Answer:

18 units

Step-by-step explanation:

Let's write out that perimeter formula: P = 2L + 2W.

Substitute 6 for L and 3 for W: P = 2(6) + 2(3) = 18 units.

One side of a right triangle has a length of 12 feet. Which of the following could be lengths for the two other sides of the rig

Elodia [21]

Answer:

B

Step-by-step explanation:

Apply the Pythagorean Theorem to determine whether or not the given triplets represent right triangles or not:

I. 5 feet and 13 feet: 5^2 + 12^2 = 13^2 is TRUE

II. 9 ft and √63 ft: 9^2, 63, 12^2: 63 + 81 do add up to 144 TRUE

III. 2, 10, 12^2: 2 + 10 do NOT add up to 144. FALSE

Answer B is correct

What is the value of x in the equation one-fifthx – two-thirdsy = 30, when y = 15? 4 8 80 200.

worty [1.4K]

On solving the linear system, for the value of y = 15, the value of x is 200. The correct option is D.

<h3>What is the linear system?</h3>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

The linear equation is shown below.

$\rm \dfrac{1}{5}x - \dfrac{2}{3}y = 30$

The equation can be written as

$\rm 3x - 10y = 450\\$

For y = 15, the value of x will be.

$\begin{aligned} \rm 3x - 10*15 &= 450\\\\\rm 3x - 150 &= 450 \\\\\rm 3x &= 600\\\\\rm x &= 200\\\end{aligned}$

The value of x is 200.

Thus, option D is correct.

A dog owner wants to use 200 ft of fencing to enclose the greatest possible area for his dog. he wants the fenced area to be rec

Fiesta28 [93]

Perimeter (P) = 2 · Length(L) + 2 · Width (W) → P = 2L + 2W
Solve for either L or W (I am solving for L).
200 - 2W = 2L
(200 - 2W)/2 = L
100 - W = L

Area (A) = Length (L) · Width (W)
= (100 - W) · W
      = 100W - W²

Find the derivative, set it equal to 0, and solve:
dA/dW = 100 - 2W
   0 = 100 - 2W
   W = 50

refer to the equation above for L:
100 - W = L
100 - 50 = L
      50 = L

Dimensions for the maximum Area are 50 ft x 50 ft
