18 - 20. You%26#039;re on your own - I did enough



Please help me I am homeschooled and failing math I need to have these answered because if I don%26#039;t...?

holy moo-moo, that is a lot:



Question 1:



Use V = (1/3)bh



Solve for b.



you need to multiply both sides by 3:



3V = 3/3 bh



3V = bh



now divide both sides by h:



3V/h = b (answer)



as for the rest of them, some other sucker will have to do.|||That%26#039;s asking a bit much of people don%26#039;t you think? You should ask your mom or teacher for help.|||Ok, question 3.



Let%26#039;s image you are going to your friend%26#039;s house - 2 miles away, and you walk at 4 miles and hour. So in 1 hour you%26#039;ll go 4 miles - therefore it%26#039;ll take you 1/2 hour to go 2 miles.



Now let%26#039;s think about the question -



Destiny drove to Alyssa%26#039;s house at 52 mph. Alyssa%26#039;s house is 128 miles away. How long did it take her to get to Alyssa%26#039;s house?



SHe%26#039;s travelling 52 miles every hour. How many 52s are there in 128? THat%26#039;s how many hours it will take. (Use your calculator to divide 128 by 52)



Now you can do Q 4 as well|||A, B, 2.46 hours, 5.78 hours, 44 cm, 48.4 cm, 7.5 cm, 2/3 cm, 3 cm, 7 m, 3.75 hours, 333 mph, 20 degrees celsius, 25 kph. The rest u do urself cuz thats a lot
