is it possible to store a 20 foot long pipe in a rectangular room that is 10 feet by 12 feet by 8 feet?
Anastaziya [24]
First we'll consider the floor size.
In a 10 by 12 room the longest pipe that will fit lying on the floor equals the hypotenuse of a 10 by 12 triangle:
hypotenuse² = 10² + 12²
hypotenuse² = 100 + 144
hypotenuse² = 244
hypotenuse = <span> <span> <span> 15.62 feet

Now we have to consider the third dimension (height = 8 feet).
The two sides would be 15.62 and 8
</span></span></span>hypotenuse² = 15.62² + 8²
hypotenuse² = 244 + 64 = 308
hypotenuse = 17.55
So, the longest pipe that would fit in that room would be 17.55 feet long.

The total revenue for dante's villas is given as the function r(x)=300x−0.2x2, where x is the number of rooms filled. What numbe
FinnZ [79.3K]

Solution:- Given that the total revenue function

r(x)=300x-0.2x^2 ,where x is the number of rooms filled

Now, differentiating the function w.r.t. x,we get

r'(x)=300-0.4x

To find critical points ,Put r'(x)=0

\Rightarrow300-0.4x=0\\\Rightarrow0.4x=300\\\Rightarrow x=750\\\text{Now}\\r"(x)=-0.4

Suppose PR = 54, solve for QR<br> 4x-1<br> 3x-1<br> P<br> R
Svet_ta [14]

Answer:

QR = 23

Step-by-step explanation:

P, A, and R are collinear.

PR = 54

PQ = 4x - 1

QR = 3x - 1

To solve for the numerical length of PR, let's generate an equation to find the value of x.

According to the segment addition postulate:

PQ + QR = PR

(4x - 1) + (3x - 1) = 54 (substitution)

Solve for x

4x - 1 + 3x - 1 = 54

Combine like terms

4x + 3x - 1 - 1 = 54

7x - 2 = 54

Add 2 to both sides

7x - 2 + 2 = 54 + 2

7x = 56

Divide both sides by 7

\frac{7x}{7} = \frac{56}{7}

x = 8

QR = 3x - 1

Plug in the value of x into the equation

QR = 3(8) - 1 = 24 - 1

QR = 23

Write an equation that is parallel to y=-5/2x-5
NeX [460]

       A parallel equation (when graphed) will have the same slope, but a different y-intercept.

       As long as you keep y = -\frac{5}{2}x + b, you can input anything for b to solve this question.

       Given:

y = -\frac{5}{2}x - 5

       Equation of a parallel line:

y = -\frac{5}{2}x + 6, y = -\frac{5}{2}x + 1,356, y = -\frac{5}{2}x - 8, etc

     Example answer you can use:

             y = -\frac{5}{2}x - 8
