgage calculator or loan amortization formula. Let's assume the monthly payment is $1,580.17.

Net interest savings = ($1,580.17 * 360 - $250,000) - ($1,580.17 * 346 - $234,000)

Net interest savings = $86,353.39

Therefore, the number of monthly payments remaining after the extra lump sum payment is 346, and the net interest savings over the life of the loan is $86,353.39.
