Jamal spent 60 minutes using the computer to play games and do research for his report. he spent a half hour of the time playing games and the rest of the time researching his report. how many minutes did jamal spend researching his report

Five dinosaurs go for a walk and come across some lovely chicken wings. their names are rexy, bronto, steggy, paly, and terry. there are exactly 5 dozen wings(equal enough for each dino to have a dozen right? ); however, terry is on a diet and he only eats 6 wings. if paly eats 2 more than terry, steggy eats 4 more than paly, and bronto and rexy eat the same amount because they are really hungry from not eating all day, how many chicken wings did each dino eat?

If you had $1,900,000, how many days would it take you to spend all if you spent $1 a second. (there are 86,400 seconds in a day)

The difference of two numbers is 40. find the numbers if 0.3 parts of one number is equal to 37.5% of the other one.
