Answer:

2 hours for the 2 pipes

Step-by-step explanation:

1 pipe for a tank is 4 hours, but since 2 pipes is 2 hours less, it would take the two pipes together 2 hours

X = time it takes for the second pipe to fill the tank
x-2 = time it takes for both pipes to fill the tank
1/4 = portion of the tank filled by the first pipe in one hour
1/x = portion of the tank filled by the second pipe in one hour
1/(x-2) = portion of the tank filled by both pipes

Now you have your equation,
1/4 + 1/x = 1/(x-2)

You should be good now

Name the plane that is highlighted in the diagram below
larisa86 [58]

The plane that is highlighted inside the given cuboid is called a Rectangle.

<h3>What is the Plane in the given solid?</h3>

A cross-section is the intersection of a solid and a plane. Plane Figures and defined as solid shapes.

In geometry, shapes are the forms of objects which have boundary lines, angles and surfaces. These figures demonstrate the shape of objects we see in our everyday lives. There are different types of 2D shapes and 3D shapes. The plane shapes are two-dimensional closed shapes with no thickness and are known as 2D shapes.

Solid shapes are nothing but solids with three dimensions: length, breadth, and height. Solid shapes are also known as 3D shapes.

Now, looking at the given figure we see that it is a cuboid and we see that the 2 dimensional plane cut through it is clearly a rectangle.

Thus, we can conclude that the plane that is highlighted inside the given cuboid is called a Rectangle.

Make y the subject to the following questions
skelet666 [1.2K]
In this question it basically wants you to leave Y alone in a side of the equation.

In this case,
For 3y=c

y=\frac{c}{3}

For Ay=w

y=\frac{w}{A}

For Y/c=w
Y=cw

For y/a=2c
y=2ac

For a=y+p
y=a-p

For C=y-k
y=C+k

Find the Surface Area of the prism pleese
Alina [70]

Answer:

I'm unsure of the answer but here's how to solve it yourself :)

Step-by-step explanation:

area of a prism is obtained by taking the sum of (twice the base area) and (the lateral surface area of the prism). The surface area of a prism is given as S = (2 × Base Area) + (Base perimeter × height) where "S" is the surface area of the prism.
