Answer:

23.3

(or 4\sqrt{34} (let me know if you wanted this one and is you want it explained) lol)

Step-by-step explanation:

To find the length of the fence, use the Pythagorean theorem because, if you cut a rectangle diagonally, you will create two right triangles, and this formula only works with right triangles:

a^{2} +b^{2} =c^{2}

Insert values:

12^{2} +20^{2} =c^{2}

Solve for c:

Evaluate exponents

144+400=c^2

Simplify addition

544=c^2

Find the square root of both

\sqrt{544} =\sqrt{c^2}\\\\\sqrt{544} =c\\\\23.324=c\\\\c=23.3

The fence needs to be approximately 23.3 m.

frez [133]
A = a^2.....where " a " is the size of 1 side
A = 256

256 = a^2...take sqrt of both sides, eliminating the ^2
sqrt 256 = a
16 = a

so each side is 16 ft....now we find the perimeter
P = 4a....where " a " is the size of each side
P = 4(16)
P =  64.......so they will need 64 ft of fencing <===

A grocery store has 120 bottles of spring
notka56 [123]

Question:

A grocery store has 120 bottles of spring water in stock.  The store orders bottles of spring water in cases of 24.  The store wants to order enough cases of spring water so it has more than 500 bottles in stock.  Which inequality best models this situation?

A.  24x + 120 > 500

B.  24x - 120 > 500

C.  24x + 500 > 120

D.  24(x+120) > 500

Answer:

Option  A.  24x + 120 > 500  is the inequality that best models this situation.

Step-by-step explanation:

The Number of bottles of spring  water in the stock = 120

Each case of the spring water bottles contains 24 bottles

The store wants  to order enough cases of spring water so  that it has over 500 bottles in stock.

So there are already 120 bottles in stock .

The store will order

24x +120  > 500

where x  is the number of spring water bottle cases
