How many cubic feet are in 3 cubic yards?
dimaraw [331]
For every cubic yard, it equals to 27 cubic feet.

So, could have this fraction \frac{27 feet^3}{1 yards^3}
And we want to convert 3 cubic yards into cubic feet.

We can express 3 cubic yards as \frac{3 yards^3}{1}

Now multiply the \frac{3 yards^3}{1} fraction by the second fraction or the reciprocal of the second fraction to cancel out the yards^3 units.

\frac{3 yards^3}{1} * \frac{27 feet^3}{1 yards^2} =  \frac{81 feet^3}{1}

So, 3 cubic yards to equal to 81 cubic feet.

What are the steps to this
Mice21 [21]
If f(0) = -2 that means, when you put zero instead of x in the f(x) equation, it gives -2 as answer. m is given as 2/3. So,
f(x) = mx + b
f(0) = 2/3 * 0 + b = -2 then b = -2
Then you can write the general function as ;
f(x) = 2/3*m -2

And same steps for question 25;
m is given as -1/3

f(9) = -1/3 * 9 + b = 2 then b must be 5
Then the general form of the function;
f(x) = -1/3*m +5

The expression to find the perimeter of a rectangle is 2(length + width). What is the perimeter, in units, of a rectangle of len
Allisa [31]
First you plug in the data to the formula. So it will be 2(1/3+1/2). You then want to add the fractions together but must first find the common denominator which will be 6. So it is 2(2/6+3/6). The fractions then add up to be 5/6. So all you have to do is multiply it by 2 to get 5/3 which simplifies to 1 2/3 so it is D.
