Answer: see attached image

Step-by-step explanation:

since the distance between each number is split into fourths, that is the interval it is increasing.

5/2 simplified is 2 and 1/2. so you go 2 tick marks after the 2.

-2 and 3/4 goes 3/4 (3 tickmarks) after the -2.

Answer:

Maliks fruit salad will taste more melony

Step-by-step explanation:

To determine whose fruit salad will taste more "melony," we can calculate the percentage of melon in each fruit salad for Aisha and Malik.

For Aisha's fruit salad:

Total cups of fruit = 4 cups of melon + 1 cup of apple = 5 cups

Percentage of melon = (4 cups of melon / 5 cups of total fruit) x 100%

For Malik's fruit salad:

Total cups of fruit = 13 cups of melon + 3 cups of apple = 16 cups

Percentage of melon = (13 cups of melon / 16 cups of total fruit) x 100%

Now we can calculate the percentages:

Aisha's percentage of melon:

(4 cups of melon / 5 cups of total fruit) x 100% = 80%

Malik's percentage of melon:

(13 cups of melon / 16 cups of total fruit) x 100% ≈ 81.25%

Based on the calculations, Malik's fruit salad has a higher percentage of melon (81.25%) compared to Aisha's fruit salad (80%). Therefore, Malik's fruit salad is likely to taste more "melony" compared to Aisha's fruit salad.

To calculate the gross profit, we need to subtract the cost of goods sold (COGS) from the revenue generated by sales. The revenue generated by sales can be found by multiplying the number of printers sold by the selling price of each printer, which is $1,750.

Revenue generated by sales = 26 x $1,750 = $45,500

The cost of goods sold for each printer is $975, so the total cost of goods sold for all 26 printers is:

Total cost of goods sold = 26 x $975 = $25,350

Therefore, the gross profit can be calculated as:

Gross profit = Revenue generated by sales - Total cost of goods sold

Gross profit = $45,500 - $25,350

Gross profit = $20,150

The gross profit is $20,150.

To calculate the net income, we need to subtract all operating expenses from the gross profit. The operating expenses include your salary ($3,000/month), advertising ($50/month), and office lease ($550/month).

Total operating expenses = $3,000 + $50 + $550

Total operating expenses = $3,600

Therefore, the net income can be calculated as:

Net income = Gross profit - Total operating expenses

Net income = $20,150 - $3,600

Net income = $16,550

The net income is $16,550.

In summary, the gross profit is the revenue generated by sales minus the cost of goods sold, which in this case is $20,150. The net income is the gross profit minus all operating expenses, which in this case is $16,550.

The periodic deposit required to reach the financial goal of $1,000,000 in 45 years with a 6.75% annual interest rate compounded monthly is approximately $541.05.

And,  Amount $292,593.00 comes from deposits and $707,407.00 comes from interest.

For the periodic deposit, we can use the formula:

P = (FV × r) / ((1 + r)ⁿ - 1)

where P is the periodic deposit, FV is the financial goal, r is the interest rate per period, and n is the total number of periods.

Using the given values, we get:

P = ($1,000,000 0.0675) / ((1 + 0.0675/12)^(45x12) - 1)

P ≈ $541.05

So, the periodic deposit required to reach the financial goal of $1,000,000 in 45 years with a 6.75% annual interest rate compounded monthly is approximately $541.05.

And, To determine how much of the financial goal comes from deposits and how much comes from interest, we can calculate the total amount of deposits made over the 45-year period:

Hence, Total deposits is,

P n = $541.05 (45 x 12)

      ≈ $292,593.00

Then we can subtract this amount from the financial goal to get the amount that comes from interest:

Amount from interest = FV - Total deposits

= $1,000,000 - $292,593.00

≈ $707,407.00

So , Amount $292,593.00 comes from deposits and $707,407.00 comes from interest.

Step-by-step explanation:

You want to determine the number of solutions to three different systems of equations.

A linear equation is written in standard form when the coefficients are mutually prime, and the leading coefficient is positive:

  ax +by = c . . . . . . GCF(a, b, c) = 1, a > 0

The equations are easiest to compare when they are all written in standard form.

A system will have an infinite number of solutions when the equations are identical.

A system will have zero solutions when it reduces to ...

  (non-zero constant) = 0

A system will have one solution when the equations are different.

