Answer:

C)  The area of the landscape model is A = 40 sq ft.

Step-by-step explanation:

The original dimensions of the rectangular patio model  is

Length = L

Width = W

Area of the patio model  = LENGTH x WIDTH =   L  x W

⇒ A  =  L W .............  (1)

Now, the new area A" is enlarged by a factor of 2

⇒  The new Length = L"  = (2 L)

     The new Width  = W"  = (2 W)

So, AREA"  = L" x W" = (2 L) x (2 W)  = 4 (L W)

⇒  A "  =    4 (L W)

But, L W = A   .. from (1)

⇒   A"  = 4  A

But,  the area of the new enlarged patio is 160 square feet.

⇒   160 sq ft  = 4 x A

or, A   = 160 / 4 =40 sq ft

⇒ A = 40 sq ft.

Hence, the area of the landscape model is A = 40 sq ft.

A spirit shop outside the hockey stadium sells merchandise representing the three school districts that built the arena. The ent
Leokris [45]

The statue should be located at point E. Point E is the center of the circumscribed circle of the triangle created by the entrances to the arena, the spirit shop, and the parking lot. The distance from the statue to each vertex will then be equal to the radius of the circumscribed circle, so the statue will be at the same distance from all three landmarks.

Could someone please explain to me how to determine the answer to this question?
dexar [7]

Concept: Solution of the given attachment is based on the addition of two vectors as given below.

Consider two vectors P and Q, then resultant of these two vectors is given as,

R = P + Q

To find the addition of G & H vectors. That is G + H =?

In the given figure;

Vector A = - Vector G because both are in opposite directions -----(i)

From the figure,

A + H = F --------------- using the given concept ---------(ii)

Now, shall replace the value of A from equation (i) in equation(ii)

- G + H = F

or, G + (- H) = - F

Since the vector addition of G & H is not equal to F.

Hence, the given statement G + H = F is False.
