The weight in pounds of the fourth dog, is 55 lbs.

What is weight?

The force exerted on an object by gravity is known as its weight. The gravitational force acting on the item is referred to as weight in several common textbooks. Some people refer to weight as a scalar quantity that measures the gravitational force's strength.

As given, Ben is walking with three dogs that weigh an average of 75 pounds each. Ben begins to walk with a fourth dog, and the average weight of the dogs decreases to 70 pounds.

The total weight of the first three dogs is 225 pounds.

This amount, plus the weight of the fourth dog, divided by total number of dogs, is the new average weight:

\(\frac{d+225}{4} = 70\\d + 225 = 280\\d = 280 - 225\\d = 55 lbs\)

Therefore, the weight of the fourth dog is 55 lbs.

Answer:

  (1/2, -3/4)

Step-by-step explanation:

You want to solve by substitution the equations ...

We notice that the term 2y shows up in both equations. That means we can use one of them to write an expression for 2y that we can use in the other equation.

Solving the second equation for 2y, we have ...

  2y = 5x -4 . . . . . add 5x to both sides

Using this expression for 2y in the first equation gives ...

  15x +(5x -4) = 6

  20x = 10 . . . . . . . . . add 4, collect terms

  x = 1/2 . . . . . . . . divide by 20, simplify

Now, we can use our expression above to find y:

  2y = 5x -4 = 5(1/2) -4

  2y = 5/2 -8/2 = -3/2 . . . . simplify

  y = -3/4 . . . . . . . . . . . . divide by 2

The solution is (x, y) = (1/2, -3/4).

__

Additional comment

The graph confirms this solution.

You can substitute anything that is convenient. For example, we could have rewritten the first equation to be ...

  -3(-5x) +2y = 6

Then we could solve the second equation for -5x: -5x = -2y -4 and make the substitution ...

  -3(-2y -4) +2y = 6

  8y +12 = 6 . . . . . simplify

  8y = -6 . . . . . . . subtract 12

  y = -6/8 = -3/4 . . . . divide by 8

You're probably told that you need an expression for one of the variables. Solving the second equation for y gives ...

  2y = 5x -4 . . . . . . add 5x to the second equation

  y = (5x -4)/2 . . . . . . expression for y

This always works. As we have seen, in some cases it is not necessary to go this far. It usually pays to look at what you have to work with before you develop a strategy for solving it.

Any negative number is an integer, that is not a whole number

The percentage win ratio for the winning of nominators X OR Y is 75%.

To calculate the percentage win ratio for the winning of nominators X OR Y, we need to consider their individual winning probabilities. For X, the winning percentage is 50%, and for Y, it is 25%.

X OR Y means either X wins or Y wins. Therefore, we sum up their individual winning percentages:

Percentage win ratio (X OR Y) = X's percentage + Y's percentage = 50% + 25% = 75%

X AND Y implies a scenario where both X and Y win together, which is not possible in this context as there can only be one winner for the position of team leader. So, the percentage win ratio for X AND Y is not applicable here.

The equation of the exponential model is f(x) = 3 * 0.2^x

The opposite of an exponential function is a logarithmic function. A log function and an exponential function both use the same base. An exponent is a logarithm. f(x) = bx is how the exponential function is expressed. The formula for the logarithmic function is f(x) = log base b of x.

Given a data set:

x                                        f(x)

−2                                      71

−1                                       13

 0                                       3

 1                                      0.6

 2                                     0.1

An exponential model is represented as:

f(x) = ab^x

When x= 0 and f(x) = 3;

We have:

ab^0 = 3

This gives

a = 3

When x= 1 and f(x) = 0.6

We have:

ab^1 = 0.6

This gives

ab = 0.6

Substitute 3 for a

3b = 0.6

Divide both sides by 3

b = 0.2

Substitute b = 0.2 and a =3 in f(x) = ab^x

f(x) = 3 * 0.2^x

Hence, the equation of the exponential model is f(x) = 3 * 0.2^x

1. Cartesian equation: y = 2x + 2

2. Straight line with slope 2 and y-intercept 2.

3. Tangent line equation: y - y₀ = 2(x - x₀)

Here are the calculations for the given problem:

