Explain that you found the volume of water in the fish tank if it was only one and a half full with water show your work and sol

Reptile [31]

Answer:

The volume of water in the fish tank is 4.5 cubic feet

see the explanation

Step-by-step explanation:

The complete question is

Explain how you found the volume of water in the fish tank if it was only 1/2 full with water. Show your work and solution. Don't forget your UNITS!

You have a fish tank with the following dimensions:

Height: 3 feet

Width: 1.5 feet

Length: 2 feet

step 1

Find the volume of the fish tank

The volume of a rectangular prism ( fish tank) is equal to

$V=LWH$

substitute the given values

$V=(2)(1.5)(3)=9\ ft^3$

step 2

Find the volume of water in the fish tank

Remember that

The fish tank it was only one and a half full with water

Multiply the volume of the fish tank by one and a half to obtain the volume of water

$\frac{1}{2}(9)=4.5\ ft^3$

What is the square root of 5x^2 = 300

vesna_86 [32]

So, values of x are: $x=2\sqrt{15},\,\,x=-2\sqrt{15}$

Step-by-step explanation:

We need to find the square root of 5x^2 = 300

Writing in mathematical form:

$5x^2=300$

Divide both sides by 5

$\frac{5x^2}{5}=\frac{300}{5}$

$x^2=60$

Taking square root on both sides

$\sqrt{x^2}=\sqrt{60}$

$x=\pm (\sqrt{2\times 2\times 3\times 5})$

$x=\pm (\sqrt{2^2 \times 3\times 5})$

$x=\pm (2\sqrt{3\times 5})$

$x=\pm (2\sqrt{15})$

$x=2\sqrt{15},\,\,x=-2\sqrt{15}$

So, values of x are: $x=2\sqrt{15},\,\,x=-2\sqrt{15}$

What is the sum of entries a32 and b32 in A and B? (matrices)

Katyanochek1 [597]

Answer:

The correct answer is option D. 13

Step-by-step explanation:

From the figure we can see two matrices A and B

To find the sum of a₃₂ and b₃₂

From the given attached figure we get

a₃₂ means that the third row second column element in the matrix A

b₃₂ means that the third row second column element in the matrix B

a₃₂ = 4 and b₃₂ = 9

a₃₂ + b₃₂ = 4 + 9

= 13

The correct answer is option D. 13
