Answer:
1/2
Step-by-step explanation:
First square area = 4cm^2, thus the side length is 2cm
Second square area = 16cm^2, thus the side length is 4cm
This gives a ratio of 2/4, simplifying yields 1/2
Answer:

Step-by-step explanation:

Convert the above mixed numbers to improper fractions through this simple approach: 3 × 10 + 1 /10 = 31/10. Similarly, 2 × 6 + 5 /6 = 17/6

Take the LCM of the denominators and simplify. LCM = 60. Thus, 60/10 = 6; 6 × 31 = 186. Also, 60/6 =10; 10×17 =170 all divide by 60:

Common factors between the numerator and denominator is 4, therefore 16/4 = 4 and 60/4 = 15.

Therefore the answer is 4/15 in simplest form.
Answer:
the first one has one solution because eventually they will cross
Yes, these both are direct relationships and can be written like

, where k is the constant of variation.
For the first equation, k = 10. For the second equation, k = -4/3. You find it by rearranging the equation into the form

, and you use the coefficient of x for k.
Answer:
C. It is used to find the sum of interior angles
Also , it can be used to find the number of triangles in the polygon,
Step-by-step explanation:
Example :
Find the sum of interior angles whose no of sides is 6 and give the name of the polygon
<u>Solution</u>
<u>S = (n-2)180° </u>
S = (6-2)180°
S = (4)180°
S = 720°
The polygon is a Hexagon
I hope it helps :)
