# Which strategies can be used to solve this problem? rosa organized a game day at her house. she plans to have 2 groups of 5 people play charades, and 3 groups of 4 people play board games. what is the greatest number of people who could be at rosa's game day? choose all answers that are correct. a. draw a diagram. draw 2 squares and 5 circles. then draw 3 squares and 4 circles. add the total number of squares and circles. b. use logical reasoning. think that finding 2 groups of 5 is the same as 2 × 5 = 10 and that 3 groups of 4 is the same as 3 × 4 = 12. then add 10 + 12. c. model the problem. show 2 groups of 5 chips and 3 groups of 4 chips. then count all the chips. d. translate into an equation. 2 × 3 × 4 × 5 = n

You have a lot of work here for just one question, I will start by helping you with the first 2.

For #1, the major arc is 310, so the minor arc is only 50. The central able of ROQ is equal to the measure of it's arc. So it is 50.

For #2, when you have 2 chords the products of the divided segments on each cord are equal. So we can write and solve the equation below.

4x = 3.5(6)
4x = 21
x = 5.25
The sector of a circle is drawn by drawing two radii intercepting an arc. The area of the sector is calculated by calculating first the area of the whole circle. Then, this value is multiplied by the ratio the measure of the intercepted arc to one whole revolution. The answer to this item is the THIRD OPTION.
The second choice is correct.

The angle of the sector is one fraction of 360°.  Therefore the sector is a fraction of the entire circle.  Multiply this fraction by the area of the entire circle and you get the area of the sector.
It is B and C. The answer is B and C or B and D
I think it's D but not sure
Hello There!

The value for the angles is not provided.
Therefore, i'd say the answer is congruent.

Hope This Helps You!
Good Luck :)

B and C are both correct.

Congruent (APEX)

Congruent

Step-by-step explanation:

B.Use logical reasoning. Think that finding 2 groups of 5 is the same as 2 × 5 = 10 and that 3 groups of 4 is the same as 3 × 4 = 12. Then add 10 + 12.
