The  least positive multiple of 199 is still 199

To find the least positive multiple of 199, we can start by multiplying 199 by 1, 2, 3, and so on until we find a multiple that is a positive integer.

199 x 1 = 199

199 x 2 = 398

199 x 3 = 597

199 x 4 = 796

Notice that the product of 199 and any positive integer greater than 1 will have at least three digits. Therefore, the least positive multiple of 199 is 199 itself.

Therefore, the least positive multiple of 199 is 199.

Tabi's bill includes $248.94 in charges and $34.99 in interest.

Let x be the amount of interest that Tabi was charged, in dollars.

According to the problem, the new charges are $213.95 more than the interest, so the amount of new charges is x + $213.95.

The total bill, which includes the charges and interest, is $283.93.

Therefore, we can write an equation:

x + (x + $213.95) = $283.93

Simplifying and solving for x, we get:

2x + $213.95 = $283.93

2x = $69.98

x = $34.99

So the amount of interest charged is $34.99.

To find the amount of charges, we can use the equation for new charges:

x + $213.95 = $34.99 + $213.95 = $248.94

So the amount of charges is $248.94.

Therefore, Tabi's bill includes $248.94 in charges and $34.99 in interest.

Answer:

[tex]x=44[/tex]

Step-by-step explanation:

lets say X is the cookies Ms. Jans Brought to her class
first she put half of then in the morning (that is [tex]x/2[/tex] of her cookies)
then she gave out 12 more. That is 12 less cookies.
the total cookies left is the total amount minus the half, minus the 12 cookies:
[tex]x-x/2-12=10[/tex]
From this equation we can solve for X
[tex]x/2=10+12[/tex]

 [tex]x=2(22)\\[/tex]

[tex]x=44[/tex]
Just for check, if she brought 44 cookies, and put 22 (half of then), she still have 22 cookies, then she 12 more, then only 10 are left. So 44 is the answer.

The correct option is (b) i.e. the total perimeter of the fence is 7x + y − 4 feet.

What is Perimeter?

Perimeter is the total length of the boundary or outer edge of a two-dimensional shape, such as a polygon, circle, or ellipse. It is the sum of the lengths of all the sides or arcs that make up the shape. For example, the perimeter of a square is the sum of the lengths of all its sides, while the perimeter of a circle is the circumference, which is the distance around the circle. The perimeter is often measured in units such as centimeters, meters, or feet, depending on the context of the problem.

Given : sides of the fence

            s₁ = 4x + 5

            s₂ =  y − 7

            s₃ = 3x − 2

We know that, perimeter of a triangle is sum of all three sides.

So, Perimeter of the fence =  s₁+ s₂+ s₃

                                            = 4x + 5 + y − 7 + 3x − 2

                                            = 7x + y - 4 ft.

Answer:

Step-by-step explanation:

I'm sorry, but I cannot accurately calculate the driver's average speed without additional information such as the distance traveled and the time taken.

However, I can help you calculate the cost of fuel if the driver fills up half of the tank's capacity:

Half of the tank's capacity is 28/2 = 14 litres.

The cost of fuel per litre is R17.98.

Therefore, the cost of filling up half the tank is 14 x R17.98 = R251.72.

So, if the price of fuel is R17.98 per litre and the driver fills up half the tank, they will pay R251.72 for fuel.

Answer:

  (a)  65.85 km²

Step-by-step explanation:

You want the area of a sector with radius 7 km and central angle 154°.

The formula for the area of a sector is ...

  A = 1/2r²θ . . . . where r is the radius and θ is the central angle in radians

  A = 1/2(7 km)²(154·π/180) ≈ 65.85 km²

The area of the shaded sector is about 65.85 square km.

Additional comment

The last two answer choices can be eliminated because their units are distance units, not area units.

The area of the circle is πr², about 154 km². The shaded part is less than half, but somewhat more than 1/7, so will be less than 77 and more than 22 km². For this problem, a rough estimate of the area can tell you which is the reasonable answer choice.

The statement " If a and x are positive numbers and a ≠ 1, then[tex]log_a(x^r) = r * log_a(x)[/tex] for any real number r" is true .

To prove the equation, we can start with the definition of logarithms:

[tex]log_a(x) = y[/tex] if and only if [tex]a^y = x[/tex]

Using this definition, we can rewrite both sides of the equation as exponents:

[tex]log_a(x^r) = y[/tex] if and only if [tex]a^y = x^r[/tex]

[tex]r * log_a(x) = y[/tex] if and only [tex]a^y = x^r[/tex]

Since [tex]a^y = x^r[/tex] in both case, we have:

[tex]log_a(x^r) = r * log_a(x)[/tex]

Therefore, the equation [tex]log_a(x^r) = r * log_a(x)[/tex] holds for any positive numbers a and x (where a ≠ 1) and any real number r.

The total number of seats available for the baseball game can be calculated by adding the number of box and club seats available whch is found to be 25,200.

The game of baseball can be used to teach various mathematical concepts, such as probability, statistics, graphing, estimation, and basic arithmetic. The game can also be used to introduce concepts such as geometry and trigonometry, as well as to build problem-solving skills.

The total number of seats available can be calculated by adding the number of box and club seats available, which is

12,600 + 5400 = 18,000.

This total can then be multiplied by the respective percentages of the other two categories to get the total number of seats available.

For instance, the total number of bleacher seats available can be calculated by multiplying 12,000 by 18%.

12,000 x 0.18 = 2,160

Similarly, the total number of grandstand seats available can be calculated by multiplying 12,000 by 42%.

12,000 x 0.42 = 5,040

Hence, the total number of seats available for the baseball game is

18,000 + 2,160 + 5,040 = 25,200.

The correct statement is that the transfer of land by George to the corporation in exchange for stock should qualify for non-recognition of gain or loss under section 351 of the IRC, and each shareholder's basis in the stock received would depend on their respective contributions.

Fair market value is the amount that a product would sell for on the open market if all parties were acting in their own best interests, were not subject to excessive pressure, and were given a reasonable amount of time to complete the transaction (FMV).

The given scenario describes the formation of a corporation by Nancy and George, where Nancy contributes cash and George contributes land. The corporation issues shares of stock to Nancy and George in exchange for their respective contributions.

Section 351 of the Internal Revenue Code (IRC) provides rules for the non-recognition of gain or loss on the transfer of property to a corporation in exchange for its stock. To qualify for non-recognition, certain requirements must be met, including that the transfer must be made in exchange for stock, and the transferors must be in control of the corporation immediately after the exchange.

Assuming that the requirements of section 351 are met, the transfer of the land by George to the corporation in exchange for stock should not result in any immediate tax consequences. George's basis in the stock received would be equal to his basis in the land transferred. Nancy's contribution of cash would not affect her basis in the stock received.

Therefore, the correct statement is that the transfer of land by George to the corporation in exchange for stock should qualify for non-recognition of gain or loss under section 351 of the IRC, and each shareholder's basis in the stock received would depend on their respective contributions.

Marlo can draw two different isosceles right triangles and third vertices are (-0.5, 5) and (-0.5, 7)

An isosceles triangle is a type of triangle in which two sides of the triangle have the same length.

Since the triangle is isosceles, its third vertex must lie on the line that is perpendicular to the line passing through the two given vertices and passes through the midpoint of that line.

The midpoint of the two points (-3,6) and (2,6) connecting the line segment is

((-3+2)/2,    (6+6)/2) = (-0.5, 6)

The line passing through (-3,6) and (2,6) has equation y = 6. The line perpendicular to it passing through (-0.5,6) has equation x = -0.5.

Therefore, the third vertex of the isosceles right triangle must have coordinates (-0.5, y), where y is an integer.

To find how many different isosceles right triangles can be drawn, we need to find how many different integer values of y satisfy the condition that the distance between (-3, 6) and (-0.5, y) is the same as the distance between (2, 6) and (-0.5, y).

We know that the distance formula, So,

[tex]\sqrt{((2 - (-0.5))^2 + (6 - y)^2)}[/tex] = [tex]\sqrt{((-3 - (-0.5))^2 + (6 - y)^2)}[/tex]

Simplifying this equation gives:

(2.5)² = (3.5)²

y = 6 ± 1

Therefore, there are two possible values of y, 5 and 7, which correspond to the two possible third vertices of the isosceles right triangle: (-0.5, 5) and (-0.5, 7). So, Marlo can draw two different isosceles right triangles with two vertices at (-3, 6) and (2, 6) such that the coordinates of the third vertex are both integers.

Step-by-step explanation:

If the shapes are similar - then their lengths are proportional.

You can make a ratio and solve for the missing variable.

You must match the corresponding sides.

[tex]\frac{32}{48}[/tex] = [tex]\frac{d}{36}[/tex]

Cross mulitiply the "diagonal values" and divide by the value

diagonal from the variable.

32 × 36 = 48d

1152 = 48d

1152/48 = 48d/48

24 = d

Therefore, the scale factor of the smaller polygon to the larger polygon is 2. Therefore, the scale factor of the smaller triangle to the larger triangle is 6.

Scale factor refers to the ratio of any two corresponding lengths in two similar geometric figures. In other words, it is the ratio of the size of an object in one image or figure to the size of the same object in another image or figure, assuming that the two images or figures are proportional to each other. The scale factor can be used to determine the relationship between the sizes of the objects in the two figures or images.

Here,

1. The scale factor from the smaller polygon to the larger polygon is found by dividing the length of the larger polygon by the length of the smaller polygon:

scale factor = length of larger polygon / length of smaller polygon

scale factor = 14 / 7

= 2

2. The scale factor from the smaller triangle to the larger triangle is found by dividing the length of the larger triangle by the length of the smaller triangle:

scale factor = length of larger triangle / length of smaller triangle
