The value of the stock after the increase of 1/4(fraction) using the addition expression is equal to $11.75. 

In Mathematics, a fraction is defined as the portion/part of the whole thing. A fraction consists of two parts, numerator and denominator. The number on the top is known as the numerator, and the number on the bottom is known as the denominator.

Given,

         The initial value of stock = $11.50

         Increase in stock ( in fraction) = 1/4

We know that earlier in the stock market the changes in values were indicated by fractions which represent portions of $1

Therefore,

               Increase in value of stock = 1/4 * $1

                                                         =  $0.25

Hence, 

          Value of stock after increase = $11.50 + $0.25

A formula answer is a mathematical expression or equation that provides a specific result or solution to a problem.

A formula is a mathematical equation or expression, or a set of them, which is used to calculate or predict a specific result or solution. They often involve a combination of numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division.

Formulas can be used in a wide range of fields such as science, engineering, finance, and statistics to make calculations and predictions based on known information. They can also be used to simplify complex calculations or to express complex relationships in a clear and concise way. They can be simple or complex, and are often represented using mathematical notation such as equations or graphs.

One example of a formula is the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

The formula for the Pythagorean theorem is: c^2 = a^2 + b^2 where c is the length of the hypotenuse and a and b are the lengths of the other two sides. This formula can be used to calculate the length of the hypotenuse in a right-angled triangle, given the lengths of the other two sides.

The equation that has 2 as its root is 2x² - 7x + 6 = 0 (option A)

The roots of a quadratic equation is equal to its solution.

If x = 2 is the solution of an equation, then f(2) = 0.

Let's check for the given functions:

A. 2x² - 7x + 6 = 0

f(2) = 2(2)² - 7(2)+ 6

f(2) = 2(4) - 14 + 6 = 0

Hence, x = 2 is its root.

B.  x² - 4x + 5 = 0

f(2) =  2² - 4(2) + 5

f(2) = 4 - 8 + 5 = 1

Since f(2) ≠ 0, hence 2 is not its root.

C. x² + 3x - 12 = 0

f(2) = 2² + 3(2) - 12

f(2) = 4 + 6 - 12 = -2

Since f(2) ≠ 0, hence 2 is not its root.

D. 3x² - 6x - 2 = 0

f(2) = 3(2)² - 6(2) - 2

f(2) = 12 - 12 - 2 = -2

Since f(2) ≠ 0, hence 2 is not its root.

Hence, the correct option is A.  2x² - 7x + 6 = 0

The measure of the other two angles of the quadrilateral are 15 and 85.

What are the angles of a quadrilateral?

Angles in a quadrilateral are the four angles that occur at each vertex within a four-sided shape; these angles are called interior angles of a quadrilateral. The sum of the interior angles of any quadrilateral is 360 360°. We can prove this using the angle sum of a triangle.

A quadrilateral is a polygon having four sides, four angles, and four vertices.  When we draw the diagonals to the quadrilateral, it forms two triangles. Both these triangles have an angle sum of 180°. Therefore, the total angle sum of the quadrilateral is 360°

Given, two angles of quadrilateral as  175° and 85°.

Let other 2 angles be x and y.

x + y + 175 + 85 = 360

x + y = 100

Given x/y = 3/17

x= 3/17(y)

So,

3y/17 + y = 100

20y = 1700

y = 85

x = 100 - 85 = 15

Hence other two angles of the quadrilateral are 15 and 85.

So, (3/10) ∫(0 to t) sin(2πt/5) dt would find the volume of inhaled air in the lungs at time t.

The function f(t) = (3/10)(sin(2πt/5)) is often used to model the rate of air flow into the lungs because it is cyclic, with a period of 5 seconds, and has a maximum value of 0.3 L/s. This function represents the rate of air flow into the lungs at any given time t.

To find the volume of inhaled air in the lungs at time t, we can integrate the function f(t) with respect to time. The volume of air inhaled at time t is the definite integral of f(t) from the start of inhalation (t = 0) to time t.

∫(0 to t) f(t) dt = (3/10) ∫(0 to t) sin(2πt/5) dt

The definite integral can be solved with proper limits, but the result is not in a closed form that can be expressed in terms of elementary functions.

In order to get the volume of inhaled air in the lungs at time t, we need to know the specific values of t and solve the definite integral with proper limits.

It's worth noting that this model is a simplified one and many other factors like breathing rate, lung capacity, and lung compliance could affect the actual volume of inhaled air in the lungs.

The time at which the car is 0.1 miles from the checkpoint is 95.1s and 108.7s.

The speed of the car is 53 miles per hour.

