C.3/15=x/12
D.12/15=x/3

Answers

Answer:

A 3/30=x/12

Step-by-step explanation:

According to the recipe,

For 2 batches, 3 cups of flour required.

One batch has 15 mix rolls

Then 2 batches will have 2 (15) = 30 rolls

What is the area of the following circle?
Either enter an exact answer in terms of 7 or use 3.14 for it and enter your answer as a decimal.
d=2

Answers

π square units.

The formula for the area of a circle is , where the radius is represented by r. Also, the radius is half of the diameter.

Since half of the diameter is 1 unit, that is the radius, making our formula , or . The identity property of multiplication shows that multiplying by 1 doesn’t affect the result, so we can remove the multiplication by one. This leaves us with just pi, so the answer is π square units.

A cube has a surface area of 96 square centimeters. How long is each face of the cube?

Answers

Answer:

I believe the answer would be 4

Step-by-step explanation:

I'm going to use (a) to represent the side length in my explanation. side length is equivalent to the square root of the surface area over 6. The 6 is coming from there being 6 faces on a cube. So to solve this equation, you would first write it out.  a=96/6. Next you would divide 96/6, giving you 16. and then lastly, you would find the square root of 16, which is 4. giving you a final answer of 4.

Hope this helps, and you understand it more!

what do you call a crushed angle ?

Answers

Answer:

A Rectangle

Step-by-step explanation:

a wrecked angle

A crushed angle is commonly referred to as a "rectangle" or a "wrecked angle".

When an angle is crushed or collapsed, its sides are no longer straight or evenly spaced, and its vertex may be shifted or deformed.

This deformation can occur in various contexts, such as in physical objects or in mathematical diagrams. The angle's original shape has been significantly changed due to external influences.

Thus, a crushed angle is commonly referred to as a "rectangle" or a "wrecked angle".

This is a play on words, as a rectangle is a shape with four right angles, and when an angle is crushed or wrecked, it can resemble a rectangle.

A waterpark sold 72 child tickets and 24 adult tickets. What percentage of the tickets sold one child tickets

Answers

Answer:

1.042% of the total tickets sold 1 child ticket.

Step-by-step explanation:

As given,

A Water park sold 72 child tickets and 24 adult tickets.

So,

The total number of ticket sold by a Water park = Total child ticket sold + Total adult ticket sold

⇒The total number of ticket sold by a Water park = 72 + 24 = 96

Now,

The total child ticket sold = [tex]\frac{72}{96}[/tex]×100% = 0.75×100% = 75%

Now, we get

72 child ticket sold % = 75

⇒ 1 child ticket sold % = [tex]\frac{75}{72}[/tex] = 1.042%

So, we get

1.042% of the total tickets sold 1 child ticket.

Geometry
Is Dn (triangle DEF) = triangle D'E'F' an enlargement or a reduction? What is the scale factor n of the dilation?

Answers

Answer:

A. Enlargement, 1.5

Step-by-step explanation:

Comparing the two triangles, it would be observed that ΔD'E'F' is larger than ΔDEF. This implies that ΔDEF has been multiplied by a scale factor.

To determine the scale factor used, consider the side DE and D'E' of the two triangles:

scale factor = [tex]\frac{D'E'}{DE}[/tex]

                   = [tex]\frac{6}{4}[/tex]

scale factor  = 1.5

Therefore, ΔDEF was enlarged to ΔD'E'F' using a scale factor of 1.5. Then the correct option is A.
