The hypotenuse of a right triangle is twice the length of one of its legs. The length of the other leg is three feet. Find the l
aliya0001 [1]

a^2 + b^2 = c^2

Let c = hypotenuse = 2x

One of the legs = x. Let a or b = x.

I will let a = x. We can then say that b = 3.

3^2 + x^2 = (2x)^2

9 + x^2 = 4x^2

9 = 4x^2 - x^2

9 = 2x^2

9/2 = x^2

sqrt{9/2} = sqrt{x^2}

3/sqrt{2} = x

Rational denominator.

[3•sqrt{2}]/2 = x = a

Side 3 is given to be 3 feet. So, b = 3.

Hypotenuse = 2x

Hypotenuse = 2([3•sqrt{2}]/2)

Hypotenuse = 3•sqrt{2}

Understand?

The three sides are 3, [3•sqrt{2}]/2 and

3•sqrt{2}.

The rental rate for a cement mixer has a flat rate of $40 plus $20 for each day of the rental. The graph shows points representi
____ [38]

Answer:

y = 20x + 40

Step-by-step explanation:

Given that the rental rate for a cement mixer has a flat rate of $40 plus $20 for each day of the rental.

That means fixed one time cost is $40 which doesn't changes with time.

If number of days is represented by "x" then rental cost for "x" days will be 20 times x or just 20x.

So the final cost will be sum of fixed cost and the rental cost per day which is:

20x+40

Now if "y" represents total rental cost over time then final cost equation can be written as:

y = 20x + 40

Hence final answer is y = 20x + 40y = 20x + 40.