The distance of the car from the checkpoint is given by d = |1.5 - 53t|

To be 0.1 miles away from the checkpoint, the car has to travel 1.4 miles OR 1.6 miles. 

53 miles = 60 minutes 

1.4 miles = 1.4 / 53 × 60

= 1.5849056 minutes

= 1.5849056 × 60 seconds

= 95.1 seconds 

1.6 miles = 1.6 /53 × 60

= 1.8113207 minutes

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other

What is an equivalent ratios?

A ratio compares two quantities named as antecedent and consequent, by the means of division. For example, when we cook food, then each ingredient has to be added in a ratio. Thus, we can say, a ratio is used to express one quantity as a fraction of another quantity.

Two ratios are equivalent to each other if one of them can be expressed as the multiple of the other. Hence, to get the equivalent ratio of another ratio, we have to multiply the two quantities (antecedent and consequent) by the same number.

Given ratios are 2:1 and 3:1

we can write it as 2/1 and 3/1.

The lcm of 2 and 3 is 6.

Multiply denominator of both ratio with 6, we get

2/6 and 3/6 And we can see both the ratios are not equal.

Hence, there are not equivalent ratios.

4:1 and 8:3 are equivalent ratios -----> is false, because 4:1 is equivalent to 8:2

11:2 and 2:11 are equivalent ratios------> is false (because, are reciprocal ratios, not equivalent ratios)

A controlled experiment is a scientific test conducted under controlled conditions. That is, change only one (or a few) factors at a time and keep all others constant.

Control Experiment:

Controls eliminate alternative explanations for experimental results, particularly experimental error and experimenter bias. Many controls, like molecular markers used in SDS-PAGE experiments, are specific to the type of experiment being performed and may simply have the purpose of confirming that the instrument is functioning properly. I have. Choosing and using appropriate controls and ensuring that experimental results are valid (eg, no confounding variables) can be very difficult. Control measurements can also be used for other purposes. For example, measuring the background noise of a microphone in the absence of a signal allows the noise to be subtracted from later signal measurements to produce a higher quality processed signal.

For example, if a researcher fed a laboratory artificial sweetener to 60 laboratory rats and observed that 10 of them subsequently became ill, the underlying cause could be the sweetener itself or could be something else. Other variables that may not be immediately apparent can interfere with experimental design. For example, an artificial sweetener can be mixed with a diluent, and it could be the diluent that causes the effect.To see the effect of the diluent, he does the same test twice. A diluent with artificial sweeteners and a diluent-only version in the same way. Here the experiment is checked for diluent and the experimenter can distinguish between sweetener, diluent and no treatment. Controls are usually required when confounding factors cannot be easily separated from the primary treatment. For example, a tractor may need to be used to spread manure when there is no other practical way to spread it. The simplest solution is for the tractor to drive over the plot without spreading fertilizer and control the effects of tractor traffic.

The simplest types of controls are negative and positive controls, both of which are found in many different types of experiments. If both are successful, these two controls usually have the most latency. sufficient to eliminate significant confounding variables. That is, an experiment produces a negative result when a negative result is expected and a positive result when a positive result is expected.

In this scenario, if a computer was bought for $2350 and is being depreciated over 5 years, the annual depreciation is $470, and its value 3 years later would be $1410.

The straight-line method of depreciation is a method of calculating the decline in value of an asset over time. Using this method, an asset's value is spread evenly over its useful life.

In this scenario, if the computer was bought for $2350 and is being depreciated over 5 years, the annual depreciation is ($2350 / 5) = $470.

Three years later, the computer's value would be $2350 - ($470 x 3) = $1410. This is because the value of the computer is decreasing by $470 per year, and after three years, the total amount of depreciation would be $470 x 3 = $1410.

It's important to note that the straight-line method of depreciation is a simple method and it does not reflect the real-world scenario in which assets may have a higher value of depreciation in the initial years and less in the later years. But it's easy to calculate and use.

In conclusion, if an asset is depreciated using the straight-line method, its value decreases evenly over its useful life. It's important for businesses to understand the various methods of depreciation and choose the one that best suits their needs.

To find the total amount of milliliters of punch, we need to add together the amount of water, apple juice, and grape juice used to make it. Since the punch is made up of "water by volume" and "the rest is grape juice," we know that the ratio of water to grape juice is 1 : 1. If we know the amount of grape juice used in milliliters, we can use that to find the amount of water and apple juice used, and then add all three amounts together to find the total amount of milliliters of punch.

Let's say that "x" milliliters of grape juice were used to make the punch. Since the ratio of water to grape juice is 1 : 1, we know that the same amount of water, "x" milliliters, were used. To find the total amount of milliliters of water and grape juice, we add x + x = 2x milliliters.
