Answer:

  • C. Change the length to side CB to 8 feet

Step-by-step explanation:

<u>Corresponding sides of similar triangles should have same ratio:</u>

  • PR/AC = PQ/AB = RQ/CB
  • 7.5/6 = 5/4 = 10/CB
  • 10/CB = 1.25
  • CB = 10/1.25
  • CB = 8 feet

Correct choice is C

Which results from a cross section made perpendicular to the base of a square pyramid? Check all that apply.
Mamont248 [21]

<span>ú   </span>The square-shaped slice can be made from a slice parallel to the base of a right rectangular prism, cube, and right rectangular pyramid with a square base.  The triangle-shaped slice and isosceles trapezoid-shaped slice can be made with a slice made perpendicular to the base of a right rectangular pyramid.  A pentagon-shaped slice cannot be made from a slice made parallel or perpendicular to the base of either a right rectangular prism, right rectangular pyramid, or cube.

45 minus 4.5. Show work
Dmitrij [34]
Let's do subtraction by first starting with the ones place and then the tenths place of the subtrahend.
45-4=41; 44, 43, 42, 41
41-.5= 40.5; 40.9, 40.8, 40.7, 40.6, 40.5
45-4.5=40.5
We can check by using addition.
40.5+4.5=
44+1=
45

If ΔEFG ~ ΔLMN with a ratio of 2:1, which of the following is true?
strojnjashka [21]

Answer:

  segment EF over segment LM equals segment FG over segment MN

Step-by-step explanation:

The triangles are similar, not congruent, so any answer choice with the word "congruent" can be ignored.

The sequence of letters in the triangle name tells you the corresponding segments:

  • EF corresponds to LM
  • EG corresponds to LN
  • FG corresponds to MN

Corresponding segments have the same ratio, so ...

  EF/LM = FG/MN . . . . . . matches the first answer choice

  EF/LM = EG/LN . . . . does not match the 3rd answer choice
