vivado [14]

Answer:

1 of 5) D, 2 of 5) B, 3 of 5) D, 4 of 5) A, 5 of 5) D

Explanation:

1 of 5) The composite area is the sum of the areas of two rectangles. That is:

$A = (4\,cm)\cdot (3\,cm) + (6\,cm)\cdot (2\,cm)$

$A = 12\,cm^{2}+12\,cm^{2}$

$A = 24\,cm^{2}$

The area of the shaded region is 24 square centimeters. (Answer: D)

2 of 5) The composite area is the sum of the areas of the rectangle and the triangle. That is:

$A = (8\,cm)\cdot (5\,cm)+\frac{1}{2}\cdot (5\,cm)\cdot (5\,cm)$

$A = 40\,cm^{2} + 12.5\,cm^{2}$

$A = 52.5\,cm^{2}$

The area of the shaded region is 52.5 square centimeters. (Answer: B)

3 of 5) The composite area is the sum of the areas of the rectangle and the triangle. That is:

$A = (10\,cm)\cdot (4\,cm)+ \frac{1}{2}\cdot (7\,cm)\cdot (6\,cm)$

$A = 40\,cm^{2}+21\,cm^{2}$

$A = 61\,cm^{2}$

The area of the shaded region is 61 square centimeters. (Answer: D)

4 of 5) The composite area is the sum of the areas of four triangles and two rectangles. That is:

$A = 4\cdot \frac{1}{2}\cdot (1\,m)\cdot (2\,m) + (8\,m)\cdot (4\,m)+(3\m)\cdot (1\,m)$

$A = 4\,m^{2}+32\,m^{2}+3\,m^{2}$

$A = 39\,m^{2}$

The area of the shaded region is 39 square meters. (Answers: A)

5 of 5) The composite area is the sum of the areas of the three semicircles and the square. That is:

$A =3\cdot \frac{\pi}{8}\cdot (10\,cm)^{2}+ (10\,cm)^{2}$

$A = 117.810\,cm^{2}+100\,cm^{2}$

$A = 217.810\,cm^{2}$

The area of the shaded region is 217.810 square centimeters. (Answer: D)

Why did the Romans see Carthage as a threat?

ella [17]

Carthage was a leader of trade and leadership. It was also the only city located near the Majardah River, Tunisia's only river to flow all year long. Many new cities replaced Carthage once it was taken over. It grew to be the second largest city in the western half of the Western Empire and was the center of the Roman Province in Africa. It was equally an early center for Christianity.
