Step-by-step explanation
The desert basins of the Gobi are bounded by the Altai Mountains and the grasslands and steppes of Mongolia on the north, by the Taklamakan Desert to the west, by the Hexi Corridor and Tibetan Plateau to the southwest and by the North China Plain to the southeast.
The area of the <em>irregular</em> quadrilateral ABCD is equal to 234 square centimeters. (Correct choice: C)
<h3>What is the area of the quadrilateral?</h3>
Herein we have a description of an <em>irregular</em> quadrilateral, whose area must be determined by adding the areas of minor quadrilaterals and triangles that are part of it. The area is now determined:
A = 0.5 · (24 cm) · (7 cm) + 0.5 · (15 cm) · (20 cm)
A = 234 cm²
The area of the <em>irregular</em> quadrilateral ABCD is equal to 234 square centimeters. (Correct choice: C)

Answer:
D) 32π in³
Step-by-step explanation:
First, we find out what r is.
We can do that because we know the area when the radius is r.
This equation can be made: <em>4π = 4/3*πr³</em>
The π's and the 4 cancel out, which gives us: <em>1 = 1/3r³</em>
This gets us 3 = r³ --> <em>r = ∛3</em> (distance can't be negative)
Now, we can plug that into the equation again: <em>V = 4/3*π(2*√3)³</em>
<em>(2∛3)³ = 24 </em>--> <em>V = 4/3*π*24</em> --> <em>V = 96/3*π </em>--> V = 32π in³
Answer:
B. Keep the compass the same width, and place it on the other endpoint.
Step-by-step explanation:
Bisecting a segment implies dividing the segment into two equal parts. And to do this, the two endpoints of the segment are required.
Some of the steps required to bisect a segment are:
i. Place the compass on one of the endpoints and open to a radius larger than half of the segment.
ii. Describe an arc on either side of the segment.
iii. With the same radius, put the compass on the other endpoint of the segment.
iv. Describe an arc on either side of the segment to intersect the previous arcs.
v. Join the point of intersection of the arcs on the either side of the segment with a straight line.
Thus, the segment should have been bisected.
