First take the inside diameter and divide by 2 to get the radius (4cm)
Then use
r^2 with 'r' being your radius to get the area of the base
The area is 12.7 cm
Now multiply the height by the area of the base to get the volume/ capacity!
40cm x 12.7cm (rounded to the nearest tenth) = 502.7 cubic centimeters
Answer:
The given system as (3,3) as its solution.
Step-by-step explanation:
Here, the given system of the equation is:
4 x + 2 y = 18
................ (1)
2 x + 3 y = 15 ............... (2)
Now, to use the elimination method, w need to eliminate any of the variable.
Eliminate the variable x in the given system.
Multiply equation (2) with -2 we get,
(2 x + 3 y = 15 )(-2) ⇒ -4x - 6y = -30 ....... (3)
Add (1) and (3), we get:
4 x + 2 y -4x - 6y = 18 -30
or, - 4 y = - 12
or, y = 12/4 = 3 ⇒ y = 3
Putting in (1), we get
4x + 2(3) = 18 or, 4x = 18 - 6 = 12
or, x = 3
(x,y) = (3,3)
Hence, the above system as (3,3) as its solution.

dk man
Step-by-step explanation:
Answer:
solve for x
x=2
Step-by-step explanation:
x2-20x-17=-53
reorder like terms x2= 2x 2x=20x-17=-53
collect like terms 2x-20x=-18x -18x-17=-53
move constant to the right hand side and change its sign -18x=-53+17
calculate the sum -53+17= -36 -18x=-36
divide both sides by -18 -18x÷-18= x -36÷-18=2
x=2
