Answer:
Cross section
Step-by-step explanation:
When we slice a three-dimensional object, we expose new faces that are two dimensional. The two-dimensional face is called <u>cross section</u> .
Answer:
3.64 Km.
Step-by-step explanation:
Given,
Total population = 20,000 people
Population density = 480 people per square kilometer
Area of the circle town


Radius of the circle town


Hence, the radius of circle town is equal to 3.64 Km.
Answer:
B- Parallelogram PQRS is also a rhombus.
Step-by-step explanation:
Given
Parallelogram PQRS with perpendicular diagonals
Required
Which of the option is true
(a) PQRS can be a rectangle
A rectangle do not have perpendicular diagonals.
Hence, (a) is false
<em>If (a) is false, then (d) is also false</em>
(b) PQRS can a rhombus
The diagonals of a rhombus are not perpendicular.
So (b) <em>is true</em>
<em>No need to check for (c), since only option is true</em>
Answer:
f(x)=13x[+4. that one is the Correct answer. I hope it help.
Answer:
22.5° and 67.5°
Step-by-step explanation:
The sum of complementary angles equal 90°.
Given that one of the complementary angles is 3 times larger than the other, let "x" represent the other angle.
Thus, the following expression can be written to represent this case:

Solve for x

Divide both sides by 4


The measure of the complementary angles are:
x = 22.5°
3x = 3(22.5) = 67.5°
