Answer:

2.8kg

Step-by-step explanation:

There are 7 parts of meat for every 3 parts so there are 7+3=10 parts in total.

4/10=1 "part"

there are 7 parts of meat so (4/10)*7=28/10=2.8kg of meat.

explain how arc length and the measure of the central angle of a circle are related. check my answer?
vovikov84 [41]
The central angle and the length of arc are related by the formula:

Length of arc = (θ/360) * 2πr

Where θ = Central angle.

If the central angle is one quarter of the entire circle, the length of arc would also be one quarter of the entire circumference of the circle.

Only the triangles in figures <u>5 are congruent</u>

<h3>Further explanation </h3>

Triangles are said to be congruent if:

  • 1. all three sides equal (SSS ---> side, side, side)
  • 2. two sides and the included angle of 2 triangles, are equal (SAS -> Side, Angle, Side)
  • 3. If the two angles and the included sides of the 2 triangles are equal (ASA -> Angle, Side, Angle)
  • 4. If the two angles and the non-included sides of 2 triangles are equal (AAS -> Angle, Angle, Side)

1. △ABC ≠ △DCE : not congruent

at least 3 parts (sides or angles) are compared, in the picture only 2 sides are compared

2. △ABC ≠ △XYZ : not congruent

the angles not includes between two sides

3. △RST ≠ △VUT : not congruent

a minimum of 3 parts (sides or angles) are compared, in the picture only 1 angle and 1 side are compared

4. △DEF ≠ △DHG :  not congruent

at least 3 parts (sides or angles) are compared, in the picture only 2 sides are compared

5. △JKL ≅ △KJM : congruent with ASA theorem
