a rectangular fish tank 60 centimeters by 15 centimeters by 34 centimeters is 1/3 full of water. find the volume of water needed

son4ous [18]

Answer:

$20,400\ cm^{3}$

Step-by-step explanation:

step 1

Find the volume of the tank

$V=(60)(15)(34)=30,600\ cm^{3}$

step 2

we know that

If the tank is 1/3 full of water

then

the volume of water required to completely fill the tank is equal to 2/3 of the tank capacity

$(2/3)30,600=20,400\ cm^{3}$

Please help me with this !:(

ahrayia [7]

Answer:

75.062c $m^{2}$

Step-by-step explanation:

To find the missing side use pythagorean theorem

So $6^{2} +b^2=8.5^2$

Solve for b, b= 6.021

To find the area use $\frac{1}{2}$ bh

So $\frac{1}{2}$ (6.021+19)(6)= area

And you get 75.062

Which expression is equivalent to -1/4( -1/2x - 3/4) -1/2 ( 3/4x + 1/8)

solniwko [45]

Answer:

Step-by-step explanation:

$\frac{-1}{4}(\frac{-1}{2}x-\frac{3}{4})-\frac{1}{2}(\frac{3}{4}x+\frac{1}{8})\\\\=\frac{-1}{4}*\frac{-1}{2}x-\frac{-1}{4}*\frac{3}{4}-\frac{1}{2}*\frac{3}{4}x-\frac{1}{2}*\frac{1}{8}\\\\=\frac{1}{8}x+\frac{3}{16}-\frac{3}{8}x-\frac{1}{16}\\\\=\frac{1}{8}x-\frac{3}{8}x+\frac{3}{16}-\frac{1}{16}\\\\=\frac{(1-3)x}{8}+\frac{3-1}{16}\\\\=\frac{-2}{8}x+\frac{2}{16}\\\\=\frac{-1}{4}x+\frac{1}{4}$
