In this case, we'll have to carry out several steps to find the solution.
Step 01:
data:
smaller square
side = 1 yd
larger square:
side = 4 yd
Step 02:
geometry:
perimeter:
larger square perimeter:
perimeter = s + s + s + s = 4s
perimeter = 4(4yd) = 16 yd
The answer is:
perimeter = 16 yd
Answer: 60 years
Step-by-step explanation:
Let x denotes the age of Demochares .
Time he spent as a boy = 
Time he spent as a youth = 
Time he spent as a man= 
Time he spent in dotage= 13 years
As per given , we have the following equation:

[Take LCM]





Hence, he is 60 years old.
Answer:
C. 30
Step-by-step explanation:
We have a list of names that need to be sorted in a specific order. For this, we will use a permutation. This can be found on a scientific calculator, however, I'll be using the equation.

n = total number of objects
r = number of objects selected
In this instance, n will equal 6 since we have 6 different names to choose from and r will equal 2 since we are picking two names. Enter the values into the equation and evaluate.

Therefore, there are 30 possible two-part names.
A ratio of 2:3 is the same as 2/3 now we can divide out 2/3 to .6666666 and then multiply by 10 to get 6.666666 or you could just multiply 10 x 2/3 to get 20/3 and then divide to get 6.66666.
Answer:
Whenever the earth, moon and sun are aligned, the gravitational pull of the moon is augmented by the gravitational pull of the sun, causing larger than average tidal ranges — meaning especially high high tides and very low low tides. These extreme tides are called “spring tides.”
