Answer:</h2>
The area of the top surface of the washer is: 160.14 square mm.
<h2>
Step-by-step explanation:</h2>
The top of the surface is in the shape of a annulus with a outer radius of 10 mm and a inner radius of 7 mm ( since the diameter of the hole is: 14 mm and we know that the radius is half of the diameter)
Now, we know that the area of the annulus region is given by:
where R is the outer radius and r is the inner radius.
Here we have:
Hence, we have:
Answer:
B

Answer:
Step-by-step explanation:
A=number Adult tickets;S=A+74= number Student tickets
Total tickets=adult tickets + student tickets
724=A+(A+74)
724=2A+74 Subtract 74 from each side
650=2A divide each side by 2
325=A ANSWER 1: There were 325 Adult tickets sold
No because
15b + 4 = 25.6
15b = 21.6
b = 1.44
0.6+15b+4 = 25.6
4.6 + 15b = 25.6
15b = 21
b = 1.4
The answers are not the same therefore they are not equivalent.
