Jack needs to make at least $95 in tips on Sunday to reach an average of $19 per day.

Average = (Sum of all values) / (Number of values)

Average = ($19) / (7 days)

Average = ($19) / (7)

Average = $2.71

Sunday = ($2.71) x (7)

Sunday = $19.00 + $76.00

Sunday = $95.00

Jack is working as a waiter and needs to keep track of his tips. He wants to make an average of $19 per day and needs to figure out how much he needs to make on Sunday. To calculate this, he needs to first figure out the average he wants to make per day. For this, he needs to divide the amount he wants to make daily ($19) by the number of days he is working (7). This gives him an average of $2.71 per day. To get to the amount he needs to make on Sunday, he needs to multiply this average by the number of days he is working, which is 7. This gives him an amount of $19.00 + $76.00, which equals $95.00. Thus, Jack needs to make at least $95 in tips on Sunday to reach an average of $19 per day.

On solving the provided question, we can say that  x = central angle = 60 degrees, r = radius = 9 inches and L = 9.42

An angle is a form in Euclidean geometry made composed of two rays, called the angle's sides, that meet at a point in the middle known as the angle's vertex. In the plane where the rays are placed, two rays can produce an angle. An angle is also produced when two planes intersect. They're known as dihedral angles. In plane geometry, an angle is the form that two rays or lines with a common termination might take. The Latin word "angulus," which means "horn," is where the English word "angle" comes from. The two rays, also known as the sides of the angle, have a common termination known as the vertex.

x = central angle = 60 degrees

r = radius = 9 inches

L = arc length

[tex]L = (x/360)*2*pi*r\\L = (60/360)*2*pi*9\\L = 3*pi\\L = 9.42477796076938\\L = 9.42[/tex]

Using Pythagorean theorem, The value of cos(S) rounded to the nearest hundredth is approximately 0.78.

It is the simplest polygon and a key component in many branches of science and mathematics.

A triangle's three sides can be equilateral, isosceles, scalene, or any other combination of lengths and kinds. An isosceles triangle has a third side that is a different length from the other two sides, while an equilateral triangle has three sides that are all the same length. All three of the sides of a scalene triangle are different lengths.

In triangle STU, right angled at T, we have:

[tex]ST = 6UT = \sqrt{(22)}[/tex]

We can use the Pythagorean theorem to find the length of TU:

[tex]TU^2 = ST^2 + UT^2\\TU^2 = 6^2 + (\sqrt{(22)})^2\\TU^2 = 36 + 22\\TU^2 = 58\\TU = sqrt(58)\\[/tex]

Now, we can use the definition of cosine:

cos(S) = adjacent/hypotenuse

In this case, the adjacent side to angle S is ST and the hypotenuse is TU. Therefore:

[tex]cos(S) = ST/TU\\cos(S) = 6/\sqrt{(58)}[/tex]

To round to the nearest hundredth, we can divide 6 by the rounded value of sqrt(58):

cos(S) ≈ 0.78 (rounded to the nearest hundredth)

Therefore, the value of cos(S) rounded to the nearest hundredth is approximately 0.78.

The future value of the investment when interest is compounded continuously is; $3408.29

Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.

Given Data

P= $1500, r = 3.95%, t = 5 yr

To Calculate the number of periods: in this case we have 5*12= 60 months.

- The monthly interest rate, we have to divide the annual nominal rate by 12 (the number of periods in the year).

Then, we can calculate the future value as:

A = P (1 + r/n)^nt

A = 1500(1 + 3.95/365)(365)^(5)

P = 1500/ (1 + 0.00010137)^(5)

P = $3408.29

The future value when compounded monthly is $3408.29.

The difference in cost between a one-line ad and a four-line ad is $14.

What is percentage ?

Percentage can be defined as product of ratio of given value, total value and hundred.

To find how much Ben paid in sales tax, we need to first calculate the amount of the sales tax.

The sales tax is 9.5% of the purchase price of the car, which can be expressed as a decimal by dividing by 100:

Sales tax rate = 9.5% = 0.095

To find the amount of sales tax, we can multiply the purchase price by the sales tax rate

Sales tax = 0.095 x $25,500 = $2,422.50

Therefore, Ben paid $2,422.50 in sales tax.

