You've won a new prize! An event planner is reserving rooms for a company-wide event. Each ballroom can hold 90
people and each conference room can hold 17 people, and together they must hold at least
the 1,930 people participating.
Select the inequality in standard form that describes this situation. Use the given numbers
and the following variables.
x = the number of ballrooms
y = the number of conference rooms
17x + 90y = 1,930
90x + 17y > 1,930
90x + 17y 5 1,930
17x + 90y > 1,930

hi im bob : l

step-by-step explanation:

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3

your answer would be b
