nadezda [96]4 years ago
5 0

Answer:

CDG = 100°

Step-by-step explanation:

CDG = BEF

BEF + ADC = 180°

5x° + 4x° = 180°

9x° = 180°

x = 180°/9

x = 20°

CDG = 5x°

CDG = 5(20°)

CDG = 100°

Three freshmen, five sophomores, and four juniors are on the school's chess team. the coach must select three students to attend
Solnce55 [7]
The first expression, 12C3, is the right answer. There is no limitation saying that the team must be made up of one student from each year level. Furthermore, no distinction has been made among the three players (no assignments of Boards 1, 2, or 3), as the question just asks how many different groups. Since order does not matter, this is a combination. (If order mattered, this would be a permutation).

A math book comprises of two sections: arithmetic and geometry in the ratio 5:3. How much of each type of content will be needed
Sophie [7]

Answer:

Arithmetic content = 300 pages

Geometric content = 180 pages

Step-by-step explanation:

Arithmetic : Geometry = 5 : 3

Total pages of book = 480

How much of each type of content will be needed to make a book of 480 pages?

Total ratio = arithmetic + geometric

= 5 + 3

= 8

Arithmetic content = 5 / 8 × 480

= 0.625 × 480

= 300

Arithmetic content = 300 pages

Geometric content = 3 / 8 × 480

= 0.375 × 480

= 180

Geometric content = 180 pages