The cost of an ad in a local paper is given by the piecewise function:

c(x) = 40, for x ≤ 5 (one-line ad)

c(x) = 40 + 7(x - 4), for x > 5 (four-line ad)

To find the difference in cost between a one-line ad and a four-line ad, we can subtract the cost of a one-line ad from the cost of a four-line ad:

c(6) - c(1) = (40 + 7(6 - 4)) - 40 = 14

Therefore, the difference in cost between a one-line ad and a four-line ad is $14.

Answer:

Step-by-step explanation:

here is a step-by-step explanation for finding the equation of the line that passes through the points (0, -3) and (0, -8):

Identify the two points that the line passes through: (0, -3) and (0, -8)

Determine the slope of the line: The slope of a line is given by the formula "rise over run," or (y2 - y1) / (x2 - x1). However, in this case, the line is vertical and has an undefined slope.

Write the equation of the line in slope-intercept form: y = mx + b, where "m" is the slope and "b" is the y-intercept. Since the slope of the line is undefined, the equation of the line cannot be written in slope-intercept form.

Write the equation of the line in point-slope form: y - y1 = m(x - x1), where "m" is the slope and (x1, y1) is a point on the line. Since the slope of the line is undefined, the equation of the line cannot be written in point-slope form.

Write the equation of the line as an x-intercept form: The x-intercept form of a line is given by the equation x = a, where "a" is the x-coordinate of the point that the line passes through. In this case, the line passes through the point (0, -3) and (0, -8), so the equation of the line is x = 0.

So, the equation of the line that passes through the points (0, -3) and (0, -8) is x = 0.

The driver increased altitude is 517 feet.

A right triangle is a triangle with one of its angles as 90 degrees. The sum of angles in a triangle is 180 degrees.

Therefore, the road is inclined at an angle of 6 degrees.  After driving 4950 feet along this​ road, let's find the altitude as follows:

using trigonometric ratios,

sin 6° = opposite / hypotenuse

Therefore,

sin 6° = a / 4950

cross multiply'

a = 4950 sin 6°

a = 4950 × 0.10452846326

a = 517.415893175

Therefore,

a = 517 feet

Altitude = 517 feet

Using the unitary method we found that the amount that Bill should receive is $500 and the amount that his boss owes him is $26.

What is meant by the unitary method?

The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value. Once we have determined the value of a single unit, we may multiply that value by the number of units needed to determine the value of the other units. The concept of ratio and proportion is mostly applied using this way. Recognizing the units and values is crucial when using the unitary technique to a problem.

Given,

    Money received for each document = 25 cents

  Number of documents prepared by Bill = 2000

  The amount he received = $474

a) The correct total pay that Bill should receive = 2000*25 = 50,000cents

   Using the unitary method,

                   1 dollar = 100 cents

                  50,000 cents = 50000/100 = $500

b) The amount that his boss owes him = 500 - 474 = $26

The probability of rolling a sum of 11 on the first roll of two dice is 1/36, as there is only one combination of dice that can add up to 11 (a 5 and a 6).

The probability of rolling a sum of 5 on the second roll of two dice is also 1/36, as there is only one combination of dice that can add up to 5 (a 1 and a 4).

The probability of two independent events occurring is equal to the product of their individual probabilities. So, the probability of rolling a sum of 11 on the first roll and a sum of 5 on the second roll is:

1/36 * 1/36 = 1/1296

So, the probability of rolling a sum of 11 on the first roll and a sum of 5 on the second roll is 1/1296.

Using the equation provided, you can estimate the number of hours worked each week for a student with a GPA of 2.21. The equation can be rearranged to solve for h, the number of hours worked each week.

h = (g - 3.04) / (0.012 + 0.0007)

Plugging in the GPA of 2.21, we get:

h = (2.21 - 3.04) / (0.012 + 0.0007)

h = -4.83 hours

Therefore, a student with a GPA of 2.21 would need to work an average of -4.83 hours per week in order to achieve that GPA.
