Professor Nonsense has a theory about how flowers grow. He believes that every night bugs tug at flowers to get them to grow and then open them carefully just before sunrise. He says that the dewdrops on flowers are actually drops of bug sweat. The professor tells about a small county in which dragonflies each open 6 roses, 4 daisies, and 6 daffodils per night; ladybugs each open 1 petunia, 2 pansies, and 1 tulip; moths each open 3 chrysanthemums and 5 violets; and bees each open 17 tiger lilies and 3 iris. Dragonflies deposit 10 sweat drops on each flower they open; ladybugs leave 5 drops, moths deposit 40 drops, and bees leave 15 drops. One morning last summer the professor counted 74,360 sweat drops on the flowers. He noticed four times as many 10-drop flowers as 5-drop flowers, and 3 times as many 15-drop flowers as 40-drop flowers. How many of each kind of insect had been working on the flowers the night before?

The equation for the decomposition of silver oxide is 2Ag2O---4Ag + O2. Set up a proportion to calculate the number of silver atoms produced and the number of oxygen molecules released when one g of silver oxide is broken down. There are 2.6 x 10 to the 21st power molecules in one g of silver oxide. Help me I'm so stuck................

Hey! I am stuck on this assignment! Any help would be appreciated!!

Ok so I have integers -4 to 4, set up in a round circle (ex: clock), and from the I have to obtain -10 to 10.. So for example, pretend i have a clock and it is from -4 to 4, now lets pretend i have 4 and 2 next to each other, so i get 6.
And say I have a 1 above the 4 so i have 1+4+2 which is 7, and I have 4+1 which is 5.

I tried, but there's always one number missing!! I AM BRAIN DEAD FROM THIS! HELP!!

THANK YOU!
