Document Summary

192. 168. 10. 0/25 borrowing 1 bit from the host portion. When you borrow a bit that bit can be either 0 or 1. 2^7 2^6 2^5 2^4 2^3 2^2 2^1 2^0. I have broken 256 hosts into 2 halves. How many combinations do i have now = 2^2 = 4. 2 bits here means 4 different combinations 4 subnets. Size of each subnet is 64 (or the smallest number borrowed) Number of hosts per subnet = 2^6 2 = 62. Ip address per subnet in /26 example == 64 ip address per subnet. Valid host / host per subnet in /26 example == 62 ip address per subnet. 64 ip address per subnet, 62 usable ip address or 62 valid hosts / hosts per subnet. Broadcast address of each subnet -> last ip address of a subnet. This means that 192. 168. 10. 63 is the broadcast address in the subnet (0->63). Account 30, eng 50, sales 100, hr 20.

Above are 6 tables of data from an experiment I performed. My goal is to determine the reaction order with respect to H2O2 and I- , the rate law for the reaction, and the activation energy for the reaction. My first issue is table #6. I do not believe that I have figured the correct (M) for the H2O2 and KI or the correct rate. I am supposed to make sure to express the concentrations based on the values after dilution due to mixing. I am not sure how to correctly calculate that.

I need these ratios:

Return on Assets

Return on Equity

Return on invested capital

Profit Margin

Gross Margin

Price to earnings

Asset Turnover

Fixed-Asset Turnover

Inventory Turnover

Collection Period

Days' sales in cash

Payables Period

Assets to Equity

Debt to assets

Debt to equity

Times Interest earned

Times Burden covered

Current Ratio

Acid Test

I need these calculated from bellow along with the common-sizeincome statement and common-size balance sheet from the five yearslisted below:
