Answer:

  17/25

Step-by-step explanation:

You want to know which of 5/16 or 17/25 is closer to 1/2.

For the sake of argument, let's assume that 17/25 is closer to 1/2. This means the difference from 1/2 is smaller than for 5/16:

  (17/25 -1/2) < (1/2 -5/16)

We can add (5/16 + 1/2) to both sides and we get ...

  17/25 + 5/16 < 1

The sum on the left is easily computed:

  (17·16 +25·5)/(25·16) < 1

  (272 +125)/400 < 1

  397/400 < 1 . . . . . . true

Our original premise is true: 17/25 is closer to 1/2.

Additional comment

A straightforward solution involves finding the positive difference of each number from 1/2, then comparing those differences. The attached calculator screen does that. It shows the difference of 17/25 from 1/2 is smaller than for 5/16, in agreement with the above.

Effectively, we're comparing the midpoint between the two numbers to 1/2. If it is below 1/2 (which it is), then the upper number doesn't have as great a distance from 1/2 as the lower number does.

This sort of comparison only works if the numbers are on either side of 1/2. If they are on the same side, the sign of their difference tells the tale.

The half-life of Potassium-40 is 1.25 billion years. The decay equation for Potassium-40 can be expressed as N(t) = N0e-kt, where N(t) is the amount of Potassium-40 at time t, N0 is the initial amount of Potassium-40, and k is the decay constant.

Decay constant is a measure of the rate at which a radioactive sample decays. It is usually expressed as the probability of a given radioactive nucleus decaying per unit time. It is related to the half-life of a radioactive sample, which is the time it takes for half of the sample to decay.

To answer part b, we need to solve N(t) = 15 mg. When rearranged, this equation becomes t = ln(15/N0)/(-k). Using the given initial amount of 36 mg and the calculated decay constant of 0.00056, we find that it will take 1.44 billion years for the specimen to decay to 15 mg.

For part c, we can use the same equation and solve for N(t). We get N(t) = N0e-kt, where N(t) is the amount of Potassium-40 at time t, N0 is the initial amount of Potassium-40, and k is the decay constant. Using the initial amount of 36 mg and the decay constant of 0.00056, we find that after 300 million years, there will be 27.72 mg of Potassium-40 left.

For part d, we can solve N(t) = N0/8. When rearranged, this equation becomes t = ln(N0/8)/(-k). With the initial amount of 36 mg and the decay constant of 0.00056, we find that it will take 2.68 billion years for Potassium-40 to decay to one-eighth of its original amount.

In response to the stated question, we can state that The new balance is equation therefore $55.59.

An equation is a mathematical assertion that establishes the equality of two expressions that are joined together by the equals sign ('='). For example, 2x – 5 = 13. 2x-5 and 13 are examples of expressions. The letter '=' connects the two expressions. A mathematical formula is called an equation if it contains two algebraic expressions on either side of the equal sign (=). It shows how the right and left formulas are equivalent to one another. Any formula will result in L.H.S. = R.H.S. (left side = right side).

We must ascertain the balance that is still owing after the payment and purchase transactions have been executed in order to calculate the unpaid balance.

The balance drops to $35.51 on April 15 ($50.51 - $15.00), a reduction of $15.00.

The account balance climbs to $54.78 ($35.51 + $19.27) on April 25.

The remaining balance is $54.78 as a result.

$44.29 * (0.18 / 365) * 30 = $0.81

The finance fee is therefore $0.81.

We combine the outstanding balance and the finance charge to determine the new balance:

The slope of the line in this situation tells us the rate of change of the balloon's altitude with respect to time.

The slope of a line represents the ratio of the change in the vertical coordinate (altitude) to the change in the horizontal coordinate (time). In this scenario, as the pilot increases the balloon's altitude to get a better view of the surroundings, the altitude changes with respect to time.

Thus, the slope of the line represents the rate of change of the balloon's altitude with respect to time. A steep slope indicates a rapid change in altitude over time, while a gentle slope indicates a slower change. By analyzing the slope, the pilot can adjust the altitude of the balloon as needed to achieve the desired view.

The cost of one glossy print is $7.84.

A quadratic equation is a polynomial equation of degree 2, where the largest exponent of the variable is 2.

An example of a quadratic equation is ax^2 + bx + c = 0, where a, b, and c are constants and x is the variable.

Let the cost of one regular print be "x" and the cost of one glossy print be "y".

From the first row, we can set up the equation:

45x + 30y = 465

From the second row, we can set up another equation:

15x + 10y = 155

We can solve for one variable in terms of the other in the second equation:

15x + 10y = 155

10y = 155 - 15x

y = (155 - 15x)/10

We can substitute this expression for y into the first equation:

45x + 30y = 465

45x + 30((155 - 15x)/10) = 465

Multiplying both sides by 10 to eliminate the fraction:

450x + 300(155 - 15x) = 4650

Simplifying:

450x + 46500 - 4500x = 4650

-4050x = -41850

x = 10.32 (rounded to the nearest hundredth)

Now we can substitute this value for x into the expression for y:

y = (155 - 15x)/10

y = (155 - 15(10.32))/10

y = 7.84 (rounded to the nearest hundredth)

When two distinct lines, l and m, are each perpendicular to the same line n, it means that the two lines have the same angle of rotation in relation to n.

An angle is a figure formed by two lines or rays diverging from a common point. It is measured in degrees, with a full circle representing 360 degrees. Angles are used to describe the direction and orientation of objects, as well as to measure the size of an area or the relationship between two lines. Angles are an important part of mathematics, used in problems such as geometry, trigonometry and calculus.

This angle is equal to 90 degrees, meaning that the two lines are parallel to one another.

Parallel lines are lines that never intersect and are always the same distance apart. This is the case for l and m because both lines are perpendicular to the same line n and, thus, have the same angle. Therefore, the two lines are parallel to one another, meaning that they will never cross and will always remain the same distance apart.

After simplifying we get, the solution to the equation as -2x + 15 = 30 is x = -7.5.

To solve the equation -2x + 15 = 30, we need to isolate the variable x on one side of the equation. We can do this by performing the same operation on both sides of the equation to maintain its balance.

First, we will subtract 15 from both sides of the equation to get:

-2x + 15 - 15 = 30 - 15

Simplifying the left-hand side and the right-hand side of the equation, we obtain:

To remove all perfect squares from this expression, we need to find the perfect squares that divide into 45.

The prime factorization of 45 is:

45 = [tex]3^{2}[/tex] * 5

So, the perfect squares that divide into 45 are[tex]3^{2}[/tex] = 9.

To remove the perfect squares from 45y, we can factor out 9 from 45, and get:

45y = 9 * 5y

What is trigonometry?

The study of the relationships and characteristics of angles, triangles, and the trigonometric functions is the focus of the mathematic branch known as trigonometry (sine, cosine, tangent, cotangent, secant, and cosecant). It entails using algebraic methods and geometric principles to solve problems involving triangles and angles, such as measuring angles, computing triangle sides and angles, and analysing periodic events like waves and oscillations.

We use trigonometry to solve the problem

we have

tan (36) = opposite side/ adjacent side

tan(36) = opposite side / 12

Opposite side = tan(36) *12

Opposite side = 8.1 ft

Hence, the approximate height of the front bed 8.1ft
