Answer:

The answer is 3 inch

Step-by-step explanation:

To start off, the equation you want to use the formula V=whl

Next, you simply plug in the values you already know, so you have 450=w*20*7.5

After you do that you multiply 20 times 7.5 to get which is 150, which leaves you with 450= w *150 to solve for w, you need to isolate it. To do that you divide 450 by 150. You are left with the answer of 3.

If C=(a,b,x,y) and D=(m,n,o,p) then c union d is
Ilya [14]

Step-by-step explanation:

here,

C={ a,b,x,y}

D ={ m,n,o,p}

now,

C union D ={a,b,x,y} union {m,n,o,p}

= {a,b,x,y,m,n,o,p}

therefore C union D ={ a,b,x,y,m,n,o,p}

I don't get this problem from maths.
NeTakaya

Answer:

100/3 or 33.33

Step-by-step explanation: If the perimeter of the whole figure is 220, we can use that number to solve the equations on the trapezoid.

2(2x-3) + 2(4) + 2(4x+1)

4x - 6 + 8 + 8x + 2

12x + 2

Now we have to set the equation equal to the perimeter to find the value of x

12x + 2 = 220

12x = 218

x = 109/6

Since we are only finding the length of PS, we will plug x into its equation (2x - 3).

2(109/6) - 3

109/3 - 3

109/3 - 9/3

100/3
