Answer:

  1. x+y≤80; x≥8; y≥5
  2. see attached for a graph
  3. Twenty campers are doing water-based activities and 40 campers are doing ground-based activities.

Step-by-step explanation:

1. Let x and y represent the numbers of campers doing water- and ground-based activities, respectively.

  x + y ≤ 80 . . . . . . a maximum of 80 campers can be accommodated

  x ≥ 8 . . . . . . . . . . a minimum of 8 campers should be water-based

  y ≥ 5 . . . . . . . . . . a minimum of 5 campers should be ground-based

__

MZJ and m M are base angles of isosceles trapezoid JKLM. If mZJ = 18x + 8 and m_M=11x + 15 find m2K.
maxonik [38]

The question is incomplete. Here is the complete question.

m∠J and m∠Kare base angles of an isosceles trapezoid JKLM.

If m∠J = 18x + 8, and m∠M = 11x + 15 , find m∠K.

A. 1

B. 154

C. 77

D. 26

Answer: B. m∠K = 154

Step-by-step explanation: <u>Isosceles</u> <u>trapezoid</u> is a parallelogram with two parallel sides, called Base, and two non-parallel sides that have the same measure.

Related to internal angles, angles of the base are equal and opposite angles are supplementary.

In trapezoid JKLM, m∠J and m∠M are base angles, so they are equal:

18x + 8 = 11x + 15

7x = 7

x = 1

Now, m∠K is opposite so, they are supplementary, which means their sum results in 180°:

m∠J = 18(1) + 8

m∠J = 26

m∠K + m∠J = 180

m∠K + 26 = 180

m∠K = 154

The angle m∠K is 154°
