Answer:

Step-by-step explanation:
By definition, similar polygons have corresponding sides in a constant proportion. Therefore, we can set up the following proportion (ratio of corresponding sides) to solve for
:

Step-by-step explanation:
Problem Green
Look at the white area. Where it meets the green border is the region of a quarter circle. So the quarter circle has a circumference of 1/4 * (2pi) r
r we are to take it, is 10/2 = 5 cm. It is 1/2 the side of the square..
So the perimeter of 1/4 green circle is (2/4) pi * 5 = 1/2 pi * 5 = 2.5*pi
There are 4 such areas.
So we have to multiply by 4
4 * 2.5 = 10 pi
The answer is 10*pi.
An alternate answer is 31.4 cm
Problem Two
<em><u>Large Circle</u></em>
Perimeter of the large circle = 2pi*r
r = 14 cm
Perimeter of the large circle= 2* pi * 14 = 28*pi
<em><u>Small Circle</u></em>
r = 14/2 = 7 cm
Perimeter = 2*pi*r
Perimeter = 2 * pi * 7
Perimeter = 14 pi
<em><u>Answer</u></em>
Total Perimeter = Small Circle + Big Circle
Total Perimeter = 14*pi + 28*pi = 42*pi
Your answer could be 42*3.14 = 131.88
If none of these are right, list your choices.
Answer:
84.13%
Step-by-step explanation:
Given data:
mean μ= 100 and standard deviation= 35
P(x>65)=
putting vales we get
P(z>(65-100)/35)=P(z>-1) or P(z<1).,
from normal distribution table we get
P(z<1)= 0.8413= 84.13%
Answer:
The correct option is option number 4. Parallel lines are defined as lines that never have one point in common.
Step-by-step explanation:
Parallel lines: Parallel lines are the lines that will never cross each other. As they never meet, so they won't have a common point.
On the other hand, the other options are incorrect. This is because,
Perpendicular lines: Perpendicular lines are the lines that make 90 degrees angle with each other.
Skew lines: Skew lines are the lines that are not present on the same plane.
Coplanar lines: Any lines which are known to occur on the same plane are termed as coplanar lines.
