I do not know which formula to useCarla bought a dress at a sale for 20% off the original price. The sale price of the dress was $68.90. Find the original price of the drees, in dollars.

Step by step explanation please.

Answer 1

Answer:

Answer:

I think it's the second formula.

Step-by-step explanation:

Let x be the original price.

The discount rate is 20%

Sale Price is $68.90

Discount = 20% of x = 0.2x

Using the formula, Sale Price = Original Price - Discount,

Original Price - Discount is x-0.2x = 0.8x

$68.90 = 0.8x

From here on, just do the equation :) Hope this helps!

Answer 2

Answer: Use the 3rd one because it has fewer steps and will give you the answer

c. 5/sin(25°)
d. sin(25°)/5

Answers

Answer:

b. 5tan(25°)

Step-by-step explanation:

The tangent function gives the ratio between the side opposite and the side adjacent to the angle. That is ...

tan(25°) = ?/5

Multiplying by 5 solves the equation:

? = 5·tan(25°)

Any shape can be used as the profile for a detail view just as long as it is a ______________ contour.

Answers

Final Answer:

Any shape can be used as the profile for a detail view just as long as it is a closed contour.

Explanation:

A detail view is a common technique in engineering and technical drawing used to magnify a specific portion of a complex object for a more detailed examination. The profile of this magnified portion, often referred to as the "cutting plane" or "profile," can indeed take on various shapes. However, it is crucial that this shape forms a closed contour.

A closed contour is a shape with no open ends or gaps, which means that it is a continuous and uninterrupted boundary. This is essential because a closed contour ensures that the detail view accurately represents the specific area of interest without missing any critical details. If the contour were not closed, it would lead to an inaccurate portrayal of the object and could result in misunderstandings or errors during the manufacturing or construction process.

In technical drawing and engineering, precision is paramount, and using a closed contour for the profile of a detail view guarantees that the depiction is accurate and complete. It allows engineers, architects, and manufacturers to focus on specific areas while maintaining the integrity of the overall design.

Any shape can be used as the profile for a detail view just as long as it is a closed contour. A closed contour means that the shape forms a closed loop with no openings or gaps. This is important for creating accurate and meaningful detail views in technical drawings and diagrams.

to multiply a number by 12, Carter likes to multiply the number by 10 and then multiply it by 2 and add the product. Write an expression with parenthesis how carter would solve 12×16

Answers

Since carter multiplies by 10 and then by 2 and adds the two, here we have been given 16 * 12

Step 1: Carter would first multiply the number by 10. This would be = 16*10

Step 2: Carter would multiply the number by 2. This would be = 16*2

Step 3: He would add the two. This would be = (16*10) + (16*2)

Carter's solution would be:

=16*12

=(16*10) + (16*2)

= 160 + 32

= 192
