Step-by-step explanation:

okay so my explanation is if they both are selling for the same price then look at how many they are selling if store 1 is selling 12 for 3.50 and Store 2 is selling 15 then Store 2 has the better price.

Colin is painting figurines. He spends 20 minutes painting each figurine. After painting for 60 minutes, he still has 9 more figurines left to paint.
The number f of figurines left to paint is a function of t, the amount of time in minutes Colin spends painting.
f=________

Answers

Answer: f=180, because you multiply 9 and 20 to find out how many minutes it takes

F=180 I think is the correct answer

Which angle has the same measurement as angle DEA, and how do you know that the measurement is the same?

Answers

Answer:

I don't know the exact answer but the correct answer would be A(Then, unknown value)E I think.

Step-by-step explanation:

The reason why is because it would make a square if you put the answer and ADE together.

THIS COULD BE WRONG
The answer would beDEA or AED, they are both the same. If you extend the two lines like I did, you can tell they are parallel. Angle C and angle A on ADE are congruent because they are corresponding, right angles are equal, so you are left with E and A on triangle ABC.

A sequence of transformations is applied to triangle CDE to create triangle C'D'E'.

Select all the sequences of transformations that could be applied to triangle CDE so that triangle CDE is congruent to triangle C'D'E'.

D.a translation 5 units down and then a dilation by a scale factor of 2


E.a translation 5 units down and then clockwise rotation of 90 degrees.


F.a reflection across y-axis and then translation 5 units down

Answers

Answer:

A, C, and E

Step-by-step explanation:

for a shape to be congruent it must be the same size and shape so

A would be correct because it only changes the position of the shape.B would be incorrect for it is dilated which changes its shape.C is correct because it also only changes the position.D is incorrect because it dilates the shape which changes the size.E would be the last correct answer because it keeps the size and shape and only changes the position.

Thus your answer is A, C, and E

To measure the distance across a pond, a surveyor locates points A, B, C, D, and E as shown. Find the length of AB to the nearest meter. Explain how you got this answer.

Answers

Answer:

formula with a squared term.

It’s not about distance in the sense of walking diagonally across a room. It’s about any distance, like the “distance” between our movie preferences or colors.

If it can be measured, it can be compared with the Pythagorean Theorem. Let’s see why.

Understanding The Theorem

We agree the theorem works. In any right triangle:

pythagorean theorem

If a=3 and b=4, then c=5. Easy, right?

Well, a key observation is that a and b are at right angles (notice the little red box). Movement in one direction has no impact on the other.

It’s a bit like North/South vs. East/West. Moving North does not change your East/West direction, and vice-versa — the directions are independent (the geek term is orthogonal).

The Pythagorean Theorem lets you use find the shortest path distance between orthogonal directions. So it’s not really about right triangles — it’s about comparing “things” moving at right angles.

You: If I walk 3 blocks East and 4 blocks North, how far am I from my starting point?

Me: 5 blocks, as the crow flies. Be sure to bring adequate provisions for your journey.

You: Uh, ok.

So what is “c”?

Well, we could think of c as just a number, but that keeps us in boring triangle-land. I like to think of c as a combination of a and b.

But it’s not a simple combination like addition — after all, c doesn’t equal a + b. It’s more a combination of components — the Pythagorean theorem lets us combine orthogonal components in a manner similar to addition. And there’s the magic.

In our example, C is 5 blocks of “distance”. But it’s more than that: it contains a combination of 3 blocks East and 4 blocks North. Moving along C means you go East and North at the same time. Neat way to think about it, eh?

From the picture attached,

AB and ED are the parallel sides of two triangles ΔCDE and ΔCBA.Measure of sides

        DE = 5 m, CD = 5 m, CE = 4 m and CA = 12 m

In ΔCDE and ΔCBA,

Two sides AB and ED are parallel and two lines AC and BC are intersecting these lines,

Therefore, ∠CDE ≅ ∠CBA and ∠CED ≅ ∠CAB [Corresponding angles]

By AA postulate of similarity,

ΔCDE ~ ΔCBA.

By using the property of two similar triangles,

   "Corresponding sides of two similar triangles are proportional"

[tex]\frac{CE}{CA}= \frac{DE}{BA}[/tex]

[tex]\frac{4}{12}= \frac{5}{AB}[/tex]

[tex]AB=\frac{5\times 12}{4}[/tex]

[tex]AB=15[/tex] m

      Therefore, length of AB will be 15 meters.
