Answer:

Step-by-step explanation:

x(6.75) + (5 - x)(5.50) = 5(6.25)

6.75x + 27.5 - 5.50x = 31.25

                         1.25x = 3.75

                                x = 3 lb of seed A

I’m confused on the type of angles these are and how to solve them . (Parallel lines and Transversals)
svp [43]

Answer:

7) 49°

8) 77°

9) 87°

10) 135°

Step-by-step explanation:

7) The angles are between the parallel lines, so are "interior." They are on opposite sides of the transversal, so are "opposite interior" angles. Such angles are congruent, so ...

... ? ≅ 49°

8) The angles are adjacent interior angles, so are supplementary.

... ? + 103° = 180°

... ? = 77°

9) The angles are outside the parallel lines, so are "exterior." They are on opposite sides of the transversal, so are "opposite exterior" angles. Such angles are congruent.

... ? ≅ 87°

10) These are vertical angles, so are congruent. (The other parallel line is irrelevant and doesn't need to be there for this relationship to be true.)

... ? ≅ 135°

Jay is copying an angle. His work so far is shown below. Explain the importance of his next step, which is placing the point of
FinnZ [79.3K]

Answer:

  your answer is correct.

Step-by-step explanation:

For the purpose here, we'll call the missing point on the arc through Z point X.

Essentially, you want to make ΔXYZ ≅ ΔLMN by SSS. The construction so far ensures LM ≅ MN ≅ XY ≅ YZ. By copying the length LN to XZ, you ensure the congruence of the remaining sides of the triangles.

Then ∠XYZ ≅ ∠LMN because corresponding parts of congruent triangles are congruent.

In short, XZ needs to be the same distance as LN.

Which segment of the triangle will give you the height of your peak? Write the equation for the proportion that will allow you t
Novosadov [1.4K]
The segment that will give the height of the peak is the segment that is located from the right angle to the peak.
 To find the height, we can use the fact that we have two similar triangles.
 We are going to define a variable.
 We have:
 x: height of the peak.
 For similar triangles, we have the following relationship:
 \frac{x}{20} = \frac{6}{3}
 From here, we clear the height of the peak
 Answer:
 
the equation for the proportion that will allow you to find the height of your peak is:
 
\frac{x}{20} = \frac{6}{3}
