The equations that could represent the quantities and constraints in this  situation are:

m = 12(15) ⇒ answer a

4n = c ⇒ answer c

b = 2(3) + 3(4.50) ⇒ answer e

Step-by-step explanation:

Jada plans to serve milk and healthy cookies for a book club meeting

  • She is preparing  12 ounces of milk and 4 cookies per person
  • There are 15 people in  the club
  • A package of cookies contains 24 cookies and costs $4.50
  • A 1-gallon jug of  milk contains 128 ounces and costs $3

n represents number of people in the club,  

m represents the ounces of milk

c represents the number of cookies

b represents Jada's budget in dollars

∵ m represents the ounces of milk

∵ She is preparing  12 ounces of milk

∵ There are 15 person in the club

∴ m = 12(15)

∵ She is preparing 4 cookies per person

∵ c represents the number of cookies

∵ n represents the number of people in the club

∴ 4n = c

∵ A package of cookies contains 24 cookies

∵ She needs = 15 × 4 = 60 cookies

∵ 60 ÷ 24 = 2.5

∴ She needs to buy 3 packages of cookies

∵ She needs = 15 × 12 = 180 ounces of milk

∵ A 1-gallon jug of  milk contains 128 ounces

∵ 180 ÷ 128 = 1.406

∴ She needs to buy 2 A 1-gallon jug of milk

∵ The cost of each jug of milk is $3

∵ The cost of each package of cookies is $4.50

∵ b represents Jada's budget in dollars

∴ b = 2(3) + 3(4.50)

The equations that could represent the quantities and constraints in this  situation are:

m = 12(15) ⇒ answer a

4n = c ⇒ answer c

b = 2(3) + 3(4.50) ⇒ answer e

Which is the next step in the following construction of a regular hexagon?
laila [671]

Answer:

With compass setting the same as line segment PA, place the compass

at C and draw an arc that intersects the circle ⇒ answer D

Step-by-step explanation:

<em>Lets revise the step of construction a regular hexagon</em>

1. Draw circle with center P; put point A on the circle's edge at

any place

2. With compass setting the same as line segment PA, place the

compass at A and draw an arc that intersects the circle at B

3. With compass setting the same as line segment PA, place the

compass at B and draw an arc that intersects the circle at C

4. <em>With compass setting the same as line segment PA, place the</em>

<em>compass at C and draw an arc that intersects the circle</em> at D

5. Contain with the same step of placing the compass at the previous arc and draw an arc with same distance of PA until you reach point A again, then join each arc on the circle forming the regular hexagon

The given steps are:

Circle with center P; point A is along the circles edge, an arc at point B

is along the circles edge, and an arc at point C is along the circles edge

According to the steps above, the next step is:

<em>With compass setting the same as line segment PA, place the </em>

<em>compass at C and draw an arc that intersects the circle</em> (step 4)
