Tomorrow i have a math midterm at 11: 45a. m. and it is 9: 30 p. m. i am going over the material and i really don't know it. what should i do? ( i only have to be at school for the test so 2 hours)

You should try the best you can with whatever you got. Start with what you know and build from that to study in areas you aren't familiar with. Given the time constraints, you won't be able to get everything; however, you should be able to learn a few things, which is better than nothing. For any specific math questions you have, make a new post and I'll come take a look (or another helper will be able to help).

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
