Andy can set up a maximum of 12 tables, each with 3 servings of tacos and 3 servings of nachos.

Let's assume that there are a limit of n servings per table. We need to get the greatest number of n that divides both 21 and 15 without leaving a remnant because Andy doesn't want any leftover tacos or nachos. In comparison to the factors of 15, which are 1, 3, 5, and 15, the factors of 21 are 1, 3, 7, and 21. Three is the highest number that divides both 21 and 15.

Thus, a maximum of three dishes can be placed on each table. We divide the total servings by the maximum servings per table to get how many tables Andy can set up:

Servings total: 21 + 15 = 36

3 serves maximum per table.

Amount of tables = Total Servings / Maximum Servings Per Table = 36 / 3 = 12

Hence, Andy can only put up a maximum of 12 tables, each with 3 tacos and 3 nachos.

As per the given percentage, the original price to be $180.00.

Let's begin by defining what percentage means. A percentage is a fraction that represents a portion of a whole expressed as a fraction of 100. For example, 25% can be written as 25/100 or 0.25 as a decimal.

Now, let's apply this concept to the problem. We know that the original price increased by 25%, which means the new price is 125% of the original price. We can represent this mathematically as:

New price = Original price + 25% of the original price

125% of the original price = Original price + 25% of the original price

1.25 x Original price = Original price + 0.25 x Original price

1.25 x Original price = 1.25 x Original price

Original price = (225.00 / 1.25)

Therefore, the original price was $180.00.

The area will rise by a factor of four if we double the base and height of a trapezoid.

A quadrilateral with a single set of parallel sides is referred to as a trapezoid. The parallel and non-parallel sides are referred to as bases and legs, respectively. The distance between the bases of a trapezoid measured perpendicularly is its height.

The formula for a trapezoid's area is:

Area is equal to (base1+base2)*height / 2.

Considering that the height is 6 millimeters, the first base is 5 millimeters, and the secondary base is 7 millimeters, we may determine the trapezoid's initial area as follows:

Area = 1/2 *(5 + 7)* 6 = 36 sq. mm

Doubling the height and both bases:

New base 1 = 2 * 5 = 10 mm

New base 2 = 2 * 7 = 14 mm

New height = 2 * 6 = 12 mm

The new area of such trapezoid can be calculated using the same formula:

New Area = 1/2* (10 + 14) * 12 = 144 sq. mm

When we compare the new area to the old area, we are able to see that the new area has been four times bigger.

So, if the base and height of just a trapezoid are both doubled, the area will grow by a factor four.

The solutions of x1 = 7 and x2 = -3 with x1 through solving the quadratic  equation x²−4x−21=0 by factoring

The equation :x² - 4x - 21 = 0, solve it by factoring it.The first step is to find two numbers that will multiply to give us -21 and add up to -4. These numbers are -7 and 3.So, we rewrite the equation using -7 and 3 instead of  -4x:x² - 7x + 3x - 21 = 0.

Group the first two terms and the last two terms: x(x - 7) + 3(x - 7) = 0.

Factor out the common factor of (x - 7): (x - 7)(x + 3) = 0.

Now, we have two factors that when multiplied, give us zero. This means that either (x - 7) = 0 or (x + 3) = 0.

Solving for x, we get: x = 7 or x = -3.

The solutions are x1 = 7 and x2 = -3.The equation x² - 4x - 21 = 0 can be solved by factoring it. To factor this equation, we first find two numbers that will multiply to give us -21 and add up to -4. These numbers are -7 and 3. Then we rewrite the equation using -7 and 3 instead of -4x.

The resulting equation is x² - 7x + 3x - 21 = 0.

Next, we group the first two terms and the last two terms to get x(x - 7) + 3(x - 7) = 0.

We factor out the common factor of (x - 7) to get (x - 7)(x + 3) = 0.

We then solve for x to get x = 7 or x = -3. Therefore, the solutions are x1 = 7 and x2 = -3.

The expression for the amount of change Zina should receive would then be 20 - (0.30 x 10) = 17.00. This means that Zina should receive 17.00 in change from the clerk.

What is amount?

Amount is the quantity or amount of something that is available, measurable, or given. It is a numerical value. Amount can refer to a quantity of money, goods, or services that is owed, requested, or given. It can also refer to the total cost of items or services. Amounts can be measured in both the physical and digital world. Amount is used in accounting, finance, and other fields to measure and keep track of assets and liabilities.

The expression that represents the amount of change Zina should receive is 20 - (0.30p). This expression takes the original amount of money given to the clerk, twenty dollars, and subtracts out the total cost of the bananas, which is 0.30p. The 'p' in this expression represents the number of pounds of bananas Zina purchased.

