Perimeter = 2 * 85 + 2 * 125 = 420

85 * 125 = 10,625 area

70 by 140 = 420 perimeter

70 * 140 = 9,800 area

Kiana wants to cover a triangular area of her background with red, concrete patio stones. Each stone costs $0.42 and covers 29.2
Alex73 [517]
1. The problem says that the stone covers 29.26 square inches. So, the first thing you must do, is to convert 29.26 square inches (in²) to square feet (ft²):

 1 in²=0.00694 ft², then:

 29.26x0.00694= 0.20 ft²

 2. The triangular area has the following surface: 

 A=bxh/2
 A=(6 ft)(8 ft)/2
 A=24.0 ft²

 3. <span> Finally, the number of stones (N) that cover the triangular area is:
</span>
 N= 24.0 ft²/0.20 ft²
 N=120 stones

 Answer: <span>Kiana should buy 120 stones to cover the triangular area in her backyard.</span>

3x + y = 15 and y = 2x<br> The solution, given in (x,y) form is
rusak2 [61]

Answer: (3, 6)

Step-by-step explanation:

3x + y = 15

y = 2x

Using substitution:

3x + 2x = 15

5x = 15

x = 15/5

x = 3

y = 2x

y = 2 * 3

y = 6

x = 3

y = 6

= (3, 6)

In parallelogram ABCDABCD, ∠A∠A and ∠B∠B are adjacent. The measure of ∠B∠B is two times the measure of ∠A∠A. Which equation give
77julia77 [94]
Since adjacent angles in a parallelogram are supplementary (they add up to 180°), and ∠B is double as ∠A, you have this equation:

∠A + 2·∠A = 180°

From that you can find: 3·∠A = 180° ⇒ ∠A = 60°.
