A sheet of paper is 8.5 in X 11 inches if you cut 2 in squared from each corner what is the area if the paper
IceJOKER [234]
A=length x height. First we want to know the area of the original sheet of paper. 8.5 x 11= 93.5 inches squared. Then we take two squares with side length 2 inches. The area of each of these squares is 2 x 2, or 4 inches. Since there are two, the total area we take away is 8 inches. We subtract 8 inches from 93.5 since we took it away, and the final area of the paper is 85.5 inches^{2}

Hope this helped!

the forecast calls for a 30% chance of snow today and a 40% chance of snow tomorrow. what are the chances it will rain two days
egoroff_w [7]

Answer:

The chances it will rain two days in a row is 12%

Step-by-step explanation:

The forecast calls for a 30% chance of snow today

So, chance of snowfall today = 30% = 0.3

A 40% chance of snow tomorrow.

So, chance of snowfall tomorrow= 40% = 0.4

The chances it will rain two days in a row = 0.4  \times 0.3

                                                                    = 0.12  

So, percent  it will rain two days in a row = 0.12 \times 100 = 12\%

Hence the chances it will rain two days in a row is 12%
