Final answer:
To calculate the total cost of an online purchase, round the sales tax to the nearest penny and add it to the item's price. When combining multiple items, sum their prices and add the rounded sales tax to find the total cost.
Explanation:
When buying shoes or any item online and encountering a selling price that includes cents, you may need to perform rounding if further calculations are required. For example, to round $6.375 to the nearest penny, we would get $6.38 because the third digit after the decimal is 5 or more, thus we increase the second digit by one. From there, we would add the rounded sales tax to the original price of the item to find the total cost.
In a different scenario where you are adding two prices together, like $8.99 and $11.99, you get the subtotal of $20.98 before tax. Then calculate the sales tax by converting the percent to a decimal and multiplying by the subtotal, rounding again to the nearest cent if necessary. Finally, add the sales tax to the subtotal to get the total cost. For instance, if the sales tax was $1.47, adding this to the subtotal of $20.98 would give you a total of $22.45.

Answer:
y = 16
Step-by-step explanation:
The opposite angles of a parallelogram are congruent, hence
10y - 29 = 7y + 19 ( subtract 7y from both sides )
3y - 29 = 19 ( add 29 to both sides )
3y = 48 ( divide both sides by 3 )
y = 16

The function below has been transformed from f(x) = x2. Describe the transformation. h(x) = 4x2 + 12
Answer:
vertically expanded by a factor of 4then, translated upward 12 unitsStep-by-step explanation:
If f(x) = x² and g(x) = 4x² = 4f(x), the function g(x) represents a vertical expansion of f(x) by a factor of 4.
If h(x) = g(x) +12, the function h(x) represents a translation of g(x) by 12 units upward.
Together, these transformations on f(x) are ...
vertical expansion by a factor of 4translation upward by 12 units_____
Please be aware that there are alternate transformations that will do the same thing:
h(x) = 4(f(x) +3) . . . . is a translation upward by 3, then a vertical expansion by a factor of 4
h(x) = f(2x) +12 . . . . is horizontal compression of f(x) by a factor of 2, then a translation upward by 12.
David and Tonya each cut a cylinder in half. The cross-section that results from David's cut is a rectangle. The cross-section that results from Tonya's cut is a circle.
Answer:
Tonya cut the cylinder vertically and David cut it diagonally.
David’s cut along the length of his cylinder resulted in a rectangular cross-section, while Tonya’s perpendicular cut resulted in a circular cross-section. This illustrates principles of geometric cross-sections and plane intersections with solids.
Explanation:In the problem described, David and Tonya are each cutting a cylinder, a geometric shape. The cuts they make, and the cross-sections they create, depend on the orientation of their cuts in relation to the shape of the cylinder.
When David cuts the cylinder, his cross-section result is a rectangle. This implies that he made a longitudinal cut along the length of the cylinder, essentially splitting it from top to bottom.
When Tonya cuts her cylinder, the cross-section is a circle. This means she made a cross-sectional cut perpendicular to the length of the cylinder, slicing it into two equal half cylinders.
This problem illustrates the principles of geometric cross-sections and plane intersections with solids, which are part of the broader field of study in geometry.

Example: 72 divided by 9= 8 and 8 x 9 = 72
Hope this helps.
To get back the original number after dividing by 9, one should multiply the result by 9, because multiplication and division are inverse operations.
The student's question asks: James thought of a number and divided it by 9. What can he do to get back his original number? The correct answer is (A) multiply by 9. When a number is divided by 9 to undo this operation one must multiply it by 9. This is because multiplication is the inverse operation of division. Therefore, if James wants to obtain his original number back, he should take the result he got after dividing by 9 and multiply it by 9.
In the chinese symbol for yin and yang, the dash shows two semicircles formed by the curve seperating yin(dark) and yang(light). Is the circumference of the entire yin and yang symbol, less than, greater than, or equal to the perimeter of the yin?
The perimeter of the yin is bigger than the circumference of the full yin and yang symbol. This is due to the fact that the yin and yang symbol is made up of two semicircles which extend beyond the boundaries of the separate yin and yang halves.
What is Yin and yang Symbol?The Yin and Yang symbol is a Chinese symbol that represents complementary characteristics found in all things, such as light and dark, hot and cold, good and evil, and so on. A circle is divided into two sections, one black and one white, containing a smaller circle of the opposing color in each section.
Yin is represented by the black portion, which is connected with feminine traits, passivity, darkness, or coldness. Yang is represented by the white part, which is connected with masculine attributes such as activity, brightness, and warmth. The symbol is intended to reflect the harmony and balance of both of these opposing energies.
Therefore, the perimeter of the yin is bigger than the circumference of the full yin and yang symbol.

Final answer:
The circumference of the entire yin and yang symbol is greater than the perimeter of the yin semicircle, as the full symbol represents a complete circle while the semicircle includes only half the circumference plus its diameter.
Explanation:
The question about the Chinese symbol for yin and yang essentially asks about the relationship between the circumferences of two geometric shapes. If we consider the yin and yang symbol as a whole to be a circle, and the yang (or yin, since they are symmetrical) as a semicircle, then we can infer the following regarding circumferences and perimeters:
The circumference of a circle is 2πr, where r is the radius of the circle. The perimeter of a semicircle (half of the full circle and including the diameter) is πr + 2r. If we take the full yin and yang symbol to have a circumference of 2πr (since the full symbol is also circular), then the perimeter of the yang semicircle (which includes the straight edge boundary of the yin) would be less than the circumference of the full symbol, as it lacks the other semicircle's curved edge. In mathematical terms, πr + 2r is less than 2πr for any positive value of r.

Answer:
674.2 lb
Step-by-step explanation:
(5 ft)·(8 ft)·(1.2 in)·(12 in/ft)²·(2.54 cm/in)³·(2.7 g/cm³)/(453.592 g/lb) ≈ 674.2 lb

Comment on units conversion
Units conversion is easily done using conversion factors that have a value of 1. That is, the value of the numerator is equal to the value of the denominator. (12 in = 1 ft, for example). The numerator units are chosen to match units you want, while the denominator units are chosen to match units you want to cancel.
Here, we convert in³ to cm³ to lb using conversion factors given and ones we know.
In circle O, the measure of ∠ROW is 110°. What is the measure of arc RAW?
Answer:
250°
Step-by-step explanation:
We know that a circle has a total of 360°.
Now we know that ∠ROW is 110° and that Arc RAW has the same End points as ∠ROW.
We can safely assume that arc RAW will be the difference of ∠ROW and 360°.
So we then get:
360° - 110° = 250°
This means that Arc RAW will be 250°
Before she went on a diet, Jenna's waist measured 32.45 inches.After the diet, it measured 26.97 inches.How many inches did Jenna lose?
Answer:
5.48
Step-by-step explanation:
32.45 - 26.97 = 5.48
Answer:
Jenna lost 5,48
Step-by-step explanation:
Before the diet Jenna's waist measured 32.45 inches.
After the diet Jenna's waist measured 26.97 inches.
To get the difference between the two measures, we have to discount the new measure from the previous one.
So, difference is 26.97 inches-32.45 inches= -5,48. It is negative because she lost inches.
