Answer:
12.5
Step-by-step explanation:
y varies inversely as x.
y = k/x
10 = k/20
200 = k
The constant proportion k is 200.
16 = 200/x
Cross multiply.
200 = 16x
200/16 = x
x = 12.5
C=(3.14)(15)
you multiply and get 47.1
the least common denominator for 32 and 64 is
Answer: 64
Answer:
1
Step-by-step explanation:
Let's start by prime factorizing (finding the prime factors) of 16 and 21:
![16=4*4=2*2*2*2=2^4](https://tex.z-dn.net/?f=16%3D4%2A4%3D2%2A2%2A2%2A2%3D2%5E4)
![21=3*7](https://tex.z-dn.net/?f=21%3D3%2A7)
We can see that they DO NOT have any common factors, meaning that their greatest common factor is 1.
