Step-by-step explanation:
Answer:
C is my answer
Step-by-step explanation:
Answer:
Option B.
Step-by-step explanation:
Let the radius of the snare drum = r
and radius of the model = R
Ratio of the dimensions of the snare drum and the model = 1 : 4
So, 
Now as per question, dimensions of the snare drum is multiplied by a scale factor of 
Radius of the snare drum = 
Ratio of the radius of the snare drum and cylindrical model ,



Therefore, the cylinder with Sara's dimensions will be geometrically similar but the scale factor will be 1 : 2
Option B is the answer.
Answer:
A = 40.0 (3 sig. fig)
C = 40
c = 15
Step-by-step explanation:
Using sin law,
sinA/15 = sin100/23
A = 40.0 (3 sig. fig)
Using angle sum of triange,
C = 180 - 40.0 - 100 = 40
Since angleA = angleC, by side equal opp angles, c = 15
Answer: There are 60 different ways that he can arrange the books.
Step-by-step explanation:
Since we have given that
Number of computer science books = 5
Number of math books = 3
Number of books selected = 4
Atleast Number of computer science = 2
Atleast number of math book = 1
According to question, he wants at least two computer science books and at least one math book, and he wants to keep the computer science books and the math books together.
So, Number of different ways that he can arrange the books is given by

Hence, there are 60 different ways that he can arrange the books.
