Answer:

9 cookies per dollar

so we divide top and bottom by 4

36 cookies ÷ 4

4 dollars ÷ 4

=  

9 cookies

1 dollar

=  

9 cookies

-----------------

dollar

= 9 cookies per dollar

Twice as many students are in the chess club as in the fencing club.The number of students in the fencing club is one fifth the
jekas [21]

Answer:

28 students

Step-by-step explanation:

Let number of students in cooking club = x

Number of students in fencing club = 1/5 x

Number of students in chess club = 2(1/5)x

Since, There are 42 more students in the cooking club than in the chess club

Then ;

Number of students in chess club = Number of students in cooking club - 42

2(1/5)x = x - 42

(2/5)x - x = - 42

(2/5)x - x = - 42

-0.6x = - 42

x = 42 / 0.6

x = 70

Hence, number of students in chess club :

(2/5) * 70 = 28

Find the perimeter of a rhombus the length of whose diagonals are 10 cm and 24 m.

now, the sides in a rhombus are all equal, thus the perimeter is 13+13+13+13.
