Answer:

2day I think might not be right

The number of days it will take him to reach his goal is 6.5 days.

Given that, Marty decided he wants to run a 5 km race.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of days be x.

He is starting by running \(1\frac{3}{4} =\frac{7}{4}\) km and adding 1/2km each day.

Now, 7/4 +1/2 x= 5

⇒ 1/2 x= 5-7/4

⇒ 1/2 x=13/4

⇒ x=6.5 days

Therefore, the number of days it will take him to reach his goal is 6.5 days.

Answer:

Step-by-step explanation:

Answer:

Ok, so slope is basically the steepness of the line, and intercept is when it crosses the x or y axis.

Step-by-step explanation:

To identify the slope, find two points on the line, then use this equation to find the slope: \(\frac{y2 - y1}{x2 - x1}\), where x1 and y1 are the coordinates of the first point on the line, and x2 and y2 are the coordinates of the second point on the line. y2 - y1 is called the rise, and x2 - x1 is called the run. Then, to find the intercept (commonly the y-intercept), you must find the point at which the line crosses the axis. This is the easiest part because you just need to find a point on the axis. When you need to find the y-intercept, look for where the line crosses the x-axis, and when you need to find the x-intercept, look for where the line crosses the y-axis.

Answer:

  addition property of equality

Step-by-step explanation:

You want the justification for step 1 in the solution process for -22 - x = 14 + 6x.

No solution process steps are shown, but we can speculate what they might be.

The goal is to separate constant terms and variable terms. This can be done several ways, but generally consists of adding the same thing to both sides of the equation.

Often, you're told to collect the variable terms first. Some prefer to do that so the variable terms are on the left side of the equal sign. Others prefer to do that so the result has a positive coefficient for the variable term. Taking the latter tack, we want to add x (the opposite of -x) to both sides of the equation:

  -22 -x +x = 14 +6x +x . . . . . x added to both sides

  -22 = 14 +7x . . . . . . . simplified

The justification for this step is the addition property of equality. That property allows you to add the same thing to both sides of an equation without changing the values of the variables.

__

Additional comment

Step 2 would be to add -14 to both sides, giving you ...

  -36 = 7x . . . . . . . . add -14; addition property of equality

If you like, you can do both of these additions in one step:

  -22 -x +(x -14) = 14 +6x +(x -14) . . . add(x -14); addition property of equality

  -36 = 7x . . . . . . simplified

Step 3 is to divide by the coefficient of the variable.

  -36/7 = (7x)/7 . . . . division property of equality

  -5 1/7 = x . . . . . . . simplified. This is the solution.

The usual procedure takes 3 steps, so this is called a "3-step equation."

Note that we choose for the variable coefficient to be positive, because we judge arithmetic with positive numbers to be less error-prone. If you collect the variable terms on the left, you get ...

   -7x = 36

so have to divide by -7. This should not be an issue if you're careful with your arithmetic, but many find dealing with negative numbers to be a challenge.

Using the multiplier formula, the eventual change in aggregate expenditure due to the inflow of R10 billion into South Africa and using the marginal propensity to consume (MPC) is R6 billion.

The multiplier formula is used to compute the amount of new income generated from the flow of extra income.

The multiplier formula uses the MPS (marginal propensity to save) to compute the multiplier as follows:

M = 1 / MPS

The marginal propensity to save gives the proportion of income that will be saved.

The marginal propensity to save (MPS) = 0.4

M = 1 / MPS

M = 1/0.4)

= 2.5

Change in aggregate expenditure = R25 billion (2.5 x R10 billion)

Thus, we expect the aggregate expenditure in South Africa to increase by R25 billion following the inflow of R10 billion investment.

Among the given answer choices, the correct option that represents this range is "0 100 200 none of the answer choices".

To determine the range of the number of RVs that need to be sold each month for the company to make a profit, we need to consider the profit function and find the values of x that result in a positive profit.

The profit function is given by P(x) = -50x + 20,000x - 1,500,000.

To make a profit, the value of P(x) must be greater than zero (P(x) > 0). We can set up the inequality:

-50x + 20,000x - 1,500,000 > 0.

Combining like terms, we have:

19,950x - 1,500,000 > 0.

Now, let's solve this inequality for x:

19,950x > 1,500,000.

Dividing both sides by 19,950, we get:

x > 1,500,000 / 19,950.

Simplifying the right side, we have:

x > 75.

The range of the number of RVs that need to be sold each month for the company to make a profit is x > 75.

