Cody was 165cm tall on the first day of school this year, which was 10% taller than he was on the first day of school last year.

How tall was Cody on the first day of school last year?

  Let h be Codys height on the 1st day of school last year
h + 0.10h = 165
1.10h = 165
h = 165/1.10
h = 150cm

Solve this Problem Without Calculator   Answer: 80,173 Step-by-step explanation: We must use PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction). Since theres no parenthesis and exponent, we can proceed in multiplying. 352 × 228 - 54 + 3 - 32 × 1 = 80,256 - 54 + 3 - 32 = 80,202 + 3 - 32 = 80,205 - 32 = 80,173 #JuneChallenge

How do you graph these equations?   Answer: First, you substitute the values of x to the given equation. then plot the coordinates. Step-by-step explanation: For example in the table of values the first value of x that was given was -2. (x= -2). If you substitute -2 to the equation y=3/2x-1 becomes y=3/2(-2)-1. If you solve that the result would be y= -4. then yoll have (-2,-4). Then you basically plot that.

Deforestation And The Burning Of Fossil Fuels Have Impacted Global Temperatures And Increased Atmospheric Co2 Levels. How Has This Affected Ocean Curr

Deforestation and the burning of fossil fuels have impacted global temperatures and increased atmospheric CO2 levels. How has this affected ocean currents and acidified the ocean? What are some consequences of ocean acidification?   Answer & Explanation: It affects our seawater by making it more acidic and causes carbonated ions to be relatively less abundant because our ocean absorbs 30% of CO2 in the atmosphere and when the level of CO2 increases, the CO2 in the ocean also increases which results to a series of chemical reactions that increases the production of hydrogen ions. Ocean acidification may lead to the destruction of marine life because the increase in the acidity of the seawater makes it harder for corals to build it skeletons which is particularly important beacuse they provide a home for many other sea creatures.
