Answer:
x = 4 , y = ⅕
Step-by-step explanation:
2x + 5y = 9 (1)
3x - 5y = 11 (2)
Add (1) and (2)
5x = 20
x = 4
Using (1), find y
2(4) + 5y = 9
5y = 1
y = ⅕
Answer:
193
Step-by-step explanation:
9^2 = 81+181=262-69= 193
The total fabric Morgan needs to cover the cushions will be 19.64 square feet.
It is given that each cushion has a circumference of 7.85 feet.
It is known that the circumference of a circle = 2πr, where 'r' is the radius of the circle.
2πr = 7.85
r = 1.25
<h3>What is an area of a circle?</h3>
area of a circle is πr².
now, we can calculate the area = π× 1.25² = 4.91 square feet
since each circular cushion has two circular faces so the total number of faces Morgan needs to cover will be 4.
Therefore, the total fabric needed= 4×4.91 = 19.64 square feet.
