Givens

  • A quadrilateral with four congruent angles, opposite sides congruent and parallel.

A quadrilateral with these characteristic is the rectangle, becuase all its for angles are equal to 90°, and opposite sides are parallel and congruent.

Therefore, the right answer is Rectangle.

Find the surface area of a sphere with a great circle that has an area of 49 π square miles.
Mademuasel [1]
The answer is <span>B. 196 π mi2
</span>
(1) Find radius r:
The area of the circle is:
A = r²π
A = 49π mi²

49π = r²π
49 = r²
r = √49 = 7 mi

(2) Find the surface area of the sphere.
The surface area of the sphere is: 
A = 4πr²
r = 7 mi
A = 4π * 7²
A = 4π * 49
A = 196π mi²

Assume for Namibia that the opportunity cost of each hut is 200 bowls. Then which of these pairs of points could be on Namibia's
Vaselesa [24]

The pairs that would be on Namibia's production possibilities frontier are (200 huts, 40,000 bowls) and (150 huts, 30,000 bowls) (option B).

<h3>What are the pairs on the possibilities frontier?</h3>

The Production possibilities frontiers is a curve that shows the various combination of two goods a company can produce when all its resources are fully utilised.

The PPC is concave to the origin. This means that as more quantities of a product is produced, the fewer resources it has available to produce another good.

Opportunity cost of the next best option forgone when one alternative is chosen over other alternatives. The pairs that would be on the frontier are the options that have an opportunity cost of 200 bowls when 1 hut is produced.

Opportunity cost of these pairs: (200 huts, 40,000 bowls) and (150 huts, 30,000 bowls)

  • Opportunity cost = 40,000 / 200 = 200
  • Opportunity cost = 30,000 / 150 = 200

Here is the complete question:
Assume for Namibia that the opportunity cost of each hut is 200 bowls. Which of these pairs of points could be on Namibia's production possibilities frontier?

a. (200 huts, 30,000 bowls) and (150 huts, 35,000 bowls)

b. (200 huts, 40,000 bowls) and (150 huts, 30,000 bowls)

c. (300 huts, 50,000 bowl) and (200 huts, 60,000 bowls)

d. (300 huts, 60,000 bowls) and (200 huts, 80,000 bowls)

(2x + y = -2<br> (5x + 3y = -8<br> Solve by substitution
aliya0001 [1]

(2, -6)

Step-by-step explanation:

y = -2 - 2x

5x + 3 (-2-2x) = - 8

5x - 6 - 6x = - 8

-x - 6 = 8

- 6 + 8 = x

2 = x

x = 2

y = -2 -2x

y = -2 -2(2)

y = -2 -4

y = -6

(x, y) = (2, -6)