Given:

x(t) = 1²t

y(t) = 2t + 2

1. To find the x-y Cartesian equation:

Substituting x(t) and y(t) into the equation y = 2x + 2:

y = 2(1²t) + 2

y = 2t + 2

2. To sketch the path for 0 ≤ t ≤ 4:

By substituting different values of t within the given range, we can obtain corresponding values for x and y to plot the points on a graph. The resulting points will form a straight line with a slope of 2 and a y-intercept of 2.

3. To find the equation of the tangent line:

Differentiating x(t) and y(t) with respect to t:

dx/dt = 1² = 1

dy/dt = 2

The slope of the tangent line is given by dy/dx = (dy/dt)/(dx/dt) = 2/1 = 2.

Using the point-slope form of a line, the equation of the tangent line at a given point (x₀, y₀) can be written as y - y₀ = m(x - x₀), where m represents the slope of the tangent line.

Step-by-step explanation:

Answer:

Kevin should do 15 shock replacements and 6 brake replacements every week to maximize his weekly income.

Step-by-step explanation:

Both jobs take the same amount of time to complete (2 hours), therefore, in order to maximize his income, Kevin should prioritize the job that gives him the greatest income, which is replacing shocks.

If each job takes 2 hours and he works at most 42 hours per week, Kevin can complete 21 jobs per week. He should aim to do as little break replacements as possible and as many shock replacements as possible to maximize income.

If he completes at least 6 break replacements, the remaining jobs should all be shock replacements:

\(S=21-6\\S=15\)

Kevin should do 15 shock replacements and 6 brake replacements every week to maximize his weekly income.

Kevin has been working as an auto-mechanic. For maximizing weekly income Kevin should do 6 breaks replacement and 4 shock replacements. The time required for performing both the tasks has been equal. Since the time required has been the same, to increase the income, the task resulting in more income has been prioritized

Given :

Since there have been more income with shock replacement, the brake replacement task has been prioritized.

The time Kevin works in a week has been 42 hours. Since each job takes 2 hours, the number of jobs he can perform has been 21 jobs.

The routine jobs of brake replacement performed by Kevin have been 6. Thus to increase his income, the rest jobs have been of shock replacement.

The number of shock replacement tasks performed by the Kevin =

= 21 - 6

= 15

The number of shock replacement jobs = 15.

Thus for increasing the income Kevin has to perform 6 brake replacement tasks and 15 shock replacement tasks.

Definitions =

Proxy voting = Proxy voting is when a shareholder delegates their voting rights to another person or entity, known as a proxy, to vote on their behalf. This can be done for various reasons, such as when a shareholder is unable to attend a meeting or wants to entrust their voting decisions to someone else. It does not directly relate to board seats being awarded in proportion to the votes received.

Board of Directors = The Board of Directors is a group of individuals elected or appointed to represent the shareholders and oversee the management of a company. They are responsible for making major decisions, setting company policies, and appointing senior executives. Each candidate for the board of directors is typically elected by a majority vote of the shareholders.

Preemptive right = Preemptive right, also known as the right of first refusal, is a privilege granted to existing shareholders of a company. It allows them to have the first opportunity to purchase additional shares before they are offered to the public. This right helps protect the ownership interests of existing shareholders by giving them the chance to maintain their proportional ownership in the company.

Straight-line voting = Straight-line voting is not a commonly used term in corporate governance. However, based on the given options, it seems to be referring to a voting system where each shareholder is entitled to one vote per share they own. This is the standard method of voting in most corporate elections, where each shareholder's voting power is directly proportional to their shareholding.

Cumulative voting = Cumulative voting is a voting method that allows shareholders to pool their votes and allocate them as they see fit among the candidates for the board of directors. It gives minority shareholders the opportunity to concentrate their votes on fewer candidates and increase their chances of electing a representative to the board. This mechanism helps to ensure a more proportional representation of shareholders on the board.
