Answers:

  • Just corn = 10 acres
  • Just wheat = 7 acres
  • Intersection of corn and wheat = 4 acres
  • Union of corn and wheat = 21 acres

===========================================

Explanation:

The number 10 inside circle A, but outside circle B, represents the number of acres dedicated to corn only (no wheat).

The number 7 inside circle B, but outside circle A, represents the number of acres dedicated to wheat only (no corn)

The number 4 in the overlapping region of both circles represents the number of acres for both corn and wheat at the same time.

The union of two sets is simply combining the two sets together to form one bigger set. If an element is in A union B, then it is either in A or B, or both. We add the values in the circles to get 10+7+4 = 17+4 = 21 to represent 21 acres for corn only, for wheat only, or for both.

Note: There are no values outside the circles, so none of the land is for any other purpose other than corn or wheat.

Anna [14]

Answer:

x = 65 , y = 64

Step-by-step explanation:

y - 16 and 2y + 4 are same- side interior angles and sum to 180° , that is

y - 16 + 2y + 4 = 180

3y - 12 = 180 ( add 12 to both sides )

3y = 192 ( divide both sides by 3 )

y = 64

then

2y + 4 = 2(64) + 4 = 128 + 4 = 132

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

2y + 4 is an exterior angle of the triangle , then

x + 67 = 132 ( subtract 67 from both sides )

x = 65