We are to find the value of y

Answer:

my brain exploded trying to answer it sorry

Step-by-step explanation:

Answer:

y = ½x

_____

k = ½

Step-by-step explanation:

[# of donuts] 2 → [total price] $1

[# of donuts] 12 → [total price] $6

[# of donuts] 3 → [total price] $1.50

[# of donuts] 7 → [total price] $3.50

Because price is the dependent variable, it is the y value. And since the price is the y variable, the donuts must be the x value.

Because the price is ½ the # of donuts, y is ½ x which means y = ½x and k = ½.

An estimate of the mean age of these employees is 25.9 years.

We are given that;

The frequency table

Now,

To work out an estimate of the mean age of these employees, we can use the formula:

mean = (sum of (frequency x midpoint)) / (sum of frequency)

We can calculate the midpoints of each class interval by adding the lower and upper limits and dividing by 2:

(18 + 20) / 2 = 19 (20 + 22) / 2 = 21 (22 + 24) / 2 = 23 (24 + 26) / 2 = 25

Using these midpoints and the frequencies given in the table, we can calculate the sum of (frequency x midpoint):

3 x 19 + 2 x 21 + 7 x 23 + 8 x 25 = 3 x 19 + 2 x 21 + 7 x 23 + 8 x 25 = 518

We can calculate the sum of frequency by adding up all the frequencies:

3 + 2 + 7 + 8 = 20

Now we can substitute these values into the formula for mean:

mean = (sum of (frequency x midpoint)) / (sum of frequency) mean = (518) / (20) mean = 25.9

Therefore, by the frequency the answer will be 25.9 years.

Transversal line :

                             A transversal is a line that crosses two or more other lines.

given,

     ∠TLN = (3x - 18)°

    ∠MZQ = (5x + 14)°

    ∠NLM = y°

Now,

         ∠MZP + ∠MZQ = 180°  (Linear Pair)

        ∠MZP  = 180° - ∠MZQ  ...........(I)

again,

          ∠NLM + ∠TLN  =180°  ...........(II)      (Linear Pair)

  As,         ∠TLN = ∠MZP  (Corresponding Angle)

             (3x - 18)° =  180° - ∠MZQ  

           (3x - 18)° = 180° - (5x + 14)°

         3x + 5x  = 180° - 14° + 18°

           8x = 184°

           x = 184 / 8

          x = 23°

      From (II),

      ∠NLM + ∠TLN  =180°

    y° + 3x - 18° = 180°

 y = 180 - 3x + 18

Answer:

A = \(\frac{3}{4}\) \(\sqrt[3]{B}\)

Step-by-step explanation:

Given A varies directly as \(\sqrt[3]{B}\) then the equation relating them is

A = k \(\sqrt[3]{B}\) ← k is the constant of variation

To find k use the condition A = 3 when B = 64 , then

3 = k \(\sqrt[3]{64}\) = 4k ( divide both sides by 4 )

\(\frac{3}{4}\) = k

A = \(\frac{3}{4}\) \(\sqrt[3]{B}\) ← equation of variation

The solution of the system of equations is (8, 11).

We know that one of the equations of the system is:

y = x + 3

And the other line passes through the points (3, 1) and (4, 3), then the slope of that line is:

a = (3 - 1)/(4 - 3) = 2

So the line is something like:

y = 2*x + b

To find the value of b, the y-intercept, we can replace the values of one of the points.

I will use (3, 1)

1 = 2*3 + b

1 = 6 + b

1 - 6 = b

-5 = b

So the other line is y = 2x - 5

Then the system of equations is:

y = x + 3

y = 2x - 5

Now we can solve the system:

x + 3 =2x - 5

3 + 5 = 2x -x

8  =x

Alijah's taxable income puts him in the first tax bracket, over $8,350 but not surpassing $33,950. Hence, his tax due is a base of $835 plus 15% of the income that exceeds $8,350. This results in a total tax payable of $850. Option B is the correct answer.

Alijah's taxable income falls within the first bracket of the tax table given, being over $8,350 but not over $33,950.

This bracket requires him to pay a tax of $835.00 plus 15% of the amount over $8,350.

He has a surplus of $100 over the $8,350 threshold (i.e., $8,450 - $8,350), and 15% of $100 equals $15.

Therefore, the total tax he owes would be the fixed amount of $835.00 plus the $15.00 calculated, which sums up to $850.00.

Thus, looking at the provided options, option B ($850.00) would be the correct answer.
