So first you have to multiply 21 by .1 to figure out ten percent 
you then get 2.1 
you add 21 and 2.1 together and get 23.1
then since you have 3 people you divide by 3 and get 7.7
therefor 7.7 is your answer

AH the second question
Degger [83]

Answer:

ii. 55 degrees.

Step-by-step explanation:

(ii)

Consider the  quadrilateral ABCD.

Angle n = 180 - 96 = 84 degrees  ( opposite angles of a cyclic quadrilateral are supplementary).

Consider triangle ABC: the 3 angles are supplementary, so

m < j = 180 - 84 - 41

=  55 degrees.

the sum of the measures of the interior angels of a convex polygon is 3240 classify the polygon by the number of sides
Ipatiy [6.2K]

Answer:

20-gon

Step-by-step explanation:

First we start with the formula  to find what the sum of angles will be if we know the number of sides.  


S=(n-2)*180 where S is the sum of angles and n is the number of sides.


Normally you'd plug in n to find S, but you can do the opposite too.


3240=(n-2)*180


Let me know if you need help working it from here.

A type of green paint is made by mixing 2 cups of yellow with 3.5 cups of blue.
aliya0001 [1]

Answer: Use 1.75 cups of blue and 1 cup of yellow

Step-by-step explanation:

The given problem can be placed in the category of ratios and proportions. There is a ratio of color mixing which contains the proportion of two colors i.e blue and yellow. When we use 2 cups of yellow with 3.5 cups of yellow then we get green color so if we mix half of their amounts then we can get less or simply half amount of color too. Hence adding 1 cup of yellow and 1.75 cup of blue will give us small amount in result.
