25th Billion App Download

I got the average by subtracting all the time zone numbers and the average is around 34,000. I divided 340,945,524 with 34,000 and got 10027.8 which I rounded up and got 10028. After that you divide by 60 and you should get 167. That means that we are only 167 hours away from the 25th billion download. There are 24 hours in a day so you divide 167 by 24 and should get 6.99999 and on. the download was around 24,658,000,000, and it started around 6:27 pm. I rounded up on 6.99999 and just made it 7 so I would start to download around 7 days which is a week so start downloading at 6:27 next week. The date would be February 31 when it hits the 25th billion download.

Slope of A Line Dawg

slope of a lineI find slope by looking at the the two points and moving up the lines to find the slope. The subtraction of it is (x,y) and after that you would go as a fraction and it would be y on on top and x on bottom. You would subtract both y’s together and then you would subtract both x’s together. Overall I feel like I can’t explain any better than that because it is so simple.

First Nine Weeks

I have enjoyed and learned a lot of things this year in math class. I have learned about combining like terms, negative numbers adding and subtracting them, and also rational and irrational numbers. I have gotten a few A’s and a few B’s on my tests. I am kind of upset because I’ve studied over the tests the second time and go the same grade on the re-take. I am disappointed in myself because I didn’t work hard enough this nine weeks to get that A. I am just gonna tell myself to work harder the next nine weeks and get that A.

Estimating the square root of 75

Today, I’m going to tell you how to estimate the square root of 75. First, you find the closest square roots to your other square root. Second, you try to find the middle between the two closest squares. The two squares for 75 is 64 and 81. Then you would use 8.5 because the middle of 8 and 9 is 8.5. Next, you would subtract 64.0 and 08.5. The answer would turn out to be 72.5. Then look to see if 75 is closer to 81 or 64.  75 is unfortunately closer to 81 than 64. I then would estimate my answer to around 8.7. I would check my answer to be around 75.69 so my answer is very close to my estimate.
