To find out if (2, 2) is a solution, substitute/plug the point into the inequality:

y ≤ 4x - 6    

2 ≤ 4(2) - 6

2 ≤ 8 - 6

2 ≤ 2    

2 is equal to 2, so (2, 2) is a solution for this inequality

Answer:

yes

Step-by-step explanation:

fill in x and y   y \leq  4x - 6

                        2 \leq  4(2) - 6

then simplify 2 \leq 8-6

                     2 \leq 2

this is true because 2 is less than or equal to 2

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 18 feet a
Radda [10]

Answer:

5.2%

Step-by-step explanation:

Volume of cylinder= πr²h

In Container A,

D= 18ft, r=18/2=9ft, h=15ft

volume= 22/7 × 9² × 15

= 26730/7 cubic ft.

In Container B,

D=16ft, r= 16/2=8ft, h=18ft

volume= 22/7 × 8² × 18

= 25344/7 cubic ft.

percent of amount of water left in Container A= percent of container A that is full after pumping

Amount of water left in Container A,

26730/7 - 25344/7 = 1386/7

Therefore, % of container A that is full= 1386/7 ÷ 26730/7 × 100

(1386×7×100)/(7×26730)= 5.185

To the nearest tenth= 5.2%
