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>
Answer:
1. the translation from the original to the translated figure was 2 units up and 1 unit to the left
2. the points of the translated figure if it were translated 2 units down and 3 units to the right would be: A' (4,0), B' (6,-6), C' (5,3), D' (-1,0)
Step-by-step explanation:
Answer:
A. 0.57
Step-by-step explanation:
150 did attend out of the two schools
200 did not
in total there are 350 students
200/350 is equal to 0.57142857
that rounded is 0.57
A is 0.57
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)
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°.
