What expression in terms of x can be used to represent the area of parallelogram PQRS?
Answers
Answer:
C. (5x√2)² = 50x²
Step-by-step explanation:
Area of parallelogram = QR²
QR = √((5x)² + (5x)²) ---› pythagorean theorem
QR = √(25x² + 25x²) =
QR = √(50x²)
QR = √(25*2*x²)
QR = 5x√2
✔️Area of parallelogram = QR²
= (5x√2)² = 25x² × 2 = 50x²

The circumference of the hub cap of a tire is 83.96 centimeters. Find the area of this hub cap. Use 3.14 for . Use pencil and paper. If the circumference of the hub cap were smaller, explain how this would change the area of the hub cap.
Answers
Answer:
Area = [tex]561.2485[/tex] square centimeter
If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.
Step-by-step explanation:
As we know the circumference of a circle is [tex]2\pi r[/tex]
The radius of the hub cap needs to be devised to determine the area
[tex]83.96[/tex] [tex]= 2* 3.14*r[/tex]
[tex]r = \frac{83.96}{2*3.14}[/tex]
[tex]r = 13.37[/tex] centimeters
Area of the hub cap = [tex]\pi r^{2}[/tex]
Substituting the devised value of r in the above equation, we get -
[tex]3.14 * 13.37^2\\[/tex]
[tex]561.2485[/tex] square centimeter
If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.

Answer:
Area of the side walk = 151 [tex]m^{2}[/tex]
Step-by-step explanation:
Given: Diameter of circular flower bed = 22 m
Width of circular side walk = 2 m
[tex]\pi[/tex] = 3.14
Area of the side walk = area of flower bed with side walk - Area of flower bed
Area of a circle = [tex]\pi[/tex][tex]r^{2}[/tex]
where r is the radius of the circle.
i. For the circular flower bed, diameter = 22 m. So that,
radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{22}{2}[/tex] = 11 m
Area of circular flower bed = [tex]\pi[/tex][tex]r^{2}[/tex]
= 3.14 x 11 x 11
= 379.94
Area of the circular flower bed = 380 [tex]m^{2}[/tex]
ii. For the flower bed with side walk, diameter = 26 m. So that,
radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{26}{2}[/tex] = 13 m
Area of flower bed with side walk = [tex]\pi[/tex][tex]r^{2}[/tex]
= 3.14 x 13 x 13
= 530.66
Area of flower bed with side walk = 531 [tex]m^{2}[/tex]
Area of the side walk = 531 - 380
= 151 [tex]m^{2}[/tex]

Step-by-step explanation:
The correct match for the data relationships in the image is as follows:
y does not change based on changes in z: No correlation
y tends to decrease as x increases: Negative correlation
tends to increase as x increases: Positive correlation
Here is an explanation of each of the matches:
Changes in z have no effect on y: This relationship demonstrates that y and z are not correlated. There is no obvious trend and the points are dispersed at random.
y tends to fall off as x rises: This association demonstrates that y and z do not correlate favorably. Y tends to decrease as x rises.
tends to grow as x gets bigger: This association demonstrates that y and z have a positive correlation. Y often rises as x rises.

Answers
Answer:
Step-by-step explanation:
Line AB is parallel to line CD (k) so they have the same slope.
slope=m=(y2-y1)/(x2-x1)
m=(6-0)/(4-0)
m=6/4=1.5
y=mx+b, we know m=1.5 so
y=1.5x+b, and we know it passes through point (4,0) so we can solve for b
0=1.5(4)+b
0=6+b
b=-6 so line k is
y=1.5x-6
The measure of one interior angle of a regular polygon is two times the measure of one of its exterior angles. How many sides does this polygon have?
Answers
Answer:
6 sides
Step-by-step explanation:
The measure of one interior angle of a regular polygon is two times the measure of one of its exterior angles. How many sides does this polygon have?
Let us represent:
Sum of Exterior angle as x
Sum of Interior angle as y
Note that:
The sum of the exterior angles of a polygon = 180 - The sum of the interior angles
Hence,
The sum of the exterior angles of a polygon + The sum of the interior angles = 180
x + y = 180
The measure of one interior angle of a regular polygon is two times the measure of one of its exterior angles.
2x = y
Substituting
x + 2x = 180°
3x = 180°
x = 180/3
x = 60°
Solving for y
2x = y
2 × 60° = y
120° = y
Hence,
Sum of Exterior angle as x = 60°
Sum of Interior angle as y = 120°
The number of sides of a polygon is
360°÷ Sum of Exterior angles
= 360° ÷ 60
= 6 sides
