Answer:
6.89
Step-by-step explanation:
(6.89+14.52)+(-14.52)
=6.89+14.52-14.52 First take away the parenthesis
=6.89 The positive and negative 14.52 cancel out
Here, trapezoid is composed of two triangles, and one rectangle.
So, Area of rectangle = 4 * 7 = 28 cm²
Area of a triangle = 1/2 * 3 * 7 = 21/2 = 10.5 cm²
Area of Trapezoid = area of rectangle + 2(area of triangle)
= 28 + 2(10.5)
= 28 + 21 = 49
In short, Your Answer would be 49 cm²

Answer:
6.347 g Zinc to the nearest thousandth.
Step-by-step explanation:
Using the molar atomic mass of the elements:
65.38 g Zinc produces 65.38 + 2(16 + 1.008) = 99.396 g Zn(OH)2
So by proportion amount of zinc required to produce 9,65 g Zn(OH)2
= (65.38/99.396) * 9.65 g Zinc
= 0.65777 * 9.65
= 6.347g Zinc.
