Answer: Answer is 3

BC        6

------ = ------

XY         3

Step-by-step explanation:

The statements below can be used to prove that the triangles are similar.

On a coordinate plane, right triangles A B C and X Y Z are shown. Y Z is 3 units long and B C is 6 units long.  

A B Over X Y = 4 Over 2

?  

A C Over X Z = 52 Over 13  

△ABC ~ △XYZ by the SSS similarity theorem.

Which mathematical statement is missing?

1.   Y Z Over B C = 6 Over 3  

2.  ∠B ≅ ∠Y

3.  B C Over Y Z = 6 Over 3  

4.  ∠B ≅ ∠Z

Answer:

  • StartFraction B A Over Y X = StartFraction B C Over Y Z EndFraction = StartFraction A C Over X Z EndFraction
  • StartFraction A C Over X Z EndFraction = StartFraction B A Over Y X EndFraction , Angle A is-congruent-to Angle X

Step-by-step explanation:

Given the way the triangles are named, corresponding sides are ...

  (BA, YX), (BC, YZ), (AC, XZ)

and corresponding angles are ...

  (A, X), (B, Y), (C, Z).

Similarity can be shown by having all three sides proportional (SSS), or by having any two angles congruent (AA), or by having two proportional sides and the angle between them (SAS).

__

The offered answer choices (in order) are ...

  • SSS similarity (one of the answers)
  • SSA similarity (not an option--except in a special case where more information is available)
  • SAS similarity (one of the answers)
  • non-corresponding sides proportional (nonsense)
  • non-corresponding sides and non-corresponding angles (nonsense)

Answer:

D. 48

Step-by-step explanation:

In the experiment, 16/40 landed exactly on heads. If you do 16/40 * 3/3 = 48/120.

This means that you can estimate 48 of the next 120 trials have 2 coins showing heads.

The area of a rectangle is 42 square feet.
Alchen [17]

Answer:

26 ft and 46 ft.

Step-by-step explanation:

The prime  factors of 42 are 2 * 3 * 7.

Possible lengths and widths  are:

L = 7, W = 6 giving a perimeter of  2*7 + 2*6 = 26 ft.

L = 14 , W = 3  giving perimeter = 34 ft.

L = 21, W = 2 giving perimeter = 46 ft.

Write a equation for the line parallel to
Llana [10]
Paralell has same slope
y=mx+b
m=slope
b=yint

same slope so other equation is
y=4x+b

input given point
(2,0)
x=2
y=0
0=4(2)+b
0=8+b
minus 8 both sides
-8=b

the equation is y=4x-8

Sheila has 11
RSB [31]

Answer:

6

Step-by-step explanation:

11 1/2 = 11.5

2 1/4 = 2.25

11.5 ÷ 2.25= 5.11

she needs 6 containers because you round up 5.11 to 6.

if your doing the work in fractions rather decimals let me know and I can explain it that way too
