F, because the circles are open
Count the number of 1 bits after the last decimal point. Call this number n.
There will be 2^n subnets and 2^(8-n) - 2 hosts per subnet. (You can mutilply the number of subnets by the number of hosts per subnet to find the total number of hosts.)
/25: 255.255.255.128, 2 subnets, 126 hosts per subnet
/26: 255.255.255.192, 4 subnets, 62 hosts per subnet
/27: 255.255.255.224, 8 subnets, 30 hosts per subnet
/28: 255.255.255.240, 16 subnets, 14 hosts per subnet
/29: 255.255.255.248, 32 subnets, 6 hosts per subnet
Answer:
920*1.12^t
Step-by-step explanation:
Every year, we see that it goes up 12%.
12% in decimal form is 0.12.
Let's say we have "x" amount of cars one year. The next year, the number of cars will increase by 12%. 0.12x is added on after one year.
So in total, at the beginning of a new year, the number of cars is 0.12x+x = 1.12x.
In this case, we have 920 cars. So if every year the number of cars is multiplied by 1.12, then in "t" years we will have 920*(1.12)^t. We multiply by 920 because that's the current number of cars, and we add the ^t because we multiply by 1.12 every year.
You are very welcome!
