Answer:
x+3y = 6
or, x = 6-3y.................(1)
3x+5y =6..........(2)
Substituting x = 6-3y in equation (2),
3 (6 - 3 y)+5 y =6
or, 18 - 9y +5y=6
or, y = 3
x = 6 - 3y = 6- 3.-3 = -3
Answer:
volume will be equal to 5,655 ft³
Step-by-step explanation:
diameter of swimming pool = 40 ft
depth increases from east-west lines is from 2 ft to 7 ft
so the average depth of the swimming pool can be calculated by

hence average depth comes out to be 4.5 m
volume of water in the pool will be equal to the volume of the pool
volume = 
= 
= 5,654.86 ft³
volume will be equal to 5,655 ft³ approximately
Answer:
6√2.
Step-by-step explanation:
The two radii are equal length and form a right angle, so the resulting triangle is 45-45-90. Therefore, the length of the chord (the hypotenuse of the triangle) is 6√2.