To determine the amount of change Zina should receive, the clerk must first calculate the total cost of the bananas. This is done by multiplying the number of pounds of bananas purchased by the cost per pound. Once the total cost of the bananas is calculated, it is then subtracted from the twenty dollars given. The resulting number is the amount of change Zina should receive.

For example, if Zina purchased 10 pounds of bananas at 30 cents per pound, the total cost of the bananas would be 10 x 0.30 = 3.00. The expression for the amount of change Zina should receive would then be 20 - (0.30 x 10) = 17.00. This means that Zina should receive 17.00 in change from the clerk.

The square root of 22 is an irrational number, which means it cannot be expressed exactly as a finite decimal or a fraction. However, we can approximate it by finding the whole number that is closest to it.

To do this, we can use a calculator or estimation. For example, we can guess that the square root of 22 is between 4 and 5, since 4 squared is 16 and 5 squared is 25. Then we can try averaging these two numbers:

(4 + 5) / 2 = 4.5

This means that 4.5 is an approximate value of the square root of 22. The nearest whole number to 4.5 is 5, so we can say that the whole number nearest to the square root of 22 is 5.

The given data shows that in 2000, the population of a country was approximately 6.19 million, and by 2050, it is projected to grow to 10 million. The exponential growth model can be represented as:

A = A0e^{kt}

Where A0 = 6.19 (initial population in 2000), A = 10 (projected population in 2050), T = 50 - 00 = 50 years (time period between 2000 and 2050).

Substituting the values in the formula, we get:

10 = 6.19 e^{k × 50}

Solving for k:

e^{k × 50} = 10/6.19

k × 50 = ln(10/6.19)

k = ln(10/6.19) / 50

k = 0.0169

Therefore, the population of the country will be given by A = 6.19 e^{0.0169t} where t represents the time in years after 2000.

Larry's burn rate, which represents the amount of money he spent per unit of time, is $2,600 per month based on the starting balance of $17,300 and the ending balance of $14,700.

Larry's burn rate can be calculated as the amount of money he spent per unit of time, which is usually expressed as a monthly or annual rate. To calculate his burn rate based on the given information, we need to know the time period for which the difference between the starting and ending balances represents.

Assuming that the starting balance of $17,300 represents the beginning of a month or some other specific time period, and that the ending balance of $14,700 represents the end of the same time period, we can calculate Larry's burn rate as follows:

Burn rate = (Starting balance - Ending balance) / Time period

If we assume that the time period is one month, then:

Burn rate = ($17,300 - $14,700) / 1 month = $2,600 per month

Therefore, Larry's burn rate is $2,600 per month. This means that he spent an average of $2,600 per month to run his shoe store during the time period in question.

Answer:

This function has no zeroes

Step-by-step explanation:

To understand this problem we need to first understand what the zeroes of a function is; the zeroes of a function is the point at which the y value of a solution is equal to zero. So in this scenario all we need to do is plug 0 in for y:

[tex]0 = x^2 +49[/tex]

Subtract 49 from both sides:

[tex]-49 = x^2[/tex]

Now we can notice that [tex]x^2[/tex] is equal to -49; to our surprise there is no possible value for [tex]x^2[/tex] to be equal to a negative number. Therefore this function has no roots.

Step-by-step explanation:

a zero of a function means what value of x causes a functional value of 0 ?

so,

0 = x² + 49

-49 = x²

x = ±sqrt(-49)

this tells us that there is no solution in real numbers, because no square of any real number can be negative.

but the function still has 2 zeroes. they are numbers of the set of imaginary or complex numbers.

that means they base on the square root of -1, called i.

x = ±sqrt(49×-1) = ±7×sqrt(-1) = ±7i

It will take 55 days to finish the renovation with 25 men.

If 34 men can finish the renovation in 40 days, we can say that the number of men is inversely proportional to the number of days needed to finish the work. Therefore, we can write:

Number of men × Number of days = Constant

We can find the value of the constant by using the given information:

34 men × 40 days = 1360

This means that the constant is equal to 1360.

If 9 men withdraw before the work started, then the number of men who will work on the renovation is 34 - 9 = 25.

We can now use the constant to find the number of days needed to finish the renovation with 25 men:

The overall length of the molding can be calculated by multiplying the length of each piece by the number of pieces, for example, if Zach needs to cut wooden molding into 9 pieces that are each half a yard long:

Total length equals each piece's length times the number of parts.

Overall length is 9 + (1/2 yard)

length overall: 9 2 yards

We can divide 9 by 2 and write the outcome as a mixed number to represent this:

with a residue of 1, 9 2 = 4

Zach has to cut the wooden molding into 9 sections, resulting in a total length of 4 1/2 yards in various numbers.
