A rental hall has 60 tables.
55% of the tables have 10 chairs at each table.
The remaining 45% of the tables have 8 chairs at each table.

Complete the model.
Then complete the statements to find the total number of chairs in the rental hall.

Answer 1

Answer:

Plz name me brainlieset thank you

Step-by-step explanation:

55% of the tables would be 33 tables times 10 chairs equals 330 Chairs That mean 60 Tables -33 tables Leaves you with 27 tables Times 8 Chairs Equals 216 Chairs So 330 and 216Equals 546 chairs

Answer 2

Answer:

55% 10 chairs:33

45% 8 chairs:27

330

216

546

Answer:

  see attached

Step-by-step explanation:

The missing measures can be found by making use of the properties of tangents, special triangles, trig functions, and circles.

Radii

All of the incircle radii are the same length:

  CJ = CK = CL = 4

Angles

All of the segments to the incenter from the triangle vertices are angle bisectors. Of course, the sum of angles in a triangle is 180°, and the acute angles in a right triangle are complementary.

  ∠CML = ∠CMJ = 20°

  ∠CPL = ∠CPK = 40° . . . . . (∠P = 180° -40° -60° = 80°)

  ∠CNJ = ∠CNK = 30°

The central angles are complementary:

  ∠MCL = ∠MCJ = 70°

  ∠PCK = ∠PCL = 50°

  ∠NCJ = ∠NCK = 60°

Tangents

The two tangents from a vertex are congruent. Each will be the radius divided by the tangent of the (half) vertex angle.

  ML = MJ = 4/tan(20°) = 11.0

  PL = PK = 4/tan(40°) = 4.8

  NJ = NK = 4/tan(30°) = 6.9

Angle bisectors

The length from each vertex to the incenter will be the radius divided by the sine of the (half) vertex angle.

  MC = 4/sin(20°) = 11.7

  PC = 4/sin(40°) = 6.2

  NC = 4/sin(30°) = 8.0

__

Additional comment

The given dimensions are slightly off. The angle at M is 19.9831°, or the length LM is 10.9899 units, or the radius is 4.00367. In order to keep the numbers nearly consistent, we have rounded to one decimal place. The 30° triangle is the only one with an angle that has a rational trig function (sine).

Answers

Answer:

your answer is -19.1

Step-by-step explanation:

you add -3.6 and -15.5 to get -19.1

to determine that 15.5 is negative look at key words surrounding it, like decreased, that tells you that your number is a negative.

in a triple batch of spice mix, there are 15 teaspoons of salt and 6 teaspoons of garlic powder. how much salt is used with 8 teaspoons of garlic powder?

Answers

20 teaspoons

Per batch amounts:
Salt = 15/3 = 5 teaspoons
garlic powder = 6/3 = 2 teaspoons

8 teaspoons of garlic powder number of batches:

8/2 = 4 batches

4 batches of salt

4 * 5 = 20 teaspoons

Answer:

2 teaspoons

Divide 15 by 5:

15/5 = 3

Divide 6 by 3:

6/3 = 2

Thus, there are 2 teaspoons of garlic powder used :)