A factor of 2 can be removed from the first equation:

  2x -3y = 5

A factor of 3 can be removed from the second equation:

  2x -3y = 5

These equations are identical, so have infinitely many solutions.

Multiplying the first equation by 2 gives ...

  2y = -3x +6

Adding 3x, we have ...

  3x +2y = 6

When we subtract the second equation from this, we get ...

  (3x +2y) -(3x +2y) = (6) -(3)

  0 = 3

These equations have no solution.

These equations are already in standard form, and are different. This system has one solution.

(The exact solution is (x, y) = (0.48, 3.36).)

The function that would match the graph shown below is given as follows:

y = -5(x³ + 7x² + 8x - 16).

The function is defined using the Factor Theorem, as we have the x-intercepts of the graph, hence we can write the function as a product of it's linear factors.

Considering the x-intercepts, the roots are given as follows:

Hence, considering the leading coefficient a, the function is defined as follows:

y = a(x + 4)²(x - 1)

y = a(x² + 8x + 16)(x - 1)

y = a(x³ + 7x² + 8x - 16).

When x = 0, y = 80, hence the leading coefficient a is obtained as follows:

-16a = 80

a = -5.

Hence the function is:

y = -5(x³ + 7x² + 8x - 16).

Answer:

y^2 = 3, so y = -√3

The graph that represents the equation is:

The graph shows an upward parabola with vertex (2, -6) and passes through (-1, 7), (0, 0), (4, 0), and (5, 7).

Option B is the correct answer.

We have,

The equation y = (3/2)x² - 6x represents an upward parabola since the coefficient of x² is positive.

Now,

The vertex of the parabola.

x = -b/2a,

where a and b are the coefficients of x² and x, respectively.

So,

a = 3/2 and b = -6

x = -(-6)/(2(3/2)) = 6/3 = 2.

Plugging x = 2 into the equation,

We get y = 3/2(2)² - 6(2) = -6,

so the vertex is (2, -6).

We can eliminate options A and C since their vertices are not (2, -6).

Now,

To check which of the remaining options fits the equation, we can plug in the given points and see if they satisfy the equation.

Option B gives:

When x = -1, y = 3/2(-1)² - 6(-1) = 7

When x = 0, y = 3/2(0)² - 6(0) = 0

When x = 4, y = 3/2(4)² - 6(4) = 0

When x = 5, y = 3/2(5)² - 6(5) = 7.5

So option B fits the equation, and is the graph that represents

y = (3/2)x² - 6x.

Therefore,

The graph that represents the equation is:

The graph shows an upward parabola with vertex (2, -6) and passes through (-1, 7), (0, 0), (4, 0), and (5, 7).

Team B has 33 players that weigh more than 200 pounds.

To calculate the percentage, divide the amount by the total value and multiply the result by 100. The percentage is calculated using the formula: (value/total value)100%.

When 80% of the players weigh more than 200 pounds, 20% of the players weigh less than 200 pounds.

We can start by locating 20% of the players:

20% of 41 = 0.20 x 41 = 8.2

So we can guess that there are about 8 players weighing 200 pounds or fewer.

We may subtract this estimate from the total number of participants to obtain the number of players who weigh more than 200 pounds:

Both solutions are valid, and depending on the context of the problem, one or both solutions may be useful in solving for different parameters, such as the maximum height or the time of flight of the projectile.

Step-by-step explanation:

In a projectile motion formula, such as the one that describes the height of an object in motion as a function of time, there are two solutions because the object can reach the same height at two different times during its trajectory.

The negative solution represents the time it takes for the object to reach its maximum height and then start falling back down to the ground. The positive solution represents the time it takes for the object to reach the same height on its way up.

So, both solutions are valid, and depending on the context of the problem, one or both solutions may be useful in solving for different parameters, such as the maximum height or the time of flight of the projectile.

If the total cost is $39.80, then the number of miles driven is 66 miles.

Here we know that  a truck rental costs $20 plus $0.30 for each mile driven.

Then we can model this with a linear equation where the y-intercept is 20, and the slope is 0.30 (where the independent variable will be the number of miles driven).

Then the total cost is modeled by the linear equation:

y = 20 + 0.3*x

If the total cost is $39.80, then we can solve:

39.8 = 20 + 0.3*x

39.8 - 20 = 0.3*x
