Answer:
Each of the twin beds: 5 decorative pillows
Each of the queen beds: 11 decorative pillows
Step-by-step explanation:
Let the number of pillows used for each twin bed be x
Let the number of pillows used for each queen bed be y
she decorated 1 twin bed and 2 queen beds and used a total of 27 pillows. Thus;
x + 2y = 27 - - - (eq 1)
Also, she used
37 pillows to spruce up 3 twin beds and 2 queen beds. Thus;
3x + 2y = 37 - - - (eq 2)
From eq 1, x = 27 - 2y
Thus;
3(27 - 2y) + 2y = 37
81 - 6y + 2y = 37
81 - 4y = 37
4y = 81 - 37
4y = 44
y = 44/4
y = 11
x = 27 - 2(11)
x = 27 - 22
x = 5
Thus, she used 5 decorative pillows for each of the twin beds and 11 decorative pillows for each of the queen bed

Answer:
A =12.56 m^2
Step-by-step explanation:
Find the area of a circle with radius 4
A = pi r^2
A = 3.14 * 4^2
A =50.24
Since this is 1/4 of the circle, multiply by 1/4
A = 1/4 * 50.24
A =12.56 m^2
